Two spacewalkers and their assisting crew members took a half-day off on Friday following the previous day’s excursion to remove radio hardware and swab for microbes outside the International Space Station. The rest of the Expedition 72 crew researched plasma physics, took a physical fitness test, and ensured the upkeep of the orbital outpost.

Station Commander Suni Williams and Flight Engineer Butch Wilmore took Friday morning off sleeping in after conducting a five-hour and 26-minute spacewalk on Thursday. The duo worked in the vacuum of space removing a radio frequency group assembly and collecting samples of potential microbes living on the outside of the station for analysis. During that same spacewalk Williams surpassed Peggy Whitson’s record for most total spacewalking time by a female of 60 hours and 21 minutes. Williams now has 62 hours, 6 minutes of total spacewalk time, fourth on NASA’s all-time list.

Williams and Wilmore then spent Friday afternoon servicing their spacesuits and cleaning the Quest airlock where they staged Thursday’s spacewalk. At the end of the workday, the pair was joined by NASA Flight Engineers Nick Hague and Don Pettit for a standard conference with mission controllers discussing issues or concerns they may have experienced during the spacewalk. Hague and Pettit, the day before, had assisted the spacewalkers in and out of their spacesuits and operated the Canadarm2 robotic arm.

Williams total spacewalking time is now 62 hours and six minutes over nine spacewalks. Wilmore has completed five spacewalks reaching 31 hours and two minutes of total spacewalking time.

Expedition 72’s other three crewmates, Roscosmos Flight Engineers Aleksandr Gorbunov, Alexey Ovchinin, and Ivan Vagner, had a busy day studying space physics, pedaling on an exercise cycle, and installing new electronics gear.

Gorbunov reviewed operations for the Plasma Kristall-4 experiment that observes the behavior of complex plasmas in microgravity. The plasmas contain electrons, ions, neutral gas, and microparticles that interact strongly when charged and can turn into plasma crystals. Next, he installed a video monitor in the Columbus laboratory module to support the plasma crystal study.

Ovchinin and Vagner started their day pedaling on an exercise cycle for an hour each while attached to sensors measuring their health data. The regularly scheduled fitness tests help researchers understand how microgravity affects a crew member’s body. The duo then spent the second half of their day continuing to install new command and telemetry gear inside the Zvezda service module.

Spacewalk preparations and space gardening were the main duties aboard the International Space Station on Tuesday. The seven Expedition 72 crewmates also serviced electronics systems and packed a cargo craft for its upcoming departure.

Commander Suni Williams and Flight Engineer Butch Wilmore began their day with standard health checks required for astronauts getting ready for a spacewalk. The duo checked vital signs including temperature, blood pressure, and breathing rate then transferred the data to a tablet computer for review by doctors on the ground. Both astronauts later gathered inside the Quest airlock and continued to gather and organize their spacewalking hardware including tethers, pistol grip tools, and other task-specific gear.

Williams and Wilmore are due to set their spacesuits to battery power at 8 a.m. EST on Thursday signifying the official start time of the second spacewalk of 2025. The two NASA astronauts will exit Quest and spend about six-and-a-half hours removing radio communications hardware and searching for microbes outside the orbital outpost. NASA+ will begin its live spacewalk coverage at 6:30 a.m.

NASA Flight Engineer Nick Hague participated in the spacewalk preparations Tuesday collecting the hardware necessary to remove the radio frequency group antenna assembly. Next, he photographed the tools Williams and Wilmore staged inside Quest for documentation. Hague wrapped up his shift reconfiguring computer network hardware then resupplying medical kits with blood tubes, needles, gloves, and more inside the Human Research Facility racks.

NASA Flight Engineer Don Pettit spent his day working on space agricultural hardware to learn how to grow food in space and sustain future crews on long-term missions to the Moon, Mars, and beyond. The four-time station visitor first watered thale cress plants growing to understand the effects of microgravity and ultraviolet radiation on plant life. Afterward, Pettit removed research components from inside the Advanced Plant Habitat that recently hosted a small crop of red lettuce that was harvested and preserved and will soon be tested for its nutritional value.

Exercise research, cargo packing, and lab maintenance topped the schedule for the cosmonauts working in the Roscosmos segment of the orbiting lab. Flight Engineer Aleksandr Gorbunov attached electrodes to himself and jogged on a treadmill for a physical fitness evaluation in the Zvezda service module. Flight Engineer Alexey Ovchinin spent his day loading trash and discarded gear inside the Progress 89 cargo craft due to depart Zvezda next month. Flight Engineer Ivan Vagner spent his day inside Zvezda installing new command and telemetry hardware that can communicate with Soyuz and Progress spacecraft, ground stations, and orbiting satellites.

Preparations continue for a spacewalk to remove communications hardware and check for microbes outside the International Space Station later this week. Meanwhile, the Expedition 72 crew harvested red lettuce for a space agriculture study and continued its upkeep of the orbital outpost.

Commander Suni Williams and Flight Engineer Butch Wilmore are scheduled to begin a six-and-a-half-hour spacewalk at 8 a.m. EST on Thursday. The NASA astronauts will remove a degraded radio frequency group antenna assembly and collect samples of potential microbes living outside of the orbital outpost. The duo reviewed on Monday the Canadarm2 robotic arm procedures necessary to support the removal of the degraded radio communications gear.

Flight Engineers Nick Hague and Don Pettit will be at the controls of the Canadarm2 on Thursday assisting and monitoring the spacewalkers. The two NASA astronauts also studied the robotics procedures and practiced on a computer the maneuvers they will use to guide the spacewalkers during their external maintenance activities.

There was still time during the day for Wilmore and Hague to join each other in the Kibo laboratory module and pick a small crop of red lettuce from the Advanced Plant Habitat. Wilmore started the harvesting job collecting the leaves, packing them in pouches, and stowing the samples in a science freezer for later analysis. Pettit finished the botany operations extracting roots from the Plant Habitat, collecting water samples for analysis, and photographing the research hardware. The botany investigation is assessing the nutritional value of food grown in space and may promote growing crops on future missions.

Williams and Pettit partnered together inside the Permanent Multipurpose Module (PMM) cleaning and organizing a variety of cargo including food, electronics gear, science experiments and more. The PMM was launched to the station on space shuttle Discovery and installed on Unity module’s Earth-facing port March 1, 2011. PMM was relocated May 27, 2015, to its current location on the Tranquility module’s forward port.

Earth observations, space navigation, and lab maintenance topped the schedule for the three cosmonauts working in the orbiting lab’s Roscosmos segment. Flight Engineer Aleksandr Gorbunov outfitted a camera with specialized hardware and photographed Earth landmarks to study the effects natural and man-made catastrophes.

The week ended aboard the International Space Station with spacesuit maintenance and research into how microgravity affects blood pressure and breathing. The Expedition 72 residents also serviced a variety of hardware supporting science experiments and life support systems aboard the orbital outpost.

Two NASA astronauts, Commander Suni Williams and Flight Engineer Butch Wilmore, continued gearing up for a spacewalk scheduled to begin at 8 a.m. EST on Thursday, Jan. 30. Williams worked throughout Friday in the Quest airlock completing the charging of lithium-ion batteries that power spacesuits for the duration of a spacewalk. Next, she filtered and cleaned the water loops that cool astronauts in their spacesuits in the extreme environment of outer space. Wilmore pitched in and verified the functionality of spacesuit components including glove heaters, cameras, and helmet lights. The duo is preparing for a six-and-a-half-hour spacewalk next week to remove radio antenna hardware and search for microbes outside the orbital outpost.

NASA Flight Engineer Nick Hague began his day inside the Columbus laboratory module installing experiment containers on the BioLab, a biology research device that enables observations of microbes, cells, tissues, and more in weightlessness. NASA Flight Engineer Don Pettit activated life support gear in the Unity module and removed more life support hardware from the Tranquility module. The pair later met at the end of the day and reviewed procedures they will use in the future to service the external thermal control system that cools hardware on the outside of the orbital lab.

Roscosmos Flight Engineers Alexey Ovchinin and Ivan Vagner started their day on human research. This time, Ovchinin wore sensors that measured his exhalation following a deep breath helping doctors understand how microgravity affects the respiratory system. Vagner wore a separate set of sensors for a study observing how a crew member’s vascular system functions during a long-term space mission. Cosmonaut Aleksandr Gorbunov spent the first part of his day on orbital plumbing tasks in the Nauka science module then wrapped up his shift auditing stowage space throughout the station’s Roscosmos segment.

The Expedition 72 crew took a break from spacewalk preparations on Thursday and focused on combustion and biology research. The seven orbital residents also worked on housecleaning duties and lab maintenance ensuring the upkeep of the International Space Station.

Station Commander Suni Williams turned her attention to cleaning crew quarters and filming an educational video following several days of preparing for her spacewalk with NASA Flight Engineer Butch Wilmore. Williams first cleaned ducts, fans, and air sensors inside the Harmony module’s port side crew quarters. Next, she filmed a video demonstrating how water moves and evaporates in microgravity for students and teachers on Earth.

Wilmore worked in the Unity module and inventoried tools that fellow NASA Flight Engineers Nick Hague and Don Pettit will use to support the spacewalkers next week. Williams and Wilmore are planning to begin a spacewalk at 8 a.m. EST on Jan. 30 to remove radio antenna hardware and search for microbes outside the orbital outpost. Hague and Pettit will help the spacewalking duo in and out of the spacesuits, in and out of the Quest airlock, and maneuver the Canadarm2 robotic arm during the planned six-and-a-half-hour excursion.

Hague had the first half of his day off before he spent the second part of his shift cleaning ducts, fans, and air sensors inside Harmony’s overhead crew quarters. Pettit worked throughout the day configuring research hardware inside the Combustion Integrated Rack for a spacecraft fire safety investigation.

Roscosmos Flight Engineers Alexey Ovchinin and Ivan Vagner began their day working on separate human research experiments. Ovchinin attached sensors to himself measuring how microgravity affects a crew member’s vascular function. Vagner participated in a breathing study that monitors crews for potential space-caused respiratory system issues.

Cosmonaut Aleksandr Gorbunov inventoried hardware stowed throughout the space station’s Roscosmos segment then serviced an oxygen generator in the Zvezda service module. Next, he installed and configured observation hardware to image Earth’s nighttime atmosphere in near-ultraviolet wavelengths.

Spacewalk preparations continue aboard the International Space Station to remove communications gear and search for microbes next week. The Expedition 72 crew members also worked on a host of advanced science experiments and housecleaning duties throughout the day on Wednesday.

Station Commander Suni Williams and Flight Engineer Butch Wilmore are slated to begin their spacewalk at 8 a.m. EST on Jan. 30 and spend about six-and-a-half hours removing a radio frequency group antenna assembly and searching for microbes on the orbital outpost. The duo kicked off their day inside the Quest airlock reviewing their spacewalk procedures and servicing their spacesuit helmets. Afterward, Williams and Wilmore checked the fuel and power capacity of their SAFER or Simplified Aid for EVA Rescue. A spacewalker would use the SAFER installed on their spacesuit to maneuver back to the station in the unlikely event they became untethered from the station.

NASA Flight Engineers Nick Hague and Don Pettit will assist the spacewalkers next week and studied on Wednesday the spacewalking tasks and the Canadarm2 robotic maneuvers they will use to support the removal of the radio communications gear. Hague, with Pettit as backup, will be at the controls of the Canadarm2 carefully guiding Williams, who will be attached to the robotic arm’s tip, or latching end effector. Pettit and Hague will also help the spacewalkers in and out of their spacesuits, guide the duo in and out of Quest, and monitor the spacewalking activities.

At the end of their shifts, the four NASA astronauts regrouped inside the Harmony module to clean up and reorganize cargo. The quartet disposed of trash, relocated hardware to gain more space, and conducted a photographic inspection of Harmony for analysis on the ground.

More Earth observations and advanced space piloting studies were on the schedule aboard the orbiting lab’s Roscosmos segment. Flight Engineer Aleksandr Gorbunov first set up a camera with a spectrometer and pointed it out a window on the Zvezda service module to photograph the effects of Earth disasters in numerous wavelengths. Next, he strapped on a sensor-packed cap that recorded his reactions as he practiced on a computer spacecraft and robotic piloting techniques crew members may use on future planetary missions.

Roscosmos Cosmonaut Alexey Ovchinin began his shift servicing audio and ventilation systems in the Zvezda and Zarya modules then wrapped his day exploring 3D printing tools in microgravity. Flight Engineer Ivan Vagner spent his day activating video gear and uninstalling electronics hardware before taking a questionnaire documenting his experience communicating with international crews and mission controllers from around the world.
