The Engineering Breakthrough
Yvonne Brill's Electrothermal Hydrazine Thruster (1967):
Before Brill's patent (US Pat. 3,807,170), satellites required separate heavy propulsion systems for orbit insertion and delicate station-keeping. Brill invented an electrical heating element inside a single hydrazine decomposition chamber. By heating the decomposed gas, specific impulse (Isp) jumps from ~220s to over 300s, saving massive launch mass and keeping communication satellites pinpointed in orbit for decades.
