Anticipating Blue Origin's New Glenn Rocket Launch: A Detailed Overview
0:00:06 Introduction: Scott Manley highlights the imminent first orbital launch attempt of Blue Origin's New Glenn rocket after 25 years of development.
0:00:41 New Glenn's Scale: New Glenn, a large orbital rocket, was announced in 2016, and is comparable in size to Falcon Heavy, but with more modern features like higher efficiency engines and reusability. It stands 98 meters tall with a 7-meter wide core.
0:01:41 Rocket Design: The two-stage rocket features a methane and liquid oxygen-burning first stage and a hydrogen-burning second stage for enhanced orbital performance.
0:01:54 First Stage: The reusable first stage is 58 meters tall and divided into three sections: an aft section with seven BE-4 engines, a main tank section, and a forward section with control thrusters and fins.
0:02:41 BE-4 Engines: The first stage's seven BE-4 engines use an oxygen-rich staged combustion cycle with methane and liquid oxygen, each producing about 250 tons of thrust. The engines are designed for lower chamber pressure to extend their lifespan.
0:04:16 Second Stage: The 7-meter wide second stage uses hydrogen and oxygen, propelled by two BE-3U engines, which are vacuum versions of the New Shepard engines using an expander cycle for increased thrust.
0:05:55 Performance: The upper stage is expected to deliver 45 tons to low Earth orbit and 13 tons to geostationary transfer orbit.
0:06:23 Payload Fairings: New Glenn boasts the largest fairings in the business at 7 meters wide and 17 meters tall, providing ample space for large payloads.
0:06:59 First Payload: The debut launch will carry "Blue Ring," a test satellite bus with its own propulsion and power capabilities.
0:07:33 Reusability: New Glenn's first stage is designed for reusability, with a planned 3-minute and 10-second burn, followed by a staging operation and an atmospheric entry burn before landing on the barge "Jacqueline."
0:08:18 Heat Shield: The first stage features a gold-colored heat shield material called "Comet," designed for atmospheric heating during descent.
0:09:36 Hover Capability: New Glenn may have the ability to throttle down for hovering, enabling more precise landings.
0:10:25 Landing Barge Operations: A drone will connect to the landed booster on the barge for safe defueling.
0:10:51 Landing Legs: The six landing legs are designed to integrate seamlessly into the aft section and can each handle 150 tons of impact force.
0:11:07 Estimated Mass: The estimated launch mass of New Glenn is around 1,200 to 1,300 tons.
0:11:57 Development Philosophies: Blue Origin's methodical testing approach contrasts with SpaceX's iterative design philosophy.
0:13:17 Mission Differences: New Glenn is designed for missions to geostationary orbit, the Moon, and Mars, while Starship currently requires multiple refuelings for such missions.
0:15:09 Future Developments: A three-stage version of New Glenn and a reusable upper stage (Project Jarvis) have been considered, potentially offering capabilities similar to Starship.
0:16:09 Customers: Blue Origin has secured customers for New Glenn, including Amazon for their Kuiper satellite constellation, OneWeb, and NASA.
