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.

Life on Mars little is known about the growth of microorganisms at pressures close to those on the surface of Mars. Some teams determined that some bacteria may be capable of cellular replication down to 25 mbar, but that is still above the atmospheric pressures found on Mars (range 1–14 mbar). In another study, twenty-six strains of bacteria were chosen based on their recovery from spacecraft assembly facilities, and only "Serratia liquefaciens" strain ATCC 27592 exhibited growth at 7 mbar, 0 °C, and CO-enriched anoxic atmospheres. Liquid water is a necessary but not sufficient condition for life as we know it, as habitability
