Reliable rocket engine ignition involves precise orchestration of mechanical and fluid systems. Firefly engines go from idle to producing hundreds of thousands of horsepower in a fraction of a second. If anything is out of sequence, the results can be catastrophic. Firefly’s Lightning engine carries small canisters (one for each start) of igniter fluid called TEA-TEB which are used to ignite the liquid oxygen and RP-1 propellants in the thrust chamber.
