Additional filtration will then be used inside the space station in order to quickly scrub the atmosphere of any remaining traces of contaminant. The cosmonauts also wiped down their suits and tools as usual after repressurization to further reduce introduction of trace contaminates into the space station environment. One of four panels on the radar system was not able to be fully deployed during the spacewalk and the work will be deferred to a future date.Īt the end of the spacewalk, before reentering the Poisk airlock, the two spacewalking cosmonauts as usual inspected 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 installed a synthetic radar communications system. The two cosmonauts also released a nanosatellite to test solar sail technology however, the nanosatellite’s solar sail failed to deploy as far as cameras could track its departure from the station. During the radiator inspection, a bubble of coolant liberated at the leak site and the crew wiped down their suits prior to continuing the spacewalk. EDT after 7 hours and 41 minutes.ĭuring the spacewalk, Kononenko and Chub inspected and photographed an external backup radiator on the Nauka multipurpose laboratory module, as well as isolated the radiator from Nauka’s cooling system. Roscosmos cosmonauts Oleg Kononenko and Nikolai Chub concluded their spacewalk Oct. Subscribe here: Cosmonauts Oleg Kononenko (red stripes) and Nikolai Chub (blue stripes) prepare a synthetic radar communications system for installation during their seven-hour and 41-minute spacewalk.

Borisov would later collect air samples for analysis and configure life support gear in the Nauka science module. Flight Engineers Oleg Kononenko, Nikolai Chub, and Konstantin Borisov awoke mid-afternoon and conducted post-spacewalk cleanup activities then held a conference with specialists on the ground. The orbiting lab’s three cosmonauts slept in Thursday following a seven-hour and 41-minute spacewalk the day before. He later scanned the neck, shoulder, and leg veins of Mogensen using the Ultrasound 2 device with assistance from doctors on the ground. Next, Furukawa prepared a microscope to observe how cells respond to weightlessness. The two-time station visitor first took a cognition test measuring how long-term space missions impact a crew member’s brain structure and function. Mogensen analyzed station air samples then transferred data collected from wearable health-monitoring gear.įurukawa had time throughout the day to focus on a variety of science activities including examining microgravity’s effects on astronauts and setting up a biology microscope. Moghbeli spent a few moments on research maintenance removing a failed electronic unit from a science freezer and packing it for stowage. O’Hara began her day installing communications hardware to support a laser technology study. The pair was also joined by astronauts Andreas Mogensen of ESA (European Space Agency) and Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) reviewing their spacewalk procedures during the afternoon. O’Hara and Moghbeli worked throughout Thursday checking tools and readying hardware they will take with them outside the Quest airlock for the maintenance spacewalk. O’Hara will serve as extravehicular crew member 2 and will wear an unmarked suit. Moghbeli will serve as extravehicular activity crew member 1 and will wear a suit with red stripes. Spacewalk 89 will be the first for both Moghbeli and O’Hara. The spacewalk was previously planned for Monday, Oct. The bearings enable the station’s solar arrays to track the Sun. They also will replace one of 12 trundle bearing assemblies on the station’s port solar alpha rotary joint. NASA astronauts Loral O’Hara and Jasmin Moghbeli will exit the station’s Quest airlock to remove an electronics box called the Radio Frequency Group that was part of a communications antenna system. 1, to allow the International Space Station crew and flight control team additional time to prepare for the excursion. The next United States orbital segment spacewalk now is scheduled for Wednesday, Nov. The Expedition 70 crew is gearing up for another spacewalk planned at the beginning of November for maintenance on the outside of the International Space Station. Cosmonauts Oleg Kononenko (suit with red stripes) and Nikolai Chub (suit with blue stripes) are pictured during a spacewalk for maintenance on Oct.
