The seven orbital residents saved busy on Tuesday getting ready for a spherical of upcoming spacewalks. Whereas reviewing procedures and prepping instruments had been on the forefront of right this moment’s duties, the Expedition 70 crew members additionally had a while for station upkeep actions and well being exams.
Two cosmonauts are gearing as much as exit the station’s Poisk module tomorrow at 1:55 p.m. EDT for a deliberate seven-hour spacewalk. Flight Engineers Nikolai Chub and Oleg Kononenko of Roscosmos had a light-weight obligation morning earlier than getting ready the Orlan fits they are going to put on outdoors of the station to put in communications {hardware}, deploy a nanosatellite, and examine the exterior backup radiator that skilled a coolant leak.
Because of detailed evaluation of contamination threat after a coolant loop leak occurred on the backup radiator of the Nauka multipurpose laboratory module, the NASA and Roscosmos groups have agreed to implement publish spacewalk procedures to cut back traces of coolant from getting into the Worldwide Area Station. The evaluation, imagery evaluate, and different testing carried out has concluded that the portions of contaminate getting into house station and threat to techniques is predicted to be very low. Nevertheless, the mitigations had been agreed to in an abundance of warning to maintain the chance as little as doable for {hardware} contained in the house station. On the finish of the Roscosmos spacewalk Wednesday, Oct. 25, earlier than reentering the Poisk airlock, the 2 spacewalking cosmonauts as traditional will examine the Roscosmos Orlan spacesuits and the instruments used throughout the spacewalk to search for indicators of coolant and wipe off any coolant as vital. The cosmonauts additionally will wipe down their fits and instruments as traditional after repressurization to additional cut back introduction of hint contaminates into the house station surroundings. Extra filtration will then be used contained in the house station with a view to rapidly scrub the environment of any remaining traces of contaminant.
Flight Engineer Loral O’Hara of NASA teamed up with Commander Andreas Mogensen of ESA (European Area Company) within the morning to wrap up the set up of the brand new Teal CEVIS system, an improve to the International Space Station’s bicycle. The 2 then cut up up duties, O’Hara shifting onto prep for subsequent week’s spacewalk with Flight Engineer Jasmin Moghbeli of NASA.
Each first-time spacewalkers will exit the station on Monday, Oct. 30 at 8:05 a.m. to take away the Radio Frequency Group and change {hardware} on a photo voltaic array. The duo spent a while reviewing procedures and gathering and configuring instruments they’ll use throughout their six-and-a-half-hour tour. Within the night, Moghbeli operated tomography {hardware} and scanned O’Hara’s eyes for the continuing CIPHER investigation. CIPHER, or Complement of Built-in Protocols for Human Exploration Analysis, is an all-encompassing, total-body method that examines how people adapt to spaceflight.
After breakfast, Flight Engineer Satoshi Furukawa of JAXA (Japan Aerospace Exploration Company) prepped cargo for return on SpaceX’s 29th cargo mission scheduled for launch no sooner than Nov. 5. Afterwards, Furukawa was joined by Mogensen to evaluate robotics procedures they are going to use subsequent week when O’Hara and Moghbeli are outdoors of the orbital lab.
Following this, Flight Engineer Konstantin Borisov of Roscosmos was joined by Chub and Kononenko late afternoon for inspections and assessments of the Nauka module.
