New Light Sail Design Would Use Laser Beam to Ride Into Space

Good News Notes:

“In long distance space travel, traditional rockets would eventually run out of fuel. There is an alternative: Since as early as the 19th century, scientists have dreamed of building spacecraft with light sails that can accelerate slowly, but for a much longer time, by catching the light from Earth’s sun or, in more modern designs, powerful ground-based lasers.

Researchers have now introduced a lab-tested design for a laser-driven light sail that can self-stabilize and could potentially ride a laser beam all the way out of our solar system.”
