The seven orbital residents of the Two cosmonauts are gearing up to exit the station’s Poisk module tomorrow at 1:55 p.m.
Coolant Leak Contamination Risk Measures
As a result of detailed analysis of contamination risk after a coolant loop leak occurred on the backup radiator of the Nauka multipurpose laboratory module, the At the end of the Roscosmos spacewalk on Wednesday, October 25, before reentering the Poisk airlock, the two spacewalking cosmonauts as usual will inspect the Roscosmos Orlan spacesuits and the tools used during the spacewalk to look for signs of coolant and wipe off any coolant as necessary. The cosmonauts also will wipe down their suits and tools as usual after repressurization to further reduce introduction of trace contaminates into the space station environment. Additional filtration will then be used inside the space station in order to quickly scrub the atmosphere of any remaining traces of contaminant.
Upgrades and Preparation for Subsequent Spacewalk
Flight Engineer Loral O’Hara of NASA teamed up with Commander Andreas Mogensen of ESA (exit the station on Monday, October 30 at 8:05 a.m. to remove the Radio Frequency Group and replace hardware on a solar array. The duo spent some time reviewing procedures and collecting and configuring tools they’ll use during their six-and-a-half-hour excursion. In the evening, Moghbeli operated tomography hardware and scanned O’Hara’s eyes for the ongoing CIPHER investigation. CIPHER, or Complement of Integrated Protocols for Human Exploration Research, is an all-encompassing, total-body approach that examines how humans adapt to spaceflight.
