NASA International Space Station On-Orbit Status 1 September 2016.

Expedition 48 Commander Jeff Williams and Flight Engineer Kate Rubins concluded their spacewalk at 2:41 p.m. EDT.

During the six-hour, 48-minute spacewalk, the two NASA astronauts successfully retracted a thermal radiator, installed two enhanced high definition cameras on the station's truss and tightened bolts on a joint that enables one of the station's solar arrays to rotate.

Space station crew members have conducted 195 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 1,217 hours and 34 minutes working outside the station.

On-Orbit Status Report

Trailing Thermal Control Radiator (TTCR) Extravehicular Activity (EVA): Today, CDR Williams and FE-6 Rubins completed the TTCR EVA, with Airlock egress at 6:53 am CDT. Once outside the Airlock, the crew performed the following scheduled tasks:

- Retract, cover, and cinch down the TTCR using hook straps
- Replace a failed External Television Camera Group (ETVCG) light at the Camera Port 9 (CP9) location
- Install a High Definition Camera in the CP9 location
- Re-torque the Alpha Joint Interface Structure (AJIS) Struts on the Port 4 (P4) truss
- Perform an inspection Solar Alpha Rotary Joint (SARJ)
- Port 6 (P6) Pump Flow and Control System (PFCS) Multi-Layer Insulation (MLI) Tie-back

The crew was ahead on the timeline, so they were also able to install an additional High Definition Camera at the CP8 location, and perform the Port Crew and Equipment Translation Aid (CETA) Cart Brake Handle Tie-Down task. While Williams and Rubin were outside, FE-5 Onishi operated the Space Station Remote Manipulator System (SSRMS) and assisted with the tasks. The EVA duration was 6 hours, 48 minutes.

Mobile Servicing System (MSS) Operations for EVA: Today Robotics Ground Controllers powered up the MSS to support the TTCR EVA. Once the EVA crew completed the TTCR retract, FE-5 maneuvered the SSRMS into position to install an Articulating Portable Foot Restraint (APFR) on the SSRMS Latching End Effector (LEE). CDR ingressed the APFR, and the SSRMS was maneuvered to allow CDR to change the light of the CP9 (P1 Lower Outboard (LOOB)) camera then again to position CDR to install an External High Definition Camera (EHDC) on the CP9 camera. Once the CP9 tasks had been completed, the SSRMS was maneuvered to position CDR to install an EHDC on the CP8 (P1 Upper Outboard (UPOB)) camera. Once this had been completed, the SSRMS was moved to a park position. MSS performance today was nominal.
