NASA has found 3 nice, habitable planets for us to choose from

NASA, that wily band of intergalactic peepers, says it's spied three distant planets in two different solar systems that are the proper distance from their suns to make them potentially habitable.

I can almost hear Elon Musk's pitch for time-shares in the Kepler-62 and Kepler-69 systems already.… Read more

NASA's Kepler spacecraft to reveal new planetary discoveries?

NASA's Kepler spacecraft has been in hot pursuit of extraterrestrial life for four years now. And, on Thursday, it's letting people know just what it's found lurking in the Milky Way.

NASA is holding a Kepler briefing at 11 a.m. PT on Thursday. It will be broadcast live on NASA Television and on UStream. The agency will also host a moderated Web chat with Kepler Deputy Project Scientist Nick Gautier of NASA's Jet Propulsion Lab. During the briefing, people can submit questions to the Kepler scientists via Twitter with the hashtag #AskNASA.

NASA experimenting with 3D printing for space exploration

NASA is getting into the 3D printing business. At NASA's Ames Research Center, engineers and researchers are experimenting with the technology with the hope that one day their creations will be used in space exploration. "Space Shop is our attempt to take the best practices and lessons learned from what we call the maker community," said Dave Korsmeyer, the director of engineering at NASA Ames.

The program is still in its nascent stages. But NASA sees potential in the technology because it enables designers and engineers to get the manufacturing information early in the design process and … Read more

Boeing's futuristic X-48C makes final flight

It's mission accomplished for the experimental X-48C aircraft.

The distinctively shaped machine this week made the last of 30 flights in an eight-month program as backers Boeing and NASA sought to show how well a "blended wing body" aircraft can perform. The X-48C program is tied to NASA's Environmentally Responsible Aircraft project, which is geared toward developing futuristic airplanes that burn less fuel, spew fewer emissions, and make less noise.

The Boeing-designed X-48C has a radically different look than that of conventional aircraft. Where a big 747 or a little Cessna has -- very roughly speaking … Read more

Biggest solar flare of the year knocks out radio transmissions

Early this morning the sun erupted, sending billions of solar particles into space at over 600 miles per second, raising the prospect of solar radiation storms above the Earth, according to NASA. A spokesman said the resulting emissions sparked a short-lived radio communications blackout on Earth. The radio disruption has since subsided. The appearance of the strongest solar storm of 2013 is part of an increasingly common sight as astronomers say this is connected to the sun's 11-year activity cycle. More intense solar eruptions are expected later in the year.

High-speed cam catches cool 3D shots of snowflakes

Now that winter has passed, those of us who live in cold climes can once again appreciate the beauty of snowflakes without feeling the urge to curse them for making us dig out the shovel. And if ever snowflakes looked lovely, it's in these images shot by a high-speed camera system developed specifically to photograph them in 3D as they fell.

"Until our device, there was no good instrument for automatically photographing the shapes and sizes of snowflakes in free fall," says Tim Garrett, an associate professor of atmospheric sciences at the University of Utah and one of the developers of the cam known as MASC, or Multi-Angle Snowflake Camera. "We are photographing these snowflakes completely untouched by any device, as they exist naturally in the air."

MASC -- under development for three years -- takes 9- to 37-micron-resolution stereographic photographs of snowflakes from three angles while simultaneously measuring the speed of their fall, a highly influential factor in the location and lifetime of a storm. … Read more

NASA's plan to bag an asteroid wins place in Obama's budget

Turns out that crazy rumor was true: NASA is planning to capture an asteroid.

The plans were included in the space agency's $17.7 billion fiscal 2014 budget, part of the new $3.7 trillion government budget proposed earlier today by President Obama.

In the budgets, about $78 million is set aside for a plan that involves sending a craft to rendezvous with what's described as a "small asteroid," and then moving the space rock into a stable orbit near the moon. Astronauts will later visit the asteroid and scoop up samples for study back on … Read more

NASA to 'lasso' an asteroid

There could be a sequel in the works to that absurd scene from 1998's "Armageddon" in which Ben Affleck and friends land on a threatening near-Earth asteroid. But this time around it's a real-world NASA mission to kidnap, rather than obliterate, a space rock.

Part of the idea is to conduct research to help prevent just such an "Armageddon" scenario from ever cropping up in real life, according to a mission overview obtained by CBS News last week. The space agency is hoping to lasso an asteroid, space cowboy style, and tow it close enough to Earth so that it can be visited by astronauts. The astronauts then will conduct research that could one day assist in a mission to Mars or save Earth from a catastrophic collision, should Mr. Affleck be unavailable. … Read more

NASA puts Mars rover on a month-long hiatus

For the first time since its descent onto the red planet, the Mars rover Curiosity is getting a little alone time.

The rover and NASA scientists are having a communication breakdown, of sorts. But, not to worry, no hurt feelings are involved. The issue is that the sun has got in the way.

Once every 26 months, as the Earth and Mars rotate around the sun, the two planets end up on opposite sides of the star in an event called the Mars solar conjunction. Because of the sun's massive size, any communication sent between the two planets can … Read more
