As multi-million dollar spacecraft crawl across our solar system, they could bring smaller passengers with them -- these tiny vehicles are called CubeSats and they've so far done a great job colonizing low Earth orbit.
Europa is an ice-covered moon orbiting Jupiter that likely an ocean underneath. Perhaps that ocean contains life. Perhaps it doesn't. But we're not going to know for sure until we send a probe there to check things out.
Ground control teams overseeing Europe’s Philae comet lander begin the week with some good news: The intrepid robot is back talking to the orbiting Rosetta spacecraft.
Ready for your close-up? How spacecraft changed our image of moons, planets and other objects in our solar system.
With its vast solar arrays on display at a Lockheed Martin Space Systems clean room in Denver, Colo., NASA's next mission to Mars stands proud.
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.
