How to Garden in Space
If humans are to become a space-fairing species (as many have argued the need for), there are many problems to solve: biology in zero-gravity, energy consumption, water recycling, and food (to name a few). The primary goal of the International Space Station is to solve these problems for long-duration space flight. In their latest video, the Science Mission Directorate at NASA takes a look at what we've learned about growing food in space so far.
