ISS Astronauts Ate Lettuce That Was Grown In Space

The lettuce grew on the ISS for 33 days in microgravity, sustained by "plant pillows" that kept soil from escaping. Before eating the leaves, the astronauts had to wipe them off with citric acid wipes. NASA hopes that cultivating food in space will lead to new developments in farming on Earth, as well as ideas for agriculture on other planets. Fortunately, the presence of the plants is also thought to boost the moods of the astronauts.
