Landings on moons of other Solar System bodies

21st century progress in space exploration has broadened the phrase moon landing to include other moons in the Solar System. The Huygens probe of the Cassini–Huygens mission to Saturn performed a successful moon landing on Titan in 2005. Similarly, the Soviet probe Phobos 2 came within 190 km (120 mi) of performing a landing on Mars ' moon Phobos in 1989 before radio contact with that lander was suddenly lost. A similar Russian sample return mission called Fobos-Grunt ("grunt" means "soil" in Russian) launched in November 2011, but stalled in low Earth orbit. There is widespread interest in performing a future landing on Jupiter 's moon Europa to drill down and explore the possible liquid water ocean beneath its icy surface.
