Water on Mars?
In April 2001, NASA launched a special spacecraft to Mars, called Mars Odyssey, which still continues to orbit and study Mars. Mars Odyssey's main job was to test what kinds of elements and minerals make up the surface of Mars. They found hydrogen, which can be bonded with oxygen to form water. They found out that, as expected, the low temperature have turned the water into ice, but water was truly discovered on Mars in 2002. The ice was mixed with the soil on Mars just below the surface.
Why should we worry about whether there is water or even ice on Mars? Water is running short on Earth, even though 70% of earth is water. Actually, only 2.5% of that 70% is fresh water, and only .77% of 2.5% is accessible to us. So we'll need more water source, whereever possible. If anything happens to earth, we may be able to live on Mars and we will need to either make or find materials there to help us survive.
