Perhaps the Red Planet isn't quite so red as we thought. NASA's Curiosity rover has been digging up some unusual bits in the soil of Mars. A couple weeks ago, the rover found a strange bright object which later turned out to be a part of the rover itself. Now we have a new mystery object to contend with.

Curiosity took a few scoops of Martian soil from a patch called "Rocknest." That activity uncovered a bright particle in the pit it created. Unlike the earlier object, NASA has confirmed the new piece is of Martian origin. There are others like it scattered around.… Read more

It looks like the latest Mars mystery has been solved. Dashing the hopes of the many people who thought the Curiosity rover had located their lost keys or earrings, NASA has decided that a strange, bright object found on the surface is actually a piece of plastic.

According to a NASA status report, "The rover team's assessment is that the bright object is something from the rover, not Martian material. It appears to be a shred of plastic material, likely benign, but it has not been definitively identified."… Read more

Much like a toddler in a sandbox, the Curiosity rover has been busy scooping up the Martian soil lately. All that digging around was brought to a halt by the discovery of a small, bright object. NASA is currently trying to sort out what it is.

According to NASA, "Curiosity's first scooping activity appeared to go well on October 7. Subsequently, the rover team decided to refrain from using the rover's robotic arm on October 8 due to the detection of a bright object on the ground that might be a piece from the rover."… Read more

Columbus Day has attracted its share of detractors in recent years among indigenous peoples' groups and others. That's not to mention the widening recognition that Christopher Columbus ended up in the Americas through some remarkably bad navigational skills and then set about conquering its people through slavery, disease, and other little bits of nastiness.

Suburban St. Louis business owner Karl Frank Jr. has always had similar sentiments. While taking in media reports on the death of Neil Armstrong that compared the shy moonwalker to Columbus, Frank says a light bulb went off. He contacted a few nerdy friends and soon a petition was drafted to re-dedicate Columbus Day as "Exploration Day." … Read more

After creeping about 500 yards across the rocky floor of Gale Crater on the way to an intriguing intersection of different terrain types, the Mars Curiosity rover is pausing for a few weeks near fine-grained sand dunes to scoop up soil and run it through the vehicle's sample acquisition system to clean out any lingering traces of Earth's environment.

After three such "rinse and repeat" cycles, a scoop on the end of the rover's robot arm will deposit small samples into a pair of sophisticated laboratory instruments, the Chemistry and Mineralogy experiment, or CheMin, and … Read more

I know that some people adore Foursquare.

They have a dominant need to become the mayor of their local laundromat and fishmonger.

However, others feel safer when others don't know where they are. Indeed, last night I saw several attendees of Oracle OpenWorld wandering around a part of San Francisco's North Beach and entering places from which I feel confident they would not have checked-in.

NASA's Mars rover, Curiosity, has no fears however.

It is unconcerned about broadcasting its precise whereabouts. It has no worries that by doing so it might be vulnerable to a Mars attack.… Read more

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

NASA's Curiosity Mars rover has driven some 357 feet from its landing site on the floor of Gale Crater -- 269 feet as a martian crow might fly -- on its way to an intriguing area about five times farther away where three different types of rock come together. The rover continues to chalk up near perfect scores during extended checkout operations, with detailed robot arm tests on tap over the next week or so.

"We've been on the surface of Mars for about a month and Curiosity continues to be very healthy and continues to surprise … Read more
