Airbus has launched a groundbreaking technology designed to mitigate the risks posed by tumbling satellites in space. The innovative device, named "Detumbler," was developed in association with Exotrail and EnduroSat and is scheduled for an in-orbit demonstration early in 2024. The Detumbler represents a significant advancement in addressing the challenges of space debris, particularly in Low Earth Orbit (LEO).

The Detumbler, a brainchild of Airbus and supported by the French Space Agency CNES under their Tech4SpaceCare initiative, was unveiled on Saturday, 11 November. This magnetic damping device, weighing approximately 100 grams, is engineered to be attached to satellites nearing the end of their operational lives. Its purpose is to prevent these satellites from tumbling, a common issue in orbital flight dynamics, especially in LEO. The device features a central rotor wheel and magnets that interact with the Earth's magnetic field, effectively damping unwanted motion.

Airbus' development of the Detumbler commenced in 2021. Its operational principle is simple yet innovative. When a satellite functions normally, the rotor behaves akin to a compass, aligning with the Earth's magnetic field. However, if the satellite begins to tumble, the movement of the rotor induces eddy currents, creating a friction torque that dampens this motion. The design of the Detumbler involves a stator housing, complete with a bottom plate and top cover, along with the rotor comprising the central axle, rotor wheel, and magnets.

Tumbling satellites, particularly those in LEO, pose a significant challenge for future active debris removal missions. Dead satellites naturally tend to tumble due to orbital flight dynamics. The introduction of the Airbus Detumbler could revolutionize this scenario, making satellites easier to capture during debris-clearing missions and enhancing the overall safety and sustainability of space operations.

The upcoming in-orbit demonstration of the Detumbler is a highly anticipated event. Scheduled for early 2024, it will be part of a mission from Exotrail, which will include the Exo-0 nanosatellite from EnduroSat. During this mission, dedicated detumbling tests will be conducted to verify the Detumbler's effectiveness in dampening satellite movement. This test is a pivotal step in ensuring the practical applicability of the Detumbler in real-world space conditions.

Airbus' Detumbler is not just a technological innovation; it's an encouraging sign that the aerospace industry's growing commitment to tackling the burgeoning issue of space debris is serious. As more satellites are launched into space, the need for sustainable and responsible space operations becomes increasingly critical. The Detumbler, by providing a feasible solution to the tumbling of end-of-life satellites, marks an important technical capability in this direction.
