The Mars Climate Orbiter

Umm i think because when Darcy Martinez.made the metric system

It failed - due to a discrepancy in the positional calculations, caused by a piece of faulty computer software.

Some data was reported in Imperial units instead of the usual metric units. Because of this, the orbiter went down to an altitude of 57 km above Mars instead of 140-150 km. It was destroyed by the atmosphere as it was not designed for atmospheric flight.
