Mars at opposition in February 1995 (HST). Caption: Three views of Mars from the Hubble Space Telescope on 25 February 1995, giving global coverage of the planet, which was 103 million km (65 million miles) away. It appeared cloudier than in previous years. Details as small as 50 km are resolved. In the Tharsis region view, the crescent shaped cloud right of center lies over Olympus Mons. The Valles Marineris is visible in the central image at the lower left. In the right-hand view, the dark area protruding northwards left of center is Syrtis Major Planum. There are clouds over the volcanoes of the Elysium region on the east side (right). Copyright: Credit: Philip James, Steven Lee and NASA
