Expedition 50 Commander Shane Kimbrough and Flight Engineer Peggy Whitson of NASA concluded their spacewalk at 2:33 p.m. EDT. During the spacewalk, which lasted just over seven hours, the two astronauts successfully reconnected cables and electrical connections on the Pressurized Mating Adapter-3. PMA-3 will provide the pressurized interface between the station and the second of two international docking adapters to be delivered to the complex to support the dockings of U.S. commercial crew spacecraft in the future.

The duo were also tasked with installing four thermal protection shields on the Tranquility module of the International Space Station. The shields were required to cover the port where the PMA-3 was removed earlier in the week and robotically installed on the Harmony module. During the spacewalk, one of the shields was inadvertently lost. The loss posed no immediate danger to the astronauts and Kimbrough and Whitson went on to successfully install the remaining shields on the common berthing mechanism port.

A team from the Mission Control Center at NASA's Johnson Space Center in Houston devised a plan for the astronauts to finish covering the port with the PMA-3 cover Whitson removed earlier in the day. The plan worked, and the cover was successfully installed, providing thermal protection and micrometeoroid and orbital debris cover for the port.

To round out the spacewalk, Kimbrough and Whitson also installed a different shield around the base of the PMA-3 adapter for micrometeoroid protection. The shield was nicknamed a cummerbund as it fits around the adapter similar to a tuxedo's cummerbund worn around the waist.

Having completed her eighth spacewalk, Whitson now holds the record for the most spacewalks and accumulated time spacewalking by a female astronaut.

Spacewalkers have now spent a total of 1,243 hours and 42 minutes outside the station during 199 spacewalks in support of assembly and maintenance of the orbiting laboratory.

Shane Kimbrough and Peggy Whitson, setting a new record as the world's most experienced female spacewalker, floated outside the International Space Station Thursday and continued work to set up a second docking port for U.S. crew ferry ships. They also installed an upgraded computer relay box and protective shielding before calling it a day.

One of the shield segments being installed on a vacant port managed to escape its tether, floating away before the astronauts noticed.

"Peggy, I don't have a shield," Kimbrough radioed, surprised.

"What?"

"Yeah, I don't have a shield," he repeated.

"Where is it?" Whitson asked. "Ah, it is right by the radiator. It is moving station zenith, maybe half a foot a second and it's going, looks like straight zenith fr om the radiator angle."

The micrometeoroid shield was one of four being installed on the Tranquility module's outboard port. Flight controllers quickly determined it posed no threat of recontacting the station and after conferring on the ground, engineers suggested the astronauts make up for the lost panel by installing a thermal shield they had just removed fr om a docking port extension.

They did that, and completed the rest of their objectives before returning to the station's Quest airlock, repressurizing the compartment and ending the seven-hour four-minute spacewalk at 2:33 p.m. EDT (GMT-5)

"Thank you guys, you did an amazing job, you had to deal with, obviously, the issue early on and came up with a great plan," Kimbrough radioed flight controllers. "We really enjoyed working with you guys, it was an honor to be part of the team. Thanks to everybody."

"Shane, thank you for the words," astronaut Anne McClain replied from mission control at the Johnson Space Center. "We certainly appreciate the work you both have done over the last couple of hours and your problem solving skills to get the mission accomplished."

Floating in the Quest airlock, Kimbrough and Whitson switched their spacesuits to battery power at 7:29 a.m. to officially kick off U.S. EVA-41, the second NASA spacewalk in one week.

This was the 199th EVA in station history, the fourth so far this year, the sixth for Kimbrough and the eighth for Whitson.

Four hours and 22 minutes into the excursion, Whitson, a veteran of two earlier long-duration station visits, set a new record for cumulative spacewalk time by a female astronaut, surpassing Sunita Williams' mark of 50 hours and 40 minutes. When the spacewalk concluded, Whitson's total EVA time stood at 53 hours and 22 minutes, moving her up to fifth on the list of most experienced spacewalkers.

NASA is in the process of setting up a second docking port on the station to accommodate visits by commercial crew ferry ships being built by Boeing and SpaceX. One port already is in place on the front of the station's forward Harmony module.

Last week, during during a spacewalk by Kimbrough and European Space Agency astronaut Thomas Pesquet, cables connecting a docking port extension on the outboard port of the Tranquility module were disconnected.

Over the weekend, flight controllers at the Johnson Space Center used the station's robot arm to move the extension, known as pressurized mating adapter No. 3, or PMA-3, from Tranquility to the upper port of Harmony. A docking mechanism will be attached to the outboard end of the tunnel late this year or early next.

During today's spacewalk, Whitson hooked up heater cables and remove a thermal cover from PMA-3 while Kimbrough installed an upgraded computer relay box in the station's power truss.

Both spacewalkers then worked to install four protective shields over Tranquility's outboard port wh ere PMA-3 had been attached. It was during that work that Kimbrough noticed one of the folded panels had escaped.

The spacewalkers then retrieved the thermal shield Whitson had removed from PMA-3 earlier and used cables and clamps to hold it in place over the Tranquility port, filling in the gap left by the lost panel.

Once that work was done, the astronauts returned to PMA-3 and installed a different set of shields around the base of the extension wh ere it connects with Harmony's upper port.

Whitson and Pesquet are officially scheduled to carry out another spacewalk April 6, but needed equipment is awaiting launch aboard an Orbital ATK Cygnus cargo ship that has been grounded by work to repair hydraulic lines in the freighter's Atlas 5 rocket.

In the meantime, Kimbrough, Soyuz MS-02 commander Sergey Ryzhikov and flight engineer Andrey Borisenko are scheduled to return to Earth on April 10, landing on the steppe of Kazakhstan to close out a 173-day mission. The next spacewalk is not expected until after two fresh crew members — Soyuz MS-04 commander Fyodor Yurchikhin and flight engineer Jack Fischer — arrive on April 20.

But whenever the next spacewalk takes place, Whitson is expected to move up to No. 3 on the list of world's most experienced spacewalkers with a total time of about 59 hours over nine EVAs. Only cosmonaut Anatoly Solovyev and former astronaut Mike Lopez-Alegria have more time outside, with 68 and 67 hours of EVA time respectively.

240 miles above Earth, traveling 12 times the speed of a bullet, a cloth blanket gets away during a spacewalk and immediately drifts out of reach, into space, away from the space station, forever. It's no danger to the astronauts as it floats away, but immediately there is a new problem:

An important station docking port needs that blanket for protection from the extremes of space, and now it is gone.

That's when you call Houston, or more likely Houston calls you first, and Mission Control finds an answer.

Спойлер

"This was the kind of thing we train for," said Mission Control Flight Director Emily Nelson "Most of the time we get issues like this to work inside the station. We have a multi-layered team that comes together to solve problems. This is probably the most visible version of this we've had in a long time, but we solve problems large and small with some frequency. It's part of operating a complex orbiting space station."

• Mission controllers celebrate Apollo 11 -- the first moon landing
  

Nelson oversaw the work to come up with a solution for protecting the docking port and its critical seal with a used cover during the March 30 spacewalk. The used cover had been removed earlier in the spacewalk from another piece of station equipment, and it wasn't designed to fit in place of the lost blanket.

"People ask me who came up with the idea to use that cover," she said. "Honestly, all the people in the building watched the crew wrestle with that cover (the one eventually used to substitute for the lost shield) earlier in the day, so it occurred to everybody almost simultaneously that 'Hey, we've got a cover that's roughly the right size and we just stuck that in the airlock, so maybe we could use it?'"

"That's true," said John Mularski, the lead EVA, or spacewalk, officer. "Everybody watching the video had the exact same idea, but then somebody had to implement the details of it."

"Using the cover was pretty obvious, but knowing we were going to be able to find a way to securely tether it so that we wouldn't constrain any further ISS operations -- that part was not at all obvious," Nelson said.

As has been the case many times past in both famous and everyday instances, Mission Control faced the challenge of not only fitting a square peg into a round hole, but also doing it on deadline and making it work as if the two were made to go together.

"Anne McClain, our spacewalk communicator astronaut, and Steve Bowen, an experienced spacewalker who was working as our spacecraft communicator for the day, sanity checked how we were going to do that," Nelson said. "Anne did a phenomenal job of reading the concept to the crew. The crew then did a phenomenal job understanding and visualizing what we really wanted.

"The crew was doing it in the dark so that made it more complicated. We had a great camera view of the big picture but had no light. When the sun came up, we used the robotic arm camera to see we were in a good configuration."

"From the moment we realized the shield had escaped to the time we had it fixed was about 2 hours and 20 minutes," Mularski added.

"The unique aspect of this problem was the need for our greater team to work incredibly quickly," Nelson explained. "It was designers, analysts and engineers who work behind the scenes, working with operations engineers, flight controllers, and crew members."

"Everyone on the broader team comes from a different perspective. We all have our different expertise. But the team works together to make sure we're doing the right things, and at the end of the day we need to make sure we're making the situation better and not in some way making it worse," added Daren Welsh, the EVA flight controller who was responsible for working with engineering teams to develop the technical details of the solution and creating a plan the team could execute.

NASA is planning a daring repair mission to save a $2 billion particle detector  
The Alpha Magnetic Spectrometer "is changing our understanding of the cosmos."
 Eric Berger - 4/3/2017, 4:40 PM
 
The Alpha Magnetic Spectrometer has served during the last six years as a silent witness to the formation of the universe, quietly collecting about 100 billion cosmic rays, particles, and nuclei with energies up to 1 trillion electron volts. "The results show unexpected phenomena—they are not predicted by current cosmic ray models—and this is changing our understanding of the cosmos," principal investigator Sam Ting told Ars.
But as this publication recently reported, there is a problem with the AMS particle detector's cooling system, and NASA is planning an extensive set of repairs. This will likely include a series of "Hubble-esque" spacewalks in 2018 to install a new cooling system for the $2 billion instrument. After the initial story, Ting provided Ars with more information about the scope and timing of the repairs.
According to Ting, there are four redundant pumps in the cooling system that keep AMS' silicon tracker at a constant 10 degrees Celsius, plus or minus three degrees. The system was originally designed to last three years in space, but now after almost six years two of the four pumps have stopped functioning. The experiment is using the third pump, which is operating normally. The fourth pump has shown signs of malfunctioning and is therefore kept in reserve.
Given that the rest of the experiment is continuing to function beyond its design lifetime, both the AMS scientists and NASA would like to see the experiment continue and are preparing to fix a machine that wasn't designed with on-orbit servicing in mind. The repairs will therefore involve several tricky spacewalks, for which NASA has had teams of astronauts, engineers, and flight directors training for more than a year. Ting explained that the repair plans are still not final, but are coming into shape.
"Together with the NASA Johnson Space Center, we have improved the pump design to extend the lifetime of AMS to coincide with the lifetime of the ISS," he said. "Twelve new pumps have been ordered and will be delivered in September of this year. After extensive tests, four of the new pumps are scheduled to be sent to the space station in the later part of 2018 as replacements."
Despite the cost (one person involved in the planning said that under some scenario, the repairs could cost as much as $100 million), researchers say the additional time collecting data is critical to the experiment's success. "By collecting data until at least 2024, we should be able to make a statement on the origin of dark matter and antimatter," Ting said. "So far, all other the instruments are operating normally and we expect to stay operational on the space station for its lifetime."

ЦПК. ЗАСЕДАНИЕ МВК И ПРЕСС-КОНФЕРЕНЦИЯ ОСНОВНОГО И ДУБЛИРУЮЩЕГО ЭКИПАЖЕЙ МКС 51/52

В Центре подготовки космонавтов имени Ю.А.Гагарина состоялось заседание Межведомственной комиссии, которая, рассмотрев результаты подготовки основного и дублирующего экипажей длительной экспедиции МКС 51/52 к космическому полету, рекомендовала их для продолжения предстартовой подготовки на космодроме БАЙКОНУР.   

В состав основного экипажа вошли летчик-космонавт, Герой Российской Федерации Фёдор ЮРЧИХИН, для которого этот полет станет пятым в карьере, и астронавт NASA Джек ФИШЕР, который побывает в космосе впервые. Дублерами являются летчик-космонавт, Герой Российской Федерации Сергей РЯЗАНСКИЙ и астронавт NASA Рэндолф БРЕЗНИК.   

В ходе пресс-конференции, которая состоялась после заседания Межведомственной комиссии, основной и дублирующий экипажи ответили представителям средств массовой информации на интересующие их вопросы.   

«Мы будем усердно работать на станции, когда останемся на ней вдвоем, и приложим все усилия, чтобы выполнить и полностью реализовать научную программу», - сказал бортинженер транспортного пилотируемого корабля «Союз МС-04» Джек ФИШЕР, отвечая на вопрос журналистов о работе на борту МКС в сокращенном составе.   

«Если раньше работу на Международной космической станции выполняли трое человек, то сейчас нам придется передвигаться быстрее и делать это вдвоем. Я думаю, что чувство плеча будет нам помогать. Ну и будем перемещаться быстрее», - рассказал Федор ЮРЧИХИН.   

«Мы можем добиться успеха только когда работаем вместе», - поддержал командира корабля «Союз МС-04» Фёдора ЮРЧИХИНА Джек ФИШЕР.   

Талисманом и индикатором невесомости экипажа станет плюшевый щенок: «Он никогда меня не покидал и готовится к своему уже пятому полету. Он стойко переносит все трудности: покоряет со мной горные вершины, летает в космос, погружается под воду», - рассказал российский космонавт Фёдор ЮРЧИХИН.   

Вторым талисманом станет игрушечное цветное Солнце - символ больницы, в которой от рака вылечили дочь астронавта NASA Джека Фишера.   

После завершения пресс-конференции основной и дублирующий экипажи, согласно многолетней традиции, посетили кабинет Юрия ГАГАРИНА, точно воспроизведённый в музее ЦПК. И оставили запись в памятной книге. Затем экипажи посетили Красную площадь, где почтили память Сергей Королёва и захороненных в Кремлёвской стене космонавтов.   

Старт ракеты-носителя «Союз-ФГ» с пилотируемым кораблем «Союз МС-04» запланирован на 20 апреля. Планируемая продолжительность экспедиции составляет 136 суток.

Американские мыши не полетят в космос с новой экспедицией на МКС
ЗВЕЗДНЫЙ ГОРОДОК /Московская область/, 3 апреля. / ТАСС/. Мыши не войдут в "экипаж" очередной экспедиции на МКС, сообщил на пресс-конференции в Центре подготовки космонавтов россиянин Федор Юрчихин. На этот раз на МКС полетят два человека вместо привычных трех. Место третьего члена экспедиции займет полезный груз.
"Мышей там точно не будет. Вес контейнера порядка 70 кг. Определены вещи, которые могут компактно улечься в контейнер: влажные салфетки, продукты питания, - рассказал космонавт. - Нужно заполнить контейнер таким образом, чтобы он не мешал нам работать с органами управления аппарата". Также он добавил, что точный перечень грузов станет понятен на первой "примерке" космического корабля 6 апреля.
Юрчихин пояснил, что NASA и Роскосмос ранее вели предварительные переговоры об отправке вместе с пилотируемой экспедицией на корабле "Союз" американских мышей для проведения совместного эксперимента на борту МКС.
Старт ракеты-носителя "Союз-ФГ" с пилотируемым кораблем "Союз МС-04" с очередной экспедицией намечен на 20 апреля на 10:13 мск. В тот же день ориентировочно в 16:22 мск ожидается стыковка с модулем "Поиск" российского сегмента станции. Планируемая продолжительность экспедиции составляет 136 суток.
