NASA has selected 12 new investigations to help support human explorers in space. Six will help advance the ability to produce food off-planet, while another six advance the understanding of how unique conditions associated with space exploration can impact the health and physiology of astronauts.
The six food-focused investigations, supported by the agency’s Space Crops grants, advance NASA’s goal of harnessing the power of plants to enhance quality of life for humans in space, as well as to enable lunar and Mars exploration. Four of the space crops proposals focus on studies of edible plants and how their growth, physiology, and associated microbial communities are affected by environmental conditions in space or on other planetary bodies.
Another proposal involves understanding mechanisms by which certain plant species, called resurrection plants, can withstand extreme, dry conditions. The last space crops proposal builds on previous studies on the International Space Station to uncover functions of algal genes, segments of DNA controlling algae survival, whose expression is modified by spaceflight. Such studies can help scientists integrate biological-based solutions into space life-support systems.
The second set of six proposals fall under the agency’s Biological and Physical Sciences Division’s focus on precision health, which seeks to unravel the mechanisms by which space exploration affects health and well-being. One proposal studies how lunar dust exposure impacts respiratory, immune, and inflammation responses. A second proposal identifies repurposed drugs that can mitigate the effects space travel has on health and physiology.
Two more of the research proposals look at how radiation combined with other stressors affects age-relevant characteristics seen in various organ and physiological systems. The final two proposals assess molecular and cellular changes induced by stressors in space that can alter gene expression or protein function. The research will identify ways to mitigate health issues and develop early-warning detection systems to notify crew of potential concerns.
The principal investigators who conduct the space biology studies come from 10 institutions across eight states. Nine of the awards are for investigators who are receiving funding from the Space Biology Program for the first time.

Biological & Physical Sciences Division
NASA’s Biological and Physical Sciences Division pioneers scientific discovery and enables exploration by using space environments to conduct investigations not possible on Earth. Studying biological and physical phenomenon under extreme conditions allows researchers to advance the fundamental scientific knowledge required to go farther and stay longer in space, while also benefitting life on Earth.
