NASA is wrapping up testing on a helicopter that they'll use on Mars next year.

Building a helicopter for Mars takes a lot of engineering because Mars has very little air. Considering air is how helicopters get some lift to fly, you can imagine the challenges the scientists faced. Watch the video above for more.

We wouldn't be able to live outside on Mars because it has 99% less air than Earth.

If we were to live there, we'd have to grow plants in greenhouses. This is because the environment on Mars is like a desert in that it gets much colder at night. It's unlike a desert because it's pretty chilly during the day. Check out the current temperature on Mars.

Both the ground and air on Mars do a poor job of retaining heat. So, a greenhouse would capture enough heat from the sun to grow plants.
