Roscosmos is planning a spacewalk, dubbed Russian EVA-45a, in part to investigate the recent microcrack discovered on the Orbital Module of Soyuz MS-09. During the outing, two cosmonauts are expected to egress from the Pirs module and make their way to the Soyuz to peel back the thermal covering around the hole, which was sealed in late August by the crew of Expedition 56.
The spacewalk is currently expected to be performed by Expedition 57 Russian cosmonauts Oleg Kononenko and Sergey Prokopyev and will likely about six hours starting at 16:03 UTC Dec. 11, 2018.
According to NASA, the cosmonauts are expected to take samples of any residue found on the hull and capture images of the area before placing a new thermal blanket over it. Once that is completed, the duo is expected to retrieve science experiments from the Rassvet module before returning to Pirs to conclude the spacewalk.
Kononenko will be wearing a spacesuit with red stripes and be known as extravehicular crew member 1 — the lead spacewalker — while Prokopyev will wear a spacesuit with blue stripes and be known as EV2. It will be Kononenko’s fourth spacewalk and Prokopyev’s second.
NASA expects to air the spacewalk live on NASA TV starting around 15:00 UTC.
