The Planet Mars
Several underground streams.
Early in time Mars was much like earth. It had lakes and streams above
the surface and we think quite possibly oceans. But now mars just has frozen
ice caps and underground frozen rivers. Mars?s surface is very old and
has many craters. However other than earth mars has the most interesting
terrain out of all the planets in the solar system.
Canyons on Mars
Mars has a very thin atmosphere and the very little carbon dioxide
the atmosphere is made of is what makes it so thin. The first spacecraft
to land on mars was mariner 4. There was also others like mars 2 and Viking.
Vikings mission was to take tests to determine if there was life on mars.
But they could not find such proof. The latest craft to land on mars was
the mars pathfinder witch successfully landed July 4 1997.
