SpaceX’s science-laden Dragon cargo spaceship hooks up with space station

News Brief: Three days after its launch, SpaceX’s robotic Dragon cargo capsule is now attached to the International Space Station. Astronauts used the station’s robotic arm to capture the spaceship at 3:54 a.m. PT today and pull it in for its berthing. Over the course of the next month, the crew will unload nearly three tons of supplies and science experiments — including a free-flying, AI-enabled robotic companion called CIMON, an apparatus for cultivating space algae and dozens of student experiments.
