National Aeronautics and Space Administrion

Since its inception in 1958, NASA has accomplished many great scientific and technological feats in air and space. NASA technology also has been adapted for many nonaerospace uses by the private sector. NASA remains a leading force in scientific research and in stimulating public interest in aerospace exploration, as well as science and technology in general. Perhaps more importantly, our exploration of space has taught us to view Earth, ourselves, and the universe in a new way. While the tremendous technical and scientific accomplishments of NASA demonstrate vividly that humans can achieve previously inconceivable feats, we also are humbled by the realization that Earth is just a tiny "blue marble" in the cosmos. Check out our "Thinking About NASA History" folder online as an introduction to how history can help you.

Mars


Mars is a much smaller, red version of the Earth. The most probes have visited it, out of all the planets in our Solor System and they still do. Mars has a diameter of 4, 222 miles.
Mars has a rocky crust as well as unbreathable methane atmosphere, which is Methane gas. The crust is red from the rust it has.

It's day is 40 minutes longer than a day on Earth. It has a year which is twice as long. Mars has a 25 degree tilt. This planet haso water reserves left from a few of the astroids. The largest mountain is called Olympia Mons. It has the biggest volcano range.

An area near the equator has a frozen sea. Water is still present on Mars. The poles hold enough water to cover the planet with 36 feet. The moons appear to be trapped by the magnetic core. One moon, Phobos, is 16.8 feet long, while the other, Deimos is 9.3 miles long.
