Spacecraft could fly to distant stars using sails with surfaces similar to those of CDs and DVDs to help them stay centered on laser beams, a new study finds. One concern with using laser sails is that if they drift out of alignment with the propelling laser beams — which will be based here on Earth, at least initially, in Breakthrough Starshot's plan — they may veer wildly off course from their targets. Now scientists have designed and tested a new sail that could in principle automatically keep itself centered on a laser beam for the required few minutes, allowing a spacecraft to stay on course for interplanetary or even interstellar journeys.

The protests began October 14, 2019 and as the protests have raged, the repression unleashed on demonstrators has become increasingly brutal and high-tech. The video shows the drone, a police unmanned aerial system (UAS), hovering above a sea of demonstrators as the green lasers are trained on it. Soon, multiple other lasers are trained on it and when the drone attempts to escape, the lasers have an almost tractor beam-like effect, forcing the UAS to falter before it helplessly descends to the ground.
