Interactive panorama of Curiosity photos lets you take hi-rez Mars-walk

A stunning 4-gigapixel panorama of Mars, compiled from images captured by two mast cameras aboard NASA's Mars Science Laboratory Curiosity rover, could be one of the most detailed views of our distant neighbor yet.

The panoramic picture of Gale Crater derives from 295 images that were digitally stitched together by Estonian photographer Andrew Bodrov. In its final form, the mosaic stretches out to an astounding 90,000 by 45,000-pixel resolution. … Read more

Solar plane to embark on coast-to-coast U.S. tour

The Solar Impulse has defied all expectations in its short four-year life.

First, the solar-powered airplane got off the ground in 2010 and stayed aloft for a total of 87 minutes without using a drop of fuel; then, it completed its first international flight traveling from its home of Switzerland to Brussels in about 13 hours. By its first birthday, the plane met the goal of staying aloft for 24 hours -- flying at night with solar energy captured during the day. It has since completed a 1,550-mile journey from Madrid, Spain, to Rabat, Morocco.

Now, before it embarks … Read more

Behind-the-scenes: NASA's Nexus-powered drones

You could call them drones, or satellites -- NASA prefers the latter -- but these small flying robots that are being used on the International Space Station are powered by Nexus S smartphones.

Ars Technica has a lengthy writeup on how the space agency hacked smartphones to power its SPHERE (Synchronized Position Hold, Engage, Reorient, Experimental Satellites) satellites after their original CPUs had become too slow for their needs. Modern handsets made sense since they have integrated cameras, sensors, Wi-Fi connectivity, and of course, a capable processor. … Read more

Was that a meteor over New York (and zipping across Twitter)?

Apparently the bright object that people reported seeing shooting over the East Coast of the United States last night -- and that left a glittery trail across Twitter -- may well have been a meteor.

Bill Cooke of NASA's Meteoroid Environmental Office told the Associated Press that, "going on visual reports," the flash was "a single meteor event."

"The thing is probably a yard across. We basically have (had) a boulder enter the atmosphere over the northeast," he added.

The object lit up Twitter last night at about 8 p.m. East Coast … Read more

Bezos Expeditions recovers pieces of Apollo 11 rockets

A year after discovering rockets from the Apollo 11 moon mission on the bottom of the Atlantic Ocean, Bezos Expeditions has recovered "many prime pieces" of the engines, Jeff Bezos blogged today.

Amazon's billionaire founder and chief executive wrote that the crew of the ship Seabed Worker spent three weeks at sea, working almost three miles below the surface to pull up the various piece of the engines.

"We've seen an underwater wonderland -- an incredible sculpture garden of twisted F-1 engines that tells the story of a fiery and violent end, one that serves … Read more

What if a meteor heads toward NYC? NASA says 'pray'

At a House Committee hearing today, NASA administrator Charles Bolden Jr. was asked what America would do if a meteor similar to the one that hit in Russia on February 15 was found to be on a path toward New York, with impact three weeks away. His response? "Pray."

At the moment, we might be lucky to get even three weeks' warning. The United States and the rest of the world simply do not have the ability to detect many "small" meteors like the one that exploded over Russia, which has been estimated at roughly 55 … Read more

Sex in space may be dangerous, study says

I've always imagined that being up in space isn't really so much fun.

Yes, the views are nice, but the claustrophobia must be entirely stifling. What are you supposed to do up there, for days on end? You can't just work all the time.

The temptation, then, might be to occasionally enjoy a little recreation in the procreative sphere.

Sex would surely offer a touch of vigorous exercise and a little human community.

However, now research has emerged suggesting that sex up there could be dangerous.… Read more

Space shots: Our beautiful world from far above

Today, the International Space Station gets a change of command as outgoing NASA Commander Kevin Ford transfers leadership of the space lab to Commander Chris Hadfield, the first Canadian astronaut to assume the role. Hadfield and crew will carry out the planned Expedition 35 mission (PDF).

Our gallery below looks back at some the extraordinary images of Earth Hadfield captured with dSLRs during his first few months aboard the space lab (he and Expedition 34 arrived in mid-December). The unique vantage point of the ISS delivers unforgettable vistas, from the astoundingly abstract Australian Outback to a sensational shimmer of gold on the waters of the San Francisco Bay.… Read more

Curiosity Rover discovers conditions suited for ancient life on Mars

NASA is reporting that an analysis of a rock powder sample collected by the Curiosity rover suggests that ancient Mars could have supported living microbes.

The sample contained traces of sulfur, nitrogen, hydrogen, oxygen, phosphorus, and carbon -- key chemical ingredients for life.

For astronomers, the news constitutes the latest clue in their pursuit of a scientific holy grail: Answering the big question about whether life ever existed on the Red Planet. Their challenge until now has been to confirm whether the Martian atmosphere could have supported a habitable environment. The preliminary evidence now suggests the answer is yes, with the rock samples pointing to evidence that conditions on Mars were once favorable for life. A couple of particularly intriguing clues: The presence of clay as well as the absence of "abundant salt" point to the likely existence of an ancient environment where there was fresh water, according to NASA.… Read more
