United Launch Alliance’s next-generation Vulcan rocket – and Blue Origin’s next-generation BE-4 rocket engine – have been chosen to send Astrobotic’s Peregrine moon lander as well as Sierra Nevada Corp.’s Dream Chaser mini-shuttle to the final frontier in 2021.
Neither of the past week’s announcements is all that surprising, because Astrobotic and SNC both had previous agreements to use ULA’s current-generation Atlas 5 rocket. But both announcements underscore the importance of holding to the current schedule for rolling out the BE-4 as well as the Vulcan, which is designed to use two BE-4 engines on its first-stage booster.
Blue Origin, the privately held space venture founded by Amazon CEO Jeff Bezos, is thought to be in the final stages of testing the BE-4’s performance – not only for ULA’s Vulcan but also for its own orbital-class New Glenn rocket, which is also due for its maiden flight in 2021.
