NASA’s Human Landing System (HLS) will transport the next astronauts that land on the Moon, including the first woman and first person of color, beginning with Artemis III. For safety and mission success, the landers and other equipment in development for NASA’s Artemis campaign must work reliably in the harshest of environments.
The Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) lab at NASA’s Marshall Space Flight Center in Huntsville, Alabama, provides engineers with thermal analysis of materials that may be a prototype or in an early developmental stage using a vacuum chamber, back left, and a conduction chamber, right. NASA/Ken Hall Engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, are currently testing how well prototype insulation for SpaceX’s Starship HLS will insulate interior environments, including propellant storage tanks and the crew cabin. Starship HLS will land astronauts on the lunar surface during Artemis III and Artemis IV.
Marshall’s Hub for Innovative Thermal Technology Maturation and Prototyping (HI-TTeMP) laboratory provides the resources and tools for an early, quick-check evaluation of insulation materials destined for Artemis deep space missions.
“Marshall’s HI-TTeMP lab gives us a key testing capability to help determine how well the current materials being designed for vehicles like SpaceX’s orbital propellant storage depot and Starship HLS, will insulate the liquid oxygen and methane propellants,” said HLS chief engineer Rene Ortega. “By using this lab and the expertise provided by the thermal engineers at Marshall, we are gaining valuable feedback earlier in the design and development process that will provide additional information before qualifying hardware for deep space missions.”
A peek inside the conductive test chamber at NASA Marshall’s HI-TTeMP lab where thermal engineers design, set up, execute, and analyze materials destined for deep space to better understand how they will perform in the cold near-vacuum of space. NASA/Ken Hall On the Moon, spaceflight hardware like Starship HLS will face extreme temperatures. On the Moon’s south pole during lunar night, temperatures can plummet to -370 degrees Fahrenheit (-223 degrees Celsius). Elsewhere in deep space temperatures can range from roughly 250 degrees Fahrenheit (120 degrees Celsius) in direct sunlight to just above absolute zero in the shadows.
There are two primary means of managing thermal conditions: active and passive. Passive thermal controls include materials such as insulation, white paint, thermal blankets, and reflective metals. Engineers can also design operational controls, such as pointing thermally sensitive areas of a spacecraft away from direct sunlight, to help manage extreme thermal conditions. Active thermal control measures that could be used include radiators or cryogenic coolers.
Engineers use two vacuum test chambers in the lab to simulate the heat transfer effects of the deep space environment and to evaluate the thermal properties of the materials. One chamber is used to understand radiant heat, which directly warms an object in its path, such as when heat from the Sun shines on it. The other test chamber evaluates conduction by isolating and measuring its heat transfer paths.
NASA engineers working in the HI-TTeMP lab not only design, set up, and run tests, they also provide insight and expertise in thermal engineering to assist NASA’s industry partners, such as SpaceX and other organizations, in validating concepts and models, or suggesting changes to designs. The lab is able to rapidly test and evaluate design updates or iterations.
NASA’s HLS Program, managed by NASA Marshall, is charged with safely landing astronauts on the Moon as part of Artemis. NASA has awarded contracts to SpaceX for landing services for Artemis III and IV and to Blue Origin for Artemis V. Both landing services providers plan to transfer super-cold propellant in space to send landers to the Moon with full tanks.
With Artemis, NASA will explore more of the Moon than ever before, learn how to live and work away from home, and prepare for future human exploration of Mars. NASA’s SLS (Space Launch System) rocket, exploration ground systems, and Orion spacecraft, along with the HLS, next-generation spacesuits, Gateway lunar space station, and future rovers are NASA’s foundation for deep space exploration.

From left to right, Dr. Peter Parker, Astronaut Victor Glover and Dr. Shih-Yung post for a photo after the 2024 Silver Snoopy Awards ceremony.NASA/Mark Knopp Two employees from NASA’s Langley Research Center in Hampton, Virginia recently earned the prestigious Silver Snoopy award, an honor given to NASA employees and contractors across the agency for outstanding achievements related to astronaut safety or mission success. Dr. Shih-Yung Lin and Dr. Peter Parker received the awards during a Space Flight Awareness (SFA) award ceremony at Langley on Nov. 21. Lin earned the award for exceptional engineering and technical leadership contributions to the Orion program. Parker earned the award for outstanding leadership and technical contributions in support of the International Space Station (ISS).
NASA astronaut Victor Glover visited Langley to present the awards. Glover is currently assigned as the pilot of NASA’s Artemis II mission to the Moon. He piloted the SpaceX Crew 1 mission to the International Space Station in 2018 and served as a flight engineer on expeditions 64 and 65.
“This, for me, feels like how I felt when I received my astronaut pin. This is us giving you our team pin,” said Glover. He later added, “This is something to wear with honor. You are a very special part of our safety and mission assurance culture.”
Astronaut Victor Glover presents the 2024 Silver Snoopy Awards to Dr. Shih-Yung at NASA Langley Research Center.NASA/Angelique Herring The Silver Snoopy is the astronauts’ personal award and is presented to less than one percent of the total NASA workforce annually. The significance of the award was not lost on the honorees, who both brought family members to share in the moment.
“I’m involved with lots of research projects, but they don’t all involve loss of human life,” said Parker. “It definitely is a more prestigious, more impactful, more consequential type of project that I’m being recognized for.”
Lin, who recently retired, echoed that sentiment.
“You set a very high standard in order to achieve the safest conditions for all the astronauts,” he said. “For me, if we get a good mission out of it, or multiple missions, I would consider that my personal lifetime goal for my career. That’s what it means to me.”
Lin and Parker each received a sterling Silver Snoopy lapel pin that has flown in space, plus a certificate of appreciation signed by Glover and an authentication letter. The pins awarded to Langley’s recipients flew aboard Space Shuttle Endeavour during an assembly mission to the International Space Station, STS-118, August 8-21, 2007. The award depicts Snoopy, a character from the “Peanuts” comic strip created by Charles Schulz.
An avid supporter of the U.S. space program, Schulz gave NASA astronauts permission to adopt Snoopy as their personal safety symbol during the Apollo era and has long served to promote excellence in every phase of space flight to help ensure the success of NASA missions. The Snoopy emblem reflects NASA and industry’s sense of responsibility and continuing concern for astronaut flight safety.

The International Space Station is humanity’s home in space and a research station orbiting about 250 miles above the Earth. NASA and its international partners have maintained a continuous human presence aboard the space station for more than 24 years, conducting research that is not possible on Earth.
The people living and working aboard the microgravity laboratory also are part of the research being conducted, helping to address complex human health issues on Earth and prepare humanity for travel farther than ever before, including the Moon and Mars.
Here are a few frequently asked questions about how NASA and its team of medical physicians, psychologists, nutritionists, exercise scientists, and other specialized caretakers ensure astronauts’ health and fitness aboard the orbiting laboratory.
How long is a typical stay aboard the International Space Station?
A typical mission to the International Space Station lasts about six months, but can vary based on visiting spacecraft schedules, mission priorities, and other factors. NASA astronauts also have remained aboard the space station for longer periods of time. These are known as long-duration missions, and previous missions have given NASA volumes of data about long-term spaceflight and its effects on the human body, which the agency applies to any crewed mission.
During long-duration missions, NASA’s team of medical professionals focus on optimizing astronauts’ physical and behavioral health and their performance to help ensure mission success. These efforts also are helping NASA prepare for future human missions to the Moon, Mars, and beyond.
How does NASA keep astronauts healthy while in space?
NASA has a team of medical doctors, psychologists, and others on the ground dedicated to supporting the health and well-being of astronauts before, during, and after each space mission. NASA assigns physicians with specialized training in space medicine, called flight surgeons, to each crew once named to a mission. Flight surgeons oversee the health care and medical training as crew members prepare for their mission, and they monitor the crew’s health before, during, and after their mission to the space station.
How does NASA support its astronauts’ mental and emotional well-being while in space?
The NASA behavioral health team provides individually determined psychological support services for crew members and their families during each mission. Ensuring astronauts can thrive in extreme environments starts as early as the astronaut selection process, in which applicants are evaluated on competencies such as adaptability and resilience. Astronauts receive extensive training to help them use self-assessment tools and treatments to manage their behavioral health. NASA also provides training in expeditionary skills to prepare every astronaut for missions on important competencies, such as self-care and team care, communication, and leadership and followership skills.
To help maintain motivation and morale aboard the space station, astronauts can email, call, and video conference with their family and friends, receive crew care packages aboard NASA’s cargo resupply missions, and teleconference with a psychologist, if needed.
How does microgravity affect astronaut physical health?
In microgravity, without the continuous load of Earth’s gravity, there are many changes to the human body. NASA understands many of the human system responses to the space environment, including adaptations to bone density, muscle, sensory-motor, and cardiovascular health, but there is still much to learn. These spaceflight effects vary from astronaut to astronaut, so NASA flight surgeons regularly monitor each crew member’s health during a mission and individualize diet and fitness routines to prioritize health and fitness while in space.
Why do astronauts exercise in space?
Each astronaut aboard the orbiting laboratory engages in specifically designed, Earth-like exercise plans. To maintain their strength and endurance, crew members are scheduled for two and a half hours of daily exercise to support muscle, bone, aerobic, and sensorimotor health. Current equipment onboard the space station includes the ARED (Advanced Resistive Exercise Device), which mimics weightlifting; a treadmill, called T2; and the CEVIS (Cycle Ergometer with Vibration Isolation and Stabilization System) for cardiovascular exercise.
What roles do food and nutrition play in supporting astronaut health?
Nutrition plays a critical role in maintaining an astronaut’s health and optimal performance before, during, and after their mission. Food also plays a psychosocial role during an astronaut’s long-duration stay aboard the space station. Experts working in NASA’s Space Food Systems Laboratory at the agency’s Johnson Space Center in Houston develop foods that are nutritious and appetizing. Crew members also have the opportunity to supplement the menu with personal favorites and off-the-shelf items, which can provide a taste of home.
NASA astronaut and Expedition 71 Flight Engineer Tracy C. Dyson is pictured in the galley aboard the International Space Station’s Unity module showing off food packets from JAXA (Japan Aerospace Exploration Agency).NASA How does NASA know whether astronauts are getting the proper nutrients?
NASA’s nutritional biochemistry dietitians and scientists determine the nutrients (vitamins, minerals, calories) the astronauts require while in space. This team tracks what each crew member eats through a tablet-based tracking program, which each astronaut completes daily. The data from the app is sent to the dietitians weekly to monitor dietary intake. Analyzing astronaut blood and urine samples taken before, during, and after space missions is a crucial part of studying how their bodies respond to the unique conditions of spaceflight. These samples provide valuable insight into how each astronaut adapts to microgravity, radiation, and other factors that affect human physiology in space.
How do astronauts train to work together while in space?
In addition to technical training, astronauts participate in team skills training. They learn effective group living skills and how to look out for and support one another. Due to its remote and isolated nature, long-duration spaceflight can make teamwork difficult. Astronauts must maintain situational awareness and implement the flight program in an ever-changing environment. Therefore, effective communication is critical when working as a team aboard station and with multiple support teams on the ground. Astronauts also need to be able to communicate complex information to people with different professional backgrounds. Ultimately, astronauts are people living and working together aboard the station and must be able to do a highly technical job and resolve any interpersonal issues that might arise.
What happens if there is a medical emergency on the space station?
All astronauts undergo medical training and have regular contact with a team of doctors closely monitoring their health on the ground. NASA also maintains a robust pharmacy and a suite of medical equipment onboard the space station to treat various conditions and injuries. If a medical emergency requires a return to Earth, the crew will return in the spacecraft they launched aboard to receive urgent medical care on the ground.

5 Surprising NASA Heliophysics Discoveries Not Related to the Sun
With NASA’s fleet of heliophysics spacecraft, scientists monitor our Sun and investigate its influences throughout the solar system. However, the fleet’s constant watch and often-unique perspectives sometimes create opportunities to make discoveries that no one expected, helping us to solve mysteries about of the solar system and beyond.
Here are five examples of breakthroughs made by NASA heliophysics missions in other fields of science.
This graphic shows missions in NASA’s Heliophysics Division fleet as of July 2024. NASA Thousands and Thousands of Comets
The SOHO mission — short for Solar and Heliospheric Observatory, which is a joint mission between ESA (European Space Agency) and NASA — has a coronagraph that blocks out the Sun in order to see the Sun’s faint outer atmosphere, or corona.
It turns out SOHO’s coronagraph also makes it easy to spot sungrazing comets, those that pass so close to the Sun that other observatories can’t see them against the brightness of our star.
Before SOHO was launched in December 1995, fewer than 20 sungrazing comets were known. Since then, SOHO has discovered more than 5,000.
The vast number of comets discovered using SOHO has allowed scientists to learn more about sungrazing comets and identify comet families, descended from ancestor comets that broke up long ago.

Two sungrazing comets fly close to the Sun in these images captured by ESA/NASA’s SOHO (Solar and Heliospheric Observatory). They were the 3,999th and 4,000th comets discovered in SOHO images. ESA/NASA/SOHO/Karl Battams Dimming of a Supergiant
In late 2019, the supergiant star Betelgeuse began dimming unexpectedly. Telescopes all over the world — and around it — tracked these changes until a few months later when Betelgeuse appeared too close to the Sun to observe. That’s when NASA’s STEREO (Sun-watching Solar Terrestrial Relations Observatory (STEREO) came to the rescue.
For several weeks in the middle of 2020, STEREO was the only observatory able to see Betelgeuse. At the time, the STEREO-A spacecraft was trailing behind Earth, at a vantage point where Betelgeuse was still far enough away from the Sun to be seen. This allowed astronomers to keep tabs on the star while it was out of view from Earth.
STEREO’s observations revealed another unexpected dimming between June and August of 2020, when ground-based telescopes couldn’t view the star.
Astronomers later concluded that these dimming episodes were caused by an ejection of mass from Betelgeuse — like a coronal mass ejection from our Sun but with about 400 times more mass — which obscured part of the star’s bright surface.

The background image shows the star Betelgeuse as seen by the Heliospheric Imager aboard NASA’s STEREO (Solar Terrestrial Relations Observatory) spacecraft. The inset figure shows measurements of Betelgeuse’s brightness taken by different observatories from late 2018 to late 2020. STEREO’s observations, marked in red, revealed an unexpected dimming in mid-2020 when Betelgeuse appeared too close to the Sun for other observatories to view it. NASA/STEREO/HI (background); Dupree et al. (inset) The Glowing Surface of Venus
NASA’s Parker Solar Probe studies the Sun’s corona up close — by flying through it. To dive into the Sun’s outer atmosphere, the spacecraft has flown past Venus several times, using the planet’s gravity to fling itself closer and closer to the Sun.
On July 11, 2020, during Parker’s third Venus flyby, scientists used Parker’s wide-field imager, called WISPR, to try to measure the speed of the clouds that obscure Venus’ surface. Surprisingly, WISPR not only observed the clouds, it also saw through them to the surface below.
The images from that flyby and the next (in 2021) revealed a faint glow from Venus’ hot surface in near-infrared light and long wavelengths of red (visible) light that maps distinctive features like mountainous regions, plains, and plateaus.
Scientists aimed WISPR at Venus again on Nov. 6, 2024, during Parker’s seventh flyby, observing a different part of the planet than previous flybys. With these images, they’re hoping to learn more about Venus’ surface geology, mineralogy, and evolution.

As Parker Solar Probe flew by Venus on its fourth flyby, it captured these images, strung into a video, showing bright and dark features on the nightside surface of the planet. NASA/APL/NRL The Brightest Gamma-Ray Burst
You’ve heard of the GOAT. But have you heard of the BOAT?
It stands for the “brightest of all time”, a gamma-ray burst discovered on Oct. 9, 2022.
A gamma-ray burst is a brief but intense eruption of gamma rays in space, lasting from seconds to hours.
This one, named GRB 221009A, glowed brilliantly for about 10 minutes in the constellation Sagitta before slowly fading.
The burst was detected by dozens of spacecraft, including NASA’s Wind, which studies the perpetual flow of particles from the Sun, called the solar wind, just before it reaches Earth.
Wind and NASA’s Fermi Gamma-Ray Space Telescope measured the brightness of GRB 221009A, showing that it was 70 times brighter than any other gamma-ray burst ever recorded by humans — solidifying its status as the BOAT.
Learn More
Astronomers think GRB 221009A represents the birth of a new black hole formed within the heart of a collapsing star. In this artist’s concept, the black hole drives powerful jets of particles traveling near the speed of light. The jets emit X-rays and gamma rays as they stream into space. NASA/Swift/Cruz deWilde A Volcano Blasts Its Way to Space
NASA’s ICON (Ionospheric Connection Explorer) launched in 2019 to study how Earth’s weather interacts with weather from space. When the underwater Hunga Tonga-Hunga Ha‘apai volcano erupted on Jan. 15, 2022, ICON helped show that the volcano produced more than ash and tsunami waves — its effects reached the edge of space.
In the hours after the eruption, ICON detected hurricane-speed winds in the ionosphere — Earth’s electrified upper atmospheric layer at the edge of space. ICON clocked the wind speeds at up to 450 miles per hour, making them the strongest winds the mission had ever measured below 120 miles altitude.
The ESA Swarm mission revealed that these extreme winds altered an electric current in the ionosphere called the equatorial electrojet. After the eruption, the equatorial electrojet surged to five times its normal peak power and dramatically flipped direction.
Scientists were surprised that a volcano could affect the electrojet so severely — something they’d only seen during a strong geomagnetic storm caused by an eruption from the Sun.

The Hunga Tonga-Hunga Ha’apai eruption on Jan. 15, 2022, caused many effects, some illustrated here, that were felt around the world and even into space. Some of those effects, like extreme winds and unusual electric currents were picked up by NASA’s ICON (Ionospheric Connection Explorer) mission and ESA’s (the European Space Agency) Swarm.
