Curiosity at Work on Mars (Artist's Concept) This artist's concept depicts the rover Curiosity, of NASA's Mars Science Laboratory mission, as it uses its Chemistry and Camera (ChemCam) instrument to investigate the composition of a rock surface.

NASA’s newest astrobiology mission to Mars called the Mars Science Laboratory (MSL) is set to launch from Cape Canaveral Air Force Station in Florida on Saturday, November 26th. The one hour and 43 minute launch window opens at 10:02 a.m. EST.

It’s been more than eight years since NASA has sent a rover to explore Mars. And although both of the rovers from 2003’s Mars Exploration Rovers (MER) Mission, called Spirit and Opportunity, transmitted valuable data long after they were expected to expire, the newest rover, Curiosity, will be able to collect data far beyond the scope of any past mission.

Curiosity is a car-sized rover which will search areas of Mars for past or present conditions favorable for life, and conditions capable of preserving a record of life.

Curiosity consists of 10 instrument-based science experiments including a geology lab, a rock-vaporizing laser, a gas chromatograph mass spectrometer and several special cameras. Curiosity will use the laser to look inside rocks and release their gasses so its spectrometer can analyze and send the data back to Earth.

After launch, the spacecraft will travel approximately 354 million miles, landing on Mars in early August 2012.

Once Curiosity starts working on Mars, an international team of scientists and engineers will make daily decisions about the rover’s activities for the following day. NASA’s Jet Propulsion Laboratory in Pasadena, Calif., builder of the MSL, has engineered Curiosity to roll over obstacles up to 25 inches high and to travel up to about 660 feet per day on Martian terrain. Curiosity’s primary mission will last one Mars year (98 weeks).

NASA Ames Research Center in Mountain View, California contributed to the design and engineering of several elements of the new rover. Ames scientist David Blake is the principal investigator for one of the main instruments called CheMin, an X-ray diffraction and fluorescence instrument designed to identify and quantify the minerals in rocks and soils, and to measure bulk composition. CheMin data will be useful in the search for potential mineral biosignatures, energy sources for life or indicators of past habitable environments.

On Saturday, Nov. 26, NASA TV coverage of the launch will begin at 4:30 a.m. PST. Recorded launch status reports will be available starting Nov. 21 on the Kennedy Space Center media phone line, 1- 321-867-2525. Extensive prelaunch and launch day coverage of the liftoff of the Mars Science Laboratory spacecraft aboard an Atlas V rocket will be available on NASA’s home page.
