NASA is set to launch a jumbo spacecraft, Europa Clipper, to see if an icy moon of Jupiter has the characteristics of a ...

It won't land, but the robotic spacecraft will fly as close as 16 miles to the moon's frozen surface to probe oceans of ...

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 ...

The Galileo probe flew past it in the 1990s, confirming scientists' initial hopes that the moon was more than the quiet rocky ball orbiting Earth. The excitement led scientists to formally ask ...

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

The ambitious mission won't actually look for life, but it should find out if the presumed ocean provides a habitable environment.

Abstract: As the Galileo probe Relay Radio Link (RRL) signal propagates outward through the Jovian atmosphere, the atmosphere will manifest itself in two ways. First, the geometric path length of the ...

PARIS, Oct 7 (Reuters) - Europe's Hera asteroid probe blasted off from Florida on a SpaceX rocket on Monday, beginning a two-year voyage to revisit an asteroid bashed off course by NASA's DART ...

with the flyby distances gradually dropping from 18 miles (30 kilometers) all the way down to a half-mile (1 kilometer). The spacecraft will survey the moonlet for at least six months to ascertain ...
