Engineers troubleshoot Curiosity computer glitch

Space radiation may be to blame for corrupted memory used by the Curiosity Mars rover's flight computer, resulting in software glitches that interrupted the flow of science data Wednesday and prompting ground controllers to switch over to a back-up computer Thursday, NASA officials said.

Engineers are reviewing telemetry and diagnostic tests using ground systems to figure out what went wrong and how to restore the original computer system to normal operation.

"We were in a state where the software was partially working and partially not, and we wanted to switch from that state to a pristine version of … Read more

SpaceX supply ship prepped for Friday launch to station

SpaceX engineers readied a Falcon 9 rocket for a launch tomorrow on the company's second operational space station resupply mission, a commercial flight to deliver more than 2,300 pounds of science gear, station equipment, spare parts, and crew supplies to the international lab complex.

If all goes well, the unmanned Dragon cargo ship will return to Earth on March 25 loaded with some 3,000 pounds of no-longer-needed hardware, broken components, and experiment samples bound for laboratory analysis.

"Quite a bit of work has been done to get to this point, by the SpaceX team, by the … Read more

Using space telescopes to measure black hole distortion

An innovative X-ray telescope operated by NASA, working in concert with a European Space Agency satellite, has directly measured the rotation of a supermassive black hole lurking at the heart of a distant galaxy, researchers said Wednesday.

The observation confirms predictions made by Albert Einstein's theory of general relativity regarding gravity's ability to twist and distort the fabric of the cosmos and gives astronomers a powerful new tool to probe the evolution of galaxies and the black holes that now appear to be a common, if not required, feature.

"The result we're announcing today is that … Read more

Man-and-woman Mars trip by 2018? Can you say 'couples counseling'?

A wealthy space tourist announced plans today to launch a high-risk manned flight to Mars in 2018, sending a man and a woman on a bare-bones 501-day round-trip flyby, passing just 100 miles above the Red Planet before heading back to Earth.

Dennis Tito, the first private citizen to fly aboard the International Space Station, said he will provide two years of funding to support the Inspiration Mars Foundation, a nonprofit he started to execute the proposed venture. Additional money will be raised from private sources.

"We have 50 years of experience," he told reporters during a news conference. "We can do things a lot faster, we just need a commitment. I'm not worried about getting this done from that standpoint. The vehicles are there, we have time to get it together."… Read more

Canada orbits suitcase-size camera to hunt asteroids

Aside from giant laser beams, can eyes in the sky help save us from asteroid hits?

Canada thinks so, and it has launched a space telescope to track hazardous objects including asteroids, space junk, and satellites.

The Near-Earth Object Surveillance Satellite (NEOSSat) was launched from an Indian rocket this week as the first dedicated space-based sentinel of its kind.

Managed by the Canadian Space Agency (CSA) and Defence Research and Development Canada (DRDC), NEOSSat is about the size of a suitcase and orbits some 500 miles above Earth, circling every 100 minutes. … Read more

Google Nexus fired into space to see if screams are audible

One of the all-time best sci-fi film taglines is to be put to the test. Is it true that "in space no one can hear you scream"?

You could survive exposure to the hard vacuum of space for several seconds, long enough to attempt a yell or yodel. After that, however, bad things will happen.

But thanks to some British boffins at the University of Surrey's Surrey Space Centre and Surrey Satellite Technology, humanity doesn't need to test the "Alien" tagline firsthand. They've launched a satellite into orbit equipped with a screaming smartphone. … Read more

Trekkies conquer contest to name Pluto moons

Earlier this month, astronomer Mark Showalter and the SETI Institute asked the Internet to help name two Plutonian moons. The results are in after 450,324 votes from around the world on the Web site Pluto Rocks.

Pending authorization from the International Astronomical Union, the new names for Pluto's smallest moons -- currently called P4 and P5 -- could end up changing to Cerberus and Vulcan.… Read more

Mars, the Red Planet, is actually pretty drab underneath

Mars has established a pretty pervasive image for itself. It's the big Red Planet. It's the Clifford the Dog of space. You don't confuse it with all those other, less glamorous, planets. Still, Mars isn't all that it seems. Scratch the surface and it appears to have more in common with the skin tone of an elephant than the ruddy glow of a tomato.

The Curiosity Rover recently broke new ground by drilling into a rock sample, the first time such an activity has been accomplished on a planet other than Earth. What lay beneath wasn't the familiar rust color of the surface, but a decidedly dull gray.… Read more

New titleholders to vye for crown of fastest spacecraft ever

Of all the spacecraft humans have launched, there have been some impressively fast movers. But which holds the record?

It's not an entirely idle question. Apart from the wow factor, it's an interesting yardstick for gauging our capacity to explore the cosmos, from familiar planets to the icy depths of space.

However, as I quickly discovered in writing this post, it's not always an easy quantity to evaluate. For one thing, launch velocities differ from eventual cruise velocities. And fancy interplanetary maneuvers like the " gravity assist" can provide temporary speed boosts that have to be … Read more
