[[Galileo Project|Galileo]] reached Jupiter in 1995. It released a probe to dive into Jupiter's atmosphere; that probe transmitted for nearly an hour before the tremendous pressures crushed it. Galileo's orbiter remained in the system for nearly eight years, through two extensions of its mission, and conducted the most extensive surveys of the Galilean moons to day. Eventually, with the craft low on fuel, mission planners dived it into Jupiter to prevent its possibly crashing into [[Europa]], rupturing Europa's ice sheet, and contaminating the liquid ocean that astronomers now suspect lies a mere 10 km deep to the ice and could yet harbor [[extraterrestrial life]].<ref name=nasa3/>
