More evidence found suggesting water on Mars
NASA/JPL/MSSS PHOTO RELEASE
Posted: November 20, 2000
NASA's Mars Global Surveyor spacecraft, currently orbiting Mars, simultaneously snapped both a wide-angle and high-resolution view of Hale crater that show gullies -- possibly carved by water -- in the peaks of sand dunes inside the crater.
The two pictures on this page were taken simultaneously by the Mars Global Surveyor Mars Orbiter Camera on November 10, 2000. The sun illuminates the scene from the northwest (upper left) about 22 deg above the horizon. Knowing the sun angle and the length of the longest shadow (~1.6 km; ~1.0 mi), the height of the largest peak in the high resolution view (below) is about 630 meters (~2,070 ft) above the crater floor.
The high resolution view covers an area 3 km (1.9 mi) wide at a full-resolution scale of 3 meters (9.8 ft) per pixel. Winter in the southern hemisphere will begin in mid-December 2000.
Mars Global Surveyor is managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, Washington, D.C. JPL is a division of the California Institute of Technology, Pasadena.
Malin Space Science Systems and the California Institute of Technology built the Mars Orbiter Camera using spare hardware from the Mars Observer mission. MSSS operates the camera from its facilities in San Diego, CA. The Jet Propulsion Laboratory's Mars Surveyor Operations Project operates the Mars Global Surveyor spacecraft with its industrial partner, Lockheed Martin Astronautics, from facilities in Pasadena, CA and Denver, CO.
