NASA Selects 12 Space Biology Research Studies

NASA announces the award of 12 grants or cooperative agreements for exciting new space biology research that will advance NASA’s understanding of how vertebrate and invertebrate model organisms respond, acclimate, and adapt to the space environment in support of human space exploration. Proposals for these projects were submitted in response to ROSES-2021 Program Element E.11 “Space Biology: Animal Studies” (NNH21ZDA001N-SBAS).

As human exploration prepares to go beyond Low Earth Orbit, NASA’s Biological and Physical Sciences Division (BPS) is shifting its research priorities towards work that will enable organisms to Thrive In DEep Space (TIDES). These efforts will focus on determining the effects of multiple deep-space stressors, including deep space radiation and reduced gravity on multiple animal models.

Selected studies involve, but are not limited to, efforts to 1) characterize the ability of dietary countermeasures to mitigate the negative effects of radiation exposure in mammals, 2) determine how exposure to various types of space-relevant radiation affects cognitive and neurological function, and 3) how exposure to simulated levels of fractional and hyper-gravity impact animal physiology.

The selection of these awards was made possible through a collaboration between BPS and the Space Radiation Element of the NASA Human Research Program, which will provide access to the NASA Space Radiation Laboratory at Brookhaven National Laboratory for many of the awarded studies.

Twelve investigators from eight institutions in seven states will conduct these space biology investigations. Six of these awards are to investigators new to the Space Biology Program within BPS. When fully implemented, about $3.55 million will be awarded in fiscal years 2023-2026.
