The rover Opportunity took this false-color photo of another possible stony meteorite dubbed “Marquette Island” on Monday December 7. These objects stand out on the barren sandy plain that Opportunity is currently traveling across on its way to Endeavour Crater and provide interesting targets for investigation. The rover has already used its Rock Abrasion Tool (RAT) to peek beneath the surface of Marquette.
The circular scar of the RAT can be seen above on the upward-facing left side of the rock.
First called “Sore Thumb” by mission scientists because of how it sticks out on the plain like…..well, a sore thumb, it has since been renamed according to the recently-established trend of naming such objects after islands here on Earth.
Opportunity’s tire tracks can be seen in the top left of this image as well.
