Blue Origin is an American aerospace company founded quietly by Jeff Bezos in 2000, and funded for two decades largely out of his own fortune rather than external investment. It flies the suborbital New Shepard vehicle for space tourism and research payloads, and developed the heavy-lift New Glenn rocket alongside the BE-4 engine, which also powers United Launch Alliance's Vulcan. Headquartered in Kent, Washington, the company is building the Blue Moon lunar lander under a NASA Artemis contract and has moved from a deliberately slow development culture toward far more aggressive schedules under chief executive Dave Limp.
