The Expedition 55 crew on board the International Space Station has been working hard to prepare for Wednesday’s spacewalk, and they’ll still have a lot of difficult work ahead of them when Flight Engineers Ricky Arnold and Drew Feustel head outside the airlock. If you’ve ever wondered what makes spacewalks such a big deal, check out chapter 17 of the new NASA ebook, The International Space Station: Operating an Outpost in the New Frontier. The book, which was written by space station flight directors, is now available to download for free at… https://go.usa.gov/xQbvH.

Chapter 17: Extravehicular Activities – Building a Space Station
Planning and Training Extravehicular Activity Tasks

On paper, the tasks needed for International Space Station assembly—e.g., driving a bolt, carrying something from one place to another, taking off a cover, plugging in an electrical cord—might not seem too complex. However, conducting such tasks while wearing a spacesuit with pressurized gloves (possibly with one’s feet planted on the end of a long robotic arm), working in microgravity, maneuvering around huge structures while moving massive objects, having time constraints based on spacesuit consumables, and using specialized equipment and tools made these tasks and EVAs challenging.

Tasks such as working with cables or fluid hoses are hand-intensive work—fingers and forearms get quite a workout in pressurized gloves that feel like stiff balloons and resemble oversized garden gloves. Added to these complexities, space “walking” is mostly done with the hands. The astronaut grasps handholds and maneuvers the combination of the Extravehicular Mobility Unity, Simplified Aid for EVA Rescue, tools, and himself or herself around the structure.

The team on the ground has to come up with a choreography and order of events for the EVA, in advance. The flight control team creates the EVA timelines based on a high-level prioritized list of tasks determined by ISS management (e.g., move a specific antenna, install a particular avionics box). The flight controllers start with the top ISS priority task and assesses the other tasks that can fit into the EVA based on multiple factors such as how long the tasks will take based on past experiences, whether both crew members need to work together, task location on the ISS, how much equipment will fit into the airlock, the tools required, crew experience level, and the level of crew effort to complete the task. A task that might fit (but only if the team is efficient) is put on the list as a “get-ahead” task.

Real-time discussions in Mission Control of EVA time remaining, crew fatigue, and suit consumables could allow the get-ahead task to be accomplished in addition to the planned tasks. Some tasks are performed on a “clock”; i.e., if power is removed from an item, it might get cold and need heater power in a matter of hours or sometimes within minutes to prevent damage. While a timeline is still in a draft version, the team conducts testing as required to prove out the operations. The team then trains the crew and refines and/or changes the timeline, sometimes up to the day of the EVA.

Two NASA astronauts are finalizing their preparations with a view ahead of Wednesday morning’s spacewalk to swap thermal control gear outside the International Space Station. The Expedition 55 crew also worked on biomedical operations, radiation checks and Cygnus communications gear.

Flight Engineers Ricky Arnold and Drew Feustel checked their tools and reviewed their procedures one last time today before tomorrow’s spacewalk. The pair will work for about 6.5 hours swapping a pair of thermal control devices, known as Pump Flow Control Subassemblies, which control the circulation of ammonia keeping external station systems cool.

The veteran spacewalkers will set their spacesuit batteries to internal power Wednesday at about 8:10 a.m. EDT signaling the official start of the 210th spacewalk in space station history. NASA TV will begin its live broadcast of the activities beginning at 6:30 a.m.

Science and maintenance are always ongoing aboard the orbital lab even despite the spacewalk and cargo mission readiness activities. Feustel and Japanese astronaut Norishige Kanai collected their biological samples this morning and stowed them in a science freezer for later analysis. Cosmonaut Oleg Artemyev explored cardiac bioelectric activity at rest. Commander Anton Shkaplerov collected radiation measurements from dosimeters he retrieved from the orbital lab’s U.S. segment.

Orbital ATK is getting its Cygnus space freighter ready for launch Sunday at 5:04 a.m. to deliver science, supplies and hardware to the Expedition 55 crew. Astronaut Scott Tingle checked out command and communications gear that will be used when Cygnus arrives four days later on Thursday for capture at 5:20 a.m.

And even earlier, we view the activity with Scott Tingle’s view of ISS in his ‘Captain’s Log’:

Week three. The time is flying by. The SpaceX Dragon cargo craft is 80% loaded. This has been a big effort for the crew as well as our specialists on the ground. Tracking a large matrix of storage locations, special requirements and loading locations is a nightmare, but our team on the ground made it look easy. Our crew is becoming more versatile and now flexes between operations and science tasking with what is seemingly just a flick of a switch. I had the opportunity to set up our Microgravity Science Glovebox for the Trans-Alloy experiment. Unfortunately, the team had to abort the science run due to high temperatures in the glovebox. Tomorrow morning, we will remove the science hardware, remove the cooling plugs, and set it all back up again. Reworks like this don’t bother me, and I am happy to do what is needed to reach success. We are on, and sometimes beyond, the frontline of science where lines between science, engineering and operations become very blurry and complex. We have to be flexible! The International Space Station (ISS) has now entered its 20th year of operations. What an engineering marvel. As with any aging program, we have accumulated an expanse of experience operating in space. As an engineering community, we are much smarter about operating in space than we were 30 years ago when we designed ISS. I will be very encouraged to see our community apply lessons learned as we create new systems to require less training, less maintenance and less logistics.

I’ve managed to take a few moments over the last week to take some pictures of Earth. Sunrises are the most beautiful part of the day. Out of total darkness, a thin blue ring begins to form that highlights the Earth’s circumference. At this moment, you can really see how thin our atmosphere is. Within a few minutes, the sun rises on station and highlights the docked vehicles while Earth just below is still in night’s shadow. A few minutes later, ISS is over brightly-lighted ground and water, providing a fresh view of the features below. The promise of a new day is real!

The crew managed to have a movie night last night, which provided some good fun and camaraderie. This was a welcome break from the busy routine we endure. Unfortunately, today, I woke to hear that astronaut and moonwalker John Young had passed away. And I also learned that a good friend from the Navy had passed away after a challenging battle with cancer. When he learned he had cancer two years ago, he decided to ignite the afterburners and live every day like there was no tomorrow…he was just as successful in his final days as he was in his previous 50 years. To two remarkable American heroes, thank you for all you have sacrificed and thank you for a lifetime of inspiration. Fair winds and following seas.

Veteran astronauts Ricky Arnold and Drew Feustel will embark on the 210th spacewalk Wednesday at the International Space Station to swap out thermal control gear. The experienced spacewalkers have a combined 10 spacewalks between them with Feustel having conducted seven and Arnold with a total of three. They will be busy.

Flight Engineer Scott Tingle assisted the duo today getting spacewalk tools ready and recharging the U.S. spacesuits inside the U.S. Quest airlock. Tingle and Japanese astronaut Norishige Kanai will assist the spacewalkers in and out of the airlock Wednesday and guide the duo during their tasks.

Orbital ATK will launch their Cygnus space freighter on Sunday at 5:04 a.m. EDT to resupply the Expedition 55 crew just four days after Feustel and Arnold complete their fourth spacewalk together. After a four-day trip in space, Cygnus will deliver crew supplies, station hardware and experiments exploring a variety of subjects including life science and space physics.

Arnold and Tingle practiced the robotics maneuvers today on a computer they will use to capture Cygnus after its approach and rendezvous with the station on May 24 at 5:20 a.m. NASA TV will broadcast the Cygnus launch and capture activities live at the orbital laboratory.

Earlier in the day the Captain’s Log:

At 22:00, after initial “safing” and unpacking of Soyuz, we finally retired to our quarters. It was very hard to sleep, and I think the busy days leading us to the International Space Station (ISS) were beginning to take their toll. We were scheduled for a full day of work to include familiarization of safety equipment as well as beginning to prepare several science experiments for action. The SpaceX Dragon cargo craft arrived to ISS a couple days before we did, and its cargo included several experiments that needed to be conducted promptly upon arrival. I was doing a great job of floating from one module to another. Since I was a little behind schedule due to having to learn where everything is, I decided I could speed up my floating to be more expeditious. Well, we know how that usually goes and this time was no exception. I gathered a “bag of knots” (aviator slang for “going really fast”) and began a healthy transition from Node 2 into the Columbus module – where I predictably hit the top of my head. Ouch. The following three days (Tuesday-Saturday) were challenging as we worked to integrate all of our new knowledge and increase our efficiencies. The senior crew was very helpful and understanding. I was very grateful of how they managed our arrival and how they slowly passed down the information we needed to get started. Everything was different from life on Earth. Everything. We quickly figured out that we needed to think differently as we began to adapt to life in space. Drinking water, preparing food, eating food, using the toilet, working, physical training, etc., all different. I had a good handle on the differences and what to expect before I got there. But I didn’t expect that when operations got very busy that my reflexes would respond naturally as they did on Earth. The light bulb came on. I was going to have to move slower and think about everything before I took action. This is why space fliers new to this environment appear to be less efficient than most managers and/or operations planners would like. Adaptation to life in space takes time, and you can’t rush it.

On day three, I finally had the opportunity to look out the Cupola (window facing Earth). My Lord, what a beautiful sight. I could see the sun rising in front of us, darkness below and behind us, and a bright blue ring highlighting the curvature of the Earth as the sun began to rise. Absolutely amazing!

We wrapped up our busy week and celebrated Saturday night by enjoying some rehydrated meats and instant juices! Christmas Eve, we had a few tasks that kept us busy, and the same on Christmas Day. Fortunately, we were able to have video conferences with our families over the holiday, and it was really nice to talk with them. We also had a very short celebration for Christmas after work was done. Our wonderful Behavioral Health Professionals at NASA had sent us Christmas stockings in the SpaceX cargo delivery. I added the small gifts that I brought for the crew – superhero socks! Mark got Hulk socks, Nemo (Norishige Kanai) got Spiderman socks, Joe got Deadpool socks, Anton got Superman socks, and Sasha and I got Batman socks. NOW, we are ready to conquer space!

Three members of the Expedition 54 crew aboard the International Space Station (ISS), including NASA astronauts Mark Vande Hei and Joe Acaba, have returned home to Earth after months of performing research and spacewalks in low-Earth orbit.

Vande Hei, Acaba and cosmonaut Alexander Misurkin of the Russian space agency Roscosmos landed at 9:31 p.m. EST (8:31 a.m. Feb. 28 in Kazakhstan) southeast of the remote town of Dzhezkazgan in Kazakhstan.

Their time on station marked the beginning of the first long-term increase in crew size on the U.S. segment, enabling NASA to double the time dedicated to research and achieve a record-setting week of research that surpassed 100 hours. Highlights from this research include investigations into the manufacturing of fiber optic filaments in microgravity, improving the accuracy of an implantable glucoses biosensor, and measuring the Sun’s energy input to Earth.

The crew also welcomed home four cargo spacecraft delivering several tons of supplies and research experiments. Orbital ATK’s Cygnus spacecraft arrived at the station in November on the company’s eighth commercial resupply mission, followed in December by SpaceX’s Dragon spacecraft on the company’s thirteenth resupply mission. Two Russian ISS Progress cargo craft arrived at the station in October and February.

Vande Hei logged 168 days in space on this, his first, mission. He ventured outside the space station on four spacewalks to perform work that included replacing and lubricating the Latching End Effectors on both ends of the Canadarm2. Acaba completed one spacewalk to lubricate an end effector and install new cameras on the station’s arm and truss. He now has accrued 306 days in space on three flights. Acaba and Vande Hei also participated in dozens of educational events while in space as part of NASA’s Year of Education on Station.

Misurkin conducted one record-setting spacewalk with fellow cosmonaut Anton Shkaplerov to replace an electronics box for a high-gain communications antenna on the Zvezda service module in February. The spacewalk timed out at 8 hours and 13 minutes, the longest in Russian space program history. Misurkin now has spent 334 days in space on two flights.

Now operating the station are Expedition 55 crew members Commander Anton Shkaplerov of Roscosmos and Flight Engineers Scott Tingle of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency. Astronauts Ricky Arnold and Drew Feustel of NASA, and Oleg Artemyev of Roscosmos are scheduled to launch March 21 and arrive at the space station two days later, returning the crew size to six.

Expedition 54 Commander Alexander Misurkin handed over control of the orbital laboratory today to fellow cosmonaut Anton Shkaplerov during a traditional Change of Command ceremony. Misurkin is returning to Earth tomorrow with NASA astronauts Joe Acaba and Mark Vande Hei after 168 days in space.

Landing day begins Tuesday when Misurkin, Acaba and Vande Hei say farewell, enter their Soyuz MS-06 spacecraft and close the hatches at 2:50 p.m. They will don their Sokol launch and entry suits, check for air and pressure leaks and undock from the Poisk module at 6:08 p.m. The Expedition 54 trio will then parachute to a landing in south central Kazakhstan at 9:31 p.m. EST (Wednesday at 8:31 a.m. Kazakh time). NASA TV will broadcast all the landing activities live starting at 2:15 p.m.

Expedition 55 officially begins when Misurkin and his crewmates undock. Shkaplerov of Roscosmos is staying behind as commander until June 3 with Flight Engineers Scott Tingle of NASA and Norishige Kanai of the Japan Aerospace Exploration Agency.

A new crew training in Russia is getting ready to replace the Earth-bound station residents in late March. Expedition 55-56 crew members Oleg Artemyev, Ricky Arnold and Drew Feustel are preparing for their March 21 launch to the station from the Baikonur Cosmodrome in Kazakhstan. They will greet their new crewmates March 23 after docking to the vacated Poisk module inside the Soyuz MS-08 spacecraft.
