Mars Climate Orbiter
The Mars Climate Orbiter (formerly the Mars Surveyor '98 Orbiter ) was a 338-kilogram (745 lb ) robotic space probe launched by NASA on December 11, 1998 to study the Martian climate , Martian atmosphere , and surface changes and to act as the communications relay in the Mars Surveyor '98 program for Mars Polar Lander . However, on September 23, 1999, communication with the spacecraft was lost as the spacecraft went into orbital insertion , due to ground-based computer software which produced output in non-SI units of pound-force seconds ( lbf ·s) instead of the SI units of newton-seconds (N·s) specified in the contract between NASA and Lockheed . The spacecraft encountered Mars on a trajectory that brought it too close to the planet, causing it to pass through the upper atmosphere and disintegrate. [1] [2]
