A blog about science and movies.
Celebrating 15 years of robotic presence on the moon, NASA’s Mars Exploration Rover Opportunity sent this lovely postcard to back Earth (okay maybe a few things have been added).
It’s a panoramic image comprised of 817 pictures taken by the rover’s camera between December 21, 2011 and May 8, 2012 while camping for the Martian winter at an overlook called “Greeley Haven.” The photo, which has been false colorized to “emphasize differences between materials,” shows tracks from the rover, an ancient impact crater, and the solar decks of the rover itself.
Roving robots first arrived to the Red Planet on July 4, 1997 with the Mars Pathfinder; Opportunity and its twin Spirit got there in 2004. They’ll soon be joined by the next-generation rover, named Curiosity, set to land next month.
