<\/a>The seven orbital residents kept busy on Tuesday preparing for a round of upcoming spacewalks. While reviewing procedures and prepping tools were at the forefront of today\u2019s tasks, the Expedition 70<\/a> crew members also had some time for station maintenance activities and health exams.<\/p>\n Two cosmonauts are gearing up to exit the station\u2019s Poisk module tomorrow at 2:20 p.m. for a planned seven-hour spacewalk<\/a>. Flight Engineers Nikolai Chub and Oleg Kononenko of Roscosmos had a light duty morning before preparing the Orlan suits they will wear outside of the station to install communications hardware, deploy a nanosatellite, and inspect the external backup radiator that experienced a coolant leak<\/a>.<\/p>\n 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 NASA and Roscosmos teams have agreed to implement post spacewalk procedures to reduce traces of coolant from entering the International Space Station. The analysis, imagery review, and other testing performed has concluded that the quantities of contaminate entering space station and risk to systems is expected to be very low. However, the mitigations were agreed to in an abundance of caution to keep the risk as low as possible for hardware inside the space station. At the end of the Roscosmos spacewalk Wednesday, Oct. 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.<\/p>\n Flight Engineer Loral O\u2019Hara<\/a> of NASA teamed up with Commander Andreas Mogensen<\/a> of ESA (European Space Agency) in the morning to wrap up the installation of the new Teal CEVIS system, an upgrade to the International Space Station<\/a>\u2019s bicycle. The two then split up duties, O\u2019Hara moving onto prep for next week\u2019s spacewalk with Flight Engineer Jasmin Moghbeli<\/a> of NASA.<\/p>\n Both first-time spacewalkers will exit the station<\/a> on Monday, Oct. 30 at 8:05 a.m. EDT 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\u2019ll use during their six-and-a-half-hour excursion. In the evening, Moghbeli operated tomography hardware and scanned O\u2019Hara\u2019s eyes for the ongoing CIPHER<\/a> 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<\/a>.<\/p>\n After breakfast, Flight Engineer Satoshi Furukawa<\/a> of JAXA (Japan Aerospace Exploration Agency) prepped cargo for return on SpaceX\u2019s 29th<\/sup> cargo mission scheduled for launch no earlier than Nov. 5. Afterwards, Furukawa was joined by Mogensen to review robotics procedures they will use next week when O\u2019Hara and Moghbeli are outside of the orbital lab.<\/p>\n Following this, Flight Engineer Konstantin Borisov of Roscosmos was joined by Chub and Kononenko late afternoon for inspections and assessments of the Nauka<\/a> module.<\/p>\n Learn more about station activities by following the space station blog<\/a>, @space_station<\/a> and @ISS_Research<\/a> on X, as well as the ISS Facebook<\/a> and ISS Instagram<\/a> accounts.<\/p>\n Get weekly video highlights at: https:\/\/roundupreads.jsc.nasa.gov\/videoupdate\/<\/a><\/p>\n Get the latest from NASA delivered every week.
