 A

From the moon to Mars, scientists have been looking for water—the key to life—in the solar system for many years. Recently, they have turned to Jupiter！Jupiter is a gas giant(巨星). It doesn't have an Earth­like surface. We can see strips(条纹)around it. They are actually cold, windy clouds.

On 14 April, the European Space Agency's(ESA)JUICE spacecraft successfully lifted off from French Guiana in South America. JUICE, short for “Jupiter Icy Moons Explorer”， will collect data(数据)from Jupiter and its three moons, Europa, Ganymede and Callisto.

The three moons are believed to have big oceans of liquid water(液态水)under their icy shells(壳). According to ESA, the water on those moons could be six times as much as the amount in Earth's oceans. The mission “will change our understanding of the solar system”， wrote Scientific American.

In 1998, NASA's Galileo spacecraft found that Europa might be ejecting(喷射)water as far as 160 kilometres into space. That gave scientists the idea of studying the icy moons of Jupiter.

The oceans under these moons are likely to be tens of kilometres deep. But they are also trapped under tens of kilometres of ice, making it very difficult to study them. Although JUICE cannot land on the surface, it has lots of high­tech equipment to study the moon's environment, including spectral imaging(光谱成像)tools and radar(雷达). They could give more data on things like the thickness of the oceans, their salt content(含量), and their distance from the icy shells above, reported Phys.org.

“The main goal is to understand whether there are habitable(可居住的)environments among those icy moons and around a giant planet like Jupiter，” JUICE team member Olivier Witasse said during a press conference(发布会)on 6 April.
