Tuesday Sees Space Physics, Human Research, and Spacewalk Preps

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.

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

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) at the orbital complex. 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.

Astronauts Prepare for Two October Spacewalks

Spacewalk preparations topped the schedule for the Expedition 70 crew aboard the International Space Station on Friday. NASA managers previewed the spacewalks at the end of the week that will see astronauts exiting the orbital lab to collect microbe samples and service a variety of hardware.

Flight Engineer Loral O’Hara of NASA and space station Commander Andreas Mogensen of ESA (European Space Agency) will exit the space station on Oct. 12 for a planned six-hour spacewalk. The duo will swab external station surfaces with specialized tools collecting samples of microorganisms for analysis. Scientists will process the samples to determine the types of microbes that may survive in the vacuum of space.

The duo was joined on Friday by astronauts Jasmin Moghbeli of NASA and Satoshi Furukawa of JAXA (Japan Aerospace Exploration Agency) to continue preparing for their mission’s first spacewalk. The foursome called down to specialists on the ground and reviewed the upcoming spacewalk’s procedures. All four astronauts also studied the robotics activities necessary to support the microbe-sampling spacewalk. Moghbeli and Furukawa will maneuver the Canadarm2 robotic arm during the excursion, monitor the astronauts during their spacewalk, and help the spacewalkers in and out of their spacesuits.

NASA managers previewed the upcoming spacewalk activities on NASA TV on Friday. They also highlighted a second spacewalk scheduled for Oct. 20 when O’Hara will exit the space station with Moghbeli. The two NASA astronauts will spend about six-and-a-half hours in the vacuum of space removing faulty radio communications gear and installing new solar array hardware.

Human Research Ahead of Spacewalk Preview on NASA TV

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.

Spacesuits, Research, and Treadmill Work Top Crew’s Day

The Expedition 70 crew continues preparing for a pair of spacewalks for science and maintenance outside the International Space Station. The orbital residents are also studying space piloting, observing Earth, and working on a treadmill today.

NASA astronaut Loral O’Hara and ESA (European Space Agency) astronaut Andreas Mogensen are getting ready for their first spacewalk set to begin at 10 a.m. EST on Oct. 12. The duo will use specialized tools to collect microbe samples from specific areas outside of the station. Scientists want to analyze the types of microbes that may be able to survive the harsh environment of outer space.

NASA TV will broadcast both a spacewalk preview briefing and the upcoming spacewalks. The preview briefing, set for 1 p.m. EDT on Friday, will highlight next week’s spacewalk activities, as well as another spacewalk scheduled for Oct. 20 with O’Hara and fellow NASA astronaut Jasmin Moghbeli. The Oct. 12 spacewalk broadcast begins at 8:30 a.m.

O’Hara and Mogensen tried on their spacesuits today with assistance from Moghbeli and JAXA (Japan Aerospace Exploration Agency) astronaut Satoshi Furukawa. The duo tested the suits’ communication capabilities with ground controllers and practiced using some of the tools and procedures they will use during the microbe-sampling spacewalk. Moghbeli and Furukawa will assist the duo in and out of their spacesuits and monitor their spacewalking activities next week.

The three Roscosmos flight engineers split their day with a variety of space science and maintenance activities. Veteran cosmonaut Oleg Kononenko attached sensors to himself measuring his responses as he practiced docking a spacecraft on computer. The study aims to keep station crew members familiar with piloting a spacecraft and train crews for future missions. First-time cosmonaut Konstantin Borisov pointed his camera towards Earth and photographed forests to monitor the effects of natural and human activities.

Kononenko then joined Nikolai Chub, also a first-time cosmonaut, and spent the afternoon working on regularly scheduled maintenance on a treadmill inside the Zvezda service module. Chub and Borisov also worked on a variety of electronics and life support maintenance throughout the orbital lab’s Roscosmos segment.
