Before it begins its work as a weather satellite, the orbiter will act as a radio relay for Mars Polar Lander. The miscalculations put the spacecraft off course by only about 60 miles out of a journey of roughly 416 million miles, Dr. Stone said. observing how moisture evaporates from the ground and migrates through the air for an entire Martian year -- 687 Earth days. are all about.". But scientists at the Jet Propulsion Laboratory assumed the figure was in newtons and incorporated it into computer models that are used to calculate the spacecraft's position and direction. Mars Climate Orbiter A NASA mission launched Dec. 1998 to produce information about the surface and climate of Mars. Mars Climate Orbiter war zusammen mit Mars Global Surveyor dafür gebaut worden, die Instrumente des verlorenen Mars Observer doch noch zum Einsatz bringen zu können. The Mars Climate Orbiter, the first spacecraft specifically designed to study the climate of another planet, was inexpensive by NASA's standards. The Mars Climate Orbiter, the first spacecraft specifically designed to study the climate of another planet, was inexpensive by NASA's standards. ''There is not a single mission in the program that is critical to the overall program,'' said Dr. Stone, the Jet Propulsion Laboratory director. The spacecraft, called Mars Climate Orbiter, is programmed to make the first full-scale study of Martian weather. Services | Books | Home | Editorial | ''The real issue is that our process did not realize there was this discrepancy and correct for it. New York Today, Copyright 1998 The New York Times Company. Diversions | Since one pound equals about 4.4 newtons, it would seem that such an error would be readily detected, but Dr. Hinners said this was not the case because the thrusters contributed only a little to the trajectory. Mars Climate Orbiter and its sister mission, the Mars Polar Lander, are part of a series of missions in a long-term program of Mars exploration managed by the Jet Propulsion Laboratory for NASA's Office of Space Science, Washington, DC. The House recently moved to strip $1.8 billion from Lockheed Martin's F-22 fighter jet program, citing technical difficulties with the program. Orbiter is on its way to the red planet.". The orbiter is the third in a series of nine probes to be launched by the National Aeronautics and Space Administration through 2005, with the goal of returning a sample of Martian soil to Earth. National/N.Y. These failures led the company to restructure its operations and change management in its space business. This was measured in pounds, Dr. Hinners said. and Mars Pathfinder, which carried a rock-exploring rover, arrived on Mars last year. Job Market | The resulting miscalculation, undetected for months as the craft, the Mars Climate Orbiter, was designed, built and launched, meant it was off course by about 60 miles as it approached Mars. But the review team now tends to think that the spacecraft might have left Mars's orbit and is now orbiting the sun.. The question that will have to be asked here is whether in cutting costs, they cut corners.''. Forums | From the start NASA suspected human or software error, rather than mechanical failure. Together, Mars Climate Orbiter and Mars Polar Lander will look for water in the Martian soil and atmosphere. | An independent NASA failure review board will be formed shortly. That limits the damage done by the failure of any single mission. ''The real issue is not that the data was wrong,'' said Edward C. Stone, the director of the Jet Propulsion Laboratory, in Pasadena, Calif., which was in charge of the mission.
