New Glenn
New Glenn is a heavy-lift launch vehicle developed by Blue Origin. Named after the celebrated NASA astronaut John Glenn, the first American astronaut to orbit Earth, this launch vehicle represents a significant leap in Blue Origin's ambitions to make space more accessible.
Vehicle Specifications
New Glenn is designed to be a partially reusable heavy-lift launch vehicle. It is offered in both two-stage and three-stage variants, depending on the mission requirements. The vehicle is engineered to transport payloads to a variety of orbits, including geostationary transfer orbit (GTO) and low Earth orbit (LEO).
First Stage: BE-4 Engine
The first stage of the New Glenn is powered by seven BE-4 engines. These engines are revolutionary in their use of liquefied methane (LCH4) and liquid oxygen (LOX) as propellants, making them more environmentally friendly and cost-effective compared to traditional rocket fuels. The use of liquefied methane reduces the production of soot, which is a common byproduct in kerosene-based engines. Additionally, methane can be sourced more sustainably and has a higher efficiency in specific impulse.
Second Stage: BE-3U Engine
The second stage uses two BE-3U engines, which are variants of the BE-3PM engine used in the New Shepard suborbital vehicle. These engines are optimized for vacuum operations and utilize liquid hydrogen (LH2) and liquid oxygen (LOX) as propellants, achieving high efficiency and performance.
Payload Fairing
The payload fairing of New Glenn is among the largest in the industry, with a diameter of 7 meters. This allows the vehicle to carry more voluminous and sensitive payloads, including large satellites, space station modules, and interplanetary spacecraft.
Key Technologies
Reusability
One of the hallmark features of New Glenn is its reusability. The first stage is designed to be reusable for up to 25 missions, significantly reducing the cost per launch. After stage separation, the first stage returns to Earth, performing a controlled landing on a maritime platform.
Autonomous Landing and Recovery
The autonomous landing system in New Glenn utilizes a combination of GPS, inertial measurement units (IMUs), and onboard computers to execute a precise landing. This system ensures the safe recovery of the first stage for refurbishment and reuse.
Advanced Materials
The rocket's construction employs advanced materials like carbon composites and aluminum-lithium alloys. These materials offer a strong yet lightweight structure, enhancing the vehicle's performance and payload capacity.
Cryogenic Propellants
Utilizing cryogenic propellants such as liquid methane and liquid hydrogen plays a crucial role in the engine's efficiency. Cryogenic propellants must be stored at extremely low temperatures, thus requiring specialized storage and handling equipment.
Missions
New Glenn is intended for a wide array of missions, from commercial satellite launches to government and defense missions, and potentially even crewed missions. It aims to compete with other heavy-lift launch vehicles like SpaceX's Falcon Heavy and United Launch Alliance's Delta IV Heavy.
Astronaut John Glenn
The vehicle is aptly named after John Glenn, a pioneer in American space exploration. Glenn's historic flight on Mercury-Atlas 6 marked a significant milestone in the Space Race, inspiring generations of space enthusiasts and professionals.
