What it is

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.

Why Hacker News recommends it

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