Take the rover for a spin around a virtual Mars crater

We've been exploring ways to immerse yourself in Mars without having to sign up for an experimental one-way space trip. You can play with a photo panorama, but you can also put yourself in Curiosity's shoes and take the rover for a crater ride.

NASA's Explore Mars: Free Drive online experience puts you in command of the rover in a virtual version of the Gale Crater on Mars.

It's fun to watch the rover's wheels react to the landscape. I made mine do doughnuts. There are plenty of points of interest available for exploration, including the landing site, a series of fractures, a canyon, sand dunes, and a phyllosilicate trough.… Read more

Geology rocks! New photos from Mars (pictures)

It was just a week ago NASA's Mars rover Curiosity landed on the surface of Mars, and began transmitting high-resolution images of the stunning landscape from the landing site inside the Gale Crater. New color mosaics from the Mastcam show the geological environment around the rover, including layers of cobbles and pebbles embedded in a finer matrix of material, as well as a network of fluvial valleys believed to have been formed by water erosion. Click the images to see the full-sized photos from the surface of Mars. (And when you're done viewing a full-size version, scroll to … Read more

Obama to NASA: I want to know about Martians right away

With the Olympics still in midstride, and with the arrival of the always exciting NFL exhibition games, you might perhaps have missed that a spacecraft landed on Mars a few days ago to express our human curiosity.

President Obama, however, has made it very clear that, should little beings be found out there, they will immediately become his top priority.

Indeed, in a phone call today with the Curiosity team, the President revealed that the first question he is being asked about the mission is whether Martians have already been found.

One can imagine that, even if they had been … Read more

Interactive Mars panorama: As close as you'll get to being there

My brother sometimes threatens to run away and join the eventual one-way human mission to Mars. He can get a better idea of what would await him by checking out an interactive, panoramic view of the planet as seen by the Curiosity rover.

Panographer Andrew Bodrov posted an explorable image of Mars to 360Cities. This is what it would it would look like if Google had been able to attach a Street View camera to the rover.

You can zoom and rotate the image to get a detailed, immersive view of the rocky surface, horizon, and the rover itself. It's the next best thing to being there, but without the crushing cold and lack of oxygen.… Read more

Slow, but rugged, Curiosity's computer was built for Mars

The electronic brain controlling NASA's Curiosity Mars rover has far less horsepower than the microchips typically found in a modern smart phone.

But the RAD750 PowerPC microprocessor built into the rover's redundant flight computers has one enormous advantage: It was engineered to be virtually impervious to high-energy cosmic rays that would quickly cripple an iPhone or laptop computer.

The radiation-hardened single-card computers, built by BAE Systems in Manassas, Va., are designed to withstand charged ions and protons in interplanetary space or on the surface of Mars that can physically damage integrated circuits or trigger so-called "bit flips&… Read more

iPhone has a better cam than Curiosity

Friday's top headlines won't judge you by your megapixels:

The Curiosity Mars rover cost $2.5 billion, so why are the cameras just 2 megapixels? The answer comes down to time: Time the rover was planned, the time it takes NASA to test, and the time it takes to transmit larger file sizes.

As Apple and Samsung duke it out in court over patents and copycat claims, Google isn't sitting back quietly. CNET has learned that Google is quietly helping out it's Android partner Samsung with legal advice.

Not all NASA news this week has been … Read more

Apple calls Samsung a copycat in court

Apple is using Samsung's own words against it in their high-stakes patent-infringement trial.

Apple pointed to an internal Samsung document highlighting the weaknesses of the Galaxy S1 compared with the iPhone as further evidence that Samsung has copied its work. The document, a "relative evaluation report" on the Galaxy S1 and iPhone published in March 2010 and unearthed by Apple, highlights where Samsung's flagship phone fell short of the iPhone.

Apple will draw on this document as proof that Samsung actively compared its products against the iPhone, and made strides to better mimic the blockbuster device. … Read more

Friday Poll: Will the Mars rover find signs of life?

The 1976 Viking mission to Mars uncovered some tantalizing, and much-debated, evidence of possible previous life on the big, red planet. Now we have the Curiosity rover over there to really sort things out.

Among other adventures, Curiosity is looking for organic molecules. The discovery of organic compounds could indicate previous life on Mars, though that life isn't likely to look like a toothy, long-headed alien that wants to hug your face.

While we wait for the rover to wander around and report back on its findings over the course of its mission, we have plenty of time to speculate about what it might find. … Read more

Curiosity prepped for software upgrade; snaps panorama

Engineers are gearing up to flush entry, descent and landing software from the Curiosity rover's central computer and replace it with programming optimized for surface operations, mission managers said Thursday.

In the meantime, the rover has snapped its first 360-degree color panorama of its surroundings in Gale Crater and beamed down an initial set of low-resolution thumbnail frames that provide a hint of things to come. The full-resolution frames will be eight times sharper than the thumbnails, but they must be moved from the camera's memory to the main computer for later relay to Earth.

Frames from a … Read more
