Aeroponics Systems and NASA The only challenge that bothers astronauts is the adequate food supply for them into the space. The precise way space programs provide food to astronauts is to abundance maximum food that is required for the continuance of the mission. However, this isn't applicable for long continued missions, such as space flights, which takes astronauts to another planet. Eating canned food doesn't accord astronauts acceptable diet in the long run. For these reasons, NASA has been looking forward in researching the effects of no-gravity on vegetables. http://bit.ly/eIUDno http://bit.ly/iiC7mG
