NEW YORK (AP) — A nearly silent, drone-sized aircraft has shown it can fly, thanks to a scientist who was inspired by watching "Star Trek" as a child. With neither propellers nor jets, the airplane gets its thrust by applying a strong electric field to the air. That general idea has been...

This illustration made available by NASA in October 2016 shows an illustration of NASA's InSight lander about to land on the surface of Mars. NASA's InSight spacecraft will enter the Martian atmosphere at supersonic speed, then hit the brakes to get to a soft, safe landing on the alien red plains. After micromanaging every step of the way, flight controllers will be powerless over what happens at the end of the road, nearly 100 million miles away. (NASA/JPL-Caltech via AP
