You might be referring to the Mars Climate Orbiter mishap. It crashed into the atmosphere because NASA used SI units, while Lockheed Martin, who worked as a contractor, used imperial. Specifically, what fucked it up was the measurement of impulse of the thrusters (pound-force-seconds vs newton-seconds)
Isn’t this why they wrote off two Mars missions?
