  3. Why Study Mars? • Search for life • Mars has water, atmosphere, sunlight - could it have life? • Comparison to Earth • Mars may have undergone a large change in its climate • Could we learn something about climate change on Earth? • Curiosity and exploration • Mars has the same land area as the Earth • It is a complex place - not just a point of light in the night sky Image Credit: NASA/JPL

  4. How Do We Approach This Problem? • What do we think all life needs? • Water • Look for environments where water may have existed • Landforms • Minerals • How do we do this? • Orbiters • Rovers • Returned samples • Human exploration • New ways of looking Image Credit: NASA/JPL/ASU
