"This is the real deal. Voyager 1 has finally reached interstellar space; the first time a spacecraft has been in the space between the stars," says one project scientist. Launched in 1977, the probe has been surveying the solar system.

The venerable probe has finally departed for interstellar space, but there's a reason the news might give you a feeling of deja vu.

The LADEE spacecraft, which began its trip to the moon last night in a launch on Virginia's coast, ran into some mechanical problems, NASA says. But officials say the robotic probe remains on track to reach the moon next month.

A rocket launched from NASA's launch pad on the Virginia coast shortly before midnight Friday was potentially visible to a large swath of the eastern U.S. The spacecraft is now on its way to the moon.

The U.S. Air Force has pulled the plug on a radar system that tracks thousands of objects orbiting Earth, from satellites and debris to meteors. The military says the shutdown can save $14 million annually. A replacement plan is in the works.

Mars had more of the key minerals needed to get life going, a researcher says. He theorizes that some of the rocks that have traveled from the Red Planet to Earth had those elements and gave life here a kick start.

One of seven large mirrors for the 72-foot telescope will be spun cast at the University of Arizona on Saturday.

NASA says the small object that was caught on video by a spacecraft called the Solar and Heliospheric Observatory was most likely a member of a sun-grazing group of comets known as the Kreutz family.

For the past decade or so, scientists have been waiting for the Voyager 1 spacecraft to cross into deep space. New research suggests it already has — over a year ago.

The giant space rock that slammed into Chelyabinsk in February sent material into the stratosphere that circled the globe in just four days and lingered for months.
