People have looked to Mars with curiosity since the earliest humans began gazing at the night sky. Now, we can do a lot more than just gaze in awe at Mars from the ground. We look with high-powered, space-based telescopes, such as the Hubble Space Telescopeand soon with the Next Generation Space Telescope. We send satellites and rovers to observe up close and look for evidence of ancient liquid waterand past lifeon Mars. The data and imagery we get back gets clearer and clearer as our technology gets more and more sophisticated. Pretty soon, well even have Martian rocks and soil to analyze. And someday, we may even voyage to Mars in person!

Looking for Likely Sites
NASA Goddard Space Flight Center's interactive topographic map of Marss surface was assembled using data from the Mars Orbiter Laser Altimeter (MOLA) on board the Mars Global Surveyor satellite.
The bands of color represent different heights. You can see lots of interesting features, such as volcanoes and canyons, when you look at Mars this wayincluding the fact that the northern hemisphere is much flatter than the southern hemisphere. Why? Thats one of the things todays scientists and researchers are trying to find out!
