Swiss Engineers Just Designed a Better 'Shock Absorber' for Spacecraft

Swiss engineers have developed a new type of payload adapter for spacecraft that reduces the impact of vibrations during rocket launches. The adapter uses phononic crystals, a type of metamaterial that can control and redirect mechanical waves. This technology helps prevent damage to satellites by transferring the energy of vibrations into rotational motion, thus reducing the stress on the satellite's internal systems. The adapter is lighter and more efficient than traditional mechanical systems, which can add weight to rockets and increase launch costs.

• The adapter has passed computer simulation and lab bench stress tests.
• It is currently at a Technology Readiness Level (TRL) 4-5, which means it is in the development phase.
• The technology could allow for more payload capacity or lighter satellites, potentially lowering launch costs.
• It could enable the use of more fragile instruments, such as thin optics or sensitive sensors, that would otherwise be damaged by vibrations.
