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.

A salute is widely recognized as a display of respect, but did you know it also means ‘hello’ in American Sign Language?
It is one of the signs that Jesse Bazley, International Space Station/Commercial Low Earth Orbit Development Program integration team lead, subtly incorporates into his daily interactions with colleagues at NASA’s Johnson Space Center in Houston.
In May 2021, Jesse Bazley worked his final shift as an Environmental and Thermal Operating Systems flight controller in the Mission Control Center at NASA’s Johnson Space Center in Houston. Image courtesy of Jesse Bazley Bazley is hard of hearing, which has at times presented challenges in his daily work – particularly during his stint as an Environmental and Thermal Operating Systems flight controller for the space station. “Working on console [in the Mission Control Center], you must listen to dozens of voice loops at a time, sometimes in different languages,” he said, adding that the standard-issue headset for flight controllers was not compatible with his hearing aids. Bazley adapted by obtaining a headset that fit over his hearing aids, learning how to adjust the audio system’s volume, and limiting over-the-air discussions when possible.
Bazley has been part of the NASA team for 17 years, filling a variety of roles that support the International Space Station. One of his proudest achievements occurred early in his tenure. Bazley was an intern at Marshall Space Flight Center in Huntsville, Alabama, in 2006 when the space station’s Water Recovery System was being tested. The system converts the station’s wastewater into drinkable water for the crew. When he arrived at Johnson one year later, his first assignment was to assist with the system’s procedure and display development for its incorporation into the space station’s core operations. “Now, 16 years later, it is commonplace for the space station to ‘turn yesterday’s coffee into tomorrow’s coffee’,” he said.
Jesse Bazley supporting the Atmosphere and Consumables Engineer console during the STS-127 mission in July 2009. NASA His favorite project so far has been integrating the station’s Thermal Amine Scrubber – which removes carbon dioxide from the air – into station operations. “I worked it from the beginning of NASA’s involvement, helping the provider with software testing and the integration of a brand-new Mission Control Center communications architecture,” he said.
Today, Bazley works to integrate subject matter experts from Johnson’s Flight Operations Directorate (FOD) into the processes of the International Space Station and Commercial Low Earth Orbit Development Programs. “I help pull together FOD positions on topics and coordinate reviews of provider materials to ensure that the operations perspective is maintained as development moves forward,” he explained.
While Bazley no longer supports a console, he must continue adapting to difficult hearing environments. He uses the captioning tools available through videoconferencing software during frequent team meetings, for example. “It’s important to understand that people have visible and invisible disabilities,” he said. “Sometimes their request for a remote option is not because they want to avoid an in-person meeting. It may be that they work best using the features available in that virtual environment.”
Bazley also chairs the No Boundaries Employee Resource Group, which promotes the development, inclusion, and innovation of Johnson’s workforce with a focus on employees with disabilities and employees who are caregivers of family members with disabilities.
From these diverse roles and experiences, Bazley has learned to listen to his gut instincts. “In flight operations, you must work with short timelines when things happen in-orbit, so you have to trust your training,” he said. “Understanding when you have enough information to proceed is critical to getting things done.”
Bazley looks forward to the further commercialization of low Earth orbit so NASA can focus resources on journeying to the Moon and Mars. “Aviation started out as government-funded and now is commonplace for the public. I look forward to seeing how that evolution progresses in low Earth orbit.”
His advice to the Artemis Generation is to consider the long-term impact of their actions and decisions. “What looks great on paper may not be a great solution when you have to send 10 commands just to do one task, or when the crew has to put their hand deep into the spacecraft to actuate a manual override,” he said. “The decisions you make today will be felt by operations in the future.”

Preparations for Next Moonwalk Simulations Underway (and Underwater)
Science in Space: October 2024
Cultures around the world celebrate Halloween on Oct 31. In many places, in addition to people wearing costumes and eating candy, this day is associated with spooky decorating using fake blood, skeletons, flies, and spiders, some of them glow-in-the-dark.
Crew members on the International Space Station have been known to indulge in a bit of dressing up and candy consumption to mark the day, and the research they conduct year-round occasionally involves these iconic Halloween themes. No tricks, just treats.
JAXA astronaut Koichi Wakata and NASA astronauts Frank Rubio, Nicole Mann, and Josh Cassada dressed up for Halloween 2022.NASA A current investigation, Megakaryocytes Flying-One or MeF1, investigates how components of real blood known as megakaryocytes and platelets develop and function during spaceflight. Megakaryocytes are large cells found in bone marrow and platelets are pieces of these cells. Both play important roles in blood clotting and immune response. Results could improve understanding of changes in inflammation, immune responses, and clot formation in spaceflight and on the ground.
Creepy crawlies
Fake spiders and flies are popular Halloween decorations (and fodder for fun pranks). Several investigations on the space station have used real ones.
Fruit Fly Lab-02 used fruit flies, Drosophila melanogaster, to examine the cellular and genetic mechanisms that affect heart health during spaceflight. The flies experienced several effects on cardiac function, including changes in muscle fibers, that could be a fundamental response of heart muscles to microgravity.
MVP Fly-01 looked at how spaceflight affects immune function and resulting changes to the nervous system of the same type of flies, along with the value of artificial gravity as a countermeasure. Researchers found that artificial gravity provided some protection to physical changes to the central nervous system from spaceflight. Spiders, Fruit Flies and Directional Plant Growth (CSI-05) compared the weaving characteristics of golden orb-web spiders on the space station and the ground. Under natural conditions, the spiders build asymmetric webs with the hub near the upper edge, where they wait for prey. In microgravity, most but not all webs were quite symmetric, although webs built when the lights were on were more asymmetric and the spiders waited facing away from the lights. This could mean that in the absence of gravity, the spiders orient to the direction of light.

Everyone needs healthy bones and skeletons, and not just on Halloween. But spaceflight and aging on Earth can cause loss of bone mass. Space station research has looked at the mechanisms behind this loss as well as countermeasures such as exercise and nutrition.
Bisphosphonates as a Countermeasure to Bone Loss examined whether a medication that blocks the breakdown of bone, in conjunction with the routine in-flight exercise program, protected crew members from bone mineral density loss during spaceflight. The research found that it did reduce loss, which in turn reduced the occurrence of kidney stones in crew members.
Assessment of the Effect of Space Flight on Bone (TBone) studied how spaceflight affects bone quality using a high-resolution bone scan technique. Researchers found incomplete recovery of bone strength and density in the tibia (a bone in the lower leg), comparable to a decade or more of terrestrial age-related bone loss. The work also highlighted the relationship between length of a mission and bone loss and suggested that pre-flight markers could identify crew members at greatest risk.
In a merging of blood and bones, CSA’s Marrow looked at whether microgravity has a negative effect on bone marrow and the blood cells it produces. Decreased production of red blood cells can lead to a condition called space anemia. Findings related to the expression of genes involved in red blood cell formation and those related to bone marrow adipose or fat tissue, which stores energy and plays a role in immune function, could contribute to development of countermeasures. Marrow results also suggested that the destruction of red blood cells (known as hemolysis) is a primary effect of spaceflight and contributes to anemia. Bad news for vampires.

Fluorescence – a cool effect at a ghoulish party – also is a common tool in scientific research, enabling researchers to see physical and genetic changes. The space station has special microscopes for observing glow-in-the-dark samples.
For Medaka Osteoclast 2, an investigation from JAXA (Japan Aerospace Exploration Agency), researchers genetically modified translucent Medaka fish with fluorescent proteins to help them observe cellular and genetic changes the fish experience during spaceflight. One analysis revealed a decrease in the mineral density of bones in the throat and provided insights into the mechanisms behind these changes.

This result suggests that microbial-supported bioproduction and life support systems can perform in reduced gravity such as that on Mars, which would be a perfect place for an epic Halloween celebration.
