Mars Reconnaissance Orbiter:
Mars Reconnaissance Orbiter will track changes in the water and dust in Mars' atmosphere, look for more evidence of ancient seas and hot springs and peer into past Martian climate changes by studying surfance minerals and layering. The orbiter will carry a powerful camera capable of taking sharp images of surface features the size of a beach ball.
At the conclusion of its 2-year science mission, Mars Reconnaissance Orbiter will serve as a data relay station for future Mars missions.
