Ancient Lake Delta Found On Mars

  The European Space Agency (ESA) said on Friday that it has discovered a crater on Mars that was once filled by a lake. NASA's Mars Global Surveyor spacecraft was first to identify the lake.  ESA said this delta structure is characteristic of the presence of a lake in the crater. The delta is an ancient fan-shaped deposit of dark sediments that is laid down in water, according to the space agency. The extinct lake is in the 40-mile-diameter Eberswalde crater that formed...

DENVER, Dec. 15, 2010 /PRNewswire/ -- A Lockheed Martin (NYSE: LMT)-built spacecraft, NASA's Mars Odyssey orbiter has worked longer at Mars than any other spacecraft in history. Odyssey entered orbit around Mars on Oct. 24, 2001 and today, the 3,340th day since that arrival, it passed the Martian career longevity record set by its predecessor, Mars Global Surveyor. Lockheed Martin also built and flew the Mars Global Surveyor for NASA's Jet Propulsion Laboratory (JPL). "Achieving this...

It was ten years ago that NASA announced the discovery of photographs revealing gullies on the surface of Mars, something that suggested water might still be flowing on the surface of the planet.   The breakthrough was followed by years of additional discoveries that pointed to the presence of water on the red planet. But a decade later, there is still no conclusive proof that such water exists.  However, the search for evidence, along with the many revelations that have...

LOS ANGELES -- NASA is investigating whether incorrect software commands may have doomed the Mars Global Surveyor spacecraft, which abruptly fell silent last year after a decade of meticulously mapping the Red Planet. The space agency said that theory is just one of several that may explain the probe's failure. NASA on Wednesday announced the formation of an internal review board to investigate why the Global Surveyor lost contact with controllers during a routine adjustment of its solar...

By ALICIA CHANG Associated Press Video: Possible Water Found on Mars LOS ANGELES -- New photographs from space suggest that water occasionally flows on the frigid surface of Mars, raising the tantalizing possibility that it is hospitable to life, scientists reported Wednesday. The new images, taken by NASA's Mars Global Surveyor before it lost contact with Earth, do not actually show flowing water. Rather, they show changes in craters that provide the strongest evidence yet that...

By JOHN JOHNSON JR. NASA scientists announced Wednesday that they had found evidence that water still flows over the surface of Mars - sporadic gushers that increase the possibility that the Red Planet could harbor some form of life. Using images obtained by the Mars Global Surveyor spacecraft, the researchers concluded that geologic changes in the shapes and sizes of gullies cut into the walls of two Martian craters were likely made by flowing water. The team looked at two sets of...

By Alicia Chang THE ASSOCIATED PRESS For decades, scientists have scoured Mars in search of water, a basic ingredient for primitive life. But the best clues were always tied to the ancient past when the Red Planet was warmer and wetter. On Wednesday, scientists made the startling announcement that water may still course through the frigid surface. Crisp photographs taken by NASA's old Mars Global Surveyor before it lost contact with Earth last month do not actually show flowing water....

The new images, taken by NASA's Mars Global Surveyor before it lost contact with Earth, do not actually show flowing water. Rather, they show changes in craters that provide the strongest evidence yet that water coursed through them as recently as several...

Pasadena, Calif. -- NASA's Mars Global Surveyor has likely finished its operating career. The spacecraft has served the longest and been the most productive of any mission ever sent to the red planet. "Mars Global Surveyor has surpassed all expectations," said Michael Meyer, NASA's lead scientist for Mars exploration at NASA Headquarters, Washington. "It has already been the most productive science mission to Mars, and it will yield more discoveries as the treasury of observations it has...

NASA's Mars robotic missions are performing so well, they are being prepared for additional overtime work. The team operating the twin Mars Exploration Rovers, Spirit and Opportunity, since January 2004, won approval for an additional year of exploration. NASA funded the extensions on recommendations from an outside panel of scientists. NASA also is adding two more years of operations for Mars Global Surveyor, which has been orbiting Mars since 1997, and the Mars Odyssey orbiter, at the red...
