Researchers found that radishes, lettuce and wheat can be exposed to vacuum conditions for half an hour with no ill effects. We salute the brave souls who sacrificed themselves for science . . . and ate space radishes.
Space colonization has been a dream of humanity for many years. Despite Nasa budget cuts, a lost spacecraft or two, and evidence that it's going to be impossible to successfully boink in space, some hardy souls just keep preparing to make that dream a reality.

Seeds can be germinated in space, but to grow they'd special pressurized greenhouses set up for them. If those greenhouses sprung a leak and depressurized, would an entire colony starve?
