What's a light sail?
In 2019, the Planetary Society, a U.S.-based space education and outreach nonprofit, launched a crowdfunded light-sail-powered spacecraft calledto Earth orbit. The cubesat spacecraft is just about the size of a loaf of bread, but its solar sail stretches over about 433 square feet . The first paper, led by Igor Bargatin, a researcher in the department of mechanical engineering and applied mechanics at the University of Pennsylvania, proposes the best material and shape for an interstellar light sail.
"The intuition here is that a very tight sail, whether it’s on a sailboat or in space, is much more prone to tears," Bargatin said in the same statement."It’s a relatively easy concept to grasp, but we needed to do some very complex math to actually show how these materials would behave at this scale."
