Mars Science Lab
The US space agency successfully landed its one tonne robot rover, Curiosity, on Mars this week. It will now embark on a mission of at least two years to look for evidence that Mars may once have supported life. The signal confirming the rover was on the ground safely was relayed to Earth via NASA's Odyssey satellite, which is in orbit around the Red Planet. The success was greeted with a roar of approval here at mission control at the Jet Propulsion Laboratory (JPL) in Pasadena, California.
