Blue Origin's New Glenn heavy-lift launch vehicle is now ready for its first flight. The company has conducted — and successfully completed — a wet dress rehearsal or a full run-through of the rocket's launch countdown.

Blue Origin fired up its new heavy-lift orbital rocket for the first time just hours after receiving federal clearance to conduct its maiden launch.

The company, owned by the Amazon founder Jeff Bezos, also received approval from the Federal Aviation Administration to launch the vehicle to orbit.
