Mars has large amounts of water ice, especially near its poles and under the surface. Scientists believe the cold temperatures allow ice to stay frozen for long periods. The Viking 2 lander helped researchers study the Martian surface and climate. In this image, the bright white areas are believed to be frost or ice mixed with rocky soil. Studying water ice on Mars is important because it may support future human exploration and help scientists understand whether life could once have existed there.
