Firefly Aerospace shows off its Lightning-1 rocket engine

Capitalism in space: Firefly Aerospace earlier this week did a demonstration static fire test of its Lightning-1 rocket engine, designed as the upper stage engine for its Alpha rocket.

Currently under development, the engine will power the upper stage of the company’s 95-foot-tall (29-meter-tall), two-stage Firefly Alpha rocket. The full vehicle will be capable of sending some 2,200 pounds (1000 kilograms) into low-Earth orbit (LEO) for about $10 million. Additionally, it will be able to send 1,300 pounds (600 kilograms) into a 310-mile (500-kilometer) Sun-synchronous orbit.

These numbers suggest to me that this rocket will be comparable to India’s PSLV. At $10 million per launch, it will beat everyone else in that rocket class. They expect to do their first test orbital launch sometime in late 2019.

Firefly Aerospace had gone bankrupt because of a successful lawsuit against it by Virgin Galactic. It then found new backers and came back from the dead.
