Crew Enjoys Light-Duty Day, Debriefs Spacewalk

Four International Space Station residents had a light-duty day Thursday as they enjoyed some time off and worked on close out procedures following the conclusion of yesterday’s spacewalk. The three other Expedition 74 crew members spent the day inspecting various modules of the orbital complex, cleaning, and stowing cargo.

NASA astronauts Jessica Meir and Chris Williams concluded a seven-hour, two-minute spacewalk yesterday at 3:54 p.m. EDT, completing their primary objectives which included preparing the 2A power channel for the future installation of roll-out solar arrays. It was Meir’s fourth spacewalk and Williams’ first.

The spacewalkers, along with NASA astronaut Jack Hathaway and European Space Agency (ESA) astronaut Sophie Adenot, enjoyed the morning off. Hathaway and Adenot, who monitored yesterday’s spacewalk and assisted Meir and Williams with donning and doffing their suits, joined the duo in the afternoon for a post-spacewalk debrief with ground teams.

Later in the evening, Williams completed some spacesuit work, performed a water recharge and reset a torque wrench. Meir also worked in some time for health research, collecting biological samples for analysis, routine work that helps scientists take a closer look at the effects of spaceflight on the human body.

In the Roscosmos segment, the three cosmonauts spent the day exercising, inspecting modules, cleaning, and stowing cargo. In the morning, flight engineer Andrey Fedyaev exercised on the station’s treadmill before moving throughout the station to collect radiation sensors. Once gathered, he logged radiation measurements for analysis.

In the Zarya module, flight engineer Sergei Mikaev inspected and photographed lighting units for documentation, then vacuumed the space. He later moved into the Nauka module to record ventilation fan operations for possible repairs in the future. Meanwhile, Commander Sergey Kud-Sverchkov performed various inspections in the Zvezda Service Module before teaming up with Mikaev to gather and load cargo items into the Progress 93 cargo spacecraft for future disposal.

Astronauts Install Solar Array Mod Kit, Complete Spacewalk

NASA astronauts Jessica Meir and Chris Williams concluded their spacewalk outside the International Space Station at 3:54 p.m. EDT. It was Williams’ first spacewalk and Meir’s fourth.

During the approximately seven-hour and two-minute spacewalk, Meir and Williams completed their primary objectives, which included preparing the 2A power channel. This work will enable the future installation of roll-out solar arrays to provide additional power for the orbiting laboratory, supporting critical systems and its safe, controlled deorbit.

The duo also completed additional tasks, including installing a 2A power system jumper cable, and adjusting bolt torque on a battery box. The remaining tasks, including installing a lens cover on a camera attached to the station’s Canadarm2 robotic arm and swabbing for microorganisms near the Quest airlock, will be moved to a future spacewalk.

Spacewalkers Exit Station for Solar Array Mod Kit Install

NASA astronauts Jessica Meir and Chris Williams began a spacewalk at 8:52 a.m. EDT to prepare the 2A power channel for the future installation of new roll-out solar arrays. Once installed, the arrays will provide additional power for the orbiting laboratory, supporting critical systems and its safe, controlled deorbit.

Spacewalkers Prep to Install Solar Array Mod Kit Today

Live coverage is underway as two NASA astronauts prepare for a spacewalk outside the International Space Station. The spacewalk is scheduled to last about six and a half hours.

Coverage is available on NASA+, Amazon Prime, and the agency’s YouTube channel. Learn how to stream NASA content through a variety of online platforms, including social media.

During the spacewalk, NASA astronauts Jessica Meir and Chris Williams will exit the station’s Quest airlock to prepare the 2A power channel for the future installation of International Space Station Roll-Out Solar Arrays. Once installed, the array will provide additional power for the orbital laboratory, including critical support of its safe and controlled deorbit.

Meir will serve as spacewalk crew member 1, wearing a suit with red stripes. Williams will serve as crew member 2, wearing an unmarked suit. This spacewalk will be Williams’ first and Meir’s fourth.

Crew Wraps Final Spacewalk Preparations

Tuesday brought the final preparations for tomorrow’s spacewalk where two NASA astronauts will exit the International Space Station and enter the vacuum of space for space station solar array upgrade work. The Expedition 74 crew members prepped spacesuits and reviewed procedures while working in some time for maintenance and science activities.

NASA astronauts Jessica Meir and Chris Williams will power on their spacesuits tomorrow morning for a planned six-and-a-half-hour spacewalk. The duo will exit the Quest airlock to install a modification kit and route cables on the port side of the station. It will be Meir’s fourth spacewalk and Williams’ first.

NASA’s live coverage will begin at 6:30 a.m. on  NASA+, Amazon Prime, and the agency’s YouTube channel. U.S. spacewalk 94 will begin at approximately 8 a.m. 

To gear up for tomorrow’s spacewalk, Meir and Williams readied their spacesuits and equipment and also finalized the configuration of tools they’ll use while in the vacuum of space. Later on, the duo was joined by NASA astronaut Jack Hathaway and European Space Agency (ESA) astronaut Sophie Adenot to review procedural timelines and checklists.

Hathaway and Adenot teamed up throughout the day to complete a round of camera and lighting training. The duo also inspected and cleaned the orbital complex’s ventilation system.

In the cupola, Adenot scheduled in some time to photograph the Moon. As part of the Earthshine experiment, crew members will take photographs of the lunar surface during different phases to study changes in Earth’s reflectance of light. The photos are then analyzed by ground teams to help scientists improve climate models. 

In the morning, Commander Sergey Kud-Sverchkov worked with flight engineer Sergei Mikaev to load up and prepare flight simulation training software. Later on, the two cosmonauts worked in the Zvezda Service Module to gather equipment for future inspections. Kud-Sverchkov then took inventory of cargo to be loaded into the Progress 93 cargo spacecraft while Mikaev filmed his crewmates as they conducted science, maintenance, and exercise to document life aboard the space station. Flight engineer Andrey Fedyaev spent his day conducting maintenance before attaching sensors to his forehead, fingers and toes to capture blood flow data for health analysis.
