航天飞机变“菜园”(一)




Astronauts[宇航员] on the first manned missions to Mars could tend “kitchen gardens” onboard spaceships, scientists claim.

Experts say the crops would not only give crews[全体机员] healthy food to eat during the long journey to the red planet, but would also improve the atmosphere onboard by producing oxygen and removing carbon dioxide.

In addition, the plants suggested as suitable by a NASA scientist would require minimal tending and not take up much room on spacecraft[宇宙飞船].
