Starliner docks with ISS for the first time

Boeing’s CST-100 Starliner spacecraft successfully docked with the International Space Station May 20, a little more than 24 hours after its launch. The spacecraft docked with the forward docking port on the Harmony module of the station at 8:28 p.m. Eastern. Controllers reported a hard docking securing the spacecraft to the station about 20 minutes later, although hatches separating the spacecraft from the station won’t open until around 11:45 a.m. Eastern May 21.
