New Glenn

New Glenn, named after John Glenn, is a heavy-lift orbital launch vehicle in development by Blue Origin. Design work on the vehicle began in 2012. Illustrations of the vehicle, and the high-level specifications, were initially publicly unveiled in September 2016. New Glenn is described as a two-stage rocket with a diameter of 7 meters (23 ft). Its first stage will be powered by seven BE-4 engines that are also being designed and manufactured by Blue Origin.

Like the New Shepard suborbital launch vehicle that preceded it, the New Glenn’s first stage is designed to be reusable. Originally intended for first launch in 2020, by 2018 Blue Origin expected to launch New Glenn in 2021, which remains the current target.

Blue Origin will offer both single-payload dedicated flights and, after the fifth launch, dual-manifesting of large commsats to be transported to geostationary transfer orbit. All contracted launches from the start will feature a reusable first-stage, so just like the practice in commercial aircraft transport, landing conditions can affect the timing and flight parameters of a launch.

Blue intends to contract for launch services a bit differently than contract options that have been traditionally offered in the commercial launch market. The company has stated they will contract to aim to have a regular launch cadence of up to eight times a year. If one of the payload providers for a multi-payload launch is not ready on time, Blue will hold to the launch timeframe, and fly the remaining payloads on time at no increase in price.
