NASA Selects Two Teams to Advance Life Sciences Research in Space
NASA announced two awards Thursday to establish scientific consortia – multi-institutional coalitions to conduct ground-based studies that help address the agency’s goals of maintaining a sustained human presence in space. These consortia will focus on biological systems research in the areas of animal and human models, plants, and microbiology. When fully implemented, the awards for these consortia will total about $5 million.
Space biology efforts at NASA use the unique environment of space to conduct experiments impossible to do on Earth. Such research not only supports the health and welfare of astronauts, but results in breakthroughs on diseases such as cancer and neurodegenerative disorders to help protect humanity down on the ground.
The awards for the two consortia are for the following areas:
Studying space biosphere. The Biology in Space: Establishing Networks for DUrable & REsilient Systems consortium involves a collaborative effort between human/animal, plant, and microbial biologists to ensure an integrated view of the space flight biosphere by enhancing data acquisition, modeling, and testing. It will include participation of more than thirty scientists and professionals working together from at least three institutions. Led by Kristi Morgansen at the University of Washington in Seattle, Washington. Converting human waste into materials for in-space biomanufacturing. The Integrative Anaerobic Digestion and Phototrophic Biosystem for Sustainable Space Habitats and Life Supports consortium will develop an anaerobic digestion process that converts human waste into organic acids and materials that can be used for downstream biomanufacturing applications in space. It will include eight scientists from six different institutions in three different states, including Delaware and Florida. The consortium is led by Yinjie Tang at Washington University in St. Louis, Missouri. Proposals for these consortia were submitted in response to ROSES 2024 Program Element E.11 Consortium in Biological Sciences for a consortium with biological sciences expertise to carry out research investigations and conduct activities that address NASA’s established interests in space life sciences.
NASA’s Space Biology Program within the agency’s Biological and Physical Sciences division conducts research across a wide spectrum of biological organization and model systems to probe underlying mechanisms by which organisms acclimate to stressors encountered during space exploration (including microgravity, ionizing radiation, and elevated concentrations of carbon dioxide). This research informs how biological systems regulate and sustain growth, metabolism, reproduction, and development in space and how they repair damage and protect themselves from infection and disease.

Preparations for Next Moonwalk Simulations Underway (and Underwater)
This artist’s concept depicts a potential volcanic moon between the exoplanet WASP-49 b, left, and its parent star. New evidence indicating that a massive sodium cloud observed near WASP-49 b is produced by neither the planet nor the star has prompted researchers to ask if its origin could be an exomoon.NASA/JPL-Caltech The existence of a moon located outside our solar system has never been confirmed but a new NASA-led study may provide indirect evidence for one.
New research done at NASA’s Jet Propulsion Laboratory reveals potential signs of a rocky, volcanic moon orbiting an exoplanet 635 light-years from Earth. The biggest clue is a sodium cloud that the findings suggest is close to but slightly out of sync with the exoplanet, a Saturn-size gas giant named WASP-49 b, although additional research is needed to confirm the cloud’s behavior. Within our solar system, gas emissions from Jupiter’s volcanic moon Io create a similar phenomenon.
Although no exomoons (moons of planets outside our solar system) have been confirmed, multiple candidates have been identified. It’s likely these planetary companions have gone undetected because they are too small and dim for current telescopes to detect.
The sodium cloud around WASP-49 b was first detected in 2017, catching the attention of Apurva Oza, formerly a postdoctoral researcher at NASA’s Jet Propulsion Laboratory and now a staff scientist at Caltech, which manages JPL. Oza has spent years investigating how exomoons might be detected via their volcanic activity. For example, Io, the most volcanic body in our solar system, constantly spews sulfur dioxide, sodium, potassium, and other gases that can form vast clouds around Jupiter up to 1,000 times the giant planet’s radius. It’s possible that astronomers looking at another star system could detect a gas cloud like Io’s even if the moon itself were too small to see.
Exomoons — moons around planets outside our solar system — are most likely too small to observe directly with current technology. In this video, learn how scientists tracked the motion of a sodium cloud 635 light-years away and found that it could be created by volcanos on a potential exomoon. NASA/JPL-Caltech Both WASP-49 b and its star are composed mostly of hydrogen and helium, with trace amounts of sodium. Neither contains enough sodium to account for the cloud, which appears to be coming from a source that is producing roughly 220,000 pounds (100,000 kilograms) of sodium per second. Even if the star or planet could produce that much sodium, it’s unclear what mechanism could eject it into space.
Could the source be a volcanic exomoon? Oza and his colleagues set out to try to answer that question. The work immediately proved challenging because from such a great distance, the star, planet, and cloud often overlap and occupy the same tiny, faraway point in space. So the team had to watch the system over time.
A Cloud on the Move
As detailed in a new study published in the Astrophysical Journal Letters, they found several pieces of evidence that suggest the cloud is created by a separate body orbiting the planet, though additional research is needed to confirm the cloud’s behavior. For example, twice their observations indicated the cloud suddenly increased in size, as if being refueled, when it was not next to the planet.
New NASA-led research suggests a sodium cloud seen around the exoplanet WASP-49 b might be created by a volcanic moon, which is depicted in this artist’s concept. Jupiter’s fiery moon Io produces a similar cloud. NASA/JPL-Caltech They also observed the cloud moving faster than the planet in a way that would seem impossible unless it was being generated by another body moving independent of, and faster, than the planet.
“We think this is a really critical piece of evidence,” said Oza. “The cloud is moving in the opposite direction that physics tells us it should be going if it were part of the planet’s atmosphere.”
While these observations have intrigued the research team, they say they would need to observe the system for longer to be sure of the cloud’s orbit and structure.
A Chance of Volcanic Clouds
For part of their sleuthing, the researchers used the European Southern Observatory’s Very Large Telescope in Chile. Oza’s co-author Julia Seidel, a research fellow at the observatory, established that the cloud is located high above the planet’s atmosphere, much like the cloud of gas Io produces around Jupiter.
They also used a computer model to illustrate the exomoon scenario and compare it to the data. The exoplanet WASP-49 b orbits the star every 2.8 days with clocklike regularity, but the cloud appeared and disappeared behind the star or behind the planet at seemingly irregular intervals. Using their model, Oza and team showed that a moon with an eight-hour orbit around the planet could explain the cloud’s motion and activity, including the way it sometimes seemed to move in front of the planet and did not seem to be associated with a particular region of the planet.
“The evidence is very compelling that something other than the planet and star are producing this cloud,” said Rosaly Lopes, a planetary geologist at JPL who co-authored the study with Oza. “Detecting an exomoon would be quite extraordinary, and because of Io, we know that a volcanic exomoon is possible.”
A Violent End
On Earth, volcanoes are driven by heat in its core left over from the planet’s formation. Io’s volcanoes, on the other hand, are driven by Jupiter’s gravity, which squeezes the moon as it gets closer to the planet then reduces its “grip” as the moon moves away. This flexing heats the small moon’s interior, leading to a process called tidal volcanism.
If WASP-49 b has a moon similar in size to Earth’s, Oza and team estimate that the rapid loss of mass combined with the squeezing from the planet’s gravity will eventually cause it to disintegrate.
“If there really is a moon there, it will have a very destructive ending,” said Oza.

Culturally Inclusive Planetary Engagement in Colorado
In August 2024, the NASA Science Activation program’s Planetary Resources and Content Heroes (ReaCH) project held a Culturally Inclusive Planetary Engagement workshop at the Laboratory for Atmospheric and Space Physics in Boulder, Colorado for the planetary science community. These workshops are designed to enhance the ability of scientists to engage Black and Latinx youth and their families in planetary science. Workshops include discussions with local educators about evidence-based engagement strategies and experiences conducting hands-on planetary science activities, along with an opportunity to practice these approaches during an event with local partners.
Planetary scientists and engineers from Boulder, as well as scientists from Florida, Maryland, and Alaska participated. ReaCH partnered with the Boys & Girls Clubs of Metro Denver, whose staff participated in the workshop to share their perspectives. Other educators local to the Denver area also participated, along with an educational specialist from NASA@ My Library (another Science Activation program). The workshop culminated in an event at the Shopneck Boys & Girls Club in Brighton, CO; workshop participants facilitated a variety of hands-on planetary activities for approximately 120 children. Workshop participants also shared information about college pathways into science professions with teenagers at the Club.
During feedback with evaluators, workshop participants shared, “I got to have hands-on experience working with an underserved population, which I haven’t done before in a workshop. I think this is the necessary next step for me. I am tired of just learning about things. I want to DO things. This gave me the ability to do it without setting up everything myself.”
Through careful revisions to these workshops and detailed evaluation, the Planetary ReaCH project is building a replicable model that will be used to support similar workshops for other science fields. Members of the planetary and astrobiology community are invited to apply to attend future ReaCH workshops.
Planetary ReaCH is supported by NASA under cooperative agreement award number 80NSSC21M0003 and is part of NASA’s Science Activation Portfolio.
