What does it take to demonstrate a radar system is ready to look through the frozen crust of a distant moon when the ultimate ...

A radar on a spacecraft, intended to investigate the mystery of an extraterrestrial ocean, was never completely tested in Earthly chambers because there wasn’t a chamber large enough on our planet.

As it soared past Mars in March, NASA's Europa Clipper conducted a critical radar test that had been impossible to accomplish ...

The Mars flyby in March was primarily to use the planet's gravitational pull to tweak the Europa Clipper's trajectory.

American space agency NASA says it used the gravity assist maneuver the Europa Clipper conducted back in March to test the ...

NASA’s Europa Clipper spacecraft just aced a key radar test while flying past Mars, proving its ability to detect structures ...

Europa Clipper's radar instrument received echoes of its very-high-frequency radar signals that bounced off Mars and were ...

NASA's Europa Clipper nailed a major radar test during a Mars flyby, proving it’s ready to peer into Europa’s mysterious icy shell and search for underground oceans.

From a half-million miles away, NASA's Europa Clipper spacecraft captured Mars with its two moons, Phobos and Deimos, in ...

NASA scientists recently used Europa Clipper’s instruments to take readings of Mars, as the spacecraft was passing within just 550 miles of the red planet’s surface on March 1.

Once it launches, ahead of the Clipper is a 1.8 billion-mile journey to Europa on a trajectory taking it past Mars and then Earth, using the planets’ gravity as a slingshot to add speed for the ...
