NASA Rewires How It Models Rocket Shock

Kennedy Space Center engineers are applying finite element analysis in a new way — and already saving months of work per mission.

Engineers in the Dynamic Environments Group with NASA's Launch Services Program Office at the agency's Kennedy Space Center in Florida have developed a standardized finite element modeling workflow to predict how rockets and spacecraft behave under extreme conditions before hardware is built. [1]

[1] The new workflow replaces those older tools with a standard template that guides engineers through vibration profiles and shock conditions more quickly and thoroughly. [1]

The method was put to work during certification of a commercial launch provider's rocket selected for a NASA mission. [1]

The capability has already saved months by allowing the team to run analysis independently without having to request and wait for analysis reports or data, and by helping them identify risks that weren't previously considered. [1] Because most dynamic environments engineers use finite element tools infrequently, the standardized template also reduces the re-learning burden each time a new mission arrives. [1]

The shift reflects a broader tension in aerospace: the tools that matter most are often the ones that have existed longest, waiting for someone to apply them somewhere new.

NASA's Launch Services Program Office is responsible for launching rockets delivering spacecraft that observe the Earth, visit other planets and explore the universe, from weather satellites to space telescopes to Mars rovers. The team is constantly adopting new tools like this to give the agency the highest practical chance of success for each mission. [1]
