Jo Johnson finds out that it is Rocket Science

Visitors to the RHS Chelsea Flower Show found out what are the top 10 food plants that ESA scientist Christophe Lasseur thinks should be taken on long-duration space missions. Newly appointed UK Minister for Universities and Science, Jo Johnson casts his vote. Visitors can consider the importance of plants in our daily lives by focusing on plants as producers of oxygen and food for space missions beyond Low Earth Orbit (which is where the International Space Station is right now). Votes can be cast for the public’s favourite plant by placing tokens in the collecting boxes beneath each of top 10 food plants on display:

Potatoes
Soft White Wheat
Soya
Spinach
Lettuce
Tomatoes
Beetroot
Onions
Rice
Spirulina (not a true plant but a blue green Algae with high rate of photosynthesis)
