NASA spacewalkers (from left) Bob Behnken and Chris Cassidy set up the outside of the Tranquility module for the future installation of the NanoRacks airlock.

NASA astronauts Robert Behnken and Chris Cassidy concluded their spacewalk at 12:41 p.m. EDT, after five hours and 29 minutes. The two NASA astronauts completed a number of tasks designed to upgrade International Space Station systems.

They began by installing a protective storage unit that includes two Robotic External Leak Locator (RELL) units the Canadian Space Agency's Dextre robot can use to detect leaks of ammonia, which is used to operate the station's cooling system.

Behnken and Cassidy then removed two lifting fixtures at the base of station solar arrays on the near port truss, or backbone, of the station. The "H-fixtures" were used for ground processing of the solar arrays prior to their launch.

They then completed tasks to prepare the outside of the Tranquility module for the arrival later this year of the Nanoracks commercial airlock on a SpaceX cargo delivery mission. After its installation, the airlock will enable be used to deploy commercial and government-sponsored experiments into space.

They also routed ethernet cables and removed a lens filter cover from an external camera.

This was the 10th spacewalk for each astronaut, tying them with Michael Lopez-Alegria and Peggy Whitson as the only other U.S. astronauts to complete 10 spacewalks. Behnken has now spent a total of 61 hours and 10 minutes spacewalking. Cassidy now has spent a total of 54 hours and 51 minutes spacewalking.

Space station crew members have conducted 231 spacewalks in support of assembly and maintenance of the orbiting laboratory. Spacewalkers have now spent a total of 60 days, 12 hours, and 3 minutes working outside the station.

Астронавты NASA завершили второй за неделю выход в открытый космос

НЬЮ-ЙОРК, 21 июля. /ТАСС/. Американские астронавты Крис Кэссиди и Роберт Бенкен завершили во вторник второй за последние пять дней выход в космос с борта Международной космической станции (МКС). Трансляция операции шла на сайте Национального управления США по аэронавтике и исследованию космического пространства (NASA).

За пять часов 20 минут работы в открытом космосе астронавты установили на корпусе станции платформу RiTS (Robot Tool Stowage), где будут храниться две роботизированные системы RELL (Robotic External Leak Locators), способные выявлять утечки газов из корпуса станции. Они также демонтировали узел H-fixture у основания фермы, на которой установлены солнечные батареи, который не удалось снять во время выхода в космос 1 июля, когда Боб Бенкен перепробовал несколько инструментов для того, чтобы открыть крышку, слишком плотно прилегающую к корпусу.

Астронавты провели на американском модуле Tranquility подготовительные работы для установки нового шлюза. Как указывается на сайте NASA, шлюз будет доставлен на МКС грузовым кораблем Dragon позднее в этом году и будет использоваться при осуществлении коммерческих исследовательских программ NanoRacks. Кроме того, астронавты протянули интернет-кабель по корпусу станции.

Во время следующего выхода в космос астронавты должны будут заменить одну литий-ионную батарею, в работе которой были выявлены неполадки.

Spacewalkers prep space station for future upgrades
July 21, 2020 | William Harwood

STORY WRITTEN FOR CBS NEWS & USED WITH PERMISSION

Space station commander Chris Cassidy and Robert Behnken floated back outside Tuesday for their fourth spacewalk in less than a month, completing preparations for future upgrades including the eventual installation of an airlock that will allow commercial experiments to be moved into and out of vacuum as required.

The astronauts originally planned four spacewalks to install replacement batteries in the station's solar power system, but that work was completed ahead of schedule during three excursions on June 26, July 1 and July 16. The fourth spacewalk was replanned as a result, and mission managers added a variety of unrelated tasks.

Floating in the Quest airlock, Cassidy and Behnken switched their spacesuits to battery power at 7:12 a.m. EDT to officially kick off the 231st spacewalk in station history, the seventh so far this year and the 10th for both astronauts.

When the excursion ended five hours and 29 minutes later, at 12:41 p.m., Behnken's total spacewalk time stood at 61 hours and 10 minutes over his 10 excursions, moving him up to No. 4 on the list of most experienced spacewalkers. Cassidy's total of 54 hours and 51 minutes across his 10 excursions moved him up to No. 9.

Their experience paid off during their four spacewalks together and Tuesday's work was no exception. They got right to work, and shortly after floating out of the airlock, Cassidy installed a robotics tool box on a rail-mounted carrier used to move the station's robot arm from one worksite to another.

He and Behnken then moved to the outboard side of the station's power truss and removed two of six no-longer-needed handling, or "H," fixtures that were used to lift and move stowed solar arrays before launch.

All six must be removed to make way for future power system upgrades. Behnken attempted to remove the first fixture during the July 16 spacewalk, but he was unable to pull it free. Engineers then developed new procedures and this time around, the astronauts were able to pry them loose.

"Congratulations again to the H fixture team for coming up with a plan ... to get those two fixtures removed," Behnken radioed later.

Cassidy and Behnken then made their way to the left side of the power truss to prepare the outer hatch of the Tranquility module — the same compartment that features the station's multi-window cupola — for the attachment of a commercial airlock.

The Bishop Airlock, designed by Nanoracks as a commercial venture, is scheduled for launch later this year aboard a SpaceX Dragon cargo ship. Once in place, the airlock will enable research payloads and equipment to be robotically moved into and out of the space station, exposing them to the space environment as required.

The airlock will be attached to the Tranquility module's currently unoccupied outboard port. To make way for installation, Cassidy and Behnken removed a thermal cover, repositioned protective shields and cleaned the common berthing mechanism's attachment fittings.

Once the airlock preps were complete, Cassidy and Behnken wrapped up the day's work by removing a damaged lens filter from an external camera assembly and routing ethernet cables for a wireless data system that will be used by externally mounted experiments.

With the spacewalk complete, the station crew will turn its attention to the launch and docking of a Russian Progress supply ship Thursday. Liftoff from the Baikonur Cosmodrome in Kazakhstan is planned for 10:26 a.m. EDT, followed by docking that afternoon.

The next major task after that will be preparations for Behnken and Douglas Hurley to return to Earth aboard the SpaceX Crew Dragon spaceship that carried them into orbit May 30.

The Crew Dragon, developed as a commercial venture, is the first piloted U.S. orbital since the final shuttle flight in 2011. Hurley and Behnken plan to undock from the station's forward port the evening of Aug. 1 and to splash down in the Gulf of Mexico or the Atlantic Ocean off Florida's east coast on Aug. 2 to close out a 64-day flight.

Matching a Spacewalk Record

 NASA

21 июл. 2020 г.

NASA Astronauts Chris Cassidy and Robert Behnken tied the record for most U.S. Spacewalks on July 21, 2020.

It was the 10th Spacewalk for both Cassidy and Behnken tying them with former astronauts Michael Lopez-Alegria and Peggy Whitson for the most spacewalks by an American Astronaut.

Behnken and Cassidy performed a number of tasks designed to upgrade station systems. Their first task will be to install a protective unit to store tools for use by the Canadian Space Agency's Dextre robot. The storage unit also includes two Robotic External Leak Locator (RELL) units that Dextre can use to detect leaks of ammonia, which is used to operate the station's cooling system.

The astronaut duo then worked on removing two lifting fixtures at the base of station solar arrays on the near port truss, or backbone, of the station. The "H-fixtures" were used for ground processing of the solar arrays prior to their launch.

They then moved on to work to prepare the outside of the Tranquility module for the arrival later this year of the Nanoracks commercial airlock on a SpaceX cargo delivery mission.

Finally, they routed ethernet cables and removed a lens filter cover from an external camera.
