Saturday saw a first for NASA and the International Space Station, as two astronauts conducted an impromptu spacewalk to try to locate the source of a problem on the craft's exterior.

The space agency hadn't yet ordered such a spur-of-the-moment maneuver in regard to the ISS, according to the Associated Press, but when crewmembers on the craft spotted ammonia flakes floating through space beyond a window Thursday, the spacewalk was hastily planned.

After Mission Control and the ISS crewmembers prepped intensely -- for less than 48 hours -- astronauts Thomas Marshburn and Christopher Cassidy exited a hatch and … Read more

The International Space Station is leaking ammonia coolant used to prevent the station's power systems from overheating, but it doesn't pose a danger to the crew, NASA announced Thursday.

Crew aboard the space station alerted Mission Control to the appearance of small white flakes floating away from the station's P6 truss solar array this morning, NASA said in a statement. The ammonia loop affected is the same loop at which spacewalking astronauts attempted to troubleshoot a leak last November, NASA reported.

"There's a very steady stream of flakes or bits coming out as the truss … Read more

It was once described as a "glorified crane," but was so much more than that.

Tireless cargo handler, astronaut platform, and critical inspection tool, the Canadarm was an essential component of NASA's space shuttle fleet from 1981 to 2011.

This past week, it became a permanent exhibit at the Canadian Aviation and Space Museum in Ottawa.

"This exhibit commemorates an important part of our history in space," Canadian Heritage Minister James Moore said at a ceremony to unveil the exhibit. "The Canadarm is a symbol of our country's ingenuity and expertise in space robotics. It has positioned Canada as a leader in space." … Read more

NASA released the most detailed images ever seen of a gigantic hurricane that scientists believe has existed at Saturn's north pole for years.

NASA's Cassini spacecraft snapped the spectacular pictures this past November from a vantage point approximately 261,000 miles from Saturn -- a distance so extreme that the above picture has an image scale of about 1 mile per pixel.… Read more

If you've got $200,000 to spend on a ticket to suborbital space, your spaceship is nearly ready.

Virgin Galactic's SpaceShipTwo, billed as the world's first commercial space plane, notched an important milestone today by firing its rocket engine during flight for the first time.

The test at Mojave Air and Space Port in California saw the passenger space plane detach from its dual-hull mothership, WhiteKnightTwo, at an altitude of 47,000 feet while being piloted by Mark Stucky and Mike Alsbury of builder Scaled Composites.

The pair then ignited the rocket motor, which propelled the craft up to 55,000 feet. During the 16-second engine burn, SpaceShipTwo went supersonic, hitting Mach 1.2. … Read more

Last month at SXSW, SpaceX founder Elon Musk showed off a video of the SpaceX Grasshopper rocket rising 24 stories into the air and returning safely back to the ground. For a vehicle that is 10 stories high, that's pretty good, but not enough to make your jaw drop.

This creation is called the Grasshopper Vertical Takeoff Vertical Landing (VTVL) vehicle. It's so named because of its nifty parlor trick of being able to blast off vertically and then land upright. Now, the company has tripled the distance of the previous attempt and released a new video showing off the rocket's capabilities. … Read more

Believe it or not, there are still parts of the U.S. that don't have access to high-speed Internet. But that's looking to change with the onset of TV white-space broadband technology.

The first commercial application of this type of service in the U.S. is coming to a rural area of Northern California called El Dorado County, or Gold Country. Internet provider Cal.net is partnering with network equipment provider Carlson to bring this region's residents something more than dial-up.

"Over 59,000 residents in our rural service area have had little or no quality … Read more

Finding outside storage to back up computer files is critical in the event of a technical problem. CrashPlan for Mac is a well-designed program and cloud service that performs its function as a data storage application.

CrashPlan for Mac is available as a free application, but the cloud backup service is free for 30 days. After that time, users must sign up for a subscription service based on the amount of storage needed and the number of computers they'd like to run the app on. The program's native installer quickly set up the program. The program's main … Read more

After multiple scrubbed launches last week, an Antares rocket finally lifted off the ground from NASA's Wallops Flight Facility in Virginia as part of Orbital Sciences' bid to transport cargo to the International Space Station.

The rocket lifted off at 5 p.m. ET Sunday and achieved orbit smoothly. It launched an 8,400-pound mock Cygnus supply ship into orbit about 158 miles above Earth.

Antares is a medium-class, two-stage, 13-storey rocket designed to carry payloads of up to 6,500 kg (14,329 pounds). Along with SpaceX, Orbital was awarded a Commercial Orbital Transportation Services (COTS) contract to … Read more
