NASA astronauts Scott Kelly and Kjell Lindgren ended their spacewalk at 2:10 p.m. EST with the repressurization of the U.S. Quest airlock. The astronauts restored the port truss (P6) ammonia cooling system to its original configuration, the main task for today’s spacewalk. They also returned ammonia to the desired levels in both the prime and back-up systems.
In a minor departure from the planned tasks, the astronauts ran out of time to cinch and cover a spare radiator known as the Trailing Thermal Control Radiator. The radiator, which Lindgren retracted earlier in the spacewalk, was fully redeployed and locked into place in a dormant state.

The radiator had been deployed during a November 2012 spacewalk by astronauts Sunita Williams and Aki Hoshide as they tried to isolate a leak in the truss’ cooling supply by re-plumbing the system to the backup radiator. The leak persisted and was subsequently traced to a different component that was replaced during a spacewalk in May 2013.

The 7 hour and 48 minute spacewalk was the second for both astronauts, and the 190th in support of assembly and maintenance of the orbiting laboratory. Crew members have now spent a total of 1,192 hours and 4 minutes working outside the orbital laboratory.

On-Orbit Status Report

Extravehicular Activity (EVA) #33: Kelly and Lindgren egressed the Airlock at 5:22am CST in order to perform P6 Return To Original Configuration (RTOC) EVA #33. The Phased Elapsed Time (PET) for today’s EVA was 7 hours and 48 minutes. The objectives for the EVA that were completed are as follows:

– Open Photo Voltaic Radiator (PVR) 2B Flight Quick Disconnect Coupling (FQDC)
– P3/P4 Ammonia Jumper Install
– Reconfigure Ammonia Tank Assembly (ATA) Vent Panel for Ammonia Fill
– Early External Thermal Control System (EETCS)/Photovoltaic Thermal Control System (PVTCS) Fill
– Reconfigure P5/P6 Jumpers for Ammonia Fill
– Trailing Thermal Control Radiator (TTCR) Retract
– P1/P5 Ammonia Fill Line Vent
– P3/P4 Jumper Stow
– Starboard Crew Equipment Translation Aid (CETA) Cart Reconfig
– Alpha Joint Interface Structure (AJIS) Strut Bolt Torque and MLI Reconfiguration

The TTCR cinch and shroud task was deferred because the EVA was running long. Instead, the TTCR was re-deployed so that it would be in a stable long term configuration. In addition, only one of the two AJIS strut bolt torques was completed. Following the EVA, ISS is in a stable configuration.

Reaction Self Test: Kelly will complete a Reaction Self Test session prior to his sleep period tonight. This session and the sessions completed yesterday were scheduled to provide data in close time proximity to today’s extravehicular activity (EVA). Reaction Self Test helps crewmembers objectively identify when their performance capability is degraded by various fatigue-related conditions that can occur as a result of ISS operations and time in space (e.g., acute and chronic sleep restriction, slam shifts, EVA, and residual sedation from sleep medications).

Soret Facet: A run was completed last night for JAXA’s Soret Facet investigation. The Soret effect in fluids is a thermodynamic phenomenon in which different particles respond in different ways to varying temperatures. The effect has been difficult to examine in detail on Earth because of convection effects in gravity conditions. This is the first investigation to verify Soret conditions in steady and changing conditions that supports a comparison of the Soret effects in microgravity to effects observed on the ground.
