Mars Science Laboratory landing site location was an elliptical area . Gale Crater's diameter is . The landing location for the rover was less than from the center of the planned landing ellipse, after a journey. NASA named the rover landing site Bradbury Landing on sol , August 22, 2012. According to NASA, an estimated 20,000 to 40,000 heat-resistant bacterial spores were on "Curiosity" at launch, and as much as 1,000 times that number may not have been counted. Mars Science Laboratory Mars Science Laboratory (MSL) is a robotic space probe mission to Mars launched by NASA on November 26, 2011, which successfully
Mars landing after Pillinger's death. The lander appears to have successfully landed but not deployed all of its power and communications panels. Shortly after the launch of Mars Express, NASA sent a pair of twin rovers toward the planet as part of the Mars Exploration Rover mission. On 10 June 2003, NASA's MER-A "(Spirit)" Mars Exploration Rover was launched. It successfully landed in Gusev Crater (believed once to have been a crater lake) on 3 January 2004. It examined rock and soil for evidence of the area's history of water. On July 7, 2003, a second rover, MER-B "(Opportunity)" was launched. It
