These objects provide functionality for manipulating data from the Mars Reconnaissance Orbiter mission.Mars Reconnaissance Orbiter, scheduled for launch in 2005, is on a search for evidence that water persisted on the surface of Mars for a long period of time. While other Mars missions have shown that water flowed across the surface in Mars' history, it remains a mystery whether water was ever around long enough to provide a habitat for life.
