Since Apollo 14 there have been dozens of similar – albeit more scientifically rigorous – experiments involving sending seeds and plants into space. Today, astronauts on the International Space Station (ISS) regularly eat salad grown on board. In 2016, 2kg (4.4lb) of rocket seeds went to the ISS with British astronaut Tim Peake. The RAS"s research into the seeds said "results showed that, while the rocket seeds grew more slowly and were more sensitive to ageing, they were still viable".
