NASA Spacecraft Separation Modeling: Simulink vs. Julia

Cited again and again as the concrete case study behind the claim that NASA got a 15,000x speedup moving from Simulink to Julia.

A JuliaCon talk by a NASA Launch Services Program engineer on modeling spacecraft separation dynamics in Julia. He describes replacing a Simulink-based workflow for checking launch vehicle separation requirements with Julia and ModelingToolkit, with large speedups and much shorter code.
