NASA astronauts on board the International Space Station reaped the first harvest of red romaine lettuce leaves grown on the orbiting space lab last month. These vegetables were grown using the “Veggie” plant growth system on the International Space Station (ISS), and were harvested as part of a technique.

Highlights

  • Space Station reaped the first harvest of red romaine lettuce leaves grown on space lab.
  • Cut-and-come-again is a repetitive harvest technique in which a selection of leaves can be harvested for a bit of fresh lettuce and possibly science sample.
  • Once the plants are approximately four weeks old, a selection of leaves can be harvested for a bit of fresh lettuce and possibly science samples
  • Remaining leaves and the core of the plant are left intact and will continue to grow and produce more leaves for subsequent harvests approximately every 10 days.
  • Goal of this technique is to improve the yield of crops being grown in the micro-gravity environment of space.

About International Space Station                   

  • International Space Station (ISS) is a space station, or a habitable artificial satellite, in low Earth orbit.
  • Its first component launched into orbit in 1998, and the ISS is now the largest artificial body in orbit and can often be seen with the naked eye from Earth.
  • ISS components have been launched by Russian Proton and Soyuz rockets, and American Space Shuttles.
  • Microgravity: The Earth’s gravity is only slightly weaker at the altitude of the ISS than at the surface, but objects in orbit are in a continuous state of freefall, resulting in an apparent state of weightlessness.
