Texas A&M scientists developed micron-scale 'metajets' that move in all three dimensions when illuminated by lasers, a world’s first, as published in Newton journal.
The team claims their approach could eventually propel spacecraft to Alpha Centauri in about 20 years, vastly reducing current travel times by leveraging scalable laser power.
While prior solar sail experiments used sunlight for propulsion, this research advances the concept with precise laser control, though further testing in microgravity is needed to prove feasibility for space missions.
Can microscopic 'metajets' truly be scaled up to power a full-sized interstellar light sail?
How soon could this laser sail technology actually launch a probe to another star system?
With NASA pursuing nuclear power, is laser propulsion our best bet for reaching the stars?
Beyond starships, how can this laser tech manipulate cells for medical breakthroughs?
Graphene or silicon: which material will win the race to build a practical laser sail?
How will a starship traveling at 20% light speed brake upon reaching Alpha Centauri?
Laser-Powered Metajets: The Future of Scalable, Fuel-Free Space Propulsion
Overview
In April 2026, researchers at Texas A&M University led by Dr. Shoufeng Lan demonstrated full 3D control of microscopic metajets using laser light, eliminating the need for onboard fuel. These metajets, built from nanoscale-engineered metasurfaces with embedded directional control, convert photon momentum into precise mechanical forces, enabling scalable propulsion based on laser power rather than device size. While initial tests in fluid environments proved the concept, the team plans microgravity testing to validate space applications. Despite challenges like laser delivery over vast distances and manufacturing precision, laser propulsion stands out as the most viable near-term method for rapid interstellar travel, with future goals including orbital uses and interstellar probes accelerated by large laser arrays.
