Mars Reconnaissance Orbiter

Overview

NASA's Mars Reconnaissance Orbiter is a spacecraft that searches for evidence that water persisted on the surface of Mars for a long period of time. Launched in 2005 and still operating, the orbiter uses advanced imaging and scientific instruments to study the distribution and history of water on Mars, analyze minerals, look for subsurface water, and monitor the Martian atmosphere and weather. It serves as a crucial communications relay for other Mars spacecraft.
