Watch live as NASA astronauts spacewalk to install a new automated docking ring on the ISS

NASA astronauts Nick Hague and Andrew Morgan are setting out today to perform the installation of a new International Docking Adapter (IDA) on the International Space Station that will provide another way for future crew craft flown by commercial providers to bring astronauts to the orbital research platform. This is the second IDA to be installed on the ISS, and the actual spacewalk itself is set to happen at 8:20 AM ET, with astronauts spending the time until then getting all suited up. The adapter will provide automated docking procedures for a number of future crew spacecraft, including Boeing's CST-100 Starliner and the SpaceX Crew Dragon, and it's a standard that's intended to be used with any other commercial craft to be developed with the aim of reaching the ISS in the future.
