How did they get to know what had happened? Was it reconstructed after the crash? If so, then why was it not simulated beforehand? Or did they get live data during it?
- reidjs 8y agoSurely there was an equivalent of a black box on the spacecraft right? Just a hunch I don’t actually know
- jffry 8y ago"The SRI internal events that led to the failure have been reproduced by simulation calculations. Furthermore, both SRIs were recovered during the Board's investigation and the failure context was precisely determined from memory readouts. In addition, the Board has examined the software code which was shown to be consistent with the failure scenario. The results of these examinations are documented in the Technical Report." You may also be interested in section 2.3 which describes the factors that led to simulations failing to discover this failure mode [1] https://web.archive.org/web/19970125194224/http://www.esrin.esa.it:80/htdocs/tidc/Press/Press96/ariane5rep.html https://web.archive.org/web/19970125194224/http://www.esrin....
