The CRS-9 mission slated to launch Monday morning at 12:45 EDT will carry an International Docking Adapter that will provide a vital link between the International Space Station and the new spacecraft in development with NASA’s Commercial Crew Program. Big enough for astronauts to float through, the segment is outfitted with sensors and devices that are designed to allow arriving spacecraft to dock automatically without astronauts steering them in themselves. Spacewalkers will position the docking ring on the end of the station where it will be in place for the first flight tests by the new generation of human-rated spacecraft.
