(NASA Ames Research Center) Title: Growing the first plants on Mars and the Moon Abstract: In the next decades, humans will have a colony of astronauts on the surface of Mars for extended periods of time . One critical aspect to be developed in advance is how these astronauts will obtain their food in this new environment. Here we show our preliminary advances in an initiative to send a small greenhouse to Mars and the Moon in order to attain the first germination of seeds and initial growth of platelets in an extraterrestrial environment.
