We Are Off To Jupiter's Moons

It was always considered that our best hopes of finding alien life lie with Venus and Mars until we discovered that Venus had a surface temperature of 475C and Mars lost its atmosphere and surface water billions of years ago so now we are looking at Jupiters Moons, specifically Ganymede, Europa and Callisto which all have an icy layer which they think covers vast oceans, a prerequisite for life to begin.
It was also discovered in 2005 that Saturn’s tiny moon, Enceladus, is spraying water and organic material into space from an underground ocean but as this was unfortunately discovered too late for these missions, it hasn’t made it onto the places to visit list.
The European Space Agency launch will take place today but such is the vastness of Space, it won't arrive at its destination until eight years later, July 2031, and will remain in permanent orbit around Ganymede by which time it will have been overtaken by another probe, NASA’s Europa Clipper, which is taking a
shorter route and will arrive in April 2030.
The US spacecraft will focus on Europa and will make close approaches of the moon for three years to try to spot areas that could support life such as signs of hydrothermal vents which prompted life to start on Earth and lead us on the path to launching probes to look for them on other Solar System bodies.
Despite the two missions being run by separate space agencies, NASA and ESA have said there will be close collaboration and will coordinate joint missions, hopefully including taking peek at Enceladus so with various Moon Missions being planned, Space could be about to be sexy again.
