Launch controllers oversee the countdown in the Atlas V Spaceflight Operations Center (ASOC) before the launch of the Mars Science Laboratory on an Atlas V rocket. MSL lifted off at 10:02 a.m. EST Nov. 26, beginning a 9-month interplanetary cruise to Mars. MSL's components include a car-sized rover, Curiosity, which has 10 science instruments designed to search for signs of life, including methane, and help determine if the gas is from a biological or geological source.
