The images were captured and compiled by NASA's Mars Exploration Rover Opportunity. They show the terrain that surrounded the rover while it was stationary for four months of work during its most recent Martian winter. MERO's Pancam took the photographs between Dec. 21, 2011 and May 8, 2012.
The images, while not exactly surprising, are still quite interesting. It's an odd thing seeing another planet in such detail, especially considering how close the planet resembles parts of ours. Here's hoping the next set of images capture a martian or two.
