Making the Red Planet Green

Inside a chamber about the size of a small fridge in Greenville, Indiana, scientists are taking the first steps toward creating human settlements on Mars.

The chamber, called the Martian Environment Simulator, was put together by scientific engineering company SHOT and NASA's Institute for Advanced Concepts. Scientists are using it to determine how to grow plants in greenhouses on other planets, and hope it will eventually aid people living and working on Mars, as well as provide insight to the evolution of planetary life.
