There has been several references that SpaceX "fly" their Falcon 9 computer systems to test for bugs like this. The idea being that as far as the computer is concerned, it is a real flight and should act accordingly. Most of the problems to date, have been related to a mechanical problem. During the first docking, there was a minor issue with the sensor "field of vision" but this was fixed.
The point is that SpaceX procedures seem to be able to prevent similar software bugs in the Ariane 5 from causing a catastrophic abort or failure.
- kiba 14y agoHow come the flight system at Ariane 5 wasn't tested like this?
- InclinedPlane 14y agoResources? Afterward they simulated flights using the Ariane 5 systems and duplicated the errors.
- kiba 14y agoI don't think resource is an issue given that they spend a lot of money on its development.
- InclinedPlane 14y agoMost big bureaucratic organizations tend to be "penny wise and pound foolish". They might spend billions on developing a new launch vehicle but balk at spending a few million on a HIL simulation of a real launch.

- axusgrad 14y agoThey have to fool the sensor inputs to look like a real flight, right? They can't necessarily think of every realistic but unexpected input. Definitely worth trying, though. I'd actually be surprised if they hadn't done that with the Ariane.
