Engineers from the Swiss Federal Laboratories for Materials Science and Technology (Empa) and the aerospace firm Beyond Gravity have developed a new satellite adapter. The device utilizes phononic crystals to mitigate vibrations during rocket launches, replacing traditional rubber shock absorbers.
The adapter functions by converting longitudinal vibrations, which can damage sensitive satellite components like optics and electronics, into rotational motion. This is achieved through a system of movable aluminum rings that dissipate kinetic energy, significantly reducing the load reaching the satellite.
This technology could allow for lighter satellite designs with reduced safety margins, potentially lowering launch costs or enabling more scientific equipment to be carried. It is considered particularly promising for missions involving high-precision optical instruments and quantum sensors.
The project is currently at a technology readiness level of 4–5. Beyond Gravity has filed a patent application for the design, which has already undergone computer modeling and laboratory testing. Further trials in realistic conditions and certification are required before deployment.
