After its first failed attempt on Thursday, NASA’s twin satellites were finally launched on Saturday morning, said the agency.

An out-of-use NASA science satellite will plunge back to Earth soon, sparking concerns that some debris might shower down on populated areas.

A defunct NASA satellite is expected to re-enter Earth's atmosphere by early October, sparking concerns that some debris might shower down on populated areas.

NASA finally launched its GRAIL mission, Gravity Recovery and Interior Laboratory, from Cape Canaveral Air Force Station in Florida on Saturday, its first mission to map the Moon's inner core.

While those nearby in New York City on the fateful day in Sept. 2001 saw devastation miles away from the World Trade Center, NASA's Frank Culbertson saw 9/11 firsthand from much further away: from space.

The rovers Spirit and Opportunity contain shields emblazoned with American flags that NASA said was constructed as a memorial to the Sept. 11 terrorist attacks.

NASA is on its way back to the moon, embarking upon a new study that could help launch future manned missions one day.NASA's Grail mission launched this morning, as the Delta II rocket carrying the Gravity and Recovery and Interior Laboratory lifted off from Cape Canaveral, Fla. Saturday at 6:08 a.m. EDT amid clear skies. It is the 110th mission to the moon in history, with previous missions launched by the United States, Soviet Union, Japan, China and India.

Spectators at the Cocoa Beach became witness to the third attempt by NASA to launch the dual-spacecraft mission finally as it lifted off from Cape Canaveral.

NASA astronaut Frank Culbertson was the only American not on Earth when the 9/11 terrorist attacks happened 10 years ago, He was on board the International Space Station and filmed the shocking incident.

NASA had scratched the planned launches on Thursday and Friday, initially because of foul weather and then because of a data glitch.

After a two-day delay NASA finally launched a pair of satellites from Cape Canaveral Air Force Station in Florida on Saturday on its first mission to study the moon in unprecedented detail.

The 6.5 ton falling NASA satellite will hit earth’s atmosphere by early October filling a 500-mile-wide range of land in Britain, Europe, northern Canada and southern South America and three oceans with its remains.

An out of use NASA science satellite will be plunging back to Earth soon, sparking concerns that some debris might shower down on populated areas.

NASA astronaut Frank Culbertson will never forget where he was on 9/11: On board the International Space Station flying over the New York City area when he spotted the smoke.

At this point, astronomers don't know anything about the invisible world Kepler-19c, other than that it exists.

A NASA satellite is expected to make a crash landing on Earth in late September or early October. No one knows where it will land, not even NASA. It could even land on you -- but luckily, you have a better chance of winning the lottery than of having a piece of the satellite fall on your head.

A defunct 7-ton research satellite is falling in the direction of earth and has the potential of raining debris on densely populated areas including Britain, NASA reports.

NASA has delayed the GRAIL launch one more day in order to review propulsion system data from Thursday's detanking operation.

A defunct 7-ton research satellite is falling earth bound,due to re-enter the atmosphere with a potential to rain debris on densely populated areas including Britain, NASA reports.

NASA has released footage of 9/11 shot by astronaut Frank Culbertson, who was on the International Space Station on September 11.

Astronomers have outdone themselves by doing the (seemingly) unimaginable: Discovering an invisible exoplanet.
