Same object from a different camera...

is it just me that thinks, that them cables on the mars rover look exposed, IE its 2012 why couldn't they come up with something better, than just a bunch of wires cable tied together, i know they are probably reinforced cables, but still why couldn't they put some trunking round them. maybe they did and had to remove it due to weight restrictions. seems bad planning since you can supposedly get gusts of wind up to 300mph on mars.

The Curiosity rover is stopping its sampling of soil from the surface of Mars because of a shiny object noticed on the ground.

A photo released by NASA and the Jet Propulsion Laboratory of Curiosity's first scoop of Martian soil also revealed a bright object nearby.

The planned sampling has been stopped so that scientists can get some additional images of the unknown object and assess any impact on the rover's activities.

"The object might be a piece of rover hardware," the JPL caption to the photo noted.

When word of the mysterious item on the surface spread, Twitter commenters, of course, chimed in with their guesses: a lost earring, a cigarette butt, a screw that came loose, Martian macaroni or some unusual chunks of sand.

[Photos: Curiosity rover explores Mars (updated)]

The official @MarsCuriosity account tweeted, "Team spotted bright object on ground near me—possibly a piece of rover hardware? Gathering more data."

A more detailed picture from Curiosity's ChemCam imager seemed to indicate it was possibly some plastic wrap or a small piece of insulating tape that is used around the rover, the Planetary Society's Emily Lakdawalla told NBC News.

If it is a piece from Curiosity, it would just add to the many things the rover is leaving on the fourth planet from the sun during its $2.5 billion mission.

Among the things the mobile explorer, which is looking for evidence of past microbial life on Mars, has left on the red planet are a wheel print and some laser holes.

Oh, and then there are those odd spidery black objects that scientists say could be Martian microorganisms.

Could this shiny silvery thing be their tiny mothership?

Nah.

Once more data pours in, NASA I'm sure will have some logical explanation for what the bright shiny object really is.

It was expected to be just another lump of dull basalt, but the first rock examined up close by Nasa's Mars rover proved to be a little more interesting.

The pyramidal object, nicknamed "Jake Matijevic" after a recently deceased mission engineer, had a composition not seen on the planet before.

Scientists have likened it to some unusual but well known rocks on Earth.

These form from relatively water-rich magmas that have cooled slowly at raised pressures, said Edward Stolper.

"[The rock is] widespread on Earth, on oceanic islands such as Hawaii, and St Helena, and the Azores; and also in rift zones like the Rio Grande and so forth. So, again, it's not common, but it's very well known," the mission co-investigator from the California Institute of Technology, Pasadena, told reporters.

The Curiosity rover examined Jake Matijevic three weeks ago. At the time, the dark rock was not anticipated to have high science value; it was merely an early opportunity to use the robot's survey instruments in unison.

Jake Matijevic also had an interesting, weathered appearance that drew attention.

The rover first zapped the rock from a distance with its ChemCam laser, and then moved in close to study it with its X-ray spectrometer known as APXS. The latter device is held on the end of the rover's robotic arm; the laser is mounted on its mast.

Jake Matijevic was found to be high in elements consistent with the mineral feldspar, such as sodium and potassium, and low in elements such as magnesium and iron.

Prof Stolper compared the signatures with a catalogue containing thousands of Earth rocks, and determined the nearest match to be an igneous type, the formation of which he likened to the production of colonial apple jack liquor.

This saw barrels of cider left outside in winter to partially freeze. As the barrels iced up, they would concentrate the apple-flavoured liquor.

A similar process was occurring in the liquid magma several kilometres underground that gave rise to alkalic rocks like Jake Matijevic, said Prof Stolper.

"In the case of the apple jack, you take out water and concentrate alcohol; in this case you take out particular minerals - olivines, pyroxenes and some feldspars - and you generate a liquid that is very different to what you started with," he explained.

"So, the composition of Jake Matijevic is a very close match to highly crystallised or fractionated magmas that occur in particular places on Earth."

Curiosity landed in Mars' equatorial Gale Crater in August, and has driven eastwards almost 500m since then.

It is currently stationed just short of a point called Glenelg, where satellite images have revealed a juxtaposition of three different types of terrain.

Scientists expect this location to be a good starting point to begin characterising the geology of Gale.
Scoop The rover is scooping dirt to scrub its system for handling and sorting samples

The mission is going through something of a lull presently while the rover spends a few days preparing its sample handling system.

It is running dirt through this equipment to scrub surfaces free of any residual contamination from Earth.

This is necessary to avoid skewing the analyses of rock and soil samples delivered to the rover's onboard laboratories later in the mission.

Curiosity's goal is to try to determine if Gale ever supported environments that might have allowed microbial life to flourish.

In the short time it has been on the ground, it has already identified rocks that were clearly deposited in fast running water. The theory is that the rover is sitting at the head of an ancient alluvial fan where a network of streams cut across the crater floor billions of years ago.

From the video we can learn two things about the anomaly in the photo above.
1) NASA really doesn't know for certain what exactly it is.
2) They don't care enough about it to scoop it up and analyze it further...so we'll never know either.
