The first of two International Docking Adapters (designated IDA-2 since IDA-1 was lost in the one and only Falcon 9 launch mishap to date) has, by now, been extracted from the trunk of the CRS-9 Dragon spacecraft and should be hovering about three feet away from the Pressurized Mating Adapter 2 (PMA-2) on the forward end of the ISS, secure in the grip of the SSRMS. It will stay there until Friday, when astronauts Jeff Williams and Kate Rubins will exit the Quest airlock and work to get the adapter properly installed. NASA has released this wonderful informative CGI video outlining the plan for Friday’s spacewalk.
If you want to watch it live, tune in to NASA TV (via cable, satellite, YouTube, the NASA TV website, or wherever else you can find a feed) on Friday. Live coverage starts at 6:30 AM EDT (10:30 UTC), and the actual spacewalk is scheduled to begin at 8:05 AM EDT.
