As an outcome of in-depth analysis of contamination threat after a coolant loop leakage happened on the backup radiator of the Nauka multipurpose laboratory module, the NASA and Roscosmos groups have actually agreed to execute post-spacewalk treatments to lower traces of coolant from going into the International Space Station. The analysis, imagery review, and other testing performed has actually concluded that the quantities of contaminate entering space station and risk to systems is expected to be really low. The mitigations were concurred to in an abundance of caution to keep the threat as low as possible for hardware inside the area station.

The seven orbital residents of the International Space Station kept hectic on Tuesday, October 24, preparing for a round of upcoming spacewalks. While evaluating treatments and prepping tools were at the forefront of todays tasks, the Expedition 70 crew members likewise had a long time for station upkeep activities and health examinations.
Two cosmonauts are tailoring up to exit the stations Poisk module tomorrow at 1:55 p.m. EDT for a planned seven-hour spacewalk. Flight Engineers Nikolai Chub and Oleg Kononenko of Roscosmos had a light responsibility early morning before preparing the Orlan fits they will wear beyond the station to set up interactions hardware, release a nanosatellite, and check the external backup radiator that experienced a coolant leak.
Coolant Leak Contamination Risk Measures
As a result of detailed analysis of contamination danger after a coolant loop leakage occurred on the backup radiator of the Nauka multipurpose lab module, the NASA and Roscosmos groups have actually concurred to implement post-spacewalk treatments to lower traces of coolant from going into the International Space Station. The analysis, imagery review, and other screening performed has concluded that the quantities of contaminate going into spaceport station and risk to systems is anticipated to be extremely low. However, the mitigations were accepted in an abundance of caution to keep the danger as low as possible for hardware inside the area station.
The cosmonauts likewise will wipe down their suits and tools as typical after repressurization to even more decrease introduction of trace infects into the space station environment.( From left) Expedition 70 Commander Andreas Mogensen of ESA (European Space Agency); and Flight Engineers Loral OHara and Jasmin Moghbeli, both from NASA; and Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency), posture for a picture aboard the International Space Stations Destiny lab module.
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 utilized during the spacewalk to search for signs of coolant and rub out any coolant as essential. The cosmonauts likewise will wipe down their matches and tools as normal after repressurization to even more reduce intro of trace infects into the spaceport station environment. Additional filtration will then be used inside the spaceport station in order to rapidly scrub the atmosphere of any staying traces of contaminant.

Upgrades and Preparation for Subsequent Spacewalk
Flight Engineer Loral OHara of NASA partnered with Commander Andreas Mogensen of ESA (European Space Agency) in the morning to cover up the installation of the brand-new Teal CEVIS system, an upgrade to the International Space Stations bike. The two then broke up responsibilities, OHara moving onto preparation for next weeks spacewalk with Flight Engineer Jasmin Moghbeli of NASA.
Both first-time spacewalkers will leave the station on Monday, October 30 at 8:05 a.m. to get rid of the Radio Frequency Group and replace hardware on a solar range. The duo invested a long time gathering and reviewing procedures and setting up tools theyll use throughout their six-and-a-half-hour expedition. In the evening, Moghbeli operated tomography hardware and scanned OHaras eyes for the ongoing CIPHER examination. CIPHER, or Complement of Integrated Protocols for Human Exploration Research, is an all-encompassing, total-body method that takes a look at how people adapt to spaceflight.
Regular Duties and Nauka Module Inspection
After breakfast, Flight Engineer Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) prepped freight for return on SpaceXs 29th cargo mission arranged for launch no earlier than November 5. Afterward, Furukawa was signed up with by Mogensen to review robotics treatments they will use next week when OHara and Moghbeli are outside of the orbital lab.
Following this, Flight Engineer Konstantin Borisov of Roscosmos was joined by Chub and Kononenko late afternoon for assessments and assessments of the Nauka module.
