Part 5/7:
While current capabilities suffice for the International Space Station, the Mars mission demands novel solutions. A critical concern is vitamin degradation, especially with nutrients like vitamin C, which can cause deficiencies such as scurvy if not properly managed. Growing crops on Mars could supplement stored food, but relying solely on extraterrestrial farming introduces uncertainties.
NASA recognizes that developing a robust food system capable of supporting a crew for five years requires extensive research, validation, and contingency planning. If crop production doesn't meet expectations, extra stored food will be essential to bridge gaps while troubleshooting.
