Mars Patrol, Please Phone Home NASA Loses Contact With Mars Global Surveyor Orbiter By NED POTTER Nov. 13, 2006 — - Ten years ago -- 10 years last week, in fact -- a little ship named Mars Global Surveyor was launched from Florida, designed to spend two years in Martian orbit. It hasn't been heard from in a week now, and the engineers at the Jet Propulsion Lab in California are finally getting worried. Something on the ship apparently went awry when it sent a signal that it was having trouble orienting one of its solar panels to face...

Brown University Snow is the source of glacial deposits found at the base of the majestic volcanoes and mountains dotting the mid-latitude and tropical regions of Mars. Based on an innovative blend of geological observations and climate modeling created by a team of American and French scientists, the finding appears in Science. Discovery of the source of the tropical glaciers ends a 30-year Martian mystery. In 1976, cameras aboard NASA’s Viking Mission to Mars captured unprecedented views of the canyons and craters of the Red Planet – including polar ice caps. Recent spacecraft data reveal curious rock-strewn deposits found at...

Large outcrops of a gemstone mineral commonly used in jewellery have been found on the surface of Mars. On Earth, the mineral olivine takes the form of the brilliant green gemstone peridot. An instrument aboard a Nasa spacecraft spotted a 30,000 square kilometre area rich in olivine in the Nili Fossae region of Mars. The mineral, detected by the Mars Global Surveyor, was exposed on the surface. Scientists believe it might have been thrust up from below the ground by faults and fractures that cover the area. Olivine is abundant in the Earth's outer mantle, the layer just below the...

NASA Posts New Mars Images Fri April 4, 2003 11:01 PM ET WASHINGTON (Reuters) - Sand dunes that look like the scales of a giant fish and rare, wispy clouds are among more than 11,000 new images of Mars posted on the Internet, NASA said on Friday. The photographs, which scientists will examine to glean new clues about how much water there is on Mars and where, are posted atgallery msss. They were taken by the orbiting Mars Global Surveyor. "The new batch, taken between February and July 2002, brings the total number of images in the online gallery to...

Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2002 December 24 Spring Dust Storms at the North Pole of Mars Credit: MSSS, JPL, NASA Explanation: Spring reached the north pole of Mars in May, and brought with it the usual dust storms. As the north polar cap begins to thaw, a temperature difference occurs between the cold frost region and recently thawed surface, resulting in swirling winds between the adjacent regions. In the above image mosaic...
