The first-stage rocket booster of the New Glenn launch vehicle is a crucial component that plays a significant role in the success of the mission. This booster, located at the base of the rocket, is equipped with seven powerful rocket engines that provide the necessary thrust for a successful takeoff.
One of the key features of the New Glenn booster is its ability to be guided back to Earth for a safe landing after launch. This innovative approach, pioneered by Blue Origin, aims to reduce costs by refurbishing and reusing the booster for future missions.
To ensure a safe landing, the New Glenn booster is equipped with several important elements. Four fins located at the top of the booster help steer the rocket during takeoff and landing. These fins, each roughly the size of a car, play a crucial role in guiding the booster back to Earth.
The structure of the booster is primarily made of aluminum, with a durable fabric thermal protection system known as 'Comet' developed by Blue Origin to protect it from reentry heating. The aerodynamic forces experienced by the fins during flight are comparable to the weight of a 737 aircraft, highlighting the challenges faced during the landing process.
In addition to the fins, the New Glenn booster features two strakes at its base, each similar in size to an F-16 wing. These strakes provide lift during the landing phase, supporting the booster as it descends back to Earth.
Overall, the design and capabilities of the New Glenn booster demonstrate Blue Origin's commitment to innovation and cost-effective space exploration. By focusing on reusability and advanced technology, Blue Origin is paving the way for a more sustainable and efficient approach to space travel.
