Początek US EVA-90: 12:45 UTC (14:45 CEST).
Michael Barratt został zatem amerykańskim rekordzistą w ilości najkrótszych EVA.
Do niego należy także najkrótsza EVA.
Formalnie można uznać, że średnia wieku uczestników EVA okazała się rekordowo wysoka i wyniosła 59,5 l (chociaż niedoszli spacerowicze nie wydostali się fizycznie poza obręb śluzy).
Po częściowej wymianie składu w ekipie mającej brać udział w EVA, wiadomo, u którego astronauty pojawiła się anomalia ze skafandrem.
The agency elected to change out Dominick with Barratt as the spacesuits on board are already sized for Barratt, and to decide later who to schedule for a scheduled July 2 spacewalk.

Barratt began Tuesday morning troubleshooting Dyson’s spacesuit and inspecting the suit’s components. Afterward, he joined Dyson for ongoing procedure reviews with fellow astronauts Matthew Dominick and Jeanette Epps for future spacewalks. (...)
The Crew Flight Test duo replaced the pressure control and pump assembly motor that supports the space station’s main restroom, also known as the waste and hygiene compartment, in the Tranquility module.

Cargo, Science, and Spacewalk Preps Fill Station’s DayMark Garcia Posted on June 26, 2024
Dyson and Barratt continued spacesuit and tool configurations in the Quest airlock.
At the end of the workday, the four NASA astronauts gathered in the Destiny laboratory module for a video conference with mission controllers on the ground. The quartet called down to the NASA engineers and discussed procedures and readiness for an upcoming spacewalk.
NASA’s Boeing Crew Flight Test astronauts Butch Wilmore and Suni Williams started their morning with exercise sessions before organizing cargo packed inside the Permanent Multipurpose Module. The duo then spent the afternoon working to remove and replace a failed pressure control and pump assembly module that is part of the Tranquility module’s bathroom, or waste and hygiene compartment.

Shortly after 9 p.m. EDT, @NASA instructed crews aboard the space station to shelter in their respective spacecraft as a standard precautionary measure after it was informed of a satellite break-up at an altitude near the station’s earlier Wednesday. Mission Control continued to monitor the path of the debris, and after about an hour, the crew was cleared to exit their spacecraft and the station resumed normal operations.

Early indications are that a non-operational Russian spacecraft, Resurs P1 (SATNO 39186), released a number of fragments between 13:05 UTC 26 June and 00:51 UTC 27 June.

NASA Collins xEVAS UpdateMark Garcia Posted on June 26, 2024
After a thorough evaluation, NASA and Collins Aerospace have mutually agreed to descope the existing task orders on the Collins Exploration Extravehicular Activity Services contract. This descope includes ending the International Space Station suit demonstration, which was targeted for 2026. No further work will be performed on the task orders. This action was agreed upon after Collins recognized its development timeline would not support the space station’s schedule and NASA’s mission objectives.
This change to the xEVAS contract has no impact on NASA’s spacewalking capabilities on the space station. Collins will continue to support NASA’s EMU (Extravehicular Activity Mobility Unit) spacesuit and is committed to supporting space station’s ongoing spacewalking capabilities through the existing Extravehicular Space Operations Contract.

Ongoing Spacewalk Preps, Science, and Plumbing Keep Crews BusyMark Garcia Posted on June 27, 2024
NASA Flight Engineers Tracy C. Dyson and Mike Barratt began Thursday morning reviewing procedures for a spacewalk that will see hardware replacements and installations, preparations for future upgrades on science gear, and photographic inspections of station pipelines. After lunchtime, the two astronauts turned on a computer that visualized the upcoming spacewalk tasks using 3D graphics. NASA will release an advisory soon announcing the spacewalking details and NASA TV coverage times.
NASA Flight Engineers Matthew Dominick and Jeanette Epps had a busy day with spacesuit maintenance, computer updates, and orbital plumbing. Dominick then worked in the Quest airlock during the afternoon recharging spacesuit batteries and dumping and filling the suit water tanks. Epps swapped out a hard drive on a science laptop computer then replaced plumbing components in the Tranquility module’s bathroom, also called the water and hygiene compartment.

Crews Wrap Week; Managers Provide Starliner, Spacewalk, and Cargo UpdatesMark Garcia Posted on June 28, 2024
At the end of the day, Epps operated standard medical imaging gear found in an optometrist’s office on Earth and peered into Dyson’s eyes. She examined Dyson’s cornea, retina, and lens to help flight surgeons understand and counteract microgravity’s effect on crew vision.
Earlier, Dyson collected and stowed excess space station hardware for disposal. Epps spent her morning inside the Kibo laboratory module troubleshooting an airflow sensor then reorganizing the JAXA (Japan Aerospace Exploration Agency) module for upcoming cargo operations. (...)
NASA is now targeting the end of July for the next spacewalk outside the space station. This change allows teams on the ground to continue to troubleshoot and understand the water leak in the service and cooling umbilical unit that forced an early end to a spacewalk on Monday, June 24.

Crews Wrap Week; Managers Provide Starliner, Spacewalk, and Cargo UpdatesMark Garcia Posted on June 28, 2024
Robotics controllers are scheduled to detach the Cygnus space freighter from the Unity module on July 12 and release it into Earth orbit for disposal over the South Pacific Ocean ending a five-and-a-half-month mission at the orbital lab.

Station Orbiting Higher; Routine Upkeep for CrewAbby Graf Posted on July 1, 2024
Starliner’s Commander and Pilot, Butch Wilmore and Suni Williams, spent the morning in the Permanent Multipurpose Module, organizing stowage and tidying up. Wilmore then moved into the Japanese Experiment Module to disassemble an empty NanoRacks CubeSat Deployer in preparation of upcoming NanoRacks missions.
Later on, Wilmore prepped and viewed samples for Moon Microscope, a demonstration that allows flight surgeons on Earth to diagnose illnesses and could provide diagnostic capabilities for crews on future missions to the Moon and Mars. Meanwhile, Williams conducted some routine orbital plumbing, then audited U.S. stowage items housed inside the Zarya module.
The next spacewalk outside the orbiting complex is scheduled for July 29 with Dyson and Barratt.

Routine Health Assessments and Cargo Ops Top Tuesday’s ScheduleAbby Graf Posted on July 2, 2024 Expedition 71
Barratt and Dyson teamed up in the afternoon to deconfigure spacesuit components after a water leak in Dyson’s service and cooling umbilical unit forced an early end to a spacewalk on Monday, June 24. The next spacewalk outside of the orbiting laboratory, with Dyson and Barratt, is scheduled for July 29.
Later in the evening, Barratt received an eye exam, guided by Epps, to help researchers better understand how microgravity affects vision. Meanwhile, Dyson was joined by Crew Flight Test Commander Butch Wilmore to load trash and discarded gear inside Northrop Grumman’s Cygnus spacecraft. Cygnus is scheduled to be released from the Unity module later this month for disposal over the South Pacific Ocean, ending its five-and-a-half month stay at the orbiting lab.
Crew Flight Test Pilot Suni Williams spent a majority of the day on Starliner operations then assessed the air flow of the pump filter attached to the Advanced Plant Habitat. At the end of the day, Williams was joined by all eight of her crewmates for a conference with ground teams.
All three cosmonauts in microgravity donned acoustic monitors throughout the day to capture sound measurements around the station. In the Zvezda Service Module, Flight Engineer Nikolai Chub tested a 3D printer to assess its ability to manufacture space hardware, then later inspected and photographed panels and cable routes of a Roscosmos physics experiment that examines neutron radiation.
