SPACE – The search for extraterrestrial life takes a new step. NASA has indeed received the latest approvals to ship its Europa Clipper spacecraft orbiting around Jupiter, it reports The Guardian. She would have to leave by 2025 to investigate her frozen moon, Europe.

Europe is only one of Jupiter's 79 moons. But according to scientists, it is one of the stars of the solar system that is most conducive to the discovery of life. This is what the mission will try to verify, as you can see in our video at the beginning of the article.

Europa Clipper circles around Jupiter and makes 45 flights across Europe, from 25 to 2700 kilometers. It cannot circle directly around the moon Europe, because the radiation from the radiation belt of Jupiter would be fatal in the long term.

The probe has a radar that penetrates the ice, to determine the thickness of the outer layer of the moon Europe, and a thermal instrument that will search for recent geysers on the surface. Studying the composition of these possible water jets would provide a lot of information about the chemical composition of Europe without drilling ice caps.

Because under this ice Europe can hide a gigantic ocean of liquid water, in contact with the rock, like lakes below the surface of Antarctica. And this ocean can perhaps accommodate an extraterrestrial life.

This requires three elements: liquid water, an energy source through the tidal heat and carbon-containing organic matter. The radar must confirm whether these three elements are present in the basement of Europe.

Finally, the mission also wants to look for microparticles and water in the European atmosphere. The cameras' & spectrometers of the probe will meanwhile study the composition of the lunar surface of Europe.
