SpaceX capsule delivers new station docking port
SpaceX is working on a crew-worthy Dragon, while Boeing is developing a capsule for astronauts named Starliner. The two U.S. space station residents used a robot arm for Wednesday’s 250-mile-high operation above America’s Great Lakes. The newly arrived science experiments include a DNA decoderthat will get a workout by the first virus-hunter in space, NASA astronaut Kate Rubins.
