After a long hiatus, Mars Express' Visual Monitoring Camera returned to work on Leap Day, 2016, taking a photo of Mars in late northern summer. The bright feature at the top is the north polar cap. At center right is the Elysium volcanic complex. Gale crater, home to the Curiosity rover, is visible to the south of Elysium. This is a stack of three VMC images, enlarged to 150% of the original size.
