After an eight month journey, NASA’s multi-billion dollar rover Curiosity made a successful landing on Mars early this morning. Mission controllers cheered after the six-wheeled, one-ton machine made a perilous seven-minute landing involving a parachute, rocket pack and sky crane.

Since 1995, scientists have confirmed the existence of more than 700 so-called exoplanets, but most of them have been massive. Now, though, they’ve found a new one — and it’s even smaller than Earth.

Houston's "consolation prize" in NASA's space shuttle giveaway has arrived.  The 65 ton full-scale model named Explorer has been towed from the Kennedy Space Center in Florida to Space Center Houston, the tourist attraction next door to the Johnson Space Center.

It's true.  A NASA sponsored study in Houston shows brain scans of astronauts who were in space for more than a month revealed potentially serious abnormalities that could force NASA to delay or even cancel plans for longer deep space missions.

When the mock Space Shuttle Explorer is moved to Clear Lake from Kennedy Space Center later this year, it will get a new name – and that name will be chosen by Texas children in a statewide contest.

The largest solar storm in five years has engulfed Earth, but scientists say the planet has lucked out -- so far.  It's the result of one of the largest and most dramatic solar explosions ever seen.

Forget about that Mayan Doomsday prophecy -- the one that says the world will come an end this December.  Not very many credible people take that one seriously. But a lot of people with credible credentials say an asteroid will come close to Earth next February, and it should be taken very seriously because it could hit the Earth.

A camera aboard one of NASA's twin Gravity Recovery And Interior Laboratory (GRAIL) lunar spacecraft has returned its first unique and historic view of the far side of the moon.
