Two weeks ago, NASA’s Opportunity Rover discovered the largest meteorite yet observed on Mars. Sure, any space debris can be an exciting discovery, but the rock’s size has its own cool implications: Mars’s atmosphere used to be a lot thicker.
The rock, dubbed “Block Island,” is approximately 2 feet long and has a blue tint. The rover took a picture of the formation in passing two weeks back, but the Rover team decided that Opportunity should backtrack and do some more tests on the relatively giant space rock.
