The Hubble Space Telescope captured this view of the planet Mars between April 27 and May 6, 1999 (the middle of Martian northern summer), when the Red Planet was about 54 million miles (87 million kilometers) from Earth. Surface features as small as 12 miles (19 kilometers) across are visible, including numerous craters, cloud-shrouded volcanoes, and a massive cyclonic storm churning near the north polar ice cap.
Four sets of Hubble telescope images, taken with the Wide Field and Planetary Camera 2, were mapped and projected onto a sphere to create this animation of a rotating Mars.
