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
The Mars Project are other shortcomings in "The Mars Project" that von Braun could not have anticipated in 1948. He had not planned on any unmanned exploratory missions to Mars taking place before the first manned expedition, and he had not foreseen the technological advances that would take place, or the development of robot spacecraft. It was not until 1965 that the unmanned Mariner 4 spacecraft found that the density of the Martian atmosphere was only one tenth of what had been estimated, making it clear that the huge winged gliders planned by von Braun would not have had enough lift to be
