Researchers at Texas A&M University have demonstrated optical propulsion using laser-driven “metajets” with full three-dimensional control.
Their lab-scale results suggest that light-powered propulsion systems could cut travel time to Alpha Centauri, the closest star system to ours, to roughly 20 years.
Current space propulsion technologies would take hundreds of thousands of years to complete this journey, highlighting the immense potential of optical propulsion in driving future endeavours into the final frontier.
What is optical propulsion, and why is it gaining traction?
Optical propulsion uses light, typically from lasers, to generate force on objects without physical contact or onboard fuel. While the physics has been understood for decades, practical control has remained a barrier.
