Researchers at Texas A&M University have developed micron-scale devices called metajets, which can be propelled and steered in three dimensions using laser beams, a significant advancement in light propulsion technology. These metajets, designed with intricate patterns that act like lenses, allow for precise control of momentum transfer from photons, enabling steering beyond simple push. Published in Newton, this innovation builds upon the concept of solar sails but utilizes lasers for greater control and potential scalability. The team believes this propellant-free method could one day enable ambitious deep space missions, such as a 20-year journey to Alpha Centauri, and plans to test the metajets in a microgravity environment.
