Green Plants for Mars Mission
An anonymous reader writes "NASA doesn't keep back that they are going to send a human expedition to Mars in a couple of decades. One of the obstacles for the longstanding 35-million-mile voyage is a food production. NASA researchers have focused on 20 plant species that NASA believes could be grown during a flight to Mars and after landing on the fourth planet from the Sun. By far not all of them are suitable for space expedition."
Why can't they just make a spacecraft that has a rotating section to provide artifical gravity, so they wouldn't have to worry about cultivating plants in 0-G?
Hmmm whats the bet marijuana is an excellent growing planet in space but... you know..
can't get high when your THAT high.
