Discovery of Mars
Mars is a bright, red object in the sky. It is very easy to see, which means that even people that lived long ago knew it was there. So, we don't know who discovered it. We do know it was named after the Roman god of war .
A scientist named Giovanni Schiaparelli saw many long lines on Mars. He thought they were water canals made by creatures! Later we sent spacecraft to Mars to study it.
Mariner 9 was the first to orbit Mars. It took lots of pictures of volcanoes and craters. It even found Olympus Mons , a giant volcano! The Viking I and II spacecrafts landed on Mars and studied rocks and the soil. Even today the Mars Global Surveyor is mapping the planet!

...more The atmosphere of Mars is much thinner than that of Earth, with a surface pressure averaging 1/100th that at the surface of the Earth. Surface temperatures range from -113oC at the winter pole to 0oC
...more The uniquely red global surface of Mars is marked by many interesting features - some like those on the Earth and others strangely different. The reddish color is caused by rust (iron oxide) in the soil.
