Planned high-resolution photos of the site should help mission scientists refine their theory of why the lander failed. (You can unsubscribe anytime). They were suppose to continue firing until one of the craft's landing legs touched the surface. In December 1999 NASA's Mars Polar Lander (MPL) was supposed to touch down near the red planet's south pole. Mars Polar Lander crash site spotted Posted: Fri, May 6, 2005, 8:20 AM ET (1220 GMT) Scientists examining images of the surface of Mars said Thursday that they have spotted what they believe may be the crash site of NASA's Mars Polar Lander spacecraft. Almost immediately, scientists began looking for the missing lander with the Mars Orbiter Camera (MOC) aboard NASA's Mars Global Surveyor. October 24, 2005 All rights Reserved. The Mars Polar Lander's December 1999 demise apparently occurred when the lander thought the jolt of its landing leg deployment was touchdown - and shut its engines off. September 11, 2003. © 2020 American Association for the Advancement of Science. Later this year NASA will direct Mars Global Surveyor to reexamine the MPL crash site using a special technique to improve the camera's resolution to 0.5 meter per pixel. Shortly thereafter, a review board looking into the craft's disappearance reported what might have caused Mars Polar Lander's demise. The parachute-like feature closely matched the Mars Exploration Rover parachutes (which were made of the same materials), and Malin believed the disturbed ground matched what one would see if a rocket had blasted the surface from a height of tens of meters — the final phase in the MPL touchdown maneuver. Using information gained from observing the two Mars Exploration Rover landers last year, Malin reexamined the 1999 and 2000 images looking for similar features. July 17, 2008, By: Camille M. Carlisle But shortly after it entered the Martian atmosphere, the spacecraft disappeared without a trace. MARS POLAR LANDER, DEEPSPACE2 SETFORARRIVAL NASAreturns to the surface of Mars on December 3 with a spacecraft that will land on the frigid, windswept steppe near the edge of Mars’ south polar cap. So MOC reexamined the scene on September 27th under nearly identical lighting conditions. This time he identified what looks to be a parachute located several hundred meters away from a disturbed bit of ground with a large mark in its center. The transmission never came. By: David Tytell If confirmed, the images would rule out an alternative scenario that the lander tumbled down a steep slope, Zurek says.

"Our confidence that this is the prime candidate [for the crash site] has increased quite a bit," says Richard Zurek of NASA's Jet Propulsion Laboratory in Pasadena, California, the lander's project scientist. In the center of the disturbed ground was a notable mark — presumably the missing lander. More observations were needed to conclusively identify the missing lander. Piggybacking on the lander are two small probes that will smash into the Martian surface to test new technologies. It was scheduled to send a signal to Earth after touchdown, telling about its descent. The $165 million Mars Polar Lander crashed near the Martian south pole less than 3 months after a sister mission, Mars Climate Orbiter, burned up while entering the planet's atmosphere at the wrong altitude. Only now, 5½ years later, do scientists think they may have finally located the lander's wreckage and confirmed what went wrong with the mission. Shortly after NASA's Mars Polar Lander (MPL) entered the Martian atmosphere on December 3, 1999, the spacecraft disappeared without a trace. Copyright ©2020 AAS Sky Publishing LLC. By: Camille M. Carlisle The board suggested that MPL's landing rockets fired at the right time and altitude but cut off prematurely. It was only a few short moments before touchdown that disaster struck.". Malin hopes the new observations will provide the conclusive evidence needed to officially close the case of the missing Mars Polar Lander. By: Monica Young The search for Mars Polar Lander was hampered by inexperience: the team didn’t know what a parachute should look like or how the ground would be disturbed by the landing rockets. Mars Polar Lander disappeared without a trace on December 3, 1999. NASA investigators concluded that the descent rockets on Mars Polar Lander turned off too quickly, dooming the craft to a 40-meter freefall. Malin plans to take sharper photos later this year, using a new technique that adjusts for the satellite's fast motion in orbit.

An image of the Martian surface shows the likely sites of a parachute deployed by the failed Mars Polar Lander and a patch of dust scoured away by its rocket thrusters. All rights reserved. Malin used his company's Mars Orbiter Camera (MOC) aboard NASA's Mars Global Surveyor to search for the missing spacecraft in late 1999 and early 2000, but apparently came up empty. April 13, 2004. In a new analysis of 5-year-old images, researchers believe they see a discarded parachute and an imprint from the rocket engines of Mars Polar Lander, which crashed in December 1999.

Malin says that MOC will no longer look for MPL. Above: Comparison of the Mars Polar Lander (MPL) landing site region with California.The left half of the figure shows a map of Mars' south polar region created from Viking images. When those rovers landed last year, they also used parachutes and rocket-engine blasts to slow their descents. The images contained a half-dozen candidate spots, but no one could firmly identify the debris. September 15, 2004, By: Kelly Beatty An image of the Martian surface shows the likely sites of a parachute deployed by the failed Mars Polar Lander and a patch of dust scoured away by its rocket thrusters.

Using those hints, Malin re-examined his old images of the Mars Polar Lander crash region. Courtesy NASA/JPL/Malin Space Science Systems. The parachute-like feature closely matches the Mars Exploration Rover parachutes (which were made of the same materials), and Malin believes the disturbed ground matches what one would see if a rocket had blasted the surface from a height of tens of meters. Any future searches will be conducted by the Mars Reconnaissance Orbiter's HiRISE instrument, which can return images of the surface as detailed as 1 meter per pixel after it arrives at the Red Planet in March 2006. Orbiter photos clearly show the ditched parachutes and patches where the rockets blew away dust, says planetary scientist Michael Malin of Malin Space Science Systems in San Diego, California, who built the orbiter's camera.

A satellite orbiting Mars may have found debris from one of the worst accidents in NASA's planetary program. No one has seen any evidence of the ill-fated craft — until now.

Sky & Telescope is part of AAS Sky Publishing, LLC, a wholly owned subsidiary of the American Astronomical Society. Apparently the onboard software mistook the jolt of landing-leg deployment for ground contact and shut down the engines, causing MPL to fall from a presumed height of 40 meters (130 feet). This time he identified what looks to be a parachute located several hundred meters away from a disturbed bit of ground with a large mark in its center.

February 26, 2016, By: Jay Anderson The failed Mars Polar Lander spacecraft, once thought found, remains missing after the proposed 'crash site' was reinvestigated in September. Related sitesMore images and background from Malin Space Science SystemsSky & Telescope reportMars Polar Lander, By Lindzi Wessel, Rodrigo Pérez Ortega Oct. 21, 2020. Malin reports his new analysis in the July issue of Sky & Telescope. The failed Mars Polar Lander spacecraft, once thought found, remains missing after the proposed 'crash site' was reinvestigated in September. May 31, 2017, By: Stephen James O'Meara A tiny fleck within that zone may even show the small lander itself. "MPL’s descent proceeded more or less successfully through atmospheric entry and parachute jettison. A white spot of the right brightness and shape looks like the parachute, while a dark patch scoured into the planet's fine dust looks like the rocket blast zone nearly 500 meters away. "Brightest Supernova Ever" or Shredded Star. MPL's landing site is drawn as a 240 km by 20 km ellipse to reflect the accuracy at which the spacecraft can be targetted. Malin and his team conclude that the mark they saw in the older image was noise in the data. Detective work. All rights reserved. Investigators concluded that MPL’s landing rockets cut off prematurely and that the craft fell several dozen meters to its death. The full report, by planetary scientist Michael C. Malin (Malin Space Science Systems), appears in the July 2005 issue of Sky & Telescope, now in press.
