Europe launched a new bid Friday to communicate with its comet lander Philae, hurtling towards the sun some 360 million kilometers (224 million miles) from Earth.
A robotic spacecraft that circled Mercury detected magnetized rocks, evidence that planet’s still-roiling, liquid metal core likely spawned a global magnetic field as far back as about 3.8 billion years ago.
As it zoomed danger-close to small planet's surface at a mind-boggling 8,700 miles per hour, MESSENGER managed to beam one last look at the Mercurian landscape back to Earth.
NASA has released a map of the region where the spacecraft is expected to crash.
Transport yourself to Mars and stare in wonder at these stunning views of Red Planet sunsets through our robotic explorers' eyes.
As far as rocks on any planet go, this formation looks fascinating -- but these rocks are on Mars and they hold clues to TWO periods of water on the red planet.
Although engineers identified the problem and applied a software fix for Opportunity's amnesia events, the aging NASA mars rover has again been afflicted with further memory issues.
Good news from Mars: Rover Opportunity has been uploaded with new software and the memory issues that plagued the mission for several months have been fixed. For now.
