What do you do next when you’ve successfully screwed up the Earth? Screw up Space too! Agricultural science is approaching its next frontier reports Modern Farmer:
Last year, an astronaut named Don Pettit began an unusual writing project on NASA’s website. Called “Diary of a Space Zucchini,” the blog took the perspective of an actual zucchini plant on the International Space Station (ISS). Entries were insightful and strange, poignant and poetic.
“I sprouted, thrust into this world without anyone consulting me,” wrote Pettit in the now-defunct blog. “I am utilitarian, hearty vegetative matter that can thrive under harsh conditions. I am zucchini — and I am in space.”
An unorthodox use of our tax dollars, but before you snicker, consider this: That little plant could be the key to our future. If — as some doomsday scientists predict — we will eventually exhaust the Earth’s livability, space farming will prove vital to the survival of our species. Around the world, governments and private companies are doing research on how we are going to grow food on space stations, in spaceships, even on Mars. The Mars Society is testing a greenhouse in a remote corner of Utah, researchers at the University of Gelph in Ontario are looking at long-term crops like soybeans and barley and Purdue University scientists are marshaling vertical garden design for space conditions. Perhaps most importantly, though, later this year NASA will be producing its own food in orbit for the first time ever.
And if space farming still seems like a pipe dream, the zucchini also served a more tangible purpose. It kept Pettit and his crewmates sane.
You Can Eat It, Too
Growing food in space helps solve one of the biggest issues in space travel: the price of eating. It costs roughly $10,000 a pound to send food to the ISS, according to Howard Levine, project scientist for NASA’s International Space Station and Spacecraft Processing Directorate. There’s a premium on densely caloric foods with long shelf lives. Supply shuttles carry such limited fresh produce that Gioia Massa, a postdoctoral fellow at NASA, says astronauts devour it almost immediately.
Levine and Massa are part of the team developing the Vegetable Production System (VEGGIE) program, set to hit the ISS later this year. This December, NASA plans to launch a set of Kevlar pillow-packs, filled with a material akin to kitty litter, functioning as planters for six romaine lettuce plants. The burgundy-hued lettuce (NASA favors the “Outredgeous” strain) will be grown under bright-pink LED lights, ready to harvest after just 28 days…
