Blue Origin’s New Glenn rocket hit a significant milestone this week, completing its first second-stage hot fire test that validates the interactions between the subsystems, its two BE-3U engines, and the ground control systems.

The static test fire at Space Launch Complex 36 at Cape Canaveral SFS marked Blue Origin’s first fueling of a New Glenn rocket stage with flight propellants, and the first engine burn of an integrated flight stage.

This marked the first time that Blue Origin, a space company founded by Jeff Bezos more than two decades ago, has integrated and fired an orbital rocket stage. After the test, Blue Origin said it is still tracking toward a November launch of the New Glenn rocket.

Blue Origin carried out a hotfire test for its New Glenn rocket second stage on Monday (Sept. 23) as the company moves toward the huge vehicle's debut flight.
