Sojourner Mars Rover

The Mars Pathfinder mission was widely proclaimed as "flawless" in the early days after its July 4th, 1997 landing on the Martian surface. Successes included its unconventional "landing" -- bouncing onto the Martian surface surrounded by airbags, deploying the Sojourner Mars Rover, and gathering and transmitting voluminous data back to Earth, including the panoramic pictures that were such a hit on the Web.

This photograph of the NASA Mars Science Laboratory rover, Curiosity, was taken during mobility testing on June 3, 2011. The location is inside the Spacecraft Assembly Facility at NASA's Jet Propulsion Laboratory, Pasadena, California USA.

Curiosity is about twice as long and more than five times as heavy as any previous Mars rover.

Its 10 science instruments include two for ingesting and analyzing samples of powdered rock delivered by the rover's robotic arm.

During a prime mission lasting one Martian year -- nearly two Earth years.
Researchers will use the tools on the rover to study whether the landing region has had environmental conditions favorable for supporting microbial life and favorable for preserving clues about whether life existed.

Curiosity, was shipped to NASA's Kennedy Space Center in Florida on June 23, 2011.
Launch: Nov. 26, 2011
Mars Landing: Aug. 6, 2012 (EDT)
The rover landed at the foot of a layered mountain inside the planet's Gale Crater.

JPL, a division of the California Institute of Technology in Pasadena, manages the Mars Science Laboratory mission for the NASA Science Mission Directorate, Washington.
