A Rocket for a NASA Mission Got Vibration Testing but Not Shock Testing. Then the Dynamic Environments Group Ran the What-Ifs.
Engineers in the Dynamic Environments Group at NASA's Launch Services Program Office at the agency's Kennedy Space Center have streamlined how they ensure spacecraft and rockets can withstand harsh vibration, shock, stress and other physical forces. The software's first outing came while certifying a commercial launch provider's rocket selected for a NASA mission — a partner that supplied vibration testing but not shock testing.
The group determined shock testing was needed, then used a template it had created to run what-if comparisons, visualise structural behaviour and answer questions that would once have required extensive manual modelling.

The quiet benefit here is a workflow nobody has to relearn. Most dynamic environments engineers reach for finite element modelling tools only occasionally and end up re-learning complex steps; a standard template that replaces older tools walks them through vibration profiles and shock conditions faster and more thoroughly.
Credit the judgement rather than the software. The partner's testing covered vibration and stopped there; someone still had to decide shock testing was needed, and that call came from the group. The template only did the what-if comparisons afterwards.
That call matters because of when it happens. Problems found on the ground can still be addressed, but once a rocket leaves the launch pad most cannot be repaired or corrected — which is what makes early identification essential.
