International Space Station managers have rescheduled a pair of spacewalks as they continue to review data from a backup radiator leak that has since ceased. In the meantime, the Expedition 70 crew members had a busy day at the end of the week packed with space research, cargo operations, and more spacewalk preparations.

The next U.S. spacewalk at the orbiting laboratory will take place at 8:35 a.m. EDT on Thursday, Oct. 19. Astronauts Loral O’Hara from NASA and Andreas Mogensen from ESA (European Space Agency) will spend about six-and-a-half hours swabbing station surfaces to collect potential samples of microbes that might survive in the extreme environment of outer space. NASA TV will begin its spacewalk coverage at 7 a.m. on the agency’s app and website.

A second U.S. spacewalk with O’Hara and NASA Flight Engineer Jasmin Moghbeli has been targeted for Oct. 30. The NASA duo will spend about six-and-a-half hours in the vacuum of space removing faulty radio communications gear and installing new solar array hardware.

The trio along with Flight Engineer Satoshi Furukawa from JAXA (Japan Aerospace Exploration Agency) took a pause from their spacewalk activities on Friday. The astronauts refocused their attention on human research and botany while also keeping up electronics and life support maintenance.

O’Hara took a robotics test and provided biological samples for an experiment to understand the psychological and physiological changes an astronaut experiences while living in weightlessness. Furukawa checked carbon dioxide bottles and hoses that support the growth environment inside the Advanced Plant Habitat botany research facility.

Moghbeli began her day transferring cargo in and out of the Cygnus space freighter. She then cleaned the Human Research Facility’s centrifuge chamber before servicing a variety of computers throughout the orbital lab. Mogensen spent Friday collecting water samples for ground analysis from life support systems in the space station’s U.S. segment.

Two Roscosmos cosmonauts are stepping up their preparations for a spacewalk planned to begin at 4:20 p.m. on Oct. 25. Five-time lab resident Oleg Kononenko and first-time space flyer Nikolai Chub will exit the Poisk airlock in their Orlan spacesuits to install new hardware and deploy a nanosatellite. The pair ended the week studying their spacewalk procedures and testing support hardware.

Flight Engineer Konstantin Borisov began Friday training to maneuver the European robotic arm attached to the Nauka science module. Afterward, Borisov opened panels inside Nauka and photographed internal hardware configurations in anticipation of future experiments.

Two United States operating segment spacewalks outside the International Space Station have been rescheduled for no earlier than Thursday, Oct. 19, and Monday, Oct. 30, as a result of ongoing review by NASA managers and engineers after a coolant leak from a backup radiator on the station’s Nauka multipurpose laboratory module.

The spacewalks were deferred from their original target dates to allow engineers additional time to complete their analysis of the coolant leak, which occurred on Oct. 9 and has now stopped.

During the first spacewalk NASA astronaut Loral O’Hara and ESA (European Space Agency) astronaut Andreas Mogensen will exit the station’s Quest airlock to collect samples for analysis to see whether microorganisms may exist on the exterior of the orbital complex. They also will replace a high-definition camera on the port truss of the station and conduct other maintenance work to prepare for future spacewalks.

O’Hara will serve as extravehicular activity (EVA) crew member 1 and will wear a suit with red stripes. Mogensen will serve as extravehicular crew member 2 and will wear an unmarked suit. U.S. Spacewalk 89 will be the first spacewalk for both crew members.

During the second spacewalk, O’Hara and Jasmin Moghbeli will complete the removal of a faulty electronics box, called a Radio Frequency Group, from a communications antenna bracket and replace one of twelve Trundle Bearing Assemblies on the port truss Solar Alpha Rotary Joint. The bearings enable the station’s solar arrays to rotate properly to track the sun as the station orbits the Earth. During this spacewalk, Moghbeli will serve as EVA crew member 1 and O’Hara will serve as EVA crew member 2. U.S. Spacewalk 90 will be the first spacewalk for Moghbeli and second for O’Hara.

Details on times for the spacewalks are being reviewed and times for live coverage on NASA Television, the agency’s website and the NASA app and will be shared once available.

Cargo operations and maintenance filled the Expedition 70 crew’s day as International Space Station managers and engineers continued reviewing the ceased leak data. In the meantime, two cosmonauts are also gearing up for their own spacewalk.

Astronauts Loral O’Hara of NASA and Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) were back on cargo duty Thursday morning. The duo continued unpacking cargo from the Cygnus space freighter and loaded trash and discarded items for disposal aboard the commercial cargo craft. Cygnus delivered several tons of science and supplies on Aug. 2 and will depart the station and complete its mission in December.

O’Hara also worked on the Cold Atom Lab completing the installation of new science components and reconnection of cables on the quantum physics research device. Furukawa collected drinking water samples for processing and analysis in the Destiny laboratory module.

Commander Andreas Mogensen of ESA (European Space Agency) along with NASA Flight Engineer Jasmin Moghbeli spent a few moments on Thursday checking out spacesuit components including safety jetpacks and other gear. Mogensen would also photograph the condition of the Columbus laboratory module and perform educational science activities. Moghbeli inspected and cleaned hatch seals in the station’s U.S. segment then cleared away items blocking ventilation systems and narrowing passage between modules.

Cosmonauts Oleg Kononenko and Nikolai Chub continued preparing for their spacewalk scheduled on Oct. 25 to install new hardware and deploy a nanosatellite. The pair from Roscosmos collected and organized their spacewalking tools inside the Poisk airlock where the planned six-hour and 45-minute spacewalk will begin. Kononenko also jogged on the Zvezda service module’s treadmill for in a physical fitness evaluation. Chub worked in Nauka testing the performance of laptop computers.

Roscosmos Flight Engineer Konstantin Borisov spent most of his day on a variety of maintenance tasks as he serviced life support gear and panels inside the Nauka module. Borisov also transferred water from the Progress 85 cargo craft into the station and jogged on the treadmill for a fitness test after Kononenko.

NASA engineering and flight control teams are continuing to review data and video associated with a coolant leak from a backup radiator on the station’s Nauka multipurpose laboratory module (MLM). Two United States segment spacewalks originally scheduled for Thursday, Oct.12, and Friday, Oct. 20, have been postponed until the review is complete. New dates will be announced later.

The leak has now ceased, as was reported by Roscosmos flight controllers and evidenced by NASA external station camera views, which show only residual coolant droplets.

The primary radiator on Nauka continues to work normally, providing full cooling to the module with no impacts to the crew or to space station operations.

The backup radiator was delivered to the space station on the Rassvet module during space shuttle mission STS-132 in 2010. It was transferred to the Nauka during a Roscosmos spacewalk in April.

Teams on the ground continue to investigate the cause of the leak, and additional updates will be made as soon as available.

Meanwhile, cargo operations and maintenance rounded out the day aboard the International Space Station.

All seven orbital lab residents began Wednesday morning weighing themselves in microgravity. While the space environment renders objects and humans weightless, they still have mass. The crew uses a specialized device that applies a known force to a crew member and measures the resulting acceleration to accurately calculate their mass.

The international septet then split up for the rest of the day moving on to a variety of activities in preparation for upcoming spacewalks. Astronauts Loral O’Hara of NASA and Andreas Mogensen of ESA (European Space Agency) will exit the space station and swab station surfaces to determine the types of microbes that might survive the extreme conditions of outer space. They will be supported by fellow astronauts Jasmin Moghbeli of NASA and Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) who will assist the spacewalkers before, during, and after the scheduled six-hour excursion.

Cosmonauts Oleg Kononenko and Nikolai Chub are also getting ready for a spacewalk together planned at the end of the month to install new hardware and deploy nanosatellites. The duo spent Wednesday morning studying the procedures planned for the six-hour and 45-minute spacewalk. After lunchtime, the Roscosmos flight engineers began collecting their spacesuit components and organizing spacewalking tools.

Amidst the spacewalk prep work today, O’Hara, Mogensen and Furukawa also took turns transferring cargo in and out of the Cygnus space freighter berthed to the Unity module’s Earth-facing port. Cygnus launched to the orbital outpost on Aug. 1, carrying food, fuel, supplies, and new science experiments to study gene therapy, atmospheric density, spacecraft fire safety, and more. The cargo craft from Northrop Grumman is due to end its mission and depart in December.

Cosmonaut Konstantin Borisov spent his day supporting life support and electronics maintenance. The first-time space flyer finalized a session of carbon dioxide monitoring and readied radiation detectors that will be worn on spacesuits on an upcoming spacewalk. He also charged camcorder batteries and reconfigured video cameras.

The Expedition 70 crew worked throughout Tuesday on space physics and human research aboard the International Space Station. Two astronauts are also gearing up for a spacewalk on Thursday to determine if microorganisms can survive the harsh environment of outer space.

Tuesday morning, the orbital residents focused their science activities on a variety of physics research hardware. NASA astronaut Loral O’Hara installed new components and reconnected power and data cables on the Cold Atom Lab, a device that observes the quantum behavior of atoms chilled to near absolute zero. Flight Engineer Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) set up combustion experiment gear in the Kibo laboratory module to study how microgravity affects flames and improve fire safety on spacecraft.

O’Hara then joined fellow NASA Flight Engineer Jasmin Moghbeli in the Columbus laboratory module for vein scans. Moghbeli operated the Ultrasound 2 device and scanned O’Hara’s neck, shoulder, and leg veins with assistance from doctors on the ground.

At the end of the day, both astronauts joined up with Furukawa and Commander Andreas Mogensen of ESA (European Space Agency) and discussed robotics procedures planned for Thursday’s spacewalk. Moghbeli and Furukawa will be at the controls of the Canadarm2 robotic arm assisting O’Hara and Mogensen when they exit the station on Thursday for a six-hour spacewalk that starts at 10 a.m. EDT.

Mogensen and O’Hara earlier worked in the Quest airlock organizing the spacewalking tools they will use on Thursday to swab station surfaces and determine if microbes can live in the external conditions of microgravity. Moghbeli and Furukawa trained on a computer for the robotics maneuvers necessary to support the spacewalkers.

Two cosmonauts worked on a pair of technology studies exploring 3D printing and space navigation on Tuesday. Flight Engineer Nikolai Chub tested the on-demand manufacturing, or 3D printing, of tools in microgravity to help crews become less dependent on supplies launched from Earth. Flight Engineer Konstantin Borisov photographed landmarks on Earth for an experiment collecting data to improve high-precision data for determining the location of the space station.

Veteran cosmonaut Oleg Kononenko spent Tuesday working inside the Progress 85 (85P) cargo craft docked to the aft port of the Zvezda service module. The five-time station visitor first transferred water stowed inside the 85P into liquid containers aboard the Roscosmos segment of the orbiting lab. Afterward, Kononenko unpacked cargo from the 85P, stowed the new supplies in the appropriate station modules, and updated inventory systems.

The coolant leak from a backup radiator on the station’s Nauka Multipurpose Laboratory Module (MLM) has ceased, as was reported by Roscosmos flight controllers and evidenced by NASA external station camera views, which show only residual coolant droplets.

The primary radiator on Nauka continues to work normally, providing full cooling to the module with no impacts to the crew or to space station operations.

The radiator was delivered to the space station on the Rassvet module during space shuttle mission STS-132 in 2010. It was transferred to the Nauka during a Roscosmos spacewalk in April.

International Space Station Operations Update

At approximately 1 p.m. EDT Oct. 9, NASA flight controllers in mission control at the agency’s Johnson Space Center in Houston, using cameras on the International Space Station exterior, observed flakes emanating from one of two radiators on the Roscosmos Nauka Multipurpose Laboratory Module (MLM). The flight control team informed the crew aboard the space station of the potential leak, and NASA astronaut Jasmin Moghbeli confirmed the presence of the flakes from the cupola windows, after which the crew was asked to close the shutters on U.S. segment windows as a precaution against contamination.

The crew aboard station was never in any danger.

Roscosmos confirmed that the observed leak is on Nauka’s backup radiator, which is mounted to the outside of the module. The radiator was delivered to the space station on the Rassvet module during space shuttle mission STS-132 in 2010. It was transferred to the Nauka during a Roscosmos spacewalk in April. The primary radiator on Nauka is working normally, providing full cooling to the module with no impacts to the crew or to space station operations.

Teams on the ground will continue to investigate the cause of the leak, and additional updates will be made as available.

Spacesuit preparations took a break on Thursday as the Expedition 70 crew turned its attention it to human research including behavioral studies, eye exams, and a fitness evaluation. The International Space Station residents also focused on an array of science hardware maintenance and orbital plumbing tasks.

NASA astronaut Loral O’Hara spent her day participating in the CIPHER human research study to understand how living in space affects an astronaut’s mind and body. She practiced simulated robotics maneuvers on a computer to assess changes in her cognition and brain function. She also processed blood and urine samples for insights into her immune and heart health. The experiment is observing the combined effects of radiation, isolation, long distances, microgravity, and closed environments on crews.

Two flight engineers, Jasmin Moghbeli of NASA and Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency), had a busy day of science hardware work, robotics training, and eye checks. Moghbeli started her schedule replacing components on the Cold Atom Lab and inspecting the quantum physics research facility. Furukawa began his shift configuring cameras and lights that will be installed outside the space station later. The pair then joined each other after lunch reviewing robotics procedures for an upcoming spacewalk. Finally, Furukawa examined Moghbeli’s eyes using standard medical imaging gear found in a doctor’s office on Earth.

NASA managers will discuss two spacewalks scheduled for Oct. 12 and 20 for science and maintenance at 1 p.m. EDT on Friday on NASA TV. For the first spacewalk, astronauts O’Hara and Andreas Mogensen from ESA (European Space Agency) will collect external microbe samples for analysis. The second spacewalk will see O’Hara and Moghbeli remove and replace communications and solar array hardware.

Mogensen, commander of Expedition 70, spent Thursday afternoon in the Tranquility module servicing life support components. Before that, he joined his crewmates Moghbeli and Furukawa, and Roscosmos cosmonaut Konstantin Borisov for a medical emergency training session. The astronauts gathered together locating medical hardware, coordinating rescue roles, and practicing cardiopulmonary resuscitation, or CPR, as part of the training session. The foursome launched to the orbital lab as members of the SpaceX Crew-7 mission on Aug. 26, 2023.

Earlier, cosmonaut Nikolai Chub assisted Borisov as he attached sensors to himself and pedaled on an exercise cycle for a physical fitness evaluation. Doctors evaluate the downlinked exercise data to understand a crew member’s aerobic and cardiovascular conditioning in weightlessness. Chub would spend the rest of the day on electronics and computer maintenance.

The orbiting lab’s most experienced crew member, cosmonaut and five-time station visitor Oleg Kononenko, started his day in the Zvezda service module replacing orbital plumbing parts. Afterward, Kononenko swapped gases for a space physics study and synchronized clocks on cameras to station computers.
