Plants grown on the International Space Station have produced seeds.
Astronauts have grown the mustard weed Arabidopsis thaliana from seeds that were
planted on Earth. After growing for a month in space, the plants produced
similar numbers of seeds to plants grown simultaneously on the ground. On a
future mission, a team of scientists led by Weijia Zhou at the Wisconsin Center
for Space Automation and Robotics will compare plants grown on the space station
from the space seeds with plants grown from ordinary seeds to see if there are
any differences.
