Better Monitoring of the Air Astronauts Breathe
Ten weeks of operations showed that a second version of the Spacecraft Atmosphere Monitor is sensitive enough to determine variations in the composition of cabin air inside the International Space Station. Volatile organic compounds and particulates in cabin air could pose a health risk for crew members, and this device increases the speed and accuracy of assessing such risk.
Spacecraft Atmosphere Monitor is a miniaturized gas chromatograph mass spectrometer used to analyze the air inside the space station and ensure that it is safe for the crew and equipment. The device automatically reports results to the ground, eliminating the need to return samples to Earth. This version has several other technological advances, including that it can be relocated, is smaller, and uses less power.

Prolonged exposure to microgravity affects human muscle precursor cells known as satellite cells and causes changes in the expression of specific genes involved in muscle structure and nerves. Exercise regimens on the space station do not adequately prevent or counteract muscle loss in astronauts, which can affect their motor function during missions and after return to Earth. Results could inform design of nutritional and pharmacological countermeasures to muscle changes during spaceflight.
Muscle loss represents a major obstacle to human long-term spaceflight. Myogravity, an investigation developed with the Italian space agency ASI, looked at microgravity-induced changes in adult stem cells involved in the growth, maintenance, and repair of skeletal muscle tissue, known as satellite cells. These cells may play a major role in muscle loss during spaceflight.

Researchers completed a preliminary evaluation of the station’s Hyperspectral Imager Suite (HISUI) and report that the difference between model-corrected and actual measurements is small. Validation of spaceborne optical sensors like HISUI is important to demonstrate they provide the accuracy needed for scientific research.
The JAXA (Japan Aerospace Exploration Agency) HISUI investigation tests a next-generation spaceborne hyperspectral Earth imaging system for gathering data on reflection of light from Earth’s surface, which reveals characteristics and physical properties of a target area. This technology has potential applications such as monitoring vegetation and identifying natural resources.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Stephanie Dudley, Gateway’s mission integration and utilization manager, sits inside a high-fidelity HALO (Habitation and Logistics Outpost) mockup at NASA’s Johnson Space Center.NASA/Josh Valcarcel Stephanie Dudley sits at the intersection of human spaceflight and science for Gateway, humanity’s first lunar space station that will host astronauts and unique scientific investigations.
Gateway’s mission integration and utilization manager, Dudley recently posed for this photo in a high-fidelity mockup of the space station’s HALO (Habitation and Logistics Outpost), where astronauts will live, conduct science, and prepare for missions to investigate the lunar South Pole region. Dudley works with NASA’s partner space agencies and academia to identify science opportunities on Gateway.
HALO will host various science experiments, including the Heliophysics Environmental and Radiation Measurement Experiment Suite, led by NASA, and the Internal Dosimeter Array, led by ESA (European Space Agency) and JAXA (Japan Aerospace Exploration Agency). The heliophysics experiment will fly on HALO’s exterior, and the dosimeter will be housed inside Gateway in a series of racks, mockups of which are shown to the right of Dudley in the image above. Both experiments will study solar and cosmic radiation to help the science community better understand how to protect astronauts and hardware during deep space travels to places like Mars.
“We are building [Gateway] for a 15-year lifespan, but definitely hope that we go longer than that,” Dudley recently said on Houston We Have a Podcast. “And so that many years of scientific study in a place where humans have never worked and lived long-term, Gateway is going to allow us to do that.”
Dudley pulls double duty as a deputy director for the Exploration Operations Office within NASA’s Moon to Mars Program, a role that connects her to Artemis science beyond Gateway, including science investigations on the Orion and Human Landing System spacecraft and lunar terrain vehicle.
“My work…is helping to make sure that across all of the six [Artemis] programs, including Gateway, we’re all focusing on utilization in the same way,” Dudley said.
Dudley’s team coordinates science payloads for Artemis II, the first mission to send humans to the Moon since 1972, and Artemis III, the first landing in the lunar South Pole region that is of keen interest to the global science community.
Gateway’s HALO will launch with the space station’s Power and Propulsion Element ahead of the Artemis IV mission in 2028, the first lunar mission to include an orbiting space station.
“Gateway sounds so science fiction, but it’s real,” Dudley recently said. “And we’re building it. And in a few years, it’s going to be around the Moon and that’s when the real work, the fun work in my opinion, is going to begin and science will never be the same.”
Gateway is humanity’s first lunar space station as a central component of the Artemis campaign that will return humans to the Moon for scientific discovery and chart a path for the first human missions to Mars.

Sols 4345-4347: Contact Science is Back on the Table
NASA’s Mars rover Curiosity acquired this image using its Right Navigation Camera on sol 4343 — Martian day 4,343 of the Mars Science Laboratory mission — on Oct. 24, 2024 at 15:26:28 UTC. NASA/JPL-Caltech Earth planning date: Friday, Oct. 25, 2024
The changes to the plan Wednesday, moving the drive a sol earlier, meant that we started off planning this morning about 18 meters (about 59 feet) farther along the western edge of Gediz Vallis and with all the data we needed for planning. This included the knowledge that once again one of Curiosity’s wheels was perched on a rock. Luckily, unlike on Wednesday, it was determined that it was safe to still go ahead with full contact science for this weekend. This consisted of two targets “Mount Brewer” and “Reef Lake,” two targets on the top and side of the same block.
Aside from the contact science, Curiosity has three sols to fill with remote imaging. The first two sols include “targeted science,” which means all the imaging of specific targets in our current workspace. Then, after we drive away on the second sol, we fill the final sol of the plan with “untargeted science,” where we care less about knowing exactly where the rover is ahead of time. A lot of the environmental team’s (or ENV) activities fall under this umbrella, which is why our dedicated “ENV Science Block” (about 30 minutes of environmental activities one morning every weekend) tends to fall at the end of a weekend plan.
But that’s getting ahead of myself. The weekend plan starts off with two ENV activities — a dust devil movie and a suprahorizon cloud movie. While cloud movies are almost always pointed in the same direction, our dust devil movie has to be specifically targeted. Recently we’ve been looking southeast toward a more sandy area (which you can see above), to see if we can catch dust lifting there. After those movies we hand the reins back over to the geology team (or GEO) for ChemCam observations of Reef Lake and “Poison Meadow.” Mastcam will follow this up with its own observations of Reef Lake and the AEGIS target from Wednesday’s plan. The rover gets some well-deserved rest before waking up for the contact science I talked about above, followed by a late evening Mastcam mosaic of “Fascination Turret,” a part of Gediz Vallis ridge that we’ve seen before.
We’re driving away on the second sol, but before that we have about another hour of science. ChemCam and Mastcam both have observations of “Heaven Lake” and the upper Gediz Vallis ridge, and ENV has a line-of-sight observation, to see how much dust is in the crater, and a pre-drive deck monitoring image to see if any dust moves around on the rover deck due to either driving or wind. Curiosity gets a short nap before a further drive of about 25 meters (about 82 feet).
The last sol of the weekend is a ChemCam special. AEGIS will autonomously choose a target for imaging, and then ChemCam has a passive sky observation to examine changing amounts of atmospheric gases. The weekend doesn’t end at midnight, though — we wake up in the morning for the promised morning ENV block, which we’ve filled with two cloud movies, another line-of-sight, and a tau observation to see how dusty the atmosphere is.

Educator Night at the Museum of the North: Activating Science in Fairbanks Classrooms
The NASA Heliophysics Education Activation Team (NASA HEAT) set out to activate science in Fairbanks classrooms in early October at the University of Alaska’s Museum of the North annual Educators’ Night. This free Fall semester event introduces educators and school staff to a variety of resources and connections, connecting attendees with resources and university departments that will support their classroom efforts.
In 2024, over 100 guests received support from exhibitors on classroom topics. The museum put several dynamic activity kits on display – Cultural Connections Northern Lights, Energetic Aurora, and Sun Discovery – and helped participants explore and engage with them as supplementary materials for their classroom units and opportunities for hands-on exploration. The museum also promoted an upcoming Spring 2025 teacher workshop focused on the aurora.
The Geophysical Institute’s (GI) Education Outreach Office – another active element of the NASA HEAT team – hosted a table to display some of their co-produced resources, including the Cultural Connections Northern Lights (Kiġuyat) student guides, which blend Iñupiaq culture and aurora borealis science. After directing educators on how to locate physical and digital resources, the GI Education Outreach team encouraged their visitors to wrap the term “heliophysics” into their own vocabulary!
The University of Alaska Museum of the North’s Education & Public Programs team are an impactful part of NASA HEAT, which is part of NASA’s Science Activation portfolio.
