From Micro to Interstellar: The Future of Optical Propulsion

Researchers at Texas A&M University have created micron-scale “metajets” that use laser light for precise, contactless 3D movement. Built from engineered metasurfaces, these devices convert light into controlled force—enabling propulsion and levitation without traditional mechanics.Unlike conventional systems, maneuverability is embedded directly into the material, not the light source. This scalable approach to optical propulsion could extend far beyond the lab, potentially powering future spacecraft.If paired with high-energy lasers, the concept could one day enable faster journeys to distant targets like Alpha Centauri—bringing long-range space travel closer to reality.Thank you for listening to Bedtime Astronomy — your guide to the cosmos.
