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.

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’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.
