Latest Curiosity image perhaps best yet

It's as if you've just strolled up to Curiosity on the surface of Mars and surprised the rover as -- convinced that everyone at Mission Control is on a coffee break -- it's decided to ditch the scientific research for a bit and build a martian sand castle instead.

One of the latest Curiosity images posted by NASA is a stunning self-portrait made up of 55 high-rez images taken by the rover's Mars Hand Lens Imager. The base of Mount Sharp serves as a dramatic backdrop, swooping up toward the right, and in front of the rover, you can see four hand-size holes in the ground where Curiosity had just started building its sand castle gathered scoops of martian dirt for analysis. The scoop site is poetically named "Rocknest."… Read more

Pay $7 to promote your Facebook status?

Thursday's CNET Update never forgets a face:

Today's tech news roundup begins with a look at Facebook. The network is testing a feature that lets you pay to get your posts seen by more friends. Facebook first began testing this concept in May and it's already in 20 other countries. But it's rolling out to some U.S. users now, and the idea is to pay to show off big news or get more attention to an event. Facebook hasn't set an official price for this, but CNET staffers with the feature are asked to … Read more

Curiosity snaps photo of partial solar eclipse -- from Mars

Seeing as Mars is much further away from the sun than Earth is, a solar eclipse would look different than it does here. Curiosity -- NASA's Mars rover -- caught an image of what this phenomenon looks like from the Red Planet.

While somewhat less impressive than what a solar eclipse looks like from Earth, appearing as a tiny black blip on a small white blip, this photo is still fascinating. Mars has two moons that orbit it, so the moon seen in this image is called Phobos.

To get this photo, Curiosity -- ever the clever rover -- … Read more

Curiosity fires ChemCam laser for first time on Mars

On August 19, 2012, NASA's Curiosity rover used the ChemCam, its laser-camera combo unit, for the first time on Mars, firing an energy beam at a small rock called "Coronation."

Having excited the atoms in a target rock into an ionized, glowing plasma with its million watt laser, ChemCam can then use its telescopic camera to watch the light emitted and analyze it with three spectrometers for information about elemental composition.

This first firing of the laser was primarily for target practice and calibration, but the ChemCam team expects to eventually take about a dozen compositional measurements … Read more

Game not over yet for OnLive

Any objection to Monday's top tech headlines is overruled:

The Apple vs. Samsung trial is almost at a close. The jury is expected to begin deliberations Tuesday. The two tech giants spent three weeks battling over patents and accusations of copying.

OnLive is facing some rough days ahead. The cloud-based gaming service sold its assets to an investor Friday and laid off employees, but said it will rehire many back as the newly restructured company (which will still be called OnLive). The company says subscribers shouldn't see any problems or interruptions in service during this restructuring.

Mars Curiosity rover team prefers Macs to PCs

If there was anything Curiosity fans wanted to know about Mars, the rover, and the scientists behind the Martian landing, they were able to ask it today.

Reddit hosted a lengthy "Ask us Anything" Q&A with 12 members of NASA's Mars Curiosity Rover science and engineering team. And, yes, it included the "Mohawk guy."

Dozens of topics were covered, from whether there is life on Mars to how far Curiosity will roam within the Gale Crater to specifications of the equipment on the rover. At the time of this writing, there is a … Read more

Take a virtual tour of Mars on your iPhone or iPad

If you've been following the Curiosity rover's progress even a little, you've probably seen the cool 360-degree Mars panorama that hit the Web a couple days ago.

As CNET's Amanda Kooser pointed out, it's "about as close as you'll get to being there."

Now you can get even closer, virtually speaking. It turns out that the panorama works with gyroscopes, meaning that if you view it on your iPhone or iPad, you'll get a much more interactive experience.

Stop listening to me describe it and go do it:

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.

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
