WATCH LIVE: American astronauts install HD cameras onto ISS during spacewalk
NASA astronauts Jeff Williams and Kate Rubins will take a spacewalk Thursday outside of the International Space Station (ISS).
The walk is scheduled to begin at 8:10 a.m. EDT and last for 6.5 hours.
The duo embarked on a spacewalk August 19, installing the first International Docking Adapter (IDA), a new docking port that will enable the future arrival of U.S. commercial crew spacecraft.

According to NASA:
Williams and Rubins will retract a thermal radiator that is part of the station's cooling system. The radiator is a backup that had been deployed previously as part of an effort to fix an ammonia coolant leak. They'll also tighten struts on a solar array joint, and install the first of several enhanced high-definition television cameras that will be used to monitor activities outside the station, including the comings and goings of visiting cargo and crew vehicles.
