A Brief Rotation of Mount Olympus © Avani Soares (Brazil)
"A series photos of Mars taken between 1 June and 3 July 2016 showing Mount Olympus in three different positions. Mount Olympus also known as Olympus Mons is the tallest volcano in the Solar System. The features on the surface of Mars as seen from Earth change rapidly, as seen in the contrast between the central photo, made during the opposition (when Mars is at its closest to the Earth), and the photo on the left, taken 33 days later."
