The Planet Mars

This section of Explore Mars provides basic information about the planet Mars. As a target of scientific investigation, I find that Mars is by far the most interesting object in the solar system. This is because of the many unanswered questions about our neighbor. For instance, what is the history of water on Mars? How has the martian climate changed over time? What exactly happened to the martian atmosphere? Were past conditions on Mars conducive to the development of life? Mars is also interesting because of its potential to be a future home for humanity and because the possibility exists for Mars to be terraformed.

Our state of knowledge about Mars is limited largely to the data that has been returned by the various flyby and orbiter missions, like Mariner, Viking, Pathfinder, and Mars Global Surveyor. While remote sensing has greatly expanded our knowledge of Mars, there is much that will remain unknown to us until we begin to carry out long-term human exploration missions.
