NASA's Mars Reconnaissance Orbiter, launched in 2005, is searching 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.

[edit] Science Goals

Mars Reconnaissance Orbiter seeks to obtain science data that will provide researchers with information for locating safe landing sites for future missions and tell researchers about the history of water on Mars. The spacecraft instruments will zoom in for extreme close-up images of the Martian surface in order to analyze minerals, look for subsurface water, trace how much dust and water are distributed in the atmosphere, and monitor daily global weather.

These studies will help determine if there are deposits of minerals that form in water over long periods of time, detect any shorelines of ancient seas and lakes, and analyze deposits placed in layers over time by flowing water. It will also be able to tell if the underground ice discovered by the Mars Odyssey orbiter is the top layer of a deep ice deposit, or if it is a shallow layer in equilibrium with the current atmosphere and its seasonal cycle of water vapor.

The orbiter's primary mission ends about three Earth years after launch, in November 2008. For details on all mission stages, see the Mission Timeline (NASA).

[edit] Science Instruments

During its two-year primary science mission, the Mars Reconnaissance Orbiter will conduct eight different science investigations at Mars. The investigations are functionally divided into three purposes: global mapping, regional surveying, and high-resolution targeting of specific spots on the surface.

  • HiRISE (High Resolution Imaging Science Experiment) This high-resolution, visible-range camera can reveal small objects in the debris blankets of mysterious gullies and details of geologic structure of canyons, craters, and layered deposits.
  • CTX (Context Camera) This camera will provide wide area views to help provide a context for high-resolution analysis of key spots on Mars provided by HiRISE and CRISM.
  • MARCI (Mars Color Imager) This weather camera will monitor clouds and dust storms.
  • CRISM (Compact Reconnaissance Imaging Spectrometer for Mars) This spectrometer covers the range of visible and near-infrared light, useful for identifying minerals, especially those likely formed in the presence of water.
  • MCS (Mars Climate Sounder) This atmospheric profiler will detect vertical variations of temperature, dust, and water vapor concentrations in the Martian atmosphere.
  • SHARAD (Shallow Radar) This sounding radar will probe beneath the Martian surface to see if water ice is present at depths greater than one meter.
