Researchers tested a treatment on cartilage and bone tissue cultures subjected to compressive impact injury and found differences in the metabolites and proteins released by cells in space and on Earth along with partial improvement in both gravity conditions. The findings suggest the treatment is safe and could help ensure the health of crew members on future missions and patients on Earth.

Astronauts have high rates of musculoskeletal injuries, and post-traumatic osteoarthritis from joint injuries is a major contributor to disability across all ages on the ground. MVP Cell-06 used cultures of human knee cartilage and bone cells from two donors to study how spaceflight affects musculoskeletal disease. Results could lead to ways to prevent and treat bone and cartilage degradation in astronauts and people on Earth following joint injury.

NASA and Roscosmos researchers examined brazing of an aluminum-silicon material and found that gravity had a moderate effect with small quantities of the alloy and a more significant effect with larger quantities. The finding could inform techniques for manufacturing on future space missions.

SUBSA-BRAINS examined capillary flow, interface reactions, and bubble formation during solidification of brazing alloys in microgravity. Brazing, which bonds similar and dissimilar materials at temperatures above 450°C, is a potential tool for construction, manufacture, and repair of space vehicles and habitats.

Analysis of the pain experience of two Axiom-1 astronauts suggests that spaceflight may affect sensory perception and regulation, a finding similar to previous studies. Researchers recommend developing measurement tools with greater sensitivity and questions that capture previous spaceflight experience and astronaut status (commercial or professional) to assess pain experiences.

Astronauts frequently report pain during missions and after returning to Earth, particularly in the back and neck. Microgravity Pain Sensation (Ax-1) assessed how short-term exposure to microgravity affects pain sensation, biomechanics, bone physiology, and the musculoskeletal system. Results suggested that spaceflight may affect various aspects of sensory perception and regulation, and further investigation is needed to support development of countermeasures and treatments.

      Preparations for Next Moonwalk Simulations Underway (and Underwater)
      NASA’s EMIT collected this hyperspectral image of the Amazon River in northern Brazil on June 30 as part of an effort to map global ecosystem biodiversity. The instrument was originally tasked with mapping minerals over deserts; its data is now being used in research on a diverse range of topics. NASA/JPL-Caltech The imaging spectrometer measures the colors of light reflected from Earth’s surface to study fields such as agriculture, hydrology, and climate science.
      Observing our planet from the International Space Station since July 2022, NASA’s EMIT (Earth Surface Mineral Dust Source Investigation) mission is beginning its next act.
      At first the imaging spectrometer was solely aimed at mapping minerals over Earth’s desert regions to help determine the cooling and heating effects that dust can have on regional and global climate. The instrument soon added another skill: pinpointing greenhouse gas emission sources, including landfills and fossil fuel infrastructure.
      Following a mission extension this year, EMIT is now collecting data from regions beyond deserts, addressing topics as varied as agriculture, hydrology, and climate science.
      Imaging spectrometers like EMIT detect the light reflected from Earth, and they separate visible and infrared light into hundreds of wavelength bands — colors, essentially. Scientists use patterns of reflection and absorption at different wavelengths to determine the composition of what the instrument is observing. The approach echoes Isaac Newton’s prism experiments in 1672, in which the physicist discovered that visible light is composed of a rainbow of colors.
      Perched on the International Space Station, NASA’s EMIT can differentiate between types of vegetation to help researchers understand the distribution and traits of plant communities. The instrument collected this data over the mid-Atlantic U.S. on April 23.NASA/JPL-Caltech “Breakthroughs in optics, physics, and chemistry led to where we are today with this incredible instrument, providing data to help address pressing questions on our planet,” said Dana Chadwick, EMIT’s applications lead at NASA’s Jet Propulsion Laboratory in Southern California. 
      New Science Projects
      In its extended mission, EMIT’s data will be the focus of 16 new projects under NASA’s Research Opportunities in Space and Earth Science (ROSES) program, which funds science investigations at universities, research institutions, and NASA.
      For example, the U.S. Geological Survey (USGS) and the U.S. Department of Agriculture’s (USDA) Agricultural Research Service are exploring how EMIT can assess climate-smart agricultural practices. Those practices — winter cover crops and conservation tillage — involve protecting cropland during non-growing seasons with either living plants or dead plant matter to prevent erosion and manage nitrogen.
      Imaging spectrometers are capable of gathering data on the distribution and characteristics of plants and plant matter, based on the patterns of light they reflect. The information can help agricultural agencies incentivize farmers to use sustainable practices and potentially help farmers manage their fields. 
      “We’re adding more accuracy and reducing error on the measurements we are supplying to end users,” said Jyoti Jennewein, an Agricultural Research Service research physical scientist based in Fort Collins, Colorado, and a project co-lead.
      The USGS-USDA project is also informing analytical approaches for NASA’s future Surface Biology and Geology-Visible Shortwave Infrared mission. The satellite will cover Earth’s land and coasts more frequently than EMIT, with finer spatial resolution.
      Looking at Snowmelt
      Another new project will test whether EMIT data can help refine estimates of snowpack melting rates. Such an improvement could inform water management in states like California, where meltwater makes up the majority of the agricultural water supply.
      Imaging spectrometers like EMIT measure the albedo of snow — the percentage of solar radiation it’s reflecting. What isn’t reflected is absorbed, so the observations indicate how much energy snow is taking in, which in turn helps with estimates of snow melt rates. The instruments also discern what’s affecting albedo: snow-grain size, dust or soot contamination, or both.
      For this work, EMIT’s ability to measure beyond visible light is key. Ice is “pretty absorptive at near-infrared and the shortwave infrared wavelengths,” said Jeff Dozier, a University of California, Santa Barbara professor emeritus and the project’s principal investigator.
      Other ROSES-funded projects focus on wildflower blooming, phytoplankton and carbon dynamics in inland waters, ecosystem biodiversity, and functional traits of forests.
      Dust Impacts
      Researchers with EMIT will continue to study the climate effects of dust. When lofted into the air by windstorms, darker, iron-filled dust absorbs the Sun’s heat and warms the surrounding air, while lighter-colored, clay-rich particles do the opposite. Scientists have been uncertain whether airborne dust has overall cooling or warming effects on the planet. Before EMIT, they could only assume the color of particles in a region.
      The EMIT mission is “giving us lab-quality results, everywhere we need to know,” said Natalie Mahowald, the mission’s deputy principal investigator and an Earth system scientist at Cornell University in Ithaca, New York. Feeding the data into Earth system computer models, Mahowald expects to get closer to pinpointing dust’s climate impact as Earth warms.
      Greenhouse Gas Detection
      The mission will continue to identify point-source emissions of methane and carbon dioxide, the greenhouse gases most responsible for climate change, and observations are available through EMIT’s data portal and the U.S. Greenhouse Gas Center.
      The EMIT team is also refining the software that identifies and measures greenhouse-gas plumes in the data, and they’re working to streamline the process with machine-learning automation. Aligning with NASA’s open science initiative, they are sharing code with public, private, and nonprofit organizations doing similar work.
      “Making this work publicly accessible has fundamentally pushed the science of measuring point-source emissions forward and expanded the use of EMIT data,” said Andrew Thorpe, the JPL research technologist heading the EMIT greenhouse gas effort.
      More About EMIT
      The EMIT instrument was developed by NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech in Pasadena, California. Launched to the International Space Station in July 2022, EMIT is on an extended three-year mission in which it’s supporting a range of research projects. EMIT’s data products are available at the NASA Land Processes Distributed Active Archive Center for use by other researchers and the public.

      The Earth Observer Editor’s Corner: Fall 2024
      On September 18, 2024, the National Oceanic and Atmospheric Administration (NOAA) shared the first images of the Western Hemisphere from the GOES-19 satellite, its newest geostationary satellite launched on June 25, 2024 onboard a Falcon Heavy rocket from NASA’s Kennedy Space Center. Previously known as GOES-U, the satellite was renamed GOES-19 upon reaching geostationary orbit on July 7, 2024. GOES-19 orbits about 35,785 km above the equator at the same speed the Earth rotates, allowing the satellite to constantly view the same area of the planet and track weather conditions and hazards as they happen. The satellite’s Advanced Baseline Imager (ABI) instrument recently captured stunning views of Earth in 16 spectral channels. This data provides researchers information about Earth’s atmosphere, land, and ocean for short-term forecasts and tracking severe weather – see Figure. ABI data is also used for detecting and monitoring environmental hazards, such as wildfires, smoke, dust storms, volcanic eruptions, turbulence, and fog. Data from multiple ABI channels can be combined to create imagery that approximates what the human eye would see from space referred to as GeoColor (see Figure).
      Figure. [Left] The GOES-19 images show the contiguous U.S. observed by each of the Advanced Baseline Imager’s (ABI) 16 channels on August 30, 2024, at 6:00 PM UTC. This 16-panel image [progressing left to right, across each row] shows the ABI’s two visible (gray scale), four near-infrared (IR) (gray scale), and 10 infrared channels (warmer brightness temperatures of the IR bands map to warmer colors). Each band’s appearance illustrates how it reflects or absorbs radiation. [Right] The GOES-19 full disk GeoColor image combines data from multiple ABI channels to approximate what the human eye would see from space.  Figure Credit: NOAA GOES-19 is the final satellite in NOAA’s GOES-R series and serves as a bridge to a new age of advanced satellite technology. NOAA and NASA are currently developing NOAA’s next generation geostationary satellites, called Geostationary Extended Observations (GeoXO), to advance operational geostationary Earth observations.
      NASA Earth sciences celebrated several satellite milestone anniversaries in 2024. The Global Precipitation Measurement (GPM) Core Observatory (CO) celebrated its 10th anniversary in February while Aura and Orbiting Carbon Observatory–2 (OCO–2) celebrated their 20th and 10th anniversaries, respectively, in July. Here, we focus on GPM and Aura.
      The GPM CO launched on February 27, 2024, aboard a Japanese H-IIA rocket from Tanegashima Space Center in southern Japan, as a joint Earth-observing mission between NASA and the Japan Aerospace Exploration Agency (JAXA). To celebrate its 10th anniversary, GPM has been hosting special outreach activities. One example is the GPM 10-in-10 webinar series that began on February 8, 2024. This series of 10 public webinars explores GPM and the story behind the mission, which is aimed at anyone interested in science, technology, engineering, mathematics, and the synergy of these disciplines to better understand and protect our home planet.
      Now over 10 years into the mission, GPM continues to provide important data on precipitation around the globe leading to new scientific discoveries and contributing data to help society, from monitoring storms to supporting weather forecasts and aiding water-borne disease public health alerts.
      As an example, GPM made several passes of Hurricane Milton, which made landfall near Siesta Key, FL on October 9, 2024 as a Category 3 storm. As a complement to GPM CO observations, a multi-satellite sensor IMERG animation shows rainfall rates and accumulation over the course of Milton’s history.
      To read more about how GPM continues to observe important precipitation characteristics and gain physical insights into precipitation processes, please see the article “GPM Celebrates Ten Years of Observing Precipitation for Science and Society” in The Earth Observer.
      The last of NASA’s three EOS Flagships – Aura – marked 20 years in orbit on July 15, 2024, with a celebration on September 18, 2024, at Goddard Space Flight Center’s (GSFC) Recreational Center. The 120 attendees – including about 40 participating virtually – reminisced about Aura’s (originally named EOS-CHEM) tumultuous beginning, from the instrument and Principal Investigator (PI) selections up until the delayed launch at Vandenberg Space Force Base (then Air Force Base) in California. They remembered how Bill Townsend, who was Deputy Director of GSFC at the time, and Ghassem Asrar, who was NASA’s Associate Administrator for Earth Science, spent many hours on site negotiating with the Vandenberg and Boeing launch teams in preparation for launch (after several delays and aborts). Photo 1 shows the Aura mission program scientist, project scientists (PS), and several instrument principal investigators (PI) at Vandenberg shortly before launch.

Aura’s datasets have given a generation of scientists the most comprehensive global view of gases in Earth’s atmosphere to better understand the chemical and dynamic processes that shape their concentrations. Aura’s objective was to gather data to monitor Earth’s ozone layer, examine trends in global air pollutants, and measure the concentration of atmospheric constituents contributing to climate forcing.

      It has been over a year and a half since the Surface Water and Ocean Topography (SWOT) mission began collecting data on the height of nearly all water on Earth’s surface, including oceans, lakes, rivers, and reservoirs. During that time, data collected by the satellite has started to improve our understanding of energy in the ocean, yielding insights on surface currents and waves, internal tides, the vertical mixing of seawater, as well as atmosphere–ocean interactions. Notably, SWOT has been measuring the amplitude of solitary internal waves in the ocean. These waves reflect the dynamics of internal tides (tides that occur deep in the ocean rather than at the surface) that can influence biological productivity as well as ocean energy exchanges through their contribution to mixing and general oceanic circulation.
      SWOT measurements are also being used to study inland and coastal flooding to inform water management strategies. Earlier this year, researchers used SWOT data to measure the total volume of water during major floods in southern Brazil in April to improve understanding of these events and prepare for the future. In addition, the Water Ministry of Bangladesh is working to incorporate SWOT water elevation maps, along with other near-real time satellite data, into their flood forecasts. Researchers at Alexandria University, Egypt are using SWOT data in the Nile River Basin to improve dam operations. A detailed account of SWOT Significant Events since launch is available online. To learn more about project status and explore the many facets of operational and applied uses of SWOT data, please see The Earth Observer article, “Summary of the 10th SWOT Applications Workshop.”
      In September 2024, the Plankton, Aerosol, Cloud, ocean Ecosystem–Postlaunch Airborne eXperiment (PACE–PAX) gathered data for the validation of the PACE mission, which launched in February 2024.  The operations spanned Southern and Central California and nearby coastal regions, logging 81 flight hours for the NASA ER-2, which operated out of NASA’s Armstrong Flight Research Center (AFRC) in Edwards, CA, and 60 hours for Twin Otter aircraft, which was operated by the Center for Interdisciplinary Remotely Piloted Aircraft Studies (CIRPAS) at the Naval Postgraduate School (Monterey, CA) out of Marina Municipal Airport in Marina, CA – see Photo 2.

Shifting venues, NASA’s BlueFlux Campaign conducted a series of ground-based and airborne fieldwork missions out of the Miami Homestead Air Reserve Base and the Miami Executive Airport in Miami-Dade County, which are adjacent to the eastern border of the Everglades National Park. The full study region – broadly referred to as South Florida – is narrowly defined by the wetland ecosystems that extend from Lake Okeechobee and its Northern estuaries to the saltwater marshland and mangrove forests along the state’s southernmost shore. 
      Glenn Wolfe [GSFC] and Erin Delaria [GSFC/UMD] organized more than 34 flights across 5 separate fieldwork deployments during the campaign. The data during BlueFlux are intended to contribute to a more robust understanding of how Florida’s coastal ecology fits into the carbon cycle.  The article, “NASA’s BlueFlux Campaign Supports Blue Carbon Management in South Florida,” provides additional information about this program, which was made possible by David Lagomasino [East Carolina University], Cheryl Doughty [GSFC/UMD], Lola Fatoyinbo [GSFC], and Peter Raymond [Yale University].

      Notable recent Science Support Office (SSO) outreach activities include the 2024 Eclipse outreach and engagement efforts on April 7, 2024, in Kerrville, TX and Cleveland, OH. The two locations are among a dozen that NASA set up along path of totality. To read about the 2024 Total Solar Eclipse through the eyes of NASA outreach and engagement activities, please see The Earth Observer feature article, “Looking Back on Looking Up: The 2024 Total Solar Eclipse.”
      The SSO also supported the United Nations (UN) Summit of the Future event and the 79th General Assembly High Level week, September 19–27, 2024 at UN Headquarters (HQ) in New York City, NY. SSO supported the NASA Sea Level Change Team (N-SLCT) during the High-level Meeting on Sea-Level Rise by having Hyperwall content available for the release of the new Pacific Flooding Analysis Tool. NASA Administrator Bill Nelson visited the Hyperwall on September 23 with Aarti Holla-Maini [UN Office for Outer Space Affairs (UNOOSA)—Director]. Karen St. Germain [NASA HQ—Director of the Earth Science Division], Julie Robinson [NASA HQ—Deputy Director of the Earth Science Division], Kate Calvin [NASA HQ—NASA Chief Scientist], Lesley Ott [GSFC— Climate Scientist], and Anjali Tripathi [NASA/Jet Propulsion Laboratory (JPL)—Astrophysicist] talked with delegates and members about NASA Science and accessed NASA global datasets. Photos from the event are available at the SSO Flickr Page.
      Looking ahead, the SSO is once again leading the planning and logistics for the NASA exhibit at the American Geophysical Union (AGU) Fall Meeting, which will be held December 9–13, 2024 in Washington, DC. Nearly 40 NASA projects and missions will have hands-on activities within the perimeter of the NASA Science exhibit, from the James Webb Space Telescope to the Airborne Science Fleet. The NASA Hyperwall, a video wall used for visual-forward science storytelling, will host approximately 50 Hyperwall stories and presentations throughout the meeting, including presentations delivered by the 2024 winners of the NASA-funded AGU Michael H. Freilich Student Visualization Competition. The exhibit will also feature roughly 40 tech demonstrations throughout the week, covering a wide range of hands-on introductions to everything from the capabilities of the OpenSpace data visualization software to the scientific applications of augmented reality. Please be sure to stop by the NASA exhibit when you are at AGU.

      5 Min Read Wearable Tech for Space Station Research
      A wearable monitoring device is visible on the left wrist of NASA astronaut Jeanette Epps. Credits: NASA Science in Space Nov 2024
      Many of us wear devices that count our steps, measure our heart rate, track sleep patterns, and more. This information can help us make healthy decisions – research shows the devices encourage people to move more, for example – and could flag possible problems, such as an irregular heartbeat.
      Wearable monitors also have become common tools for research on human health, including studies on the International Space Station. Astronauts have worn special watches, headbands, vests, and other devices to help scientists examine sleep quality, effectiveness of exercise, heart health, and more.
      Warm to the core
      Spaceflight can affect body temperature regulation and daily rhythms due to factors such as the absence of convection (a natural process that transfers heat away from the body) and changes in the cardiovascular and metabolic systems.
      A current investigation from ESA (European Space Agency), Thermo-Mini or T-Mini examines how the body regulates its core temperature during spaceflight. The study uses a non-invasive headband monitor that astronauts can wear for hours at a time. Data from the monitor allow researchers to determine the effect on body temperature from environmental and physiological factors such as room temperature and humidity, time of day, and physical stress. The same type of sensor already is used on Earth for research in clinical environments, such as improving incubators, and studies of how hotter environments affect human health.
      Thermolab, an earlier ESA investigation, examined thermoregulatory and cardiovascular adaptations during rest and exercise in microgravity. Researchers found that core body temperature rises higher and faster during exercise in space than on Earth and that the increase was sustained during rest, a phenomenon that could affect the health of crew members on long-term spaceflight. The finding also raises questions about the thermoregulatory set point humans are assumed to have as well as our ability to adapt to climate change on Earth.
      NASA astronaut Nick Hague wears the T-mini device while exercising.NASA To sleep, perchance to dream
      Spaceflight is known to disrupt sleep-wake patterns. Actiwatch Spectrum, a device worn on the wrist, contains an accelerometer to measure motion and photodetectors to monitor ambient lighting. It is an upgrade of previous technology used on the space station to monitor the length and quality of crew member sleep. Data from earlier missions show that crew members slept significantly less during spaceflight than before and after. The Actiwatch Sleep-Long investigation used an earlier version of the device to examine how ambient light affects the sleep-wake cycle and found an association between sleep deficiency and changes during spaceflight in circadian patterns, or the body’s response to a normal 24-hour light and dark cycle. Follow up studies are testing lighting systems to address these effects and help astronauts maintain healthy circadian rhythms.
      NASA astronaut Sunita Williams wears an Actiwatch as she conducts research.NASA Wearable Monitoring tested a lightweight vest with embedded sensors to monitor heart rate and breathing patterns during sleep and help determine whether changes in heart activity affect sleep quality. The technology offers a significant advantage by monitoring heart activity without waking the test subject and could help patients on Earth with sleep disorders. Researchers reported positive performance and good quality of recorded signals, suggesting that the vest can contribute to comprehensive monitoring of individual health on future spaceflight and in some settings on Earth as well.
      These and other studies support development of countermeasures to improve sleep for crew members, helping to maintain alertness and lessen fatigue during missions.
      (Not) waiting to exhale
      Humans exhale carbon dioxide and too much of it can build up in closed environments, causing headaches, dizziness, and other symptoms. Spacecraft have systems to remove this substance from cabin air, but pockets of carbon dioxide can form and be difficult to detect and remove. Personal CO2 Monitor tested specially designed sensors attached to clothing to monitor the wearer’s immediate surroundings. Researchers reported that the devices functioned adequately as either crew-worn or static monitors, an important step toward using them to determine how carbon dioxide behaves in enclosed systems like spacecraft.
      One of the wearable carbon dioxide monitors clipped to the wall near a crew sleeping compartment. Radiation in real time
      EVARM, an investigation from CSA (Canadian Space Agency), used small wireless dosimeters carried in a pocket to measure radiation exposure during spacewalks. The data showed that this method is a feasible way to measure radiation exposure, which could help focus routine dosage monitoring where it is most needed. Any shielding and countermeasures developed also could help protect people who work in high-radiation areas on Earth.
      ESA’s Active Dosimeter tested a radiation dosimeter worn by crew members to measure changes in their exposure over time based on the space station’s orbit and altitude, the solar cycle, and solar flares. Measurements from the device allowed researchers to analyze radiation dosage across an entire space mission.
      ESA astronaut Thomas Pesquet holds one of the mobile units for the Active Dosimeter study.NASA The Active Dosimeter also was among the instruments used to measure radiation on NASA’s Orion spacecraft during its 25.5-day uncrewed Artemis I mission around the Moon and back in 2022.
      Another device tested on the space station and then on Artemis I, AstroRad Vest is designed to protect astronauts from solar particle events. Researchers used these and other radiation measuring devices to show that Orion’s design can protect its crew from potentially hazardous radiation levels during lunar missions.
      The International Space Station serves as an important testbed for these technologies and many others being developed for future missions to the Moon and beyond.

Students are building CubeSat emulators to launch on high-altitude balloons, and their work will drive their questions with crew.
      Media interested in covering the event must RSVP by 5 p.m., Wednesday, Nov. 13, to Daniela Di Napoli at: daniela.dinapoli@scienceandtech.org or 832-656-5231.
      For more than 24 years, astronauts have continuously lived and worked aboard the space station, testing technologies, performing science, and developing skills needed to explore farther from Earth. Astronauts aboard the orbiting laboratory communicate with NASA’s Mission Control Center in Houston 24 hours a day through SCaN’s (Space Communications and Navigation) Near Space Network.
      Important research and technology investigations taking place aboard the space station benefit people on Earth and lays the groundwork for other agency missions. As part of NASA’s Artemis campaign, the agency will send astronauts to the Moon to prepare for future human exploration of Mars; inspiring Artemis Generation explorers and ensuring the United States continues to lead in space exploration and discovery.

      NASA/Loral O’Hara The Choctaw Heirloom Seeds investigation flew five varieties of heirloom seeds from the Choctaw Nation of Oklahoma aboard the International Space Station in early November 2023. The seeds are Isito (Choctaw Sweet Potato Squash), Tobi (Smith Peas), Tanchi Tohbi (Flour Corn), Tvnishi (Lambsquarter), and Chukfi Peas. The seeds spent six months aboard station, returning to Earth in April 2024.
      Next spring, Jones Academy students will plant the space-flown seeds alongside Earth-bound seeds of the same type in the school’s Growing Hope Garden. Students will hypothesize how the seeds will grow and make observations throughout the growing season.
      Middle school teachers are developing curriculum incorporating the seeds’ journey to space station and students’ experiments in the garden. This research could impact Native and Indigenous populations across the United States, inviting underrepresented groups to engage with science, technology, engineering, and mathematics.
