Which has sort-of happened already in history of space exploration, when Mars Climate Orbiter mis-handled Mars orbitial insertion and was lost. The problem was traced down to mis-match of measurement units used in software (Newtons vs. Pound-force).

- drzaiusapelord 14y agoYep happened once in 50 years of space travel. Ugh, we get it, everyone thinks they're being cute and its a way to mock US units. Yes, yes, this isn't getting incredibly tiresome.

- wallflower 14y agoThe most famous smallest but most significant human error was Mariner I: "The error had occurred when a symbol was being transcribed by hand in the specification for the guidance program. The writer missed the superscript bar (or overline) in [the formula] by which was meant "the nth smoothed value of the time derivative of a radius R". Without the smoothing function indicated by the bar, the program treated normal minor variations of velocity as if they were serious, causing spurious corrections that sent the rocket off course. It was then destroyed by the Range Safety Officer." http://en.wikipedia.org/wiki/Mariner_1 http://en.wikipedia.org/wiki/Mariner_1
- drivebyacct2 14y agoAs an American, I would prefer that the stubbornness continue to be mocked in a hope that someday we might get rid of this silly system.
- jimktrains2 14y agoIIRC, it was an accumulation of errors when converting between units, not a unit mis-match.
- wr1472 14y agoRoot cause is still a unit mis-match though.
- InclinedPlane 14y agoNot exactly, ultimately it was just that. The problem was that there was a spec for a file format for data from the spacecraft that was supposed to be in metric units, but some of the data was in imperial units, against the spec. This resulted in a course deviation which ultimately doomed the spacecraft. That said, there were warning signs that something was wrong which the ops team didn't pick up on but should have.
