Astronaut Scott Kelly initiated VEG-01 B, the second crop of lettuce, on July, 8, 2015, and both Kelly and Astronaut Kjell Lindgren cared for the plants. The crop grew for 33 days. VEG-01 B included one set of six plant pillows planted with red romaine lettuce seeds.
On Aug. 10, 2015, the crew harvested and consumed leaves from each plant. This was the first crop grown and consumed in space. They harvested the rest of the plant tissue and froze it in the station’s Minus Eighty-Degree Laboratory Freezer for ISS (MELFI) for return to Earth for further study including microbial analysis, antioxidant capacity, mineral analysis and anthocyanin concentration.
