Space Salad

Standard

Most science fiction notions of humans living in space, at least the ones that aren’t all white-walled and minimalistic, involve at least one image something like this:

NASA announced that later this year, the International Space Station will, for the first time, practice space farming. Six heads of romaine lettuce, to be exact, grown in Kevlar pillow packs filled with something like kitty litter.

From the ISS web site: “The Vegetable Production System (Veggie) is a deployable plant growth unit capable of producing salad-type crops to provide the crew with a palatable, nutritious, and safe source of fresh food and a tool to support relaxation and recreation.”

So, something a little more modest. Like this:

Success with lettuce (or lessons learned) could even lead to radishes, snap peas, and a strain of tomato bred for modest space (!) requirements.

I especially like that one of the benefits defined for space gardening, beyond the more sterile standards of ‘nutrition’ and ‘safe food source’ is the more ephemeral potential for ‘relaxation‘. Assuming, of course, that the astronauts doing the tending actually like to garden.

Even though the gardening will be done in a tiny enclosed living area with limited water and soil, I’m pretty sure this doesn’t yet count as urban gardening.
