• Question: If the seeds experiment onboard the ISS proves unsuccesful, would genetically modifying the seeds be a viable option to try and get seeds to grow in zero-gravity?

      Hi 11P SHS,

      I don’t think genetic modification is necessary to allow seeds to germinate and grow into plants in a zero-gravity environment: many experiments with seeds and plants have already been done in zero-gravity and it is now thought that plant growth in the absence of gravity is not a problem. See for example the salad that astronauts grew a few months ago on the ISS: http://www.space.com/30209-astronauts-eat-space-lettuce.html
