The Mars Climate Orbiter was lost at the Red Planet nearly seven weeks ago because the mission's navigation team was unfamiliar with the spacecraft. It lacked training, and failed to detect a mistake by outside engineers who delivered navigation information in English rather than metric units, according to a mission failure investigation report released Wednesday. A litany of errors and problems led to the loss of the $125 million spacecraft on Sept. 23, a loss that has complicated an upcoming Mars landing mission, the report says. The report was released Wednesday during a press conference at NASA Headquarters in Washington, D.C.
