A little while ago the operations to connect the BEAM expandable module to the International Space Station were completed. The operation lasted about four hours during which the Canadarm2 robotic arm was used to transport BEAM from the unpressurized section of the Dragon spacecraft to the Tranquillity module. At that point, it was berthed to the Station via remote control, just like they do with the cargo spacecraft. This is only the first phase of its installation, which will proceed slowly, step by step.
