好奇號剛在火星上發現這使科學家困惑的不尋常地光滑並且超耀目物體
Curiosity Rover just spotted this unusually smooth and super-shiny object on Mars baffling scientists

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 over InSight, the six-wheeled NASA rover has been working at Vera Rubin Ridge, investigating the Highfield outcrop, a unique patch of grey bedrock.

Curiosity has been at 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, in black and white at least, looks a bit like a chunk of gold.

Immediate suspicions are that the rock, dubbed Little Colonsay, is a meteorite, but NASA scientists won’t 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.
