NASA Lost a $125M Spacecraft Over Pounds vs Newtons

In 1999, NASA's Mars Climate Orbiter flew for more than nine months to reach Mars, then vanished. The cause: one ground software file gave thruster data in pound-force seconds, while the navigation team expected metric newton-seconds.

Here's the full story from NASA's own investigation report, explained simply, with lessons for anyone whose systems pass data between teams or tools.

TODAY'S LESSON: The most expensive bugs live between two teams. 1. Write down every detail both sides depend on: units, formats, time zones. 2. Test the handover, not just each part. 3. When numbers look slightly off, find out why.

Dramatised true story. Characters are stand-ins and the spacecraft is an illustration. Facts are from NASA's Mars Climate Orbiter Mishap Investigation Board Phase I report (Nov 10, 1999). The ~$125M orbiter cost is as widely reported. llis.nasa.gov/llis_lib/pdf/1009464main1_0641-mr.pdf science.nasa.gov/mission/mars-climate-orbiter/
