The space agency has chosen the eight proposals to provide instrumentation and associated science investigations for the mission, which is intended to explore a local region as a potential habitat for past or present life.

Cornell professor of astronomy Steve Squyres is on the teams for two of the experiments, the Sample Analysis at Mars (SAM) and the Alpha-Particle-X-Ray-Spectrometer (APXS). Squyres currently is principal investigator for the Mars Exploration Rover (MER) mission, which has two rovers conducting scientific experiments on opposite sides of the planet.

Jim Bell, associate professor of astronomy at Cornell, and senior researchers Rob Sullivan and Peter Thomas are on teams for three imaging experiments from Malin Space Science Systems, San Diego, Calif.

Bell currently is leading the panoramic camera, or Pancam, team for the MER mission. Sullivan also is a member of that team, which has its calibration and processing lab for the mission's panoramic images on the Ithaca campus.

Thomas is a member of both the Cassini Saturn obiter team and the science team for the forthcoming Deep Impact mission that next year will collide a large projectile with the comet Tempel 1.

The SAM is an integrated suite consisting of a gas chromatograph mass spectrometer and a tunable laser spectrometer. The APXS would determine elemental abundance of rocks and soil and will be provided by the Canadian Space Agency.

One of the Malin proposals is a mast-mounted camera that would perform multi-spectral, stereo imaging at lengths ranging from kilometers to centimeters and would be able to acquire compressed high-definition video at 10 frames per second without the use of the rover computer. One of the camera's co-investigators is movie-maker James Cameron, director of "Titanic.

"The other Malin instruments are a "hand lens" imager for imaging rocks, soil, frost and ice at resolutions 2.4 times better--and with a wider field of view--than the microscopic imager carried by the current Mars rovers; and a Mars descent imager that would produce high-resolution, color-video imagery of the MSL descent and landing phase, providing geological information as well as pinpointing the landing site.

The MSL mission is scheduled to arrive on Mars in 2010. The MSL operates under its own power and would be expected to remain active for two years (one Martian year).

The mobile laboratory also would carry a pulsed neutron source and detector for measuring hydrogen (including water), a meteorological package and an ultraviolet sensor.

Malin Space Systems' founder and president is Michael Malin, who has a long history of collaboration with Cornell's Department of Astronomy. The company built and operates the Mars orbital camera aboard the Global Surveyor spacecraft, which was launched in 1996 and continues to orbit the planet.

The company has built two cameras for NASA's 2005 Mars Reconnaissance Orbiter mission and the descent imager for the 2007 Mars Scout Phoenix mission.
