The International Space Station is now testing space grown lettuce for human consumption.

Universe Today reports that NASA’s Veggie experiment was initiated on May 8. The experiment began after a successful (if slightly delayed) launch to the Space Station on April 18 aboard a SpaceX Dragon capsule. In development for several years, the LED-powered plant growth experiment is finally getting the chance to put down its roots.

After receiving the experiment on Sunday, April 20, Expedition 39 astronauts Rick Mastracchio and Steve Swanson installed the Veg-01 unit inside ESA’s Columbus module on May 7. The next day Veg-01 was turned on, with a root mat and six small pillows containing “Outredgeous” romaine lettuce seeds within a special fertilized clay inserted inside its collapsible Teflon bellows.

The lettuce plants are scheduled to grow for 28 days, during which time they will be periodically photographed, watered, and tested for any microbial growth. The pillows will be thinned down to one plant each, and after the experiment is over the remaining lettuce leaves will be harvested and frozen to be returned to Earth aboard another Dragon capsule later this year. There they’ll be tested and compared with the results of an identical Veggie experiment that’s being conducted at the same time at Kennedy Space Center.
