NASA successfully tests microwave thruster, paving the way for speedier space travel
As with airplanes and many other self-powered machines, the fuel a shuttle engine requires can weigh nearly as much as the object it's propelling, increasing costs while significantly limiting range. It's a challenge we're going to need to overcome before launching long-distance treks through space, where carrying enough fuel may not currently be possible. One proposed method for getting future spacecrafts to their destinations is by utilizing a device called a microwave thruster. A British scientist named Roger Shawyer managed to build a similar engine called an EmDrive several years ago, and while a Chinese team also accomplished the same, the rest of the world hasn't paid much attention until NASA confirmed from its own research that such a device could work during a presentation earlier this week.
