CAPE CANAVERAL, Fla. - Inside the Space Life Sciences Laboratory, or SLSL, at NASAs Kennedy Space Center in Florida, radish plants are being harvested in a plant growth chamber. The plants were grown under red and blue LED lights.The plant experiment at Kennedy is part of the Advanced Exploration Systems, or AES, program in NASAs Human Exploration and Operations Mission Directorate. This plant experiment studies the effects of different types of lighting on plants such as radishes and leaf lettuce. Results of these studies will help provide information on how to grow food sources for deep space exploration missions. AES projects pioneer new approaches for rapidly developing prototype systems, demonstrating key capabilities and validating operational concepts for future human missions beyond Earth orbit.
