Education Frontlines: More reasons to go metric

Over twenty-five years ago, our failure to adopt the metric system resulted in the loss of our Mars Climate Orbiter probe launched at Cape Canaveral on December 11, 1998. On September 23, 1999, communication with the orbiter was lost as it came too close to the surface of Mars. An investigation discovered the failure to be caused by a mismatch between the metric units used by NASA and the spacecraft’s builder Lockheed Martin that used the non-metric system.
