Curiosity Rover Just Spotted This Super-Shiny Object on Mars

An unusually smooth and reflective Martian rock has caught the attention of NASA scientists, prompting an investigation by the Curiosity Rover.

With the spectacularly successful landing of the InSight probe on Mars earlier this week, our attention has understandably been diverted away from Curiosity, which has been exploring the Red Planet since 2012. While we’ve been gushing about InSight, the six-wheeled NASA rover has been working at Vera Rubin Ridge, investigating the Highfield Outcrop, a unique patch of gray bedrock. 19659002] Curiosity has been to the Highfield drill site before, but NASA’s mission controllers wanted to take a look at four previously detected rocks-including an unusually smooth rock that, at least in black and white, looks a bit like a chunk of gold.

Immediate suspicions are that the rock, dubbed Little Colonsay, is a meteorite, but NASA scientists will not know for sure until Curiosity performs a chemical analysis. The rover’s ChemCam instrument, which consists of a camera, spectrograph, and laser, offers an on-the-spot chemistry lab.

That Curiosity may have stumbled upon a meteorite is not shocking. The rover has sniffed out several such objects over the course of its travels, including a huge metal meteorite in 201

5 and a shiny nickel-iron meteorite the following year.

Other interesting objects discovered by Curiosity include a seemingly out-of-place Shard, a smooth, oddly shaped object that turned out to be a piece of plastic wrapper that fell from the rover, and a perfectly-looking sphere determined to be the product of a natural geological process called concretion. Perhaps the weirdest incident happened in 2013, when Curiosity spotted rocks that bore a startling resemblance to a squirrel-a classic example of pareidolia, a kind of optical illusion in which faces, animals, or everyday objects are projected onto insignificant stimuli or mediums. 19659002] Anyhoo, the Curiosity Rover will also investigate a rock called Flanders Moss, which earned its name due to its dark-colored coating. Again, NASA will not know more about this object until Curiosity analyzes a sample after drilling. Two other rocks, Forres and Eidon, will also be investigated before Curiosity bails on the Highfield site.

Sadly, Curiosity is the only mobile rover on Mars at the moment. Its compatriot, the Opportunity Rover, has been out of commission since a dust storm forced it into hibernation mode, a sleep from which it has been unable to awaken. NASA has not declared the mission dead just yet, but we should know more about the status of Opportunity early next year. [NASA JPL]
