    An international team of astronomers using the NASA/ESA Hubble Space Telescope has made new measurements of Uranus’ interior rotation rate with a novel technique, achieving a level of accuracy 1,000 times greater than previous estimates. By analyzing more than a decade of Hubble observations of Uranus’ aurorae, researchers have refined the planet’s rotation period and established a crucial new reference point for future planetary research.

    Determining a planet’s interior rotation rate is challenging, particularly for a world like Uranus, where direct measurements are not possible. A team led by Laurent Lamy (of LIRA, Observatoire de Paris-PSL and LAM, Aix-Marseille Univ., France), developed an innovative method to track the rotational motion of Uranus’ aurorae: spectacular light displays generated in the upper atmosphere by the influx of energetic particles near the planet’s magnetic poles. This technique revealed that Uranus completes a full rotation in 17 hours, 14 minutes, and 52 seconds — 28 seconds longer than the estimate obtained by NASA’s Voyager 2 during its 1986 flyby.

    “Our measurement not only provides an essential reference for the planetary science community but also resolves a long-standing issue: previous coordinate systems based on outdated rotation periods quickly became inaccurate, making it impossible to track Uranus’ magnetic poles over time,” explains Lamy. “With this new longitude system, we can now compare auroral observations spanning nearly 40 years and even plan for the upcoming Uranus mission.”

    This Hubble image shows Uranus and dynamic aurora activity on 10 October 2022. The planet is dominated by a blue hue and a large white region in the lower left. A faint ring is also visible around the planet. Fuzzy blue/purple regions hovering over the planet on the left and ride indicate the presence of aurorae.

    This breakthrough was possible thanks to Hubble’s long-term monitoring of Uranus. Over more than a decade, Hubble has regularly observed its ultraviolet auroral emissions, enabling researchers to produce magnetic field models that successfully match the changing position of the magnetic poles with time.

    “The continuous observations from Hubble were crucial,” says Lamy. “Without this wealth of data, it would have been impossible to detect the periodic signal with the level of accuracy we achieved.”

    Unlike the aurorae of Earth, Jupiter, or Saturn, Uranus’ aurorae behave in a unique and unpredictable manner. This is due to the planet’s highly tilted magnetic field, which is significantly offset from its rotational axis. The findings not only help astronomers understand Uranus’ magnetosphere but also provide vital information for future missions.

    These findings set the stage for further studies that will deepen our understanding of one of the most mysterious planets in the Solar System. With its ability to monitor celestial bodies over decades, the Hubble Space Telescope continues to be an indispensable tool for planetary science, paving the way for the next era of exploration at Uranus.

    These results are based on observations acquired with Hubble programs GO #12601, 13012, 14036, 16313 and DDT #15380 (PI: L. Lamy). The team’s paper was published in Nature Astronomy.

    The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

    NASA Science Supports Data Literacy for K-12 Students

    Data – and our ability to understand and use it – shapes nearly every aspect of our world, from decisions in our lives to the skills we need in the workplace and more. All of us, as either producers or consumers of data, will experience how it can be used to problem-solve and think critically as we navigate the world around us. For that reason, Data Science has become an increasingly essential and growing field that combines the collection, organization, analysis, interpretation, and sharing of data in virtually every area of life. As more data become more openly available, our Data Science skills will be of increasing importance. And yet, there is a widening gap between what students learn in school and the skills they will need to succeed in a data-driven world. The integration of Data Science into K-12 education opens doors to higher education, high-paying careers, and empowering learners to eventually participate in the creation of new knowledge and understanding of our world, and at least 29 states have reported some level of data science implementation at the K-12 level, including standard or framework adoption, course piloting, and educator professional learning.

    In February 2025, the first-ever Data Science Education K-12: Research to Practice Conference (DS4E) took place in San Antonio, TX. A number of representatives from NASA’s Science Activation program and other NASA partners attended and presented along with over 250 educators, researchers, and school leaders from across the nation. Science Activation projects share a passion for helping people of all ages and backgrounds connect with NASA science experts, content, experiences, and learning resources, and the AEROKATS & ROVER Education Network (AREN); Place-Based Learning to Advance Connections, Education, and Stewardship (PLACES); Global Learning and Observations to Benefit the Environment (GLOBE) Mission Earth; and My NASA Data teams did just that. Their presentations at the conference included:

    • “BYOD – Build or Bring Your Own Data: Developing K-12 Datasets” (PLACES)
    • “Using NASA Data Resources as a Tool to Support Storytelling with Data in K-12 Education” (My NASA Data)
    • “Place-Based Data Literacy: Real People, Real Places, Real Data” (AREN)

    Conference participants expressed interest in learning more about NASA assets, including data and subject matter experts. Stemming from their participation in this first DS4E, several Science Activation teams are collaborating to potentially host regional events next year under the umbrella of this effort (PLACES in particular), a wonderful example of how Science Activation project teams help lead the charge in the advancement of key Science, Technology, Education, and Mathematics (STEM) fields, such as Data Science, to activate minds and promote a deeper understanding of our world and beyond.

  • Mike Drury: A 40-Year Legacy of Precision

    Deputy Integration and Testing Manager – Goddard Space Flight Center

    Mike Drury began at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, as a temporary technician — a contractor hired for six weeks to set up High Capacity Centrifuge tests. Six weeks then turned into three months and, eventually, over 40 years.

    Portrait of Mike Drury

    Now, Mike is the deputy integration and testing manager for NASA’s Nancy Grace Roman Space Telescope. In this role, Mike oversees both Roman’s assembly and the many verification processes that ensure it is ready for launch.

    “It’s a privilege to work here. There’s really no regrets,” Mike says. “This is a big place, and it is what you make it. You can really spread your wings and go into a lot of different areas and do different things.”

    When Mike first began at Goddard, only government-employed technicians could work on space flight hardware. However, times were changing. The “old-timers,” as Mike affectionately calls them, soon began training a small group of contractors, including Mike, for flight hardware work. Mike credits these “old-timers” for the mindset he still carries decades later.

    “They taught me how to approach things and execute, and that helped me through my entire career,” Mike says. “It’s that approach — making sure things are done right, without cutting any corners — that I always liked about working here.”

    Not everyone can say that they worked on space missions while in college, but Mike can. Mike took advantage of a program through his contract that paid for classes. For 10 years, Mike studied at Anne Arundel Community College while continuing full-time work at Goddard, eventually earning an associate’s degree in mathematics. 

    While in community college, Mike also stocked up on several physics and calculus credits which helped prepare him to study thermal engineering at Johns Hopkins University. After seven more years of night classes, Mike completed a bachelor’s degree in mechanical engineering. 

    “Night school was really difficult between full-time work and traveling because I was working on several missions,” Mike says. “You needed that perseverance to just keep going and working away at it. So I just hung in there.”

    NASA

    In his 17 years of night school, Mike worked on seven missions, expanding his skill set from test set-up, to clean room tech work, to training astronauts. While working on the Hubble Space Telescope, Mike helped to train astronauts for their in-orbit tech work to install various instruments. 

    “Every mission I’ve worked on I’ve learned something,” Mike says. “Every test you learn more and more about other disciplines.”

    After graduating from Johns Hopkins, Mike worked for a short time as an engineer before becoming an integration supervisor. In 2006, Mike took on the position of James Webb Space Telescope ISIM (Integrated Science Instrument Module) integration and test manager. After Webb’s ISIM was integrated with the Optical Telescope Element, Mike became the OTIS (Optical Telescope Element and Integrated Science Instrument Module) integration and testing manager.

    “It was a tough eight to 10 years of work,” Mike says. “Loading the OTIS into the shipping container to be sent to NASA’s Johnson Space Center in Houston for further testing was a great accomplishment.” 

    To ensure that Webb’s ISIM would thrive in space, Mike was involved in more than three months of round-the-clock thermal vacuum testing. During this time, a blizzard stranded Mike and others on-site at Goddard for three days. Mike spent his nights overseeing thermal vacuum tests and his days driving test directors and operators to their nearby hotel rooms with his four-wheel-drive truck — a winter storm savior in short supply.

    In this 1992 picture, Mike works alongside another technician on DXS (Diffuse X-Ray Spectrometer) in the shuttle bay at NASA’s Kennedy Space Center in Florida. DXS was a University of Wisconsin-Madison experiment flown during the January 1993 flight of NASA’s Space Shuttle Endeavor.
    NASA

    For Mike, the hard work behind space missions is well worth it.

    “As humans, we want to discover new things and see things. That’s what keeps me coming back — the thought of discovery and space flight,” Mike says. “I get excited talking to some of the Hubble or Webb scientists about the discoveries they’ve made. They answer questions but they also find themselves asking new ones.”

    Some of these new questions opened by Hubble and Webb will be addressed by Mike’s current project — Roman.

    “This team I would say is the best I’ve ever worked with. I say that because it’s the Goddard family. Everyone here on Roman has the same agenda, and that’s a successful, on-time launch,” Mike says. “My ultimate goal is to be staying on the beach in Florida after watching Roman blast off. That would be all the icing on the cake.”

    Mike is also focusing on laying the groundwork for the next era at Goddard. He works hard to instill a sense of import, intention, and precision in his successors, just as the “old-timers” instilled in him 40 years ago.

    “I talk to a lot of my colleagues that I’ve worked with for years, and we’re all excited to hand it off to the next generation,” Mike says. “It’s so exciting to see. I’m the old guy now.”

    Written by Catherine O’Connell-Cooper, Planetary Geologist at University of New Brunswick

    Earth planning date: Monday, April 7, 2025

    Over the weekend, we completed our drive up the steep side of a canyon, up onto “Devil’s Gate,” a small butte which forms part of the ridge along the top of the canyon and now we can see down into the next canyon. It is always true that we are going somewhere no one has been before – that’s the idea of an exploratory mission after all, and everyone kind of gets used to it, we don’t stop to think about it. But today, coming over the top of a hill like this and fully looking for the first time into an area that we have only had glimpses of before, it really brings it home that the mission is doing something extraordinary, something out of this world …. and brings that feeling of awe back into focus. 

    We did not pass SRAP (Slip Risk Assessment Process) a couple of times as we climbed up the side of this canyon, meaning that the contact science instruments (APXS and MAHLI) had to stand down for that day’s planning. However, this morning, in addition to a brand new vista, we saw that all six wheels are firmly on the ground and we passed SRAP quickly this morning, which must have been a relief to the rover planner in charge of assessing it today! (no one wants to be the bearer of bad news, day after day!) 

    Bedrock here has both flat bedrock and amazing large nodular features, which appear to have “wind tails” caused by winds consistently blowing in the same direction. This is a Touch and Go plan, so APXS and MAHLI are focusing on a single target, the brushed “Coronado” target on the flat bedrock in front of us. ChemCam will use LIBS to investigate the nodular features at “La Cumbre Peak.”  

    Near the rover, Mastcam will image some small diagenetic features at “Boulder Oaks” and the LIBS target. The 3×2 (2 rows of 3 images) “La Jolla Valley” mosaic focuses on a very nodular patch, just outside of the workspace reachable by the arm. Further from the rover, the 6×2 mosaic (2 rows of 6 images) “Los Penasquitos” looks at an amazing almost vertical vein. This discontinuous vein stretches for about 6 meters (about 18 feet), with vein fins sticking above the surface at various points, like a series of shark fins breaking the bedrock surface. Much further afield, ChemCam will acquire a long distance image on “Condor Peak,” which appears to have large scale vein networks, known as “boxwork structures” and may be an early example of the boxworks we are hoping to reach in Fall 2025.  

    The ENV (Environmental and Atmospheric group) planned a Mastcam “tau” measurement, to look at dust in the atmosphere. There is a paired Navcam activity, looking at dust devils towards the north of the crater on the first sol and towards the south on the second sol. A suprahorizon movie and our usual DAN and REMS measurements round out this plan.  

    Let’s see what the next drive will reveal to us!

    Have you ever wondered how NASA manages to achieve all the incredible missions it does, like probing the Sun and studying the history of our Universe? We do it through teamwork, one of our core values. And an essential part of NASA’s team is what we call Mission Support. Mission Support makes sure NASA’s missions, centers, and programs have the capabilities and services they need to explore the unknown, innovate for the future, and inspire the world.  

    To illustrate Mission Support at NASA, look at the example of the Roman Space Telescope. It’s not just scientists and engineers who are making the telescope happen. The program works with NASA’s financial office to plan the budget for the telescope. Engineers design the telescope with tools developed in coordination with NASA’s shared services and information technology offices. NASA’s engineering authority checks the design, and international relations manages NASA’s collaborations with other countries on the telescope. All of this is Mission Support. 

    Of course, there is much more to Mission Support, but I think you get the picture. MSD enables Mission Support by:  

    • Planning and executing the Mission Support budgets for safety, security, and mission services as well as construction and environmental management.  
    • Executing strategy and governance to ensure Mission Support is financially sound, aligned with the agency’s goals, and serving NASA’s missions. 
    • Addressing Mission Support’s financial, operational, legal, and reputational risks to ensure resilience and mission success. 
    • Working with mission directorates and centers to ensure NASA is prioritizing the Mission Support services they need most urgently to be successful. 
    • Integrating Mission Support services across the agency to maximize efficiency and effectiveness. 

    Current and future missions require significant support to be successful. MSD is working today to ensure Mission Support is there for NASA to explore the unknown, innovate for the future, and inspire the world.

    Deep Space Station 43 (DSS-43), a 230-foot-wide (70-meter-wide) radio antenna at NASA’s Deep Space Network facility in Canberra, Australia, is seen in this March 4, 2020, image. DSS-43 was more than six times as sensitive as the original antenna at the Canberra complex, so it could communicate with spacecraft at greater distances from Earth. In fact, Canberra is the only complex that can send commands to, and receive data from, Voyager 2 as it heads south almost 13 billion miles (21 billion kilometers) through interstellar space. More than 15 billion miles (24 billion kilometers) away, Voyager 1 sends its data down to the Madrid and Goldstone complexes, but it, too, can only receive commands via Canberra.

    As the Canberra facility celebrated its 60th anniversary on March 19, 2025, work began on a new radio antenna. Canberra’s newest addition, Deep Space Station 33, will be a 112-foot-wide (34-meter-wide) multifrequency beam-waveguide antenna. Buried mostly below ground, a massive concrete pedestal will house cutting-edge electronics and receivers in a climate-controlled room and provide a sturdy base for the reflector dish, which will rotate during operations on a steel platform called an alidade.

    When it goes online in 2029, the new Canberra dish will be the last of six parabolic dishes constructed under NASA’s Deep Space Network Aperture Enhancement Program, which is helping to support current and future spacecraft and the increased volume of data they provide. The network’s Madrid facility christened a new dish in 2022, and the Goldstone, California, facility is putting the finishing touches on a new antenna.

    Findings from the Field: A Research Symposium for Student Scientists

    Within the scientific community, peer review has become the process norm for which an author’s research or ideas undergo careful examination by other experts in their field. It encourages each scientist to meet the high standards that they themselves, as writers and reviewers, have aided in setting. It has become essential to the academic writing practice.

    Historically, the peer review process has been limited to higher education and scholars more established in their academic careers. It has been required by only the more reputable publications, which can mean that lesser-known journals that don’t require this rigorous peer review process contain lower quality or less reliable information.

    In an effort to give scientists of all ages the opportunity to participate in and contribute to the advancement of human knowledge in a meaningful and reliable way, the Gulf of Maine Research Institute (GMRI) began publishing Findings from the Field, a journal of student ecological and environmental science, launched in 2017. Students conduct authentic scientific inquiry, subject their research to the peer review process, and submit their revised work for editorial board review before publication—the same process a NASA scientist must go through! This hands-on, real-world experience in scientific communication sharpens these young scientists’ skills and immerses them in the collaborative nature of research—an essential foundation for the next generation of scientists.

    After 7 years and 7 published volumes, Findings from the Field was ready to expand, and the Findings Student Research Symposium was launched. The Symposium was a success from the start, with 65 student scientists joining the event the first year and attendance climbing to 95 for year two. On March 10, 2025, GMRI (the anchor institution for the NASA Science Activation program’s Learning Ecosystems Northeast (LENE) project) welcomed nearly 100 young scientists, ranging from grades 5-12. These students, representing eight schools across Maine and New Hampshire, came together to share their research and engage in an evolving, intergenerational scientific community—one that fosters curiosity, collaboration, and scientific discovery.

    Students presented their research through posters and live presentations, covering topics ranging from invasive green crab species, to the changing landscapes of Ash and Hemlock trees, and more. By connecting students with professional researchers, fostering peer discussions, and providing a platform for publishing legitimate scientific work, the Findings Symposium is a launch pad for the future of the scientific community.

    One important element of the Symposium is the opportunity for young scientists to dialogue with professional scientists. Students engaged with researchers from Markus Frederich’s lab at the University of New England, volunteers from local organizations like Unum and Avangrid, and expert staff from GMRI.

    Student Madalyn Bartlett from Sacoppee Valley Middle School shared, “It makes me feel really proud, because I get to talk to professional scientists that have a lot of experience in this, and it make me feel like I am contributing to something bigger than my school and my community.”

    These interactions emphasize that science isn’t confined to white coats and labs—it’s about curiosity, observation, and shared knowledge. The keynote speaker, Kat Gardner-Vandy from a former NASA Science Activation project team, Native Earth | Native Sky, reinforced this message, inspiring students to see themselves as vital contributors to science and our collective knowledge about the world.

    The Learning Ecosystems Northeast project is supported by NASA under cooperative agreement award number NNX16AB94A and is part of NASA’s Science Activation Portfolio. Learn more about Learning Ecosystems Northeast: https://www.learningecosystemsnortheast.org/

  • NASA’s First Flight With Crew Important Step on Long-term Return to the Moon, Missions to Mars

    Houston We Have a Podcast: Ep. 283: The Artemis II Astronauts

    The Artemis II test flight will be NASA’s first mission with crew under Artemis. Astronauts on their first flight aboard NASA’s Orion spacecraft will confirm all of the spacecraft’s systems operate as designed with crew aboard in the actual environment of deep space.  Through the Artemis campaign, NASA will send astronauts to explore the Moon for scientific discovery, economic benefits, and to build the foundation for the first crewed missions to Mars – for the benefit of all.

    The unique Artemis II mission profile will build upon the uncrewed Artemis I flight test by demonstrating a broad range of SLS (Space Launch System) and Orion capabilities needed on deep space missions. This mission will prove Orion’s critical life support systems are ready to sustain our astronauts on longer duration missions ahead and allow the crew to practice operations essential to the success of Artemis III and beyond.

    Leaving Earth

    The mission will launch a crew of four astronauts from NASA’s Kennedy Space Center in Florida on a Block 1 configuration of the SLS rocket. Orion will perform multiple maneuvers to raise its orbit around Earth and eventually place the crew on a lunar free return trajectory in which Earth’s gravity will naturally pull Orion back home after flying by the Moon. The Artemis II astronauts are NASA’s Reid Wiseman, Victor Glover, and Christina Koch, and CSA (Canadian Space Agency) astronaut Jeremy Hansen.

    The initial launch will be similar to Artemis I as SLS lofts Orion into space, and then jettisons the boosters, service module panels, and launch abort system, before the core stage engines shut down and the core stage separates from the upper stage and the spacecraft. With crew aboard this mission, Orion and the upper stage, called the interim cryogenic propulsion stage (ICPS), will then orbit Earth twice to ensure Orion’s systems are working as expected while still close to home. The spacecraft will first reach an initial orbit, flying in the shape of an ellipse, at an altitude of about 115 by 1,400 miles. The orbit will last a little over 90 minutes and will include the first firing of the ICPS to maintain Orion’s path. After the first orbit, the ICPS will raise Orion to a high-Earth orbit. This maneuver will enable the spacecraft to build up enough speed for the eventual push toward the Moon. The second, larger orbit will take approximately 23.5 hours with Orion flying in an ellipse between about 115 and 46,000 miles above Earth. For perspective, the International Space Station flies a nearly circular Earth orbit about 250 miles above our planet. 

    After the burn to enter high-Earth orbit, Orion will separate from the upper stage. The expended stage will have one final use before it is disposed through Earth’s atmosphere—the crew will use it as a target for a proximity operations demonstration. During the demonstration, mission controllers at NASA’s Johnson Space Center in Houston will monitor Orion as the astronauts transition the spacecraft to manual mode and pilot Orion’s flight path and orientation. The crew will use Orion’s onboard cameras and the view from the spacecraft’s windows to line up with the ICPS as they approach and back away from the stage to assess Orion’s handling qualities and related hardware and software. This demonstration will provide performance data and operational experience that cannot be readily gained on the ground in preparation for critical rendezvous, proximity operations and docking, as well as undocking operations in lunar orbit beginning on Artemis III.

    Checking Critical Systems

    Following the proximity operations demonstration, the crew will turn control of Orion back to mission controllers at Johnson and spend the remainder of the orbit verifying spacecraft system performance in the space environment. They will remove the Orion Crew Survival System suit they wear for launch and spend the remainder of the in-space mission in plain clothes, until they don their suits again to prepare for reentry into Earth’s atmosphere and recovery from the ocean.

    While still close to Earth, the crew will assess the performance of the life support systems necessary to generate breathable air and remove the carbon dioxide and water vapor produced when the astronauts breathe, talk, or exercise. The long orbital period around Earth provides an opportunity to test the systems during exercise periods, where the crew’s metabolic rate is the highest, and a sleep period, where the crew’s metabolic rate is the lowest. A change between the suit mode and cabin mode in the life support system, as well as performance of the system during exercise and sleep periods, will confirm the full range of life support system capabilities and ensure readiness for the lunar flyby portion of the mission.

    Orion will also checkout the communication and navigation systems to confirm they are ready for the trip to the Moon. While still in the elliptical orbit around Earth, Orion will briefly fly beyond the range of GPS satellites and the Tracking and Data Relay Satellites of NASA’s Space Network to allow an early checkout of agency’s Deep Space Network communication and navigation capabilities. When Orion travels out to and around the Moon, mission control will depend on the Deep Space Network to communicate with the astronauts, send imagery to Earth, and command the spacecraft.

    After completing checkout procedures, Orion will perform the next propulsion move, called the translunar injection (TLI) burn. With the ICPS having done most of the work to put Orion into a high-Earth orbit, the service module will provide the last push needed to put Orion on a path toward the Moon. The TLI burn will send crew on an outbound trip of about four days and around the backside of the Moon where they will ultimately create a figure eight extending over 230,000 miles from Earth before Orion returns home.

    To the Moon and “Free” Ride Home

    On the remainder of the trip, astronauts will continue to evaluate the spacecraft’s systems, including demonstrating Earth departure and return operations, practicing emergency procedures, and testing the radiation shelter, among other activities.

    The Artemis II crew will travel approximately 4,600 miles beyond the far side of the Moon. From this vantage point, they will be able to see the Earth and the Moon from Orion’s windows, with the Moon close in the foreground and the Earth nearly a quarter-million miles in the background.

    With a return trip of about four days, the mission is expected to last about 10 days. Instead of requiring propulsion on the return, this fuel-efficient trajectory harnesses the Earth-Moon gravity field, ensuring that—after its trip around the far side of the Moon—Orion will be pulled back naturally by Earth’s gravity for the free return portion of the mission.

    Two Missions, Two Different Trajectories

    Following Artemis II, Orion and its crew will once again travel to the Moon, this time to make history when the next astronauts walk on the lunar surface. Beginning with Artemis III, missions will focus on establishing surface capabilities and building Gateway in orbit around the Moon.

    Through Artemis, NASA will explore more of the Moon than ever before and create an enduring presence in deep space.

  • NASA’s Deep Space Network Starts New Dish, Marks 60 Years in Australia

    4 min read

    Preparations for Next Moonwalk Simulations Underway (and Underwater)

    Canberra joined the global network in 1965 and operates four radio antennas. Now, preparations have begun on its fifth as NASA works to increase the network’s capacity.

    NASA’s Deep Space Network facility in Canberra, Australia celebrated its 60th anniversary on March 19 while also breaking ground on a new radio antenna. The pair of achievements are major milestones for the network, which communicates with spacecraft all over the solar system using giant dish antennas located at three complexes around the globe.

    Canberra’s newest addition, Deep Space Station 33, will be a 112-foot-wide (34-meter-wide) multifrequency beam-waveguide antenna. Buried mostly below ground, a massive concrete pedestal will house cutting-edge electronics and receivers in a climate-controlled room and provide a sturdy base for the reflector dish, which will rotate during operations on a steel platform called an alidade.

    “As we look back on 60 years of incredible accomplishments at Canberra, the groundbreaking of a new antenna is a symbol for the next 60 years of scientific discovery,” said Kevin Coggins, deputy associate administrator of NASA’s SCaN (Space Communications and Navigation) Program at NASA Headquarters in Washington. “Building cutting-edge antennas is also a symbol of how the Deep Space Network embraces new technologies to enable the exploration of a growing fleet of space missions.”

    When it goes online in 2029, the new Canberra dish will be the last of six parabolic dishes constructed under NASA’s Deep Space Network Aperture Enhancement Program, which is helping to support current and future spacecraft and the increased volume of data they provide. The network’s Madrid facility christened a new dish in 2022, and the Goldstone, California, facility is putting the finishing touches on a new antenna. 

    Canberra’s Role

    The Deep Space Network was officially founded on Dec. 24, 1963, when NASA’s early ground stations, including Goldstone, were connected to the new network control center at the agency’s Jet Propulsion Laboratory in Southern California. Called the Space Flight Operations Facility, that building remains the center through which data from the three global complexes flows.

    The Madrid facility joined in 1964, and Canberra went online in 1965, going on to help support hundreds of missions, including the Apollo Moon landings.

    Three DSN posters
    Three eye-catching posters feature the larger 230-foot (70-meter) antennas located at the three Deep Space Network complexes around the world.
    NASA/JPL-Caltech

    “Canberra has played a crucial part in tracking, communicating, and collecting data from some of the most momentous missions in space history,” said Kevin Ferguson, director of the Canberra Deep Space Communication Complex. “As the network continues to advance and grow, Canberra will continue to play a key role in supporting humanity’s exploration of the cosmos.”

    By being spaced equidistant from one another around the globe, the complexes can provide continual coverage of spacecraft, no matter where they are in the solar system as Earth rotates. There is an exception, however: Due to Canberra’s location in the Southern Hemisphere, it is the only one that can send commands to, and receive data from, Voyager 2 as it heads south almost 13 billion miles (21 billion kilometers) through interstellar space. More than 15 billion miles (24 billion kilometers) away, Voyager 1 sends its data down to the Madrid and Goldstone complexes, but it, too, can only receive commands via Canberra.

    New Technologies

    In addition to constructing more antennas like Canberra’s Deep Space Station 33, NASA is looking to the future by also experimenting with laser, or optical, communications to enable significantly more data to flow to and from Earth. The Deep Space Network currently relies on radio frequencies to communicate, but laser operates at a higher frequency, allowing more data to be transmitted.

    As part of that effort, NASA is flying the laser-based Deep Space Optical Communications experiment with the agency’s Psyche mission. Since the October 2023 launch, it has demonstrated high data rates over record-breaking distances and downlinked ultra-high definition streaming video from deep space.

    “These new technologies have the potential to boost the science and exploration returns of missions traveling throughout the solar system,” said Amy Smith, deputy project manager for the Deep Space Networkat JPL, which manages the network. “Laser and radio communications could even be combined to build hybrid antennas, or dishes that can communicate using both radio and optical frequencies at the same time. That could be a game changer for NASA.”

    Introduction

    This document contains guidelines to assist you as you prepare articles for The Earth Observer (EO) newsletter. Our Editorial Team appreciates your cooperation in keeping these guidelines in mind as you prepare articles for submission. Our team reviews every article, but following the style guidelines will expedite the editorial process.

    Please be aware that this style guide is a living document and as such continues to evolve. If it has been a while since you have submitted an article for The Earth Observer, please be sure you are using the latest version of the Style Guide. The date of the most recent update is printed in the footer of the document to make it easier to maintain the most current version of the document.

    Editing is sometimes more art than science, and while the Editorial Team will endeavor to follow the rules that follow in most cases, there may be specific cases where the Executive Editor may decide to deviate from these guidelines.

    The Earth Observer Editorial Process 

    The EO has a robust editorial team to assist with the editorial process to maintain the quality and style of the publication.

    The EO editorial staff includes:

    The editorial process is iterative. The author will typically go through two rounds of edits with the EO Editorial Team. The text is then put into a preview layout on a staging server for the author’s final review before the story is published on the EO website.

    Types of Articles in The Earth Observer

    The Earth Observer provides authors an opportunity to tell their compelling stories of Earth Science. As such it does not impose strict word count limits, but the EO has established certain general guidelines that provide a framework to follow for several types of articles.

    General article format

    Please write articles in MS Word and save as a .doc file.

    The article should begin with an introduction that provides the essentials – who, what, where, when, and why – to provide the reader with an overview of the topic to be discussed. For articles about meetings include the number of people who attended (e.g., in-person and virtual) and the objective of the meeting.

    The introduction paragraph is followed by a transition paragraph that takes the reader into the main content of the article. The article should wrap up with a conclusion.

    The suggested page length for each type of article includes inserted visual elements. In addition to the Word file, please also send separate higher resolution files for graphics, photos, animations, or visualizations. More specific requirements are available in the Guidelines for Graphics, Photos, Visualizations, Animations.

    Announcement article

    Announcement articles promote a variety of topics. Historically this type of article includes releases of new or updated Earth Science data products, information on new tools for processing and viewing data, previews of outreach activities for the Science Support Office (e.g., AGU, Earth Day), and details on upcoming science meetings or workshops (i.e., beyond the information conveyed on the NASA science calendar).

    The article is structured like a Feature article, but it is shorter, no more than two pages, including graphics and captions – see Guidelines for Graphics, Photos, Visualizations, Animations.

    Black Separator Line

    For Example: NASA Invites You to Create Landsat-Inspired Arts and Crafts, The Earth Observer, Mar–Apr 2021, 33:4, 13–14. Other examples are available on the archived issues of The Earth Observer.

    Black Separator Line

    If you have an idea for an Announcement article, please email the EO Editorial Team who will work with you on a draft. The EO Editorial Team emails are available in the section – The Earth Observer Editorial Process

    Feature article

    Feature articles cover a wide range of Earth science topics, including satellite mission launches and historic milestones, field campaign updates, data processing tool tutorials, and summaries of NASA Science Support Office outreach events. Typically, these articles span ~8–14 pages (3000–4000 words). There are cases where longer or shorter articles are acceptable.

    A photo essay format for some topics, such as outreach event summaries, offer an option to convey a significant portion of the information using a collection of photos and descriptive captions.

    Black Separator Line

    For Example: Looking Back on Looking Up: The 2024 Total Solar Eclipse

    Black Separator Line

    If you have an idea for an Feature article, please email the EO Editorial Team who will work with you on a draft. The EO Editorial Team emails are available in the section – The Earth Observer Editorial Process

    Hybrid article

    Hybrid articles combine elements of a Feature and a Summary article. Often, these articles start with a few pages of descriptive text about the subject, followed by a summary of a particular meeting. Owing to their hybrid nature, these articles tend to run a bit longer than the standard Summary article. These articles typically range between 8–12 pages (3000–5000 words.)

    If you have an idea for a Hybrid article, please email the EO Editorial Team who will work with you on a draft. The EO Editorial Team emails are available in the section – The Earth Observer Editorial Process

    In Memoriam article

    In Memoriam articles recognize individuals who have played prominent roles in NASA Earth Science. These articles tend to include biographical information about the deceased individual, a brief mention of their education, and a summary of their major career achievements – with emphasis on achievements related to NASA. A typical In Memoriam article layout includes one or more photos, including one of the person being memorialized.

    Black Separator Line

    For Example: In Memoriam: Mary Cleave [1947–2023] The In Memoriam link provides recent examples of In Memoriam articles published in The Earth Observer. Other articles are available by searching the publication’s archived issues.

    Black Separator Line

    This type of article is structured like a Feature article with the exception that the subject is referred to by their first name. In Memoriam drafts should be no more than two pages in Word – including graphics and captions – see Guidelines for Graphics, Photos, Visualizations, Animations.

    If you know someone to eulogize in The Earth Observer for their contributions to NASA Earth Science, please email the EO Editorial Team who will work with you on a draft. The EO Editorial Team emails are available in the section – The Earth Observer Editorial Process

    Kudos article

    Kudos articles acknowledges individuals or groups either within or connected to (funded by) NASA who receive significant NASA-wide awards.

    A Kudo article follows a structure similar to a Feature article. It should be a maximum of one page in Word – including a photo of person(s) or group being honored – see Guidelines for Graphics, Photos, Visualizations, Animations.

    Black Separator Line

    For Example: MOPITT Canadian Principal Investigator Receives Two Awards, The Earth Observer, Mar–Apr 2021, 33:2, 28 [bottom]. Other examples are available by searching through archived issues of The Earth Observer.

    Black Separator Line

    If you know an individual or a group of people worthy of recognition for their NASA-related achievement, please email the EO Editorial Team who will work with you on a draft submission. The EO Editorial Team emails are available in the section – The Earth Observer Editorial Process

    Summary article

    Summary articles provide an overview of recent scientific meetings and/or workshops. Ideally, a Summary article should be no more than 6 pages (~2500 words).

    Provide the flavor of the event rather than describe it in detail. Summarize the overall nature and sense of sessions. The Editorial Team has found that a mix of narrative descriptions of key (usually programmatic) presentations (e.g., plenary sessions) and summaries with less detail for the remaining (e.g., technical) presentations is optimum.

    Now that The Earth Observer is published online, it is the view of the Editorial Team format summary articles using a “minutes-style” report of the meeting. While space no longer precludes publishing such an article as it did in the past, the format does not translate well to the online communication medium. Unless a reader is really interested in the specific topic(s) discussed in the article, it is likely that they will not scroll through to the end – no matter how nice the layout looks.

    If you have an idea for a Summary article, please email the EO Editorial Team who will work with you on a draft. The EO Editorial Team emails are available in the section – The Earth Observer Editorial Process

    Guidelines for Preparing Articles for The Earth Observer

    EOis a hybrid publication, landing somewhere between a science journal and popular science magazine. Therefore, the focus should be on phenomena rather than data. The article provides an opportunity to publicize your mission, research to ~1653 subscribers (as of August 2024) around the world. Please review the content in this guideline before writing your article and reach out to the Editorial Team if you have any questions.

    Writing for the web

    The EO audience ranges from scientists to the general public. When writing an article, use plain language and active voice. When in doubt, write the article so that it would be understandable to a friend or relative not in the field.

    Black Separator Line

    For Example:

    Passive voice: The rate of evaporation is controlled by the size of an opening.

    Active voice: The size of an opening controls the rate of evaporation.

    Black Separator Line

    Avoid using jargon and technical language. When it is necessary to use technical language, please use ITALICS to offset the word in the text. Follow the italicized word with a brief definition or explanation.

    Black Separator Line

    For Example: Inference – formally derived uncertainty for area estimates of biomass, height, or other metrics – can take different forms, each of which includes specific assumptions. In this breakout session, participants considered the strengths and limitations of different inference types (e.g., intensity of computation or the ability to use different models).

    Black Separator Line

    Writing content for a website differs from print. The human eye is more inclined to read shorter paragraphs separated by breaks. It is ideal to keep sentences and paragraphs short.

    Use one space after a period. The two spaces after a period is an artifact of conventional type writers.

    Avoid editorializing in the article. For example, do not characterize a spacewalk as “daring” or “dangerous.” Describe the events factually. If things are described well, readers easily can decide for themselves whether they are daring or dangerous. Never, under any circumstances, insert any personal, political, ideological, or religious opinions or beliefs into NASA news media products.

    Catchy headline

    Write a headline that is short, searchable, and shareable. Try to keep the headline to 60 characters (including spaces). Longer headlines may be invisible to search engines.

    Unlike journal articles, The Earth Observer only includes individuals who made a significant contributions to the EO article. A typical article should only lists one or two authors. In some occasions, an article may have up to four authors. The authors should be formatted as follows:

    First Last, Organization, author email

    If there are more you wish to give credit, consider doing so in an Acknowledgment section, as discussed in the next paragraph.

    Naming files

    For consistency moving documents through the editorial process, please name the file by the file type, the topic, and the author’s last name.

    Black Separator Line

    For Example: announcement_topic_author

     feature_topic_author

     hybrid_topic_author

     memoriam_topic_author

     kudos_topic_author

     summary_topic_author

    Black Separator Line

    Use visuals to draw the reader in

    The Earth Observer is now published online. Visual elements are critical to all EO stories and are a required element to submissions. The Editorial Team would prefer having too many graphics (i.e., photos, figures, animations, and visualizations) than too few. It is helpful to insert this content into the Word file as well as include the graphics as separate files at the time of the initial submission of the draft for editorial review. See the Guidelines for Graphics, Photos, Visualizations, Animations section for more information.

    Search engine optimization

    Search Engine Optimization (SEO) is a broad set of techniques to capitalize how search engines, such as Google, scrub content on the internet. By optimizing how articles are written, it is possible to influence where content shows up in an organic, online search. The different approaches can fill an entire book. This style guide provides a few pointers to help tweak articles to optimize how the content appears in online searches.

    Headline and subheads

    A headline should be clear and compelling to reveal what the content is about as well as entice the searcher to click for more. A SEO headline is a ranking factor in search engine results. A headline can be crafted to rank higher in search results, which increases an article’s visibility and generate more clicks. This can be done by using SEO search terms — those terms that a person would type into a search box — in the headline. Shorter headlines (i.e., 60 characters including spaces) are often more effective during searches.

    Subheads provide a way to organize an article and separates the content into digestible sections. Like headlines, subheads can be optimized for SEO searches. Subheads may include key takeaways from the specific section. Keep subheads clear and concise.

    Earth Observer articles are now being posted online. Footnotes are no longer a functional option, which is a significant change for authors who have published articles in our print issues in the past. It is helpful to hyperlink words or short phrases in the article that directs the reader to additional content from the meeting, such as presentations, poster sessions, talks by attendees, programs/satellites, journal articles, etc. Relevant links should also be added to captions. See the Hyperlinks section for guidance on how to insert and format a hyperlink in the article.

    Internal links tie content in the article to other pages within an organization, such as NASA, to boost site authority. External links direct a reader to sites outside the organization. This approach also drives up site authority in SEO searches. By connecting relevant pages, it will improve article navigation and ensure users can locate relevant information.

    Alternate text for graphics

    Alternate text, or alt text, is the small description added to visual elements on the back end of a website. Search engines use the alt text to identify relevant content. Alt text also improves accessibility for all users. Tools that read webpages aloud can read alt text to help explain what visual elements contain for the visually impaired.

    Alt text should be concise, accurate, and use keywords. Keywords are highly relevant words or phrases associated with the picture and the content of the article.

    Black Separator Line

    For Example: Figure 1. Forty SWOT Early Adopter (EA) teams span the globe with a wide range of operational and applied science project topics.

    Figure credit: NASA

    Key word tag: A global map showing the locations of early adopter organizations.

    Black Separator Line

    Submitting An Outline

    An outline is not requiredprior to submitting the first draft of an article, but an outline may be beneficial for lengthy articles (i.e., features, hybrids). Outlines are particularly helpful for first-time authors or when an author is seeking guidance about the appropriateness of content for The Earth Observer. It is hard for the team to comment without seeing something in writing. More generally, submitting an outline presents an opportunity for the editorial team to provide input on the article during the writing process – as opposed to waiting until the first draft is submitted.

    Submitting Your Draft

    Do not submit a draft for review unless it is complete (i.e., contains all visual elements, captions, credits, and content). Unless you clearly indicate otherwise, the Editorial Team will assume your submission is ready for them to review. Version control problems result when text is updated after reviews have started.

    The initial draft submitted for editorial review should include graphics. including captions and credits. The editorial process is delayed when graphics, credits, and captions are added iteratively once the process has begun.

    Specific Style Guidelines

    Over more than 35 years as a NASA publication, The Earth Observer has developed its own unique style. Please review these specific guidelines detailed below, and let the Editorial Team know if you have any questions. In addition, The Earth Observer also adheres to the NASA Stylebook and Communications Manual, 9th edition (June 2020), which is closely aligned with the AP Stylebook.

    Acronyms

    Science is rife with acronyms. On first usage, always spell out the acronym and follow with the acronym in parenthesis. From that point on in the article, use the acronym. To ensure photos, figures, visualizations, and animations are understandable if removed from the larger text, please spell out acronyms in captions.

    Well-known acronyms (e.g., NASA, U.S., etc.) do not need to be spelled out. Separate the acronym for United States (e.g., U.S.) and United Kingdom (e.g., U.K.) with periods.

    Black Separator Line

    For Example: Level-1 (L1), Global Ecosystem Dynamics Investigation (GEDI), International Space Station (ISS), Precision Orbit Determination (POD), etc.

    Black Separator Line

    Only capitalize proper nouns as defined by the dictionary or AP style. The Earth Observer style does capitalize the first letter of a specific product that will be turned into an acronym.

    Black Separator Line

    For Example: Do not capitalize the first letter of each word in “solid rocket booster (SBR),” even though the subsequent use of the acronym SRB will appear in the article.

    Black Separator Line

    A compound acronym arises when parentheses occur inside of parentheses. In this situation, use [BRACKETS] for the outer set of parentheses and (PARENTHESES) for those inside.

    Black Separator Line

    For Example: Thomas Neumann [GSFC—Deputy Director of GSFC’s Earth Sciences Division (ESD)] welcomed meeting participants on behalf of the ESD.

    Black Separator Line

    Affiliations

    Use a possessive for an organization when it is part of NASA. Do not use a possessive when using the agency as an adjective.

    Black Separator Line

    For Example: NASA’s Goddard Space Flight Center (GSFC); subsequent references would just use “GSFC.”

    Black Separator Line

    For Example: SWOT data products available through PO.DAAC provides centralized, searchable access that is available using an in-cloud commercial web service through the NASA EarthData portal.

    Black Separator Line

    Write out an organization that is not part of NASA.

    Black Separator Line

    For Example: Gustavo Oliveira [Clark University] presented details on the project “Irrigation as Climate-Change Adaptation in the Cerrado Biome of Brazil.”

    Black Separator Line

    When multiple “levels” of affiliation are listed, start with the “top-level” affiliation as a possessive followed by lower level. If the affiliations are mentioned again later in the article, only the acronym for the lowest level needs to be repeated.

    Black Separator Line

    For Example: For NASA’s Goddard Space Flight Center’s Global Modeling and Assimilation Office (GMAO), subsequent references to this entity would be “GMAO.”

    Black Separator Line

    For Example: For University of Maryland, Baltimore County’s Earth System Science Interdisciplinary Center (ESSIC), subsequent references to this entity would be “ESSIC.”

    Black Separator Line

    When a person is affiliated with two (or more) distinct entities, separate the two entities by slashes.

    Black Separator Line

    For Example: Project Scientist Felix Landerer (NASA/JPL), followed by detailed assessments of the G-FO mission and operations status from the core SDS centers and flight operations teams.

    Black Separator Line

    When a NASA Center and contractor are listed, please list the NASA Center followed by contractor and separate the two entities by a slash.

    Black Separator Line

    For Example: NASA’s Goddard Space Flight Center (GSFC)/Global Science & Technology, Inc. (GST).

    Black Separator Line

    Capitalize Earth, Moon, Sun

    NASA capitalizes the first letter in Earth, Moon, and Sun.In addition, do not use the modified ‘the’ before Earth.

    Black Separator Line

    For Example: This strategy acknowledges the urgency of global changes, such as accelerating environmental shifts, understanding Earth’s interconnected systems, and developing scalable information.

    Black Separator Line

    Chemical formulas

    Chemical formulas should be treated like acronyms. Spell out a chemical formula upon first use in an article followed by the chemical formula in parenthesis. Use appropriate subscripts and superscripts in the chemical formula. From that point onward, use the chemical formula in the article.

    Black Separator Line

    For Example: The data show that global and East Asian emissions of oxides of nitrogen (NOx) have decreased since 2010, contrasting India and Southeast Asia’s rising trends. In Southeast Asia, NOx and sulfur dioxide (SO2) emissions increased from 1990–2018, while black carbon (BC) emissions peaked in 2007.

    Black Separator Line

    Compound words

    Make one word out of all compound words (e.g., multipurpose, multiangle).

    Exception: Hyphenate cases where the same vowel repeats (e.g., bio-optical, multi-imager).

    Cross-references

    It is common to reference a previous EO article to provide context and background for the current story. The Editorial Staff recommends authors cross-reference prior EOarticle. The title of the article, volume, issue, and page range in parenthesis. The information should be italicized, except for “The Earth Observer,” which should be plain text.

    The name of the cross-referenced article should be hyperlinked to that article. You can find past Earth Observer newsletters on the archive page.

    Black Separator Line

    For Example: ESIP was created in response to a National Research Council (NRC) review of the Earth Observing System Data and Information System (EOSDIS). (To learn more about EOSDIS, see Earth Science Data Operations: Acquiring, Distributing, and Delivering NASA Data for the Benefit of Society, in the March–April 2017 issue of The Earth Observer [Volume 29Issue 2, pp. 4–18].) As NASA’s first Earth Observing System (EOS) missions were launching or preparing to launch, the NRC called on NASA to develop a new, distributed structure that would be operated and managed by the Earth science community and would include observation and research, application, and education data.

    Black Separator Line

    Dates, months, and seasons

    When referencing a date, spell out the month, followed by the day (if included) and year. This style differs from AP. A comma always follows a year if the date is written in-line of the sentence.

    Black Separator Line

    For Example: January 27, 2022; January 2022

    For Example: PACE launched on February 8, 2024, from Vandenberg Space Force Base in California.

    Black Separator Line

    Capitalize a season followed by a year, but not when just referring to a season.

    Black Separator Line

    For Example: Spring 2022; summer

    Black Separator Line

    Spell out time zones, such as Eastern Daylight Time, and thereafter replace with the acronym (i.e., EDT).

    Black Separator Line

    For Example: In Cleveland, the eclipse began at 1:59 PM. Eastern Daylight Time (EDT), with totality spanning 3:13–3:17 PM.

    Black Separator Line

    Directions and regions

    EO articles follow AP style for directions (e.g., north, south, east, west, northeast, southwest, norther, western, southern, eastern). The directions should be lowercase when indicating a compass direction and when it is used to describe sections of states or cities.

    Black Separator Line

    For Example: The cold front is moving east.

    Black Separator Line

    The direction should be capitalized for a proper name or large regions. 

    Black Separator Line

    For Example: NASA’s South/Southeast Asia Research Initiative (SARI) is a regional initiative under the LCLUC program that addresses the critical needs of the South/Southeast Asia region.

    For Example: West Virginia or North Dakota

    Footnotes

    The Earth Observer has transitioned to an online publication. Footnotes will no longer be used in articles. Instead of footnotes, the publication will use hyperlinks to direct readers to additional content. Refer to the section on Hyperlinks for more information on how to include a hyperlink in an article. A good mantra to follow – if you are unsure if a reference is needed, leave it out.

    Formal titles

    Formal titles, such as Ms. or Dr., are used in articles that are more personal, such as Kudos, In Memoriam, and The Editor’s Corner. For all other articles, the professional title is not used. When you introduce a person in the story, present the name in BOLD followed by their agency and position in ITALICS, offset by brackets.

    Black Separator Line

    For Example: First Last [Agency—Job Title] began by providing an update on the status of the new launch date for the. . . .

    Black Separator Line

    After the individual is introduced in the article, EO style follows a particular style for using the name again. If the individual’s name is included in the same paragraph where the person was introduced, only use the last name [UNBOLD]. If the individual is mentioned later in the article, several paragraphs removed from introduction, use the full name [FIRST LAST, UNBOLD].

    Prior to moving online, The Earth Observer used footnotes to reference information in an article. The online publication will now use hyperlinks to refer the reader to additional content on a topic. As a general rule, hyperlink content regarding missions, instruments, field campaigns, models, papers, and other programs named in the article. It is not necessary to link to each individual institution mentioned when individuals are identified in summaries.

    The first step in this process is to identify the anchor text to highlight in the sentence. The anchor text includes a word or phrase that points the reader to additional content.

    Black Separator Line

    For Example: Anchor text: Volume 35 Issue 6 of The Earth Observer

    Black Separator Line

    Find the Uniform Resource Locator (URL) for the webpage. The URL is an address that specifies the location of a resource on the internet.

    Black Separator Line

    For Example: URL: https://eospso.gsfc.nasa.gov/sites/default/files/eo_pdfs/EO%20Nov-Dec%202023-Digital%20508.pdf

    Black Separator Line

    Note: When inserting a link to a prior published article from The Earth Observer’s archive, be certain to capture the URL for the first page of the referenced article, as opposed to the issue’s first page.

    To insert a hyperlink, copy the URL from the website where the additional content can be found. Select the word or phrase to use as anchor text. Do not include an acronym as part of the anchor text for a hyperlink. Select the hyperlink command under the Insert dropdown menu. Paste the URL into the link box. Be sure the ‘Web Page or File’ tab is selected (not the Email tab). The hyperlinked text will appear blue and underlined.

    Black Separator Line

    For Example: It is possible to find this information in Volume 35 Issue 6 of The Earth Observer.

    For Example: The Hyperwall presentation highlighted recent discoveries from the James Webb Space Telescope (JWST) mission.

    Black Separator Line

    Hyphens, en dashes, and em dashes—oh my!!

    Hyphen: – A hyphen is used to separate compound adjectives or words.

    Black Separator Line

    For Example: The satellite reached a near-Earth orbit.

    Black Separator Line

    En Dash: – An en dash spans the length of a typed lowercase ‘n.’ This special character is used to separate numbers.

    Black Separator Line

    For Example: The meeting was held March 5–8 in Denver, CO. [Note there is no space between the numbers in this example.]

    Black Separator Line

    The Earth Observer style follows the NASA style guide that uses an en dash to insert a pause in the sentence. The en dash is set apart by a space on either side. In this instance, the en dash is used instead of an em dash.

    Black Separator Line

    For Example: The passport identified six hidden images – all six posters from the Science Explorers Poster Series– strategically placed within the exhibit’s perimeter.

    Black Separator Line

    You can insert an en dash in Word on a Mac by typing the “Option” and “hyphen/dash” keys simultaneously.

    You can also insert an en dash in Word using the Insert tab and select Advanced Symbols. A box will open with a variety of characters. Select “Garamond” from the Font pulldown menu (Garamond is the newsletter’s preferred font), then select the – symbol (or “en dash”) from the array of options displayed. You will then see a confirmation of your selection appear below the symbol options (i.e., “Insert [Garamond] character 150 (Unicode character 2013).” Please note: the character number (150 in the case of Garamond) could be different. For example, an en dash in Palatino font is character 208.

    en-dash graphic

    Em Dash: — An em dash spans the length of a typed lowercase ‘m.’ This special character is used when separating the organization and the job title when introducing a person in the article. In other styles, the em dash is used as a pause in a sentence. Following NASA style guidelines, the pause is provided by the en dash.

    Black Separator Line

    For Example: Thomas Neumann [GSFC—Deputy Director of GSFC’s Earth Sciences Division (ESD)] welcomed meeting participants on behalf of the ESD.

    Black Separator Line

    You can insert an em dash in Word by going to the Insert tab and selecting Advanced Symbols. A box will open with a variety of characters. Select character 151. For more detailed guidance, please refer to the section above regarding how to insert an en dash.

    em-dash graphic

    Italics and quotes

    Place Latin phrases in ITALICS (e.g., in situ, a priori, ad hoc, ex officio) on every appearance in the article. Do not italicize abbreviated Latin phrases (e.g., i.e., a.k.a., et al.). Use the Latin phrase i.e., instead of ‘such as’ and e.g., instead of ‘that is to say.’

    Black Separator Line

    For Example: The Afternoon Satellite Constellation, a.k.a., the“A-Train,” can see Earth in a whole new dimension.

    For Example: Guy Schumann [Water in Sight]explained this Swedish start-up company uses SWOT data to validate in situ gauge data in Malawi.

    Black Separator Line

    Place technical language in the text in ITALICS followed by a definition. Only use the italics on the first usage of the word.

    Black Separator Line

    For Example:There were several large polynyas – areas of open ice where sea ice would be expected – detected.

    Black Separator Line

    Items in a series

    The Earth Observer deviates from AP style in the use of commas in a list or series. Use the Oxford comma in a series of items.

    Black Separator Line

    For Example: The sensor measures at three different wavelengths corresponding to blue, green, red, and infrared light.

    Black Separator Line

    In more complex series where one of the items is a series of items within a series, it is permissible to use semi-colons to separate the series (see below).

    Black Separator Line

    For Example: The blue, green, and red channels; the two-infrared channels; and ultraviolet channel were all impacted.

    Black Separator Line

    Numbers

    In the article, spell out zero to nine. Use numerals for any number greater than or equal to 10. If a sentence contains several numbers, excluding a year, that are both greater than and less than 10, use the numerals for all numbers.

    Black Separator Line

    For Example: Improving the data calibrations of the acceler­ometer measurements – which are noise contaminated on one of the two G-FO spacecraft – remains a core focus of the project SDS team.

    For Example: The NASA Hyperwall served as the backdrop for 57 Hyperwall Storiesat the meeting, including 8 presentations delivered by the 2023 winnersof the AGU Michael Freilich Student Visualization Competition.

    For Example: Following the project team’s status presentations, there was a 30-minute session to answer questions from the science community and discuss in more detail the mission performance, near-term operations and data processing plans, as well as to gather suggestions and feedback from the community.

    Black Separator Line

    Ordinal numbers

    Ordinal numbers are words representing position or rank in sequential order. The EO follows AP rules in how to present ordinal numbers in an article. Spell out one through nine and use figures for 10 and above. This rule holds for article headlines and subheads.

    Black Separator Line

    For Example: AEOIP Holds Third Annual Workshop

    For Example: As GPM is now well into its 10th year in orbit, the time is fitting to reflect on and celebrate what this mission has accomplished and showcase its contributions to science and society.

    Black Separator Line

    References

    The Earth Observer is not a peer-reviewed journal and typically does not include a list of references. It is helpful to hyperlink key words/phrases to other resources, such as journal articles. See Hyperlinks section to learn how to insert and format this text.

    In rare instances when a formal reference is required (e.g., referencing a Figure that originally appeared in another journal article), please use theAmerican Meteorological Society format.

    References to teams

    In a story, spell out “Science Team (ST)” in the first instance and use the team acronym from that point forward in the story.

    Black Separator Line

    For Example: The Precipitation Measurement Mission (PMM) Science Team (ST) includes more than 20 international partners.

    Black Separator Line

    For other named teams, use the initial caps for the team name and then use “Team” as shorthand afterwards (e.g., “Informatics Team” first time, then abbreviate as “Team” subsequently).

    Do not capitalize generic references to a team (e.g., a team of experts).

    State abbreviations

    The Earth Observer differs from AP style in how it presents state abbreviations. This publication uses the two-letter postal code for state abbreviations.

    Black Separator Line

    For Example: The meeting was held March 5–8 in Denver, CO.

    Black Separator Line

    Typographical emphasis

    Please do not use specialized typographic formatting (e.g., Heading 1, Heading 2, etc.). Instead, please use internal formatting (e.g., BOLD and ITALIC) as directed in the style guide (e.g., headings, subheads, author/speaker names, etc.). If you do use the specialized typographic formatting, it affects the insertion and layout of text on the EO website, which takes time to correct and slows publication.

    When inserting a table, do not use framed or shaded boxes.

    Units

    Do not spell out units. Use the standard abbreviation. Include both English and metric units in the text. One exception is The Editor’s Corner column, which does not use both the English and metric units.

    Black Separator Line

    For Example: The data collected from G/G-FO has a native resolution of about 300 km (~186 mi).

    Black Separator Line

    Guidelines for Graphics, Photos, Visualizations, Animations

    The EO supports several visual options to enhance the text of an article. A figure refers to a visual display of data. An photo refers to a photograph. An animation is a series of images or model results that illustrate a concept. A visualization is a video of content.

    To maintain a consistent design for The Earth Observer, please insert the graphic, photo, animation, or visualization in the appropriate location in the Word document. Along with the Word document, please submit the photo, graphic, visualization, or animation as separate files.

    Inserting figures, photos, animations, and visualizations

    Upon first usage in the text, include the correct graphic descriptor (i.e., figure, photo, animation, or visualization) and appropriate number in the text in bold. Restart numbering for each visual element type (e.g., Figure 1, Photo 1, Figure 2, Figure 3, Photo 2, Visualization 1).

    Black Separator Line

    For Example: The GMI is a 13-channel conically scanning PMW radiometer providing observations across a wide swath (885 km or ~550 mi) to estimate precipitation – see Figure 1.

    Black Separator Line

    The EO editorial staff ask that no additional formatting be used when inserting these files into the Word document. At the location in the text where the photo, figure, animation, or visualization should appear in the story, advance the text by two lines. Place the cursor in the first blank line. Go to the insert tab and select the picture icon. Select ‘Picture from File’ from the dropdown. Navigate to the location on your computer where the file is located and select ‘Insert.’

    image insert graphic

    Caption, credit, and tags

    After inserting the figure, photo, visualization, or animation, provide a caption and credit. It is important to think of the caption and credit as stand-alone items in the story.

    The graphic may need to be revised to accommodate EO style. Remove indicators, ‘a’, b’, etc from panels or items of note. EO style requires that different panels or points of interest in the graph should use “pointers,” such as top, middle, bottom.

    The caption should be descriptive and not overly technical. It should convey the content in image/figure without relying too heavily on the surrounding text to add context. Relevant links should also be added to captions. Spell out all acronyms, whether for equipment or institutions, are already spelled out in the text, because the image can be lifted from the article and used without the article where it originated. The pointer in the caption should be enclosed in brackets and the text ITALICIZED (e.g., [left]).

    The credit line should include the name of the institution or individual who should be credited for the image/figure/photograph. If an institution is listed, write the name [NO ITALICS]. Ifan individual is listed, include their institution in brackets. If the credit refers to a journal article, please use a reference to the journal (e.g., Williams et al. 2024) and link the credit reference to the DOI for the journal article. Note: there is no period after the credit line.

    Graphic/photo requirements

    • Photos and graphics should be at least 1440 pixels wide. If the photo is small or low resolution, padding will be added to each side to fit the dimensions for the website.
    • Provide high-resolution graphics source files of all graphics. Submit graphics and photos as a .gif, .tif, or .eps file.
    • Do not resize photos or graphics.
    • Submit raw data in plain text for tables. The Editorial Team will reconfigure the content into tables to insert on the EO website.

    Final Thoughts

    There are many style topics not specified here. As stated earlier, the NASA Stylebook and Communications Manual and AP Style Guide (in that order) should be followed when something is not explicitly described in this guide.

    In addition, previous articles from The Earth Observer (particularly those from recent years) can serve as templates for future articles. It is a good idea when preparing to submit an article to look at some previous articles available in The Earth Observer archive.
