claimFuture planetary protection policies face significant challenges from complex missions, including the Mars sample return campaign, exploration of the icy moons of Jupiter and Saturn, and human landings on Mars, which are occurring under programmatic constraints such as cost caps that were not generally present during the Apollo era.
claimThe 'Ocean Worlds' of the outer solar system, which include Jupiter’s Europa, Ganymede, and Callisto, and Saturn’s Enceladus and Titan, contain abundant liquid water beneath surface ice shells.
claimJupiter’s moons Ganymede and Callisto contain liquid water oceans, but these are sandwiched between upper and lower layers of ice, making them less interesting from an astrobiological perspective than Europa and Enceladus because there is no contact between the liquid water and the satellites' silicate cores.

claimThe Galileo mission, launched in 1989, released a probe to Jupiter in 1995.
claimThe majority of extra-solar planets discovered so far have masses comparable to or greater than Jupiter and are located too close to their central star to be suited for life.
claimResearchers have paid particular attention to the Jupiter satellite Europa due to the discovery of water, and to the Saturn satellites Enceladus and Titan due to their interesting morphological characteristics.
