Blue Origin nears testing of the BE-4 rocket

Blue Origin has its first BE-4 rocket engine fully assembled and ready for testing — and they pushed two more out the door recently.

Jeff Bezos’ Blue Origin space start-up aims to have a new rocket engine ready for installation aboard United Launch Alliance’s new Vulcan rocket by 2019.

Blue Origin has signed its first customer for a commercial satellite launch. European satcom Eutelsat aims to become Blue Origin’s inaugural customer five years from now, utilizing a Blue Origin New Glenn large rocket to launch one of its comm-sats into high geostationary orbit. Then, just a day later, Blue Origin announced its second customer, OneWeb — soon to be merged into Intelsat.

The New Glenn will use seven BE-4 engines.

Each BE-4 will have 550,000 pounds of thrust.
