Various reports say that the U.S. space agency, NASA, is thinking of ways to grow food on Mars. This is, in fact, a part of the much larger project to land human beings on the red planet by 2030.
The soil samples collected by NASA's Mars rover show that being an arid desert, the ground will have to be tilled and cultivated to stand any chance of astronauts being able to grow even the simplest of food items there. The ability to grow various crops for survival is the basic requirement if the red planet is to support human settlement some day.
