Expedition 25 Flight Engineers Fyodor Yurchikhin and Oleg Skripochka ended Monday’s spacewalk at 4:22 p.m. EST. The excursion lasted six hours and 27 minutes.
The primary assembly and maintenance objectives of the spacewalk were to install a multipurpose workstation on the starboard side of the Zvezda service module’s large-diameter section and relocate a television camera from one end of the Rassvet docking compartment to the other.
Research objectives included cleaning and removing a robotics experiment known as Kontur, short for Development of a System of Supervisory Control Over the Internet of the Robotic Manipulator in the Russian Segment of ISS, from the port side of Zvezda into the Pirs airlock; installing a new materials experiment on a handrail on the Rassvet module, and collecting samples from underneath insulation on the exterior of Zvezda and Pirs.
Skripochka and Yurchikhin completed all the tasks except the relocation of the television camera due to interference with insulation where it was to be installed.
