For the first time, we are sending a spacecraft to explore an alien ocean world—a moon that might host life today ...

NASA and SpaceX have launched NASA’s Europa Clipper mission to Jupiter’s icy moon Europa atop a SpaceX Falcon Heavy rocket.

Clipper isn’t the first mission to explore the icy moon. The Galileo probe flew past it in the 1990s, confirming scientists’ hopes that the moon was more than the quiet rocky ball orbiting Earth.

These plumes have been tentatively detected by the Hubble Space Telescope and in data from the Galileo spacecraft, which orbited Jupiter from December 1995 to September 2003. With a little luck ...

Planetary scientists have grown increasingly certain that Europa hosts a subsurface ocean ever since NASA’s Galileo spacecraft visited Jupiter in the 1990s (SN: 2/18/02). “During the Galileo ...

NASA’s Galileo spacecraft had repeated flybys of the moon during the 1990s, passing as close as 124 miles. Still in action around Jupiter, NASA’s Juno spacecraft has added to Europa’s photo ...

The Voyagers provided the first detailed photos of Europa but from quite a distance. NASA's Galileo spacecraft had repeated flybys of the moon during the 1990s, passing as close as 124 miles (200 ...

Nasa’s mission to a Galilean moon of Jupiter that’s encrusted in a thick shell of ice will let us know if its bulky ocean has ...
