OT....Hole in One...the Long Shot.... Into the Canyon? Mars Polar Lander May Have Crashed in Huge Hole on Red Planet With its solar arrays spread and the lander nestled inside, the probe was to delve into a neighboring world. For an idea of the craft's size, the heat shield at the bottom is 7.9 feet in diameter. (NASA) The Associated Press D E N V E R, Jan. 6 ? The vanished Mars Polar Lander probably broke apart in a canyon, The Denver Post reported today, citing scientists who suggested the landing site was the reason for NASA?s latest failure. The $165 million lander was supposed to touch down Dec. 3 for a 90-day mission to analyze the planet?s atmosphere and search for frozen water beneath its south pole. It has not been heard from since it started its descent after an 11-month cruise, and NASA has not offered a reason for the disappearance. Members of the Lockheed Martin team who maneuvered the craft to Mars believe a canyon nearly a mile deep and 6 miles wide in some places was the landing site, the Post reported, citing an unidentified source at the aeronautics company who was on the mission team. Orbiter Burned Up The source relied on ?probable? landing coordinates posted online by NASA and its Jet Propulsion Laboratory. Lab officials acknowledged that they knew the canyon was in the area. ?We believe we landed in a region that was in the vicinity (of the canyon), but we have no way of knowing whether it hit those slopes,? said Daniel McCleese, the Mars Surveyor Program scientist at JPL. The loss of the lander came less than three months after bungled communications between Lockheed and JPL caused the Mars Climate Orbiter to burn up in the Martian atmosphere. Who Knew? Lockheed scientists were reportedly surprised to learn that the canyon was inside the lander?s projected landing zone. During the mission, Lockheed scientists steered the craft under JPL direction. ?No one on our side knew that canyon was there,? the Lockheed source told the Post. ?All of the sudden, two weeks later, we got this MOLA data? ? topographical maps and images ? ?and it was like, ?Look at that hole!?? McCleese said mission scientists believed the south polar region offered ?some of the safest places on Mars.? However, he said, the planet is covered with craters and canyons and it is impossible to remotely place a spacecraft at a precise location. He also said JPL scientists couldn?t find a single landing zone on the planet?s generally smooth south pole without a hazard.
