The Planetary Society’s Science and Technology Empowered by the Public (STEP) Grants present funding to innovation initiatives that advance house science and exploration. The 2023 spherical of STEP Grants awarded $50,000 USD to a crew led by Dr. Andrew Palmer of the Florida Institute of Technology to check deep-space agriculture to handle the problem of feeding astronauts on long-duration missions.
“The Planetary Society’s funding has been transformative in a variety of ways,” mentioned Palmer. “It has fueled science, created new projects, and helped strengthen the space agriculture network.” The crew has revealed three scientific papers primarily based on the analysis enabled by the grant, with one other two to 3 anticipated this yr.
The foremost aim of the CHRGE (Comparing Hydroponics and Regolith Growth and Evolution) venture was to check plant development in lunar regolith simulant versus hydroponic programs. Measuring development throughout a number of generations of crops, the crew has collected complete knowledge on metrics like edible biomass yields in addition to sensible issues like water utilization, energy necessities, and crew time. They are additionally working to enhance the event of Martian regolith simulants, testing numerous components that may have an effect on plant development.
