According to new research, after cultivating lettuce in space three years ago, crew members aboard the International Space Station could be growing beans in 2021.
-
The beans could be planted in high-tech planters developed at the Norwegian University of Science and Technology (NTNU).

-
The planters can regulate all the water, nutrients, gas and air the plants need.
-
NTNU was collaborating with Italian and French researchers to cultivate plant-based food for long space journeys.
-
The food grown in space could be crucial to sustain the crew in future deep space missions.

Effect of gravity:
-
The next step is to grow beans in space to observe the effect of no gravity on plants’ ability to transport water and absorb nutrients.
-
Simulating the absence of gravity cannot be done on Earth.
-
The beans would be placed in a centrifuge to sprout and grow in the space station.
-
The centrifuge would be rotated to create different amounts of gravity.
