NASA's next mission to Mars will examine it in unprecedented detail from low orbit, and it will provide more data about this intriguing planet than all previous missions combined. The spacecraft will examine Martian features ranging from the top of the atmosphere to underground layering. Researchers will use it to study the history and distribution of Martian water. It will also support future Mars missions by characterizing landing sites and providing a high-data-rate communications relay.
Launch opportunities begin Aug. 10 for the much heralded Mars Reconnaissance Orbiter. The orbiter and its launch vehicle are nearing final stages of preparation at NASA's Kennedy Space Center, Fla. "Mars Reconnaissance Orbiter is the next step in our ambitious exploration of Mars," said NASA's director of the Mars Exploration Program, Douglas McCuistion.
"We expect to use this spacecraft's eyes in the sky in coming years as our primary tools to identify and evaluate the best places for future missions to land."

The large silver circular feature above the spacecraft bus is the high-gain antenna,
the spacecraft's main means of communicating with both Earth and other spacecraft.
The long, thin pole behind the bus is the SHARAD antenna.
The Electra telecommunications package is the gold-colored instrument. It will
act as a communications relay and navigation aid for future Mars spacecraft.
The spacecraft carries six instruments for probing the atmosphere, surface and subsurface to examine the planet to help determine how it has changed over time. One of the science payload's three cameras will be the largest-diameter telescopic camera ever sent to another planet. It will reveal rocks and layers as small as the width of an office desk. Another camera will expand the present area of high-resolution coverage by a factor of 10. A third will provide global maps of Martian weather.

The other three instruments are a spectrometer for identifying water-related minerals in patches as small as a baseball infield; a ground-penetrating radar, supplied by the Italian Space Agency, to peer beneath the surface for layers or rock, ice and, if present, water; and a radiometer to monitor atmospheric dust, water vapor and temperature.
