This incredible photo from the rover Opportunity pictures the Endeavor crater rim. It’s truly amazing how that even 12 years after being sent, Opportunity is still sending back photos this amazing.
Opportunity is the longest-running Mars Rover, having been exploring and taking pictures of Mars since 2004. Opportunity has been documenting mineral samples, craters, and even the discoveries of the existence of water since it embarked. Having many difficulties, including being stuck inside of a sand dune for several weeks, the rover is still moving, and sending images similar to the one above.
