To project JUICE (JUpiter ICy moon Explorer) launched the European Space Agency (ESA). Its purpose will be satellites of the planet Jupiter. Neighborhoods Callisto, Europa and Ganymede will visit the machine automatically, once on-orbit satellites, the last of these, he landed on his landing craft, which is tasked to produce scientists from the Russian Academy of Sciences.
For scientists, these satellites are extremely interesting. Especially Ganymede and Europa, where there are oceans of salt water, as shown by previous studies. Serious astrobiologists do not exclude the possibility that some of them may be living organisms. According to some of them, Ganymede and Europa are more attractive in this respect than Mars.
Scientists are interested in the thickness of ice of Ganymede and depth of its ocean covers if the water reaches a depth of 900 km, the entire surface of the satellite, or there is dry land. It is considered that it is not there, but it may not be the case.
On the icy crusts and Europe, and Ganymede have a crack, from which sometimes acts as if the water. The shape of cracks is very bizarre, like pipelines. Nearby are some grooves and strange footprints resembling sleigh. Some craters lined up in straight lines.
JUICE project will have to figure out how to form gas giants and their moons, to help understand how they are suitable for life.
Home studies will have to wait a long time: the unit is scheduled for launch in 2020, the arrival of the Jupiter system - in 2030.
