Texas A&M researchers demonstrated laser-driven metajets—ultrathin, patterned devices—that can be steered in three dimensions by transferring photon momentum, with potential to scale to larger craft and, given enough laser power, enable a ~20-year voyage to Alpha Centauri; experiments were conducted in a fluid environment to observe controllable motion and microgravity tests are planned for space readiness.
Texas A&M researchers report a lab demonstration of micron-scale metajets with metasurfaces that can be steered in three dimensions by laser light; they say the concept could be scaled to propel larger spacecraft, potentially enabling a 20-year journey to Alpha Centauri, though real-world feasibility and space testing remain to be proven.
Texas A&M researchers demonstrated micron-scale metajets that use metasurfaces to move in three dimensions when illuminated by laser light, enabling 3D maneuverability that could, in theory, scale to propel larger craft. While the approach could cut a trip to Alpha Centauri to about 20 years, feasibility remains uncertain as tests to date occurred in fluid environments and microgravity space tests are planned to validate practicality and scaling.
Texas A&M researchers demonstrated micron-scale metajets—metasurface-based devices that transfer momentum from light to lift and steer objects in 3D without contact—marking a scalable path for light-propulsion and potential interstellar missions to Alpha Centauri, contingent on sufficient optical power and funding; space-testing is the next step after fluid experiments that offset gravity.
