Video of Virgin Orbit NewtonFour Hot Fire

Video Caption: LauncherOne is powered by two rocket engines—a single NewtonThree on the main stage and a single NewtonFour on the upper stage. Both engines are turbopump-fed, gas generator cycle, LOX/RP-1 engines developed in-house here at Virgin Orbit. Here’s a typical test of the NewtonFour on our test stand up in Mojave, CA, in which the engine runs for a full six minutes—the same duration it would run during a full orbital launch. By popular demand, we’re posting this in real time–all six minutes of rockety goodness!
