David Southwood from the Cassini mission to Saturn, landed successfully on Saturn’s largest moon, Titan. Southwood later described the Huygens landing as "the highest point of all" from his ESA career. Southwood had also led the team which developed the magnetometer on the main Cassini spacecraft. During 2003 ESA launched a largely British lander, Beagle 2, which was carried to Mars by the larger Mars Express spacecraft. All contact with Beagle 2 was lost before it reached the surface of Mars, and the project was considered a failure. ESA was heavily criticised for its management of the mission. Southwood suffered public criticism
Lander (spacecraft) any other or separate mission. Also, another proposal calls for a large nuclear-powered "melt probe" (cryobot) that would melt through the ice until it reached an ocean below where it would deploy an autonomous underwater vehicle (hydrobot) that would gather information. The Deep Space 2 impactor probe was to be the first spacecraft to penetrate below the surface of another planet. However the mission failed with the loss of its mother ship, Mars Polar Lander after communication was lost after entry into Mars atmosphere on 3 December 1999. Comet Tempel 1 was visited by NASA's "Deep Impact" probe on 4
