A NASA photographer captured the full “wolf” moon rising over the Lincoln Memorial and Memorial Bridge on Jan. 13, 2025.

The Maine Farmers’ Almanac began publishing Native American names for full moons in the 1930s. Over time, these names have become widely known and used. According to this almanac, the full moon in January is called the Wolf Moon, from the packs of wolves heard howling outside the villages amid the cold and deep snows of winter.

Reducing reliance on resupply missions

Resupply of life support elements such as air, water, food, clothing, and hygiene items will be impractical on missions to the Moon and beyond. This research assessed current use and resupply of these elements on the International Space Station and outlines technologies needed for sustained human presence in space, such as 3D printing maintenance parts, systems for laundering clothes, and improved recovery and recycling of elements.

Researchers analyzed the types and mass of elements supplied from Earth to the station and astronaut feedback from various studies and interviews. The paper also used data from ISS Internal Environments, a wide-ranging investigation that samples various aspects of the space station environment in support of many types of research.

Verifying a technique for analyzing emulsions

This paper presents a review of examining the behavior of emulsions (suspensions of particles in a liquid) in microgravity using a technique called diffusing wave spectroscopy. Results offer insights that could support development of technologies to improve living environments and foods for crew members on future missions.

FSL Soft Matter Dynamics – PASTA studied the dynamics of droplets in emulsions. Accurate study and characterization of the effects of additives on emulsion stability is possible in microgravity. Emulsions have applications in foods, cosmetics, pharmaceuticals, fuels, paints and coatings, chemical processing, and materials.

EEG measurements and predicting cognitive changes in spaceflight

Researchers used an electroencephalogram (EEG) to measure brainwave activity during a relaxed, wakeful state in crew members and found no significant differences before, during, and after flight. These types of measurements could serve as biomarkers of brain health status, helping to predict changes in cognitive performance and the need for prevention and countermeasure strategies during future missions.

Studies have shown that spaceflight can affect key cognitive and motor skills such as task management, attention, and movement speed and accuracy. Neurowellness in Space Ax-1 tested using a portable, easy to use EEG headset to measure ongoing and task-related brain activity in microgravity. The data could help predict and monitor neural changes on future space missions.

Astronomers have taken a crucial step in showing that the most massive black holes in the universe can create their own meals. Data from NASA’s Chandra X-ray Observatory and the Very Large Telescope (VLT) provide new evidence that outbursts from black holes can help cool down gas to feed themselves.

This study was based on observations of seven clusters of galaxies. The centers of galaxy clusters contain the universe’s most massive galaxies, which harbor huge black holes with masses ranging from millions to tens of billions of times that of the Sun. Jets from these black holes are driven by the black holes feasting on gas.

These images show two of the galaxy clusters in the study, the Perseus Cluster and the Centaurus Cluster. Chandra data represented in blue reveals X-rays from filaments of hot gas, and data from the VLT, an optical telescope in Chile, shows cooler filaments in red.

The results support a model where outbursts from the black holes trigger hot gas to cool and form narrow filaments of warm gas. Turbulence in the gas also plays an important role in this triggering process.

According to this model, some of the warm gas in these filaments should then flow into the centers of the galaxies to feed the black holes, causing an outburst. The outburst causes more gas to cool and feed the black holes, leading to further outbursts.

This model predicts there will be a relationship between the brightness of filaments of hot and warm gas in the centers of galaxy clusters. More specifically, in regions where the hot gas is brighter, the warm gas should also be brighter. The team of astronomers has, for the first time, discovered such a relationship, giving critical support for the model.

This result also provides new understanding of these gas-filled filaments, which are important not just for feeding black holes but also for causing new stars to form. This advance was made possible by an innovative technique that isolates the hot filaments in the Chandra X-ray data from other structures, including large cavities in the hot gas created by the black hole’s jets.

The newly found relationship for these filaments shows remarkable similarity to the one found in the tails of jellyfish galaxies, which have had gas stripped away from them as they travel through surrounding gas, forming long tails. This similarity reveals an unexpected cosmic connection between the two objects and implies a similar process is occurring in these objects.

This work was led by Valeria Olivares from the University of Santiago de Chile, and was published Monday in Nature Astronomy. The study brought together international experts in optical and X-ray observations and simulations from the United States, Chile, Australia, Canada, and Italy. The work relied on the capabilities of the MUSE (Multi Unit Spectroscopic Explorer) instrument on the VLT, which generates 3D views of the universe.

NASA’s Marshall Space Flight Center in Huntsville, Alabama, manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science operations from Cambridge, Massachusetts, and flight operations from Burlington, Massachusetts.

Visual Description

This release features composite images shown side-by-side of two different galaxy clusters, each with a central black hole surrounded by patches and filaments of gas. The galaxy clusters, known as Perseus and Centaurus, are two of seven galaxy clusters observed as part of an international study led by the University of Santiago de Chile.

In each image, a patch of purple with neon pink veins floats in the blackness of space, surrounded by flecks of light. At the center of each patch is a glowing, bright white dot. The bright white dots are black holes. The purple patches represent hot X-ray gas, and the neon pink veins represent filaments of warm gas. According to the model published in the study, jets from the black holes impact the hot X-ray gas. This gas cools into warm filaments, with some warm gas flowing back into the black hole. The return flow of warm gas causes jets to again cool the hot gas, triggering the cycle once again.

While the images of the two galaxy clusters are broadly similar, there are significant visual differences. In the image of the Perseus Cluster on the left, the surrounding flecks of light are larger and brighter, making the individual galaxies they represent easier to discern. Here, the purple gas has a blue tint, and the hot pink filaments appear solid, as if rendered with quivering strokes of a paintbrush. In the image of the Centaurus Cluster on the right, the purple gas appears softer, with a more diffuse quality. The filaments are rendered in more detail, with feathery edges, and gradation in color ranging from pale pink to neon red.

NASA’s NICER Continues Science Operations Post Repair

NASA crew aboard the International Space Station installed patches to the agency’s NICER (Neutron star Interior Composition Explorer) mission during a spacewalk on Jan. 16. NICER, an X-ray telescope perched near the station’s starboard solar array, resumed science operations later the same day.

The patches cover areas of NICER’s thermal shields where damage was discovered in May 2023. These thin filters block sunlight while allowing X-rays to pass through. After the discovery, the NICER team restricted their observations during the station’s daytime to avoid overwhelming the mission’s sensitive detectors. Nighttime observations were unaffected, and the team was able to continue collecting data for the science community to make groundbreaking measurements using the instrument’s full capabilities.

The repair went according to plan. Data since collected shows the detectors behind the patched areas are performing better than before during station night, and the overall level of sunlight inside NICER during the daytime is reduced substantially.

While NICER experiences less interference from sunlight than before, after analyzing initial data, the team has determined the telescope still experiences more interference than expected. The installed patches cover areas of known damage identified using astronomical observations and from photos taken by both external robotic cameras and astronauts inside the space station. Measurements collected since the repair and close-up, high-resolution photos obtained during the spacewalk are providing new information that may point the way toward further daytime data collection.

In the meantime, NICER continues operations with its full measurement capabilities during orbit night to enable further trailblazing discoveries in time domain and multimessenger astrophysics.

Sunlight ‘Leak’ Impacting NASA’s NICER Telescope, Science Continues

On Tuesday, May 22, NASA’s NICER (Neutron Star Interior Composition Explorer), an X-ray telescope on the International Space Station, developed a “light leak,” in which unwanted sunlight enters the instrument. While analyzing incoming data since then, the team identified an impact to daytime observations. Nighttime observations seem to be unaffected.

The team suspects that at least one of the thin thermal shields on NICER’s 56 X-ray Concentrators has been damaged, allowing sunlight to reach its sensitive detectors.

To mitigate the effects on measurements, the NICER team has limited daytime observations to objects far away from the Sun’s position in the sky. The team has also updated commands to NICER that automatically lower its sensitivity during the orbital day to reduce the effects from sunlight contamination. The team is evaluating these changes and assessing additional measures to reduce the impact on science observations.

To date, more than 300 scientific papers have used NICER observations, and the team is confident that NICER will continue to produce world-class science.

Jon Carabello did not begin his career journey with an eye on space, but when NASA’s Artemis lunar exploration campaign came calling, he was all in.

Born, raised, and college-educated in New Hampshire, Carabello has spent his entire professional career at TURBOCAM – a turbomachinery development and manufacturing company – in the southeast corner of the Granite State. 

That’s a long way from the southern and western states commonly associated with U.S. human spaceflight activities.

Asked about his early memories of America’s space program, Carabello mentions movies like Apollo 13, and notes that Christa McAulliffe, the teacher-astronaut who died in the 1986 Space Shuttle Challenger accident, taught high school in New Hampshire.

Little did he know that his future employer, a maker of complex machined hardware for a variety of industrial applications, has long been a component supplier to programs including the Space Shuttle and the International Space Station.

There was never much question that Carabello, who started tinkering with engines and other machinery at a young age, would make a career of mechanical engineering. “I like to solve problems – that’s my big thing,” he says. 

He learned about TURBOCAM when company representatives made a presentation to his University of New Hampshire engineering class. “That’s how I figured out I knew wanted to work at TURBOCAM and work with 5-axis machining,” he says. “Machining amazes me.”

Five axis machine tools can machine metal blanks from multiple angles to create geometrically complex parts for industrial hardware. TURBOCAM produces 10 core stage main engine turbomachinery components for the RS-25 main engine on NASA’s SLS (Space Launch System) heavy lift exploration rocket. L3Harris Technologies is the prime contractor for the RS-25 engines.

It was his fascination with machining rather than the opportunity to work on rocket engines that drew Carabello to TURBOCAM, where he initially worked on machinery for the oil and gas industry, heating and air conditioning systems, and aerospace. 

But then one day, a supervisor asked him to take over the company’s RS-25 portfolio. He remembers the conversion quite clearly.

“It was a Thursday afternoon,” he says. “I was sitting in my office and my manager came in and said, ‘we have somebody leaving and need someone to take over project management and ownership of the RS-25.’ I said, ‘yes’ and he said, ‘you have a call with the program tomorrow.’ That was about five years ago.”

It was a significant change, but Carabello knew the company needed his problem-solving skills on the RS-25 program. “I know how to bring a team together to deliver a quality product. It’s rewarding to know I’m helping return humans to the Moon and paving the way to Mars with the Artemis campaign.”

Self-confidence notwithstanding, Carabello admits to being a bit nervous given that NASA astronauts will be relying on his work. That point was driven home when NASA and L3Harris representatives visited TURBOCAM in the spring of 2024 for a series of presentations on Artemis. The remark that resonated with him the most was by NASA astronaut Dr. Lee Morin, who said the most important part of any human spaceflight mission is bringing astronauts safely home. 

“That meant a lot to me,” says Carabello, whose team is responsible for all aspects of TURBOCAM’S RS-25 effort, including quality control, inspection, and resource allocation. He is constantly reminding his team of what’s really at stake for astronauts bound for space: “We’re helping them to return home,” he says.

On Jan. 19, 1965, Gemini 2 successfully completed the second of two uncrewed test flights of the spacecraft and its Titan II booster, clearing the way for the first crewed mission. The 18-minute suborbital mission achieved the primary goals of flight qualifying the Gemini spacecraft, especially its heat shield during a stressful reentry. Recovery forces retrieved the capsule following its splashdown, allowing engineers to evaluate how its systems fared during the flight. The success of Gemini 2 enabled the first crewed mission to fly two months later, beginning a series of 10 flights over the following 20 months. The astronauts who flew these missions demonstrated the rendezvous and docking techniques necessary to implement the Lunar Orbit Rendezvous method NASA chose for the Moon landing mission. They also proved that astronauts could work outside their spacecraft during spacewalks and that spacecraft and astronauts could function for at least eight days, the minimum time for a roundtrip lunar mission. The Gemini program proved critical to fulfill President John F. Kennedy’s goal of landing a man on the Moon and returning him safely to Earth before the end of the 1960s. 

Following the success of Gemini 1 in April 1964, NASA had hoped to fly the second mission before the end of the year and the first crewed mission by January 1965. The two stages of the Titan II rocket arrived at Cape Kennedy from the Martin Marietta factory in Baltimore on July 11, and workers erected it on Launch Pad 19 five days later. A lightning strike at the pad on Aug. 17 invalidated all previous testing and required replacement of some pad equipment. A series of three hurricanes in August and September forced workers to partially or totally unstack the vehicle before stacking it for the final time on Sept. 14. The Gemini 2 spacecraft arrived at Cape Kennedy from its builder, the McDonnell Company in St. Louis, on Sept. 21, and workers hoisted it to the top of the Titan II on Oct. 18. Technical issues delayed the spacecraft’s physical mating to the rocket until Nov. 5. These accumulated delays pushed the launch date back to Dec. 9. 

Fueling of the rocket began late on Dec. 8, and following three brief holds in the countdown, the Titan’s two first stage engines ignited at 11:41 a.m. EST on Dec. 9. and promptly shut down one second later. Engineers later determined that a cracked valve resulted in loss of hydraulic pressure, causing the malfunction detection system to switch to its backup mode, forcing a shutdown of the engines. Repairs meant a delay into the new year. On Jan. 19, 1965, following a mostly smooth countdown, Gemini 2 lifted off from Pad 19 at 9:04 a.m. EST. 

In the Gemini Mission Control Center at NASA’s Kennedy Space Center in Florida, Flight Director Christopher C. Kraft led a team of flight controllers that monitored all aspects of the flight. At the Manned Spacecraft Center (MSC), now NASA’s Johnson Space Center in Houston, a team of controllers led by Flight Director John Hodge passively monitored the flight from the newly built Mission Control Center. They would act as observers for this flight and Gemini 3, the first crewed mission, before taking over full control with Gemini IV, and control all subsequent American human spaceflights. The Titan rocket’s two stages placed Gemini 2 into a suborbital trajectory, reaching a maximum altitude of 98.9 miles, with the vehicle attaining a maximum velocity of 16,709 miles per hour. Within a minute after separating from the Titan’s second stage, Gemini 2 executed a maneuver to orient its heat shield in the direction of flight to prepare for reentry. Flight simulators installed where the astronauts normally would sit controlled the maneuvers. About seven minutes after liftoff, Gemini 2 jettisoned its equipment section, followed by firing of the retrorockets, and then separation of the retrorocket section, exposing the spacecraft’s heat shield. 

Gemini 2 then began its reentry, the heat shield protecting the spacecraft from the 2,000-degree heat generated by friction with the Earth’s upper atmosphere. A pilot parachute pulled away the rendezvous and recovery section. At 10,000 feet, the main parachute deployed, and Gemini 2 descended to a splashdown 2,127 miles from its launch pad, after a flight of 18 minutes 16 seconds. The splashdown took place in the Atlantic Ocean about 800 miles east of San Juan, Puerto Rico, and 25 miles from the prime recovery ship, the U.S.S. Lake Champlain (CVS-39). 

U.S. Navy helicopters delivered divers to the splashdown area, who installed a flotation collar around the spacecraft. The Lake Champlain pulled alongside, and sailors hoisted the capsule onto the carrier, securing it on deck one hour forty minutes after liftoff. The spacecraft appeared to be in good condition and arrived back at Cape Kennedy on Jan. 22 for a thorough inspection. As an added bonus, sailors recovered the rendezvous and recovery section. Astronaut Virgil “Gus” Grissom, whom along with John Young NASA had selected to fly the first crewed Gemini mission, said after the splashdown, “We now see the road clear to our flight, and we’re looking forward to it.” Flight Director Kraft called it “very successful.” Gemini Program Manager Charles Matthews predicted the first crewed mission could occur within three months. Gemini 3 actually launched on March 23.

Postscript 

Gemini 2 not only cleared the way for the first crewed Gemini mission and the rest of the program, it also took on a second life as a test vehicle for the U.S. Air Force’s Manned Orbiting Laboratory (MOL). The Air Force modified the spacecraft, including cutting a hatch through its heat shield, renamed it Gemini-B, and launched it on Nov. 3, 1966, atop a Titan IIIC rocket. The test flight successfully demonstrated the hatch in the heat shield design during the capsule’s reentry after a 33-minute suborbital flight. Recovery forces retrieved the Gemini-B capsule in the South Atlantic Ocean and returned it to the Air Force for postflight inspection. This marked the only repeat flight of an American spacecraft intended for human spaceflight until the advent of the space shuttle. Visitors can view Gemini 2/Gemini-B on display at the Cape Canaveral Space Force Museum.  

Astronauts are scheduled to venture outside the International Space Station to collect microbiological samples during crew spacewalks for the ISS External Microorganisms experiment. This investigation focuses on sampling at sites near life support system vents to examine whether the spacecraft releases microorganisms, how many, and how far they may travel.

This experiment could help researchers understand whether and how these microorganisms survive and reproduce in the harsh space environment and how they may perform at planetary destinations such as the Moon and Mars. Extremophiles, or microorganisms that can survive harsh environments, are also of interest to industries on Earth such as pharmaceuticals and agriculture.

Spacecrafts and spacesuits are thoroughly sterilized before missions; however, humans carry their own microbiomes and continuously regenerate microbial communities. It’s important to understand and address how well current designs and processes prevent or limit the spread of human contamination.  The data could help determine whether changes are needed to crewed spacecraft, including spacesuits, that are used to explore destinations where life may exist now or in the past.
