NASA astronauts Jeff Williams and Kate Rubins are getting ready for Thursday morning’s spacewalk scheduled to begin at 8:05 a.m. EDT and last 6.5 hours. NASA Television will provide complete coverage beginning at 6:30 a.m. EDT.

The two astronauts will retract a thermal radiator that is part of the station’s cooling system. They will 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.

This will be the 195th spacewalk in support of space station assembly and maintenance, the fifth of Williams’ career and the second for Rubins.
