    Name: Joshua Abel

    Title: Lead systems engineer for the Roman Space Optical Telescope Assembly

    Formal Job Classification: Flight Systems Design Engineer

    Organization: Instrument/Payload Systems Engineering Branch (Code 592), Mission Engineering and Systems Analysis Division, Engineering and Technology Directorate

    Editor’s note: The Nancy Grace Roman Space Telescope’s Optical Telescope Assembly (OTA) includes the telescope’s primary and secondary mirrors, as well as supporting optics. The OTA enables the telescope to collect light that is then delivered to the observatory instruments.

    What do you do and what is most interesting about your role here at Goddard? How do you help support Goddard’s mission?

    As the lead systems engineer for the Roman Space Telescope Optical Telescope Assembly, I am the government technical authority for procurement of the assembly, currently being manufactured by L3Harris Corporation in Rochester, New York. I am responsible for technical oversight of the vendor and verifying requirements.

    What was your path to becoming an aerospace engineer at Goddard?

    In 1999, I received a B.S. in interdisciplinary engineering focused on biomedical engineering from Purdue University. I began a master’s in biomedical engineering in bioheat transfer from Purdue University, but left in 2001 to work at Space Systems/Loral as a thermal systems engineer for satellites.

    In 2005, I came to Goddard to work on Hubble Servicing Mission 4 and other NASA satellite servicing projects as a thermal systems engineer. In 2018, I began supporting the New Opportunities Office as a systems engineer, later joining the Instrument/Payload Systems Engineering Branch in my current role.

    What are your goals as the lead systems engineer for the Roman Space Telescope Optical Telescope Assembly?

    My goal is to deliver the assembly to the Roman observatory on time, within budget, and meeting all the technical requirements. I lead a small team of subject matter experts to review the vendor’s plans and help resolve any technical issues.

    What is your management style?

    I have a broad engineering background which helps me ask the right questions. I like to build consensus within the team and consolidate everyone’s work into a cohesive and understandable package, communicating complex issues both within the team and to management.

    What makes Goddard special?

    Everyone here loves their work and is focused on mission success. Even when conversations are difficult and the stakes are high, the emotion comes from caring so deeply. As a systems engineer, my goal is to listen to all ideas and help find the best direction for the project.

    What drives you?

    I try to do what is needed and contribute to the best of my ability. I am energized when someone says they need help, be it fixing things that are broken or putting new things together. I’m always excited to continue to learn from the our expert team members and vendors.

    I prefer working in a team. I like the dynamic environment of systems engineering, which is full of difficult problems that need a larger group to get enough perspectives to solve.

    My background and skill mix are a little bit of everything. I enjoy English, communication, math, and science. These interests help me see different sides of a problem.

    I like to take things that are slow and repetitive and make them faster and more interesting for myself and others. For example, I like to write Microsoft Excel programs to analyze thermal model data and other large databases to improve productivity. 

    What advice would you give young engineers?

    Take whatever project you are working on and exceed expectations. Don’t be afraid to ask questions. Early tasks for young engineers are not always the most exciting, but work to the best of your ability and try to learn as much as you can. Understand the job and try to see if it can be accomplished better or faster. If you approach every task with this attitude, the next opportunity will always come.

    Build your network of experts and use their lessons learned to help your project, always returning that help when you can. Oftentimes the most important piece of knowledge you’ll be able to provide your team is simply knowing who to call to for advice. All of NASA’s engineers are always willing to help.

    What are your hobbies?

    I play and coach soccer and I also play guitar with my three children around our fire pit. Like every engineer, I’m continually working on home improvement projects for my favorite manager, my wife, who is a thermal systems engineer at the Johns Hopkins Applied Physics Laboratory in Laurel, Maryland.

    Rocket Exhaust on the Moon: NASA Supercomputers Reveal Surface Effects


    Researchers at NASA’s Marshall Space Flight Center in Huntsville, Alabama produced a simulation of the Apollo 12 lander engine plumes interacting with the lunar surface. This animation depicts the last half-minute of descent before engine cut-off, showing the predicted forces exerted by plumes on a flat computational surface. Known as shear stress, this is the amount of lateral, or sideways, force applied over a set area, and it is the leading cause of erosion as fluids flow across a surface. Here, the fluctuating radial patterns show the intensity of predicted shear stress. Lower shear stress is dark purple, and higher shear stress is yellow.

    Through Artemis, NASA plans to explore more of the Moon than ever before with human and robotic missions on the lunar surface. Because future landers will be larger and equipped with more powerful engines than the Apollo landers, mission risks associated with their operation during landing and liftoff is significantly greater. With the agency’s goal to establish a sustained human presence on the Moon, mission planners must understand how future landers interact with the lunar surface as they touch down in unexplored moonscapes.

    Landing on the Moon is tricky. When missions fly crew and payloads to the lunar surface, spacecraft control their descent by firing rocket engines to counteract the Moon’s gravitational pull. This happens in an extreme environment that’s hard to replicate and test on Earth, namely, a combination of low gravity, no atmosphere, and the unique properties of lunar regolith – the layer of fine, loose dust and rock on the Moon’s surface.

    Each time a spacecraft lands or lifts off, its engines blast supersonic plumes of hot gas toward the surface and the intense forces kick up dust and eject rocks or other debris at high speeds. This can cause hazards like visual obstructions and dust clouds that can interfere with navigation and science instrumentation ­or cause damage to the lander and other nearby hardware and structures. Additionally, the plumes can erode the surface under the lander. Although craters were not formed for Apollo-scale landers, it is unknown how much the larger landers being planned for upcoming Artemis missions will erode the surface and whether they will rapidly cause cratering in the landing zone, posing a risk to the lander’s stability and astronauts aboard. 

    To improve its understanding of plume-surface interactions (PSI), researchers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, have developed new software tools to predict PSI environments for NASA projects and missions, including the Human Landing SystemCommercial Lunar Payload Services initiative, and future Mars landers. These tools are already being used to predict cratering and visual obscuration on upcoming lunar missions and are helping NASA minimize risks to spacecraft and crew during future landed missions.

    The team at NASA Marshall recently produced a simulation of the Apollo 12 lander engine plumes interacting with the surface and the predicted erosion that closely matched what happened during landing. This animation depicts the last half-minute of descent before engine cut-off, showing the predicted forces exerted by plumes on a flat computational surface. Known as shear stress, this is the amount of lateral, or sideways, force applied over a set area, and it is the leading cause of erosion as fluids flow across a surface. Here, the fluctuating radial patterns show the intensity of predicted shear stress. Lower shear stress is dark purple, and higher shear stress is yellow. 

    These simulations were run on the Pleaides supercomputer at the NASA Advanced Supercomputing facility at NASA’s Ames Research Center in California’s Silicon Valley over several weeks of runtime, generating terabytes of data. 

    NASA is showcasing 42 of the agency’s computational achievements at SC23, the international supercomputing conference, Nov. 12-17, 2023, in Denver, Colorado. For more technical information, visit: 

    https://www.nas.nasa.gov/sc23.

    Used for this research, the framework for the Descent Interpolated Gas Granular Erosion Model (DIGGEM) was funded through NASA’s Small Business Innovation Research program within NASA’s Space Technology Mission Directorate (STMD) in Washington, and by the Stereo Cameras for Lunar Plume Surface Studiesproject that is managed by NASA’s Langley Research Center Hampton, Virginia also funded by STMD. The Loci/CHEM+DIGGEM code was further refined through direct support for flight projects within the Human Landing System program funded by NASA’s Exploration Systems Development Mission Directorate (ESDMD) in Washington as well as the Strategy and Architecture Office in ESDMD.

    Gator Speaks

    Thank you very much!

    You may be thinking, ‘Why is Gator telling me thanks?’

    The month of November naturally brings a sense of gratitude with it, and I feel the joy by merely expressing thankfulness to others, so I wanted to thank you for reading this month’s portion of Gator Speaks.

    Whether surrounded by the love and laughter of cherished family or the comforts of a shared experience with valued friends, November warms the heart like indulging in a fresh slice of pumpkin pie (something else to be thankful for!).

    Just like it is easy to eat a slice or three of pumpkin pie, it is easy to find reasons to be thankful at NASA Stennis.

    Nov. 11 was Veterans Day. There are many NASA employees at NASA Stennis who have served in various military branches and are now contributing their talents as part of our skilled and diverse workforce. One such veteran working at NASA Stennis is featured this month.

    In addition to Veterans Day on Nov. 11, the Stennis Day in the Bay event highlighted how thankful NASA Stennis is for the great community support and relationships NASA Stennis enjoys. We are all better together!

    Nov. 14 is the 90th birthday for the great, NASA astronaut Fred Haise. His name graces the test stand where RS-25 engine testing is underway for future Artemis missions. Haise also is a veteran, as the Korean War put him on a path to joining the military and ultimately becoming a NASA astronaut. Read how that came to pass here.

    Nov. 23 is Thanksgiving. How can one not be thankful for the benefits NASA provides to humanity? From exploring the Moon and Mars, to increasing access to space for all, to growing new commercial markets, space exploration helps us gain a new perspective.

    And just like exploring space helps us gain a new perspective, so, too, does taking inventory of all we have to be thankful for throughout the month of November.

    NASA Stennis Employee named NASA Energy Action Hero

    Damon Saul
    Energy Action Spotlight: Damon Saul
    NASA

    Damon Saul, lead operator of NASA’s Stennis Space Center’s Energy Management Control System, was honored as a NASA energy action hero in October.

    Each October, the federal government celebrates Energy Action Month to honor the work of the federal workforce to achieve mission success while also cutting energy waste, reducing costs, optimizing performance, and advancing America’s progress toward energy independence, resilience, and security.

    NASA has made significant strides in its Energy and Water Management Program, including

    • Reducing total energy consumption by 19% and greenhouse gas emissions 47% since FY 2008
    • Increasing our consumption of carbon pollution-free electricity to 41% of total electricity
    • Reducing facility water intensity by 33% since FY 2007

    None of this would be possible without the efforts of hundreds of NASA personnel, many of whom are never recognized for their contributions. Since 2021, NASA has recognized some of the unsung heroes through the Energy Action Spotlights.

    Former NASA Astronaut Haise Turns 90

    Former NASA astronaut and Biloxi, Mississippi native, Fred Haise, celebrated his 90th birthday – and lifetime of accomplishments – on Nov. 14.

    Haise initially pursued a career in journalism before serving in the Korean War as a Marine Corps fighter pilot. After the war, he flew as a research pilot. One of 19 individuals selected by NASA as an astronaut candidate in April 1966, Haise was the highest-scoring applicant of Astronaut Group 5.

    Following training, Haise served as a backup crew member for the Apollo 8 and Apollo 11 missions to the Moon before his chance to fly in space came on the Apollo 13 mission as lunar module pilot with commander Jim Lovell and command module pilot Jack Swigert. He was slated to become the sixth person to walk on the lunar surface.

    However, Haise never had his chance to step onto the Moon. Just 56 hours into the Apollo 13 mission, an oxygen tank explosion created a crisis that held the world spellbound for days. Haise was in the lunar module at the time of the incident; by the time he reached his command module seat, oxygen tank No. 2 was gone.

    The world watched as the crew endured a perilous trip around the Moon and back to Earth in the crippled spacecraft. The mission is well documented in print and onscreen. In total, Haise logged 142 hours and 54 minutes in space on the Apollo 13 mission.

    The Mississippi native remained a NASA astronaut for nine more years and was slated to serve as commander of the Apollo 19 mission to the Moon before it was canceled by the end of the Apollo Program. Haise was inducted into the Astronaut Hall of Fame in 1997. Twelve years later, NASA presented him with the agency’s Ambassador of Exploration Award in recognition of his role as a spokesperson for space.

    Haise presented the encased Moon rock he received for the recognition to his former Biloxi elementary school – Goren Elementary – for display to students. Since then, he has remained a space spokesperson and a staunch supporter of NASA’s Stennis Space Center and INFINITY Science Center.

    “I think aviation, space, and science museums are important for the knowledge imparted to young and old,” he said of the Mississippi science facility that serves as the official visitor center of NASA Stennis. “For the young, it is possible the interesting things they see and learn about will inspire them to make the most of the talent with which they are blessed. INFINITY also serves as a beacon along the highway into Mississippi to encourage people to visit and stay awhile. It gives them a view of the incredible work being done at Stennis Space Center. Through the hands-on exhibits and special programs, education is provided to many visiting young people.”

    Happy birthday to Mississippi’s own Fred Haise!

  • How NASA’s Roman Space Telescope Will Chronicle the Active Cosmos

    A light blue outline of 18 squares arranged in three rows of six that are slightly arched downward like a rainbow appears near the top left on a black background. Six more appear in a column directly beneath it, and then two more rows that are slightly taller appear to the right, and finally one more row the same length as the first one appears to the right of that. Then this whole grouping of blue squares is slightly rotated and stamped many times. The final product looks like a flower-like mandala or an intricate snowflake.
    This animation shows a possible layout of NASA’s Nancy Grace Roman Space Telescope’s High Latitude Time-Domain Survey tiling pattern. The observing program will be designed by a community process, but it is expected to cover five square degrees – a region of the sky as large as 25 full moons – and pierce far into space, back to when the universe was about 500 million years old, less than 4 percent of its current age of 13.8 billion years.

    NASA’s Nancy Grace Roman Space Telescope will pair space-based observations with a broad field of view to unveil the dynamic cosmos in ways that have never been possible before.

    “Roman will work in tandem with NASA observatories such as the James Webb Space Telescope and Chandra X-ray Observatory, which are designed to zoom in on rare transient objects once they’ve been identified, but seldom if ever discover them,” said Julie McEnery, Roman’s senior project scientist at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “Roman’s much larger field of view will reveal many such objects that were previously unknown. And since we’ve never had an observatory like this scanning the cosmos before, we could even find entirely new classes of objects and events.”

    The mission’s High Latitude Time-Domain Survey is well-designed to discover a particular type of exploding star that astronomers can use to trace the evolution of the universe and probe possible explanations for its accelerated expansion. And since this survey will repeatedly observe the same large vista of space, scientists will also see sporadic events like stellar corpses colliding and stars being swept into black holes.

    The survey will look beyond our galaxy to observe the same patch of sky approximately every five days for two years. Stitching these observations together like stop-motion animation will create movies that will reveal a wealth of transient events.

    NASA’s upcoming Nancy Grace Roman Space Telescope will see thousands of exploding stars called supernovae across vast stretches of time and space. One kind, called type Ia, serves as “standard candles” because they peak at about the same intrinsic brightness. Scientists can use them to measure distances and trace cosmic expansion over time, providing a window onto the universe’s distant past. Credit: NASA’s Goddard Space Flight Center/CI Lab

    Retreating Stellar Sparks

    Astronomers will hunt through all this data for a special kind of exploding star called type Ia supernovae. These phenomena originate from certain binary star systems that contain at least one white dwarf – the small, hot core remnant of a Sun-like star. In some cases, the dwarf may siphon material from its companion. This triggers a runaway nuclear reaction that ultimately detonates the thief. Astronomers have also found evidence supporting another scenario, involving two white dwarfs that spiral toward each other until they merge. If their combined mass is high enough, they, too, may produce a type Ia supernova.

    Since these explosions each peak at a similar, known intrinsic brightness, astronomers can use them to determine how far away they are by simply measuring how bright they appear. Astronomers will use Roman to study the spectrum of light from these supernovae to find out how rapidly they appear to be moving away from us due to the expansion of space.

    By comparing how fast type Ia supernovae at different distances are receding, scientists will trace cosmic expansion over time. This will help us understand whether and how dark energy – the unexplained pressure thought to be speeding up the universe’s expansion – has changed throughout time. Using these and other Roman measurements should also help clear up mismatched measurements of the Hubble constant, which is the universe’s current expansion rate.

    “Roman will paint a more vivid picture of our universe’s past and present, giving us new clues about its possible fate,” said Rebekah Hounsell, a research scientist at the University of Maryland, Baltimore County and Goddard, who is exploring ways to optimize Roman’s High Latitude Time-Domain Survey. “Its findings could reshape our understanding of the cosmos.”

    This time-lapse of supernova 2018gv in galaxy NGC 2525 compresses nearly one-year of observations from NASA’s Hubble Space Telescope into a few seconds. The supernova initially outshines the brightest stars in the galaxy before fading into obscurity. NASA’s Nancy Grace Roman Space Telescope, currently under construction, could capture such events from start to finish and alert other telescopes, such as the Hubble and James Webb space telescopes, for even more detailed observations.

    Fleeting Cosmic Wonders

    Because of the way this survey will observe the cosmos, it will also spot other rare phenomena. Through Roman, we will witness the birth of new black holes that form when neutron stars – the cores of exploded stars that weren’t quite massive enough to collapse to form black holes on their own – merge. These titanic events create ripples in the fabric of space-time and brilliant kilonova explosions.

    The mission is also expected to reveal several dozen tidal disruption events, which happen when a star venturing too close to a black hole is shredded by the black hole’s extreme gravity. The stellar shrapnel generates a huge amount of light as it speeds toward the black hole. Roman will pick up these flares of energy to learn how black holes affect their surroundings.

    The survey will also allow astronomers to explore variable objects, like active galaxies whose cores each host an extremely bright quasar. A quasar is a brilliant beacon of intense light powered by a supermassive black hole. The black hole voraciously feeds on infalling matter that unleashes a torrent of radiation. Roman’s steady gaze will help astronomers study how and why these outbursts fluctuate in brightness.

    And by finding hundreds of faint, faraway quasars, Roman will also allow scientists to probe the period of reionization. During this cosmic epoch, scientists think intense ultraviolet light from quasars stripped electrons from atoms and turned them into ions. This transition ushered in “cosmic dawn,” as the universe went from being mostly opaque to transparent, allowing visible and ultraviolet light to travel freely.

    “This Roman survey will provide a treasure trove of data for astronomers to comb through, enabling more open-ended cosmic exploration than is typically possible,” McEnery said. “We may serendipitously discover entirely new things we don’t yet know to look for.”

    The Nancy Grace Roman Space Telescope is managed at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, with participation by NASA’s Jet Propulsion Laboratory and Caltech/IPAC in Southern California, the Space Telescope Science Institute in Baltimore, and a science team comprising scientists from various research institutions. The primary industrial partners are Ball Aerospace and Technologies Corporation in Boulder, Colorado; L3Harris Technologies in Melbourne, Florida; and Teledyne Scientific & Imaging in Thousand Oaks, California.

  • Five Ways NASA Supercomputing Takes Missions from Concept to Reality

    NASA high-end computing plays a key role in taking many agency missions from concept to application in the real world. From increasing accuracy of global weather forecasts for forecast entities (like NOAA) to warn of severe storms, to designs for future air taxis to safely fly people around urban areas, to parachute design tests for landing spacecraft on the Moon and other planets, our supercomputing resources and experts are driving science and engineering advances for the benefit of humanity.

    These projects and much more will be on display in the agency’s hybrid exhibit during SC23, the International Conference for High Performance Computing, Networking, Storage and Analysis. This year’s conference is being held in Denver, Nov. 12–17.

    1. Simulating Air Taxi Safety Near the Ground

    With the development of urban air mobility (UAM) vehicles, in the near future people might be hailing rides in air taxis. Researchers studying the aerodynamics performance of multiple UAM designs are focusing this year on simulations to analyze how these vehicles perform close to the ground. Many of the agency’s UAM aircraft concepts have rotors, just like helicopters. Supercomputers at the NASA Advanced Supercomputing (NAS) facility at NASA’s Ames Research Center in California’s Silicon Valley run complex, high-fidelity computational fluid dynamics simulations that capture in detail the interaction between rotors, other vehicle components, and the ground surface. These simulations enable scientists to better understand the vehicle aerodynamics and the rotor-induced flow around the vehicles to detect potentially dangerous areas with high winds and gusts. Simulation data allows the team to predict changes in how UAMs handle close to the ground and to provide guidelines for safe crew and passenger movement near the vehicles.

Q-criterion — a measure of the amount of vorticity in the aerodynamic flow — isosurfaces colored with the vorticity magnitude show the vortex wake, where blue is low and magenta is high. In the background, the pressure coefficient is shown, where black is low and white is high. Understanding the complex flow and aerodynamic interactions of multi-rotor vehicles is key to design the future air taxis.

    2. Predicting the Strongest Storms within a Global Computer Model

    The common fuel for severe thunderstorms, tornadoes, and hurricanes is convection – vigorous up-and-down motions of the atmosphere that vertically transport heat and moisture. Operational weather forecasting centers typically predict convective-scale weather using regional, limited-area computer models because global models at convection resolving resolution need too much computing power. Researchers at NASA’s Goddard Space Flight Center in Greenbelt, Maryland, have adapted their global Goddard Earth Observing System (GEOS) model to apply finer grid resolutions of 2 to 4 kilometers (about 1.25 to 2.5 miles) over the continental United States. GEOS forecasts running on the NASA Center for Climate Simulation’s (NCCS’s) Discover supercomputer and NAS’s Aitken supercomputer are extending the predictability of the strongest storms beyond two days while better representing local impacts from intense precipitation, winds, and heat. Ongoing simulations accurately tracked extreme weather events of 2023 including hurricanes Idalia and Lee and tropical storm Ophelia.

    Hurricane Idalia made landfall along Florida’s northern Gulf Coast on August 30, 2023. Radar reflectivity from observations (left) and simulations by the Goddard Earth Observing System (GEOS) model at 4-kilometer (2.5-mile) (center) and 12-kilometer (7.5-mile) (right) resolution visualize Idalia’s internal structure. While both GEOS forecasts captured Idalia’s landfall within miles of the actual landfall days in advance, the 4- kilometer forecast improved representations of central pressure values, near-surface wind speeds, a very compact eye, and banding convection spiraling inwards from the southeast.

    3. Protecting Space Capsules During Planetary Entry, Descent, and Landing

    NASA space capsules are designed to survive entering planetary atmospheres at hypersonic speeds and protect their payloads – or their crew – from the extreme temperatures that occur during entry. In addition to heat, the spacecraft can also encounter instabilities as they are slowed down by aerodynamic drag during descent. To quantify and understand this additional hazard, researchers at NASA Ames used the agency’s Pleiades and Electra supercomputers to simulate the free-flight conditions of capsules during the full trajectory of planetary entry. These complex simulations are used to analyze capsule flight dynamics and identify any risks the instabilities may pose during the later stage of the flight trajectory. The resulting analyses help engineers design entry vehicles for planetary exploration, helping ensure the success of NASA programs including Artemis and the upcoming Dragonfly mission to Saturn’s largest moon, Titan.

    4. Transforming and Depicting Earth Science Data

    From the agency’s founding in 1958, NASA has been tasked with widely disseminating information about its activities and results. One new NASA public communication effort is the Earth Information Center (EIC), which presents visualizations of raw observational and model data across a set of dashboards arranged like a NASA Mission Control Center for our planet. The EIC installation at NASA Headquarters in Washington includes a multi-panel hyperwall for displaying large-format animations surrounded by smaller portals depicting a number of “vital signs” of the Earth. The diverse data sources include simulations run on the NCCS Discover supercomputer and observations from satellites and ground instruments maintained by NASA and partners. Since opening in late June 2023, the EIC has drawn a great variety of visitors, from dignitaries to elementary school students. In addition, EIC information is aiding policy makers, scientists, and NASA data users such as farmers, business owners, and researchers.

    5. Using Autonomous Onboard Science Agents for Planetary Exploration

    Researchers in NASA Goddard’s Distributed Systems Missions initiative are working to enable deep-space missions that are adaptable and can autonomously interpret and respond to newly-collected science data using an onboard software “agent” rather than waiting for new instructions from Earth at each phase of the mission. To test this new, autonomous mission design, they chose Enceladus, an icy ocean moon of Saturn and one of the most promising targets to search for life in our solar system. In a simulated mission scenario, the scientists modeled various trajectories and orbits of eight small spacecraft to produce what would be the first stable constellation around Enceladus to provide global coverage of the moon for collecting science observations. The team deployed their  autonomous onboard science agent to analyze simulated data in “real-time.” The agent uses multiple machine learning models to process and interpret the relative amounts of various compounds detected in Europa’s icy plumes – indicators of the possibility of life – autonomously interprets those data, then makes decisions impacting follow-on analysis or prioritized data transmission based on pre-programmed mission goals.   

    With its steady plume of subsurface liquid water jetting out into space, Saturn’s moon Enceladus is a likely candidate for an astrobiology study on a future NASA mission using autonomous spacecraft. In this visualization of that mission, the onboard system (science agent) tracks all eight spacecraft in the constellation (top center window). When the ground track lights up (shows white), the animation in the left window shows a close-up view of the position of that spacecraft. The spacecraft field of view is shown by a green cone (representing a volume of space) and corresponding green rectangle (on the surface). These spacecraft positions could be altered if strongly recommended by the science data results, and these changes can be safely executed autonomously.

  • NASA Associate Administrator Bob Cabana to Retire After 38 Years

    NASA Associate Administrator Bob Cabana delivers remarks during a Moon to Mars Town Hall, Thursday, May 18, 2023, at the Mary W. Jackson NASA Headquarters building in Washington.
    NASA/Keegan Barber

    NASA Associate Administrator and former astronaut Robert Cabana announced Monday his retirement, effective Sunday, Dec. 31 after more than 38 years of service. As associate administrator, Cabana has been the agency’s highest ranking civil servant, third highest ranking NASA official, and the senior advisor to NASA Administrator Bill Nelson and Deputy Administrator Pam Melroy.  

    Among notable contributions to the nation during his NASA career that included being an astronaut, Cabana flew in space four times, including twice as commander. His final space shuttle flight was the first International Space Station assembly mission. Cabana also was the director of the agency’s Kennedy Space Center in Florida for more than a decade. There he led its transition from retirement of the space shuttle to a multi-user spaceport once again launching NASA astronauts to low Earth orbit, and for the first time, doing so with commercial partners.  

    “Bob is one of the finest leaders I’ve ever known. I’ve been fortunate to know him for decades, and I couldn’t be prouder to have had such a great colleague and friend throughout the years. Bob is an example of the American grit, passion, and excellence that are woven into the fabric of our nation,” said Nelson. “Pam and I are eternally grateful for the years of service and positive influence he has had on the United States, NASA, and space exploration and wish him all the best on his upcoming retirement.”

    As associate administrator, Cabana leads NASA’s 10 center directors, as well as the mission directorate associate administrators at NASA Headquarters in Washington. He is the agency’s chief operating officer for more than 18,000 employees and oversaw an annual budget of more than $25 billion.  

    “Leading the exceptional people at NASA who explore the universe for the benefit of humanity has been a great honor,” said Cabana. “From flying in space to guiding teams across the agency in achieving NASA’s mission, I am grateful for an incredible career at NASA and in the space industry, and thankful for all the enriching friendships made throughout this journey. I have been blessed to be part of such an amazing team these last 38 years and serving as associate administrator alongside Bill and Pam has been a highlight.”

    Cabana was selected as an astronaut candidate in June 1985 and completed training in July 1986. He logged 38 days in space during four shuttle missions. Cabana was a pilot aboard space shuttle Discovery on both the STS-41 mission in October 1990 that deployed the Ulysses spacecraft and the STS-53 mission in December 1992. He was the mission commander aboard space shuttle Columbia for the STS-65 mission in July 1994 that conducted experiments as part of the second International Microgravity Laboratory mission. He commanded space shuttle Endeavour for the STS-88 mission in December 1998.

    Space Shuttle Endeavour Commander Robert Cabana prepares to return to Earth following successful delivery and mating of the first American module, Unity, to the International Space Station during the STS-88 mission.

    Cabana was appointed a member of the Federal Senior Executive Service in 2000 and served in numerous senior management positions at NASA’s Johnson Space Center in Houston, ultimately becoming deputy director. He was named director of NASA’s Stennis Space Center in Mississippi in October 2007 and a year later was selected as the Kennedy director. 

    Born in Minneapolis, Cabana graduated from the U.S. Naval Academy in 1971 with a bachelor’s degree in mathematics. He became a naval aviator and graduated with distinction from the U.S. Naval Test Pilot School in 1981. In his career, Cabana logged over 7,000 hours in more than 50 different kinds of aircraft. He retired as a colonel from the U.S. Marine Corps in September 2000. 

    Cabana’s many achievements have been recognized with induction into the Astronaut Hall of Fame and being named an Associate Fellow in the American Institute of Aeronautics and Astronautics and a Fellow in the Society of Experimental Test Pilots. He has received numerous personal awards and decorations, including the Distinguished Flying Cross and the Presidential Distinguished Rank Award. He also is a recipient of the Rotary National Award for Space Achievement’s National Space Trophy.

    Time Is Running Out to Add Your Name to NASA’s Europa Clipper

    “Message in a Bottle” campaign
    The “Message in a Bottle” campaign offers everyone the opportunity to have their name stenciled onto a microchip bearing U.S. Poet Laureate Ada Limón’s “In Praise of Mystery: A Poem for Europa.” The chip will ride aboard NASA’s Europa Clipper spacecraft to Jupiter and its moon Europa.
    NASA/JPL-Caltech

    Six weeks remain for you to add your name to a microchip that will ride aboard the spacecraft as it explores Jupiter’s moon Europa.

    It’s not every day that members of the public have the chance to send their names into deep space beyond Mars, all the way to Jupiter and its moon Europa. But with NASA’s Europa Clipper, you have that opportunity: Names will ride aboard the spacecraft as it journeys 1.8 billion miles (2.6 billion kilometers) to this icy moon, where an ocean hides beneath a frozen outer shell. The deadline to join the mission’s “Message in a Bottle” campaign is only six weeks away. The campaign closes at 11:59 p.m. EST, Dec. 31, 2023.

    So far, about 700,000 names have been submitted. Once all the names have been gathered, technicians in the Microdevices Laboratory at NASA’s Jet Propulsion Laboratory in Southern California will use an electron beam to stencil them onto a dime-size silicon microchip. Each line of text is smaller than 1/1000th the width of a human hair (75 nanometers).

    See how your name will be stenciled onto a dime-size microchip at NASA’s Jet Propulsion Laboratory. This video takes you into the Microdevices Laboratory. Credit: NASA/JPL-Caltech

    The chip will be attached to a metal plate engraved with the original poem “In Praise of Mystery,” written by U.S. Poet Laureate Ada Limón to celebrate the mission. Riding on the exterior of the spacecraft, the poem and names will be like a message in a bottle as they make about 50 close flybys of the ocean world.

    The mission will log a half-billion miles (800 million kilometers) during these orbits as the spacecraft’s payload of science instruments gathers data on Europa’s subsurface ocean, icy crust, and atmosphere to determine if the moon could support life.

    Once assembly of Europa Clipper has been completed at JPL, the orbiter will be shipped to NASA’s Kennedy Space Center in Florida in preparation for its October 2024 launch.

    “Message in a Bottle” draws from NASA’s long tradition of shipping inspirational messages on spacecraft that have explored our solar system and beyond. The program aims to spark the imaginations of people around the world as the Voyager spacecraft did in 1977 by sending a time capsule of sounds and images reflecting the diversity of life on Earth.

    To sign, read the poem, and hear Limón recite it in an animated video, go to:

    https://go.nasa.gov/MessageInABottle

    The site also enables participants to create and download a customizable souvenir – an illustration of your name on a message in a bottle against a rendering of Europa and Jupiter – to commemorate the experience. Participants are encouraged to share their enthusiasm on social media using the hashtag #SendYourName.

    More About the Mission

    Europa Clipper’s main science goal is to determine whether there are places below Jupiter’s icy moon, Europa, that could support life. The mission’s three main science objectives are to determine the thickness of the moon’s icy shell and its surface interactions with the ocean below, to investigate its composition, and to characterize its geology. The mission’s detailed exploration of Europa will help scientists better understand the astrobiological potential for habitable worlds beyond our planet.

    “The Launch Services Program is looking forward to having Denton in his new role as launch director,” Amanda Mitskevich, program manager of the Launch Services Program said. “He has contributed his talents in several technical and programmatic areas for NASA and now his experience will culminate in leading the team that will be launching some of NASA’s most important and valuable missions.  He’s going to be great at it!”

    Gibson began his career at Kennedy with NASA’s Launch Services Program in 2004, most recently serving as a senior mission manager. His experience involved serving as the primary interface between the program and customers from other NASA centers, federal agencies, federally funded science organizations, as well as international partners.

    “As a launch director, the responsibility for the entire mission falls to you when you give the final ‘go’ for launch,” Gibson said. “However, our meticulous preparations that begin years before the rocket is on the pad, and the amazing team we have, instill that confidence to say NASA is ready to launch.”

    Previous roles with the program have helped prepare Gibson for his new responsibilities. As a senior vehicle systems engineer discipline expert, Gibson led the program’s engineering team and was responsible for oversight and insight of a mixed fleet of commercial rockets. He expanded his leadership skills and industry experience during a detail assignment in 2016 to the U.S. Senate’s Space, Science, and Competitiveness Subcommittee staff working on U.S. space policy.

    Gibson earned a Bachelor of Science in electrical engineering from the University of Florida in Gainesville. He received a master’s in industrial engineering in 2006 from the University of Miami and a doctorate in systems engineering in 2019 from the University of Central Florida in Orlando.

    “Denton has accumulated knowledge of launch operations from his years of working advanced planning through integration, systems analysis, and launch” Dunn said. “His ability to ensure the readiness of spacecraft and rockets, as well as handling unique mission challenges that pop up, make him ready to lead the team on launch day.”

    Dunn and Gibson will be sharing the responsibilities for launching missions in 2024, including NASA’s PACE (Plankton, Aerosol, Cloud ocean Ecosystem); GOES-U, NOAA’s latest generation of Geostationary Operational Environmental Satellites; and NASA’s Europa Clipper, which will explore Jupiter’s icy moon and determine if it harbors conditions suitable for life. Gibson was born in Nassau, Bahamas, but considers Miami, Florida, where he grew up, to be his hometown.

    When Denton is not planning, implementing, and directing launch campaigns he enjoys building cars, scuba diving, working out and spending time with his daughter Phenix. He also is a professional salsa dancer, instructor, and choreographer.
