Spacewalkers Oleg Kononenko (left pic from February 2012) and Sergey Prokopyev (right pic from August 2018) will examine the Soyuz MS-09 spacecraft that will return three Expedition 57 crew members to Earth Dec. 19.
Expedition 57 Flight Engineers Oleg Kononenko and Sergey Prokopyev of Roscosmos are preparing to venture outside the International Space Station for a spacewalk at approximately 11 a.m. EST on Tuesday, Dec. 11. NASA Television coverage is now underway and available on the agency’s website.
Over the course of about six hours, the duo will use this spacewalk to examine a section of the external hull of the Soyuz MS-09 spacecraft currently docked to station, and if time permits, retrieve external experiments.
In late August, a pressure leak occurred from the space station that was traced to the Soyuz. Within hours after finding the source of the leak, crew members sealed the hole and the station has since maintained steady pressure.
The cosmonauts will take samples of any residue found on the hull and take digital images of the area before placing a new thermal blanket over it. The samples and images will provide additional information that will aid the investigation in the cause of the pressure ...
