Spacewalking Expedition 25 Flight Engineers Fyodor Yurchikhin and Oleg Skripochka are floating briskly through the tasks planned for them outside the International Space Station. They began Russian Spacewalk #26 about 30 minutes later than scheduled but are about 30 minutes ahead of the timeline after installing a multipurpose workstation on the right side of the Zvezda service module for use by future spacewalkers. Their next task is to remove a robotics experiment from the left side of Zvezda.
Yurchikhin and Skripochka began their planned 5-hour, 55-minute spacewalk at 9:54 a.m. EST.
The primary assembly and maintenance objectives of the spacewalk are to install a multipurpose workstation on the starboard side of the Zvezda service module’s large-diameter section, clean thermal insulation around the vents for the Elektron oxygen-generation system and relocate a television camera from one end of the Rassvet docking compartment to the other.
Research objectives include 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 the exterior of Zvezda and Pirs.
