Taking advantage of Mars's closest approach to Earth in eight years,astronomers using NASA's Hubble Space Telescope have taken thespace-based observatory's sharpest views yet of the Red Planet. NASA isreleasing these images to commemorate the second anniversary of the MarsPathfinder landing. The lander and its rover, Sojourner, touched downon the Red Planet's rolling hills on July 4, 1997, embarking on anhistoric three-month mission to gather information on the planet'satmosphere, climate, and geology.
The telescope's Wide Field and Planetary Camera 2 snapped imagesbetween April 27 and May 6, when Mars was 54 million miles (87 millionkilometers) from Earth. From this distance the telescope could seeMartian features as small as 12 miles (19 kilometers) wide.The telescope obtained four images (see PIA01587),which, together, show the entire planet.
This image is centered on the dark feature known as SyrtisMajor, first seen telescopically by the astronomer Christian Huygens inthe 17th century. Many small, dark, circular impact craters can be seenin this region, attesting to the Hubble telescope's ability to revealfine detail on the planet's surface. To the south of Syrtis is a largecircular feature called Hellas. Viking and more recently Mars GlobalSurveyor have revealed that Hellas is a large and deep impact crater.These Hubble telescope pictures show it to be filled with surface frostand water ice clouds. Along the right limb, late afternoon clouds haveformed around the volcano Elysium.

This image is centered near a volcanic region known asElysium. This area shows many small, dark markings that have beenobserved by the Hubble telescope and other spacecraft to change as aresult of the movement of sand and dust across the Martian surface. Inthe upper left of this image, at high northern latitudes, a largechevron-shaped area of water ice clouds mark a storm front. Along theright limb, a large cloud system has formed around the Olympus Monsvolcano.

This image is centered on the region of the planet known asTharsis, home of the largest volcanoes in the solar system. The bright,ring-like feature just to the left of center is the volcano OlympusMons, which is more than 340 miles (550 kilometers) across and 17 miles(27 kilometers) high. Thick deposits of fine-grained, windblown dustcover most of this hemisphere. The colors indicate that the dust isheavily oxidized ('rusted'), and millions (or perhaps billions) of yearsof dust storms have homogenized its composition. Prominent lateafternoon clouds along the right limb of the planet can be seen.

This image is centered near the location of the Pathfinder landing site. Dark sand dunes that surround the polar cap merge into alarge, dark region called Acidalia. This area, as shown by images fromthe Hubble telescope and other spacecraft, is composed of dark,sand-sized grains of pulverized volcanic rock. Below and to the left ofAcidalia are the massive Martian canyon systems of Valles Marineris,some of which form long linear markings that were once thought by someto be canals. Early morning clouds can be seen along the left limb ofthe planet, and a large cyclonic storm composed of water ice is churningnear the polar cap.
