Lander (spacecraft) a landing which should have come on 25 December 2003 was not received. Indeed, no communication was ever established and "Beagle 2" was declared lost on 6 February 2004. The proposed 2009 British Beagle 3 lander mission to search for life, past or present was not adopted. The French/ESA NetLander mission for 2007 or 2009, with an orbiter and 4 landers, was cancelled because it was too expensive. Its successor, Mars MetNet, a multi-lander mission for 2011–2019 was not adopted by the ESA. The American Mars Exploration Rovers "Spirit" and "Opportunity" were launched in June and July 2003. They reached
Mars Climate Orbiter the planned orbital insertion maneuver on September 23, 1999 at 09:00:46 UTC. "Mars Climate Orbiter" went out of radio contact when the spacecraft passed behind Mars at 09:04:52 UTC, 49 seconds earlier than expected, and communication was never reestablished. Due to complications arising from human error, the spacecraft encountered Mars at a lower than anticipated altitude and it was either destroyed in the atmosphere or re-entered heliocentric space after leaving Mars' atmosphere. "Mars Reconnaissance Orbiter" has since completed most of the intended objectives for this mission. On November 10, 1999, the Mars Climate Orbiter Mishap Investigation Board released a Phase
