growing vegetables in the universe

Growing cabbage in the universe, growing mushrooms to make medicines, testing inflated housing are experiments that can help bring people to Mars by the US Aerospace Agency (NASA).

Astronauts on the International Space Station (ISS) yesterday for the first time tasted long-leaf red lettuce grown in a zero gravity environment.

The gravityless environment in space stations is considered unsuitable for all types of long-term cultivation and survival.
