International Space Station springs system coolant leak

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

Landsat watches over the Earth, documenting 28 years of change

NASA's Landsat 5, which recently set a Guinness World Record for the "Longest Operating Earth Observation Satellite," has been delivering high-quality, global data of Earth's land surface for 28 years and 10 months.

Using the annual Landsat satellite imagery captured since 1984, Google has created dramatic composites, alongside other Google Earth satellite imagery, depicting our changing world, the death and growth of natural lands, and humans' impact on the landscape.

The animated GIFs shown here chronicle the development and destruction of life on Earth, pulsing like a living being, with forests receding, water evaporating, and cities … Read more

Time-lapse images let you witness 28 years of Earth's changes

A newly released series of dramatic time-lapse satellite images, available at Google's Timelapse Web site, shows just how quickly the world's landscapes have changed in the last 28 years.

The pictures, captured by the series of Landsat satellites and released in conjunction with the U.S. Geological Survey, NASA, and Time magazine, show several startling examples of how humans and natural processes have changed Earth from 1984 to 2012. You'll see the depressing decline of the Columbia Glacier in Alaska, the blossoming of Dubai's epic cityscape, and Las Vegas' urban explosion. There's also an alarming look at the deforestation occurring in the Brazilian Amazon forest. … Read more

Fiery annular solar eclipse to be broadcast live on Internet

It's that time again where certain people on Earth are lucky enough to see an annular eclipse, or "ring of fire."

People on the ground in much of Australia, Papua New Guinea, and the Solomon Islands will be able to gaze toward the sky Thursday evening and witness the eclipse. However, the rest of us, who aren't in that part of the world, can watch the action live on the Slooh SpaceCamera Web site via an Australia-based telescope.

An annular eclipse is no ordinary eclipse; it's a rare and spectacular occurrence. Rather than a complete … Read more

Relive Earth's wild history of meteor strikes

Aside from death and taxes, there's another thing certain in life: meteors. To get a historical perspective on just how many dazzling space rocks have fallen through our skies in recent times, peep at Carlo Zapponi's visual graph called Bolides, which puts meteor strikes in a chronological view.

Inspired by the Greek word bolis (missile), Bolides features data from a range of historical meteor records, ranging from MetBase to London's Natural History Museum catalog of meteorites, and displays the data in a way that makes you want to click around and explore. … Read more

NASA's asteroid lasso mission said to halt Apocalypse scenario

Shortly after a large meteor hit Russia in February, injuring about 1,000 people, President Obama's administration announced that the U.S. would work on asteroid tracking technology to avoid potentially more severe Earth collisions. On Monday, top NASA administrator Charles Bolden reiterated this pledge.

Bolden spoke at the Human to Mars Summit in Washington, D.C. on Monday and said that a robotic spacecraft mission currently being planned will "prepare efforts to prevent an asteroid from colliding with devastating force into our planet,"according to U.S. News & World Report.

The government's plan is … Read more

Neil Armstrong's moon walk EKG reading up for auction

We've all seen the video of man's first step on the moon. NASA's medical team back down on Earth saw that first step in a slightly different light, in the form of Armstrong's electrocardiogram reading from the moment he set his foot down. That little 6-inch strip is going up for online auction at RR Auction.

The strip comes in a presentation frame along with an Armstrong autopen signature and various mission patches. "After the landing, this EKG report was saved by the Manager of Medical Administration for the Space Center. It was cut up into five pieces; four were presented to the attending physicians on the medical team," reads the description.… Read more

Meteor shower created by Halley's Comet to peak Sunday

The meteor shower created by the debris trail of Halley's Comet will peak Sunday evening, and NASA is providing a live view of the celestial fireworks show.

Prime viewing of the annual Eta Aquarid meteor shower should be around 9 p.m. ET, providing stargazers with 30 to 40 meteors an hour, according to NASA. A camera at NASA's Marshall Space Flight Center in Hunstsville, Ala., will provide live video of the event from 8 p.m. ET to 3 a.m. ET Monday (see below).

The space agency will also host a live chat with Bill Cooke, … Read more

Helping 'Star Wars' newbies finally embrace the Force

SAN FRANCISCO--What I'm about to tell you is 100 percent true, no matter how much you will want to tell me I'm full of it: there are American adults who have never seen "Star Wars."

The 1977 George Lucas film is a timeless global phenomenon and may be one of the most embedded of all our cultural artifacts. It spawned an empire that Disney ended up buying for $4 billion, in large part because of the passion and commitment of its worldwide audience. But still some people, even those who watch other movies, and are part of mainstream society, managed to make it to 2013 without ever seeing it.

For one group of "Star Wars" newbies, though, their lifelong exclusion from one of the biggest clubs on Earth is over. … Read more

Super tool: Canada enshrines robot space arm in museum

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
