Station Waits for Friday Crew Arrival Ahead of June 14 Spacewalk

Soyuz Rocket Blasts Off
The Soyuz Ms-09 rocket blasts off June 6, 2018 with three new Expedition 56-57 crew members to the space station.

Two astronauts and a cosmonaut are racing toward the International Space Station today inside the Soyuz MS-09 spacecraft. The new Expedition 56-57 trio comprising Sergey Prokopyev and Flight Engineers Serena Auñón-Chancellor and Alexander Gerst are due to arrive Friday at 9:07 a.m. EDT when they dock to the Rassvet module.

NASA TV will begin its live coverage of the rendezvous and docking of the new crew at 8:15 a.m. NASA TV will then be back on the air at 10:30 a.m. when the new crew opens the hatches at 11:05 a.m. and enters their new home in space where they will live for the next six months.

Waiting to greet their new crewmates are station Commander Drew Feustel and Flight Engineers Ricky Arnold and Oleg Artemyev who have been onboard the orbital laboratory since March. All six Expedition 56 crew members will gather in the Zvezda service module for a welcoming ceremony with family and mission officials back on Moscow. Next the crewmates will begin familiarizing themselves with station systems and safety procedures.

In the meantime, Feustel and Arnold are moving ahead with preparations for next week’s spacewalk to outfit the station’s Harmony module with new enhanced high definition television cameras and wireless communications gear. The duo organized spacewalking tools and gear, recharged spacesuit and camera batteries and reviewed procedures for the 6.5-hour excursion planned for June 14. The new cameras will improve the view of approaching commercial crew vehicles for dockings in the future. The new wireless equipment will enable data transmission from payloads mounted on the outside of the Columbus and Kibo modules.

Crew Launches to Space, Reaches Station on Friday

The Soyuz MS-09 rocket heads to space with three Expedition 56-57 crew members after launching on time from the Baikonur Cosmodrome in Kazakhstan.

The Soyuz MS-09 launched from the Baikonur Cosmodrome in Kazakhstan to the International Space Station at 7:12 a.m. EDT Wednesday, June 6 (5:12 p.m. in Baikonur). At the time of launch, the station was flying about 250 miles above south central Egypt, moving from southwest to northeast. NASA astronaut Serena Auñón-Chancellor, Alexander Gerst of ESA (European Space Agency), and Sergey Prokopyev of Roscosmos are now safely in orbit.

The crew will orbit Earth 34 times before the spacecraft’s arrival and docking to the space station’s Rassvet module at 9:07 a.m. Friday, June 8, which will air on NASA Television and the agency’s website, followed at 10:30 a.m. by coverage of the opening of hatches between the spacecraft and station.

The docking timeline Friday, June 8 EDT is:

  • 8:15 a.m. – Docking coverage begins (docking scheduled for 9:07 a.m.)
  • 10:30 a.m. – Hatch opening and welcome coverage begins (hatch opening expected at 11:05 a.m.)

 The arrival of Auñón-Chancellor, Gerst and Prokopyev will restore the station to six crew members. They will join Expedition 56 commander Drew Feustel and flight engineers Ricky Arnold of NASA and Oleg Artemyev of Roscosmos. The crew will spend more than five months conducting about 250 science investigations in fields such as biology, Earth science, human research, physical sciences and technology development.

This crew continues the long-term increase in crew size on the U.S. segment from three to four, allowing NASA to maximize time dedicated to research on the space station. Highlights of upcoming investigations include a new facility to study ultra-cold quantum gases, the first commercial European facility to conduct microgravity research, and a system that uses surface forces to accomplish liquid-liquid separation.

 Feustel, Arnold and Artemyev are scheduled to remain aboard the station until October, while Auñón-Chancellor, Gerst and Prokopyev are slated to return to Earth in December.

The Soyuz rocket that will launch three new Expedition 56-57 crew members to the International Space Station stands at its launch pad at the Baikonur Cosmodrome in Kazakhstan. Soyuz Commander Sergey Prokopyev and Flight Engineers Serena Auñón-Chancellor and Alexander Gerst are in quarantine today preparing to blast off Wednesday at 7:12 a.m. EDT on a two-day trip to the station. Live NASA TV coverage begins at 6:15 a.m.

The trio representing Roscosmos, NASA and the European Space Agency will orbit Earth for two days before arriving at the station’s Rassvet module Friday at 9:07 a.m. The crew will enter its new home after the hatches open around 11:30 a.m. to begin a six-month mission aboard the orbital laboratory. NASA TV will begin its live docking coverage Friday starting at 8:15 a.m.

Three veteran station residents will greet the newcomers Wednesday when Expedition 56 grows to its full complement of six team members. Station Commander Drew Feustel and Flight Engineers Ricky Arnold and Oleg Artemyev have been living in space since March 21 and will help familiarize their new crewmates with station systems and safety procedures.

Meanwhile, the three orbiting Expedition 56 crewmates managed to work on scientific gear and prepare for next week’s spacewalk. Feustel cleaned samples cartridges inside the Electro-Static Levitation Furnace as Arnold readied the Plant Habitat-01 for upcoming botany research. The duo also assembled and tested spacewalking gear ahead of a June 14 spacewalk to install wireless communications gear on the Harmony module.

Three crew members who have been living and working aboard the International Space Station have landed safely in Kazakhstan.

NASA astronaut Scott Tingle, Norishige Kanai of the Japan Aerospace Exploration Agency (JAXA) and Anton Shkaplerov of Roscosmos landed at 8:39 a.m. EDT (6:39 p.m. in Kazakhstan) southeast of the remote town of Dzhezkazgan in Kazakhstan.

The crew completed hundreds of experiments during their 168-day stay aboard the station. Highlights from this research include materials testing, a study of the effect of microgravity on the bone marrow, and research into plant growth in space.

The crew also welcomed four cargo spacecraft delivering several tons of supplies and research experiments A SpaceX Dragon spacecraft arrived at the station in December, followed by another Dragon in April and Orbital ATK’s Cygnus resupply spacecraft in May. A Russian Progress cargo craft arrived at the station in February.

Tingle and Kanai logged 168 days in space on their first missions. Tingle and Kanai ventured outside the station on separate spacewalks to perform work on parts of the Canadarm2 robotic arm. They also participated in dozens of educational events as part of NASA’s Year of Education on Station.

Shkaplerov conducted one record-setting spacewalk with fellow cosmonaut Alexander Misurkin to replace an electronics box for a high-gain communications antenna on the Zvezda service module. The spacewalk timed out at 8 hours and 13 minutes, the longest in Russian space program history. Shkaplerov now has spent 552 days in space on his three flights.

The Expedition 56 crew – Commander Drew Feustel and Ricky Arnold of NASA, and Oleg Artemyev of Roscosmos – will operate the station and prepare for the arrival of three new crew members on Friday, June 8. Serena Auñón-Chancellor of NASA, Alexander Gerst of ESA (European Space Agency), and Sergey Prokopyev of Roscosmos are scheduled to launch Wednesday, June 6, from Baikonur, Kazakhstan. NASA Television will broadcast the launch and docking. NASA Television will broadcast the launch and docking.

Captain’s Log – The Last Week

Expedition 55 Crew Portrait

  • Crew: Captain Scott ”Maker” Tingle, USN
  • ISS Location: Low Earth Orbit
  • Earth Date: 4 March 2018
  • Earth Time (GMT): 13:30

Wow, time has gone by extremely fast. The mid-deployment phase will be short-lived for me this time, as the new crew (Drew Feustel, Ricky Arnold, and Oleg Artemyev) will arrive on March 23rd, and then we have at least one spacewalk on the 29th, followed by a planned SpaceX Dragon cargo craft arrival on the 4th of April. It’s a little strange being up here with only two other crewmates. We are still very busy, but the overall work effort is half of what it was just a week ago. My crewmate, Nemo (Norishige Kanai), and I are trying to use the time to prepare for the upcoming very busy schedule, and we have been having some great success getting a ton of details taken care of.

I can’t believe that Expedition 55 is already over. Today is Sunday, and we will depart the International Space Station (ISS) next Sunday morning. 168 days in space. There have been many challenging moments, but even more positive highlights of our time on ISS. The new crew from the Soyuz MS-08 spacecraft (Oleg Artymyev, Drew Feustel, and Ricky Arnold) joined Norishige Kanai (Nemo), Anton Shkaplerov, and I last March. Since then, we have completed two spacewalks, captured and released the SpaceX Dragon-14 cargo craft, captured the Cygnus OA-9 cargo craft, and completed a myriad of maintenance and science activities. The team on the ground controlling, monitoring, supporting, and planning has been amazing. It is always great to work with them, and especially during the moments where the equipment, tools, procedures or crew need help. It is incredible to see how much a good team can accomplish when methodically placing one foot in front of the other. I have been lucky in that the first crew (Mark Vande Hei, Joe Acaba and Alexander Misurkin (Sasha)) and the second crew (Drew, Ricky and Oleg) were all amazing to work with. I do believe the planets aligned for my mission onboard ISS. Drew and Ricky have been friends forever, and listening to them nip at each other provided a ton of great humor for the ground and for us. Their one-liners to each other reminded me of several scenes from the movie Space Cowboys. This a great example that happened as I was writing this log entry:

Ricky:  Hey Maker, is this your smoothie?
Maker:  No.
Ricky:  It must Drew’s.
Drew:  Hey Ricky, don’t drink my smoothie.
Ricky:  What smoothie? This one has my name on it (as he writes his name on it).
Drew:  Okay, Grandpa Underpants, hands off my smoothie.
Ricky:  Okay, Feustelnaut – we have rules around here, so this is my smoothie now!
All:  Much laughing.

To quote my kids: “LOL!”

One the hardest things to do in space is to maintain positive control of individual items such as tools, spare parts, fasteners, etc. We try very hard not to lose things, but even with all of the attention and positive control, items can still float away and disappear. We generally hold items in a crew transfer bag (CTB).  Inside the CTB are many items for the system that it supports. When the CTB is opened, the items are free floating inside the bag and tend to escape. It is very difficult to maintain control of the items – especially if they are small, do not have Velcro, or when the daily schedule is so tight that we are rushing to stay on time.   We always try to close the CTB’s and Ziploc bags after removing or replacing each item to maintain positive control, but this takes much more time to do for individual items, and if the timeline is tight, we absorb more risk by rushing. The same applies for tools, which we usually keep in a Ziploc bag while working on individual systems and tasks. Last month, I was installing a new low temperature cooling loop pump that had failed a month or two earlier. I gathered the needed tools into my modified (with Velcro) Ziploc bag as I always do and floated over to the work area. When I got there, one of the tools that I had gathered was missing. I looked for 30 minutes, and could not find it. Lost items are very hard to find because the items that escape are usually barely moving and blend in with the environment very quickly. A lost item could be right in front of us and we would never see it. Our crew, after learning these lessons, decided that when anyone loses something, we would tell the other crew members what we had lost with a general location. This has had a huge impact on finding items. If a different crew member can help within the first minutes of losing an item, the new crew member has an excellent chance of finding the item. We have proven this technique several times during the expedition – and Nemo was the very best at quickly finding lost items.  But, in my case, we still could not find the missing tool. Our amazing ground team understood and vectored me to a replacement tool and I finished the job. I spent the next 3 weeks watching, looking, and never forgetting about the lost tool. Then, one day last week, Oleg came to the lab and handed us a tool he had found in his Soyuz spacecraft, way on the aft side of the ISS. Amazing. We finally found the tool and I was happy again. This was a lucky ending. ISS has many corners, crevices and hard-to-see areas where missing items could hide and never be found.

We captured a Cygnus cargo craft last Thursday. I was very impressed with the entire team. Our specialists and training professionals in Mission Control did a great job preparing the necessary procedures and making sure we were proficient and ready to conduct operations. The robotic arm is a wonderful system that we could not operate ISS without. Being in space, however, it has some very unique handling qualities. If you think about a spring-mass-damper system just as you did during physics or control theory class, and then remove the damper, you will see a system that is very subject to slow rate oscillations.  In test pilot terms, damping ratio is very low and the latency is well over a half of a second. Also in test pilot terms – this is a pilot-induced oscillations (PIO) generator. These characteristics require crew to “fly” the robotic arm using open-loop techniques, which requires a huge amount of patience. Test pilots are sometimes not very patient, but understanding the system and practicing with the incredible simulators that our ground team built and maintain help keep our proficiency as high as possible. The capture went flawlessly, and I was very impressed with the professionalism across the board – crew, flight controllers, and training professionals – what a great job!

Drew, Ricky and I got to play guitar a few times while on ISS. This was fun! Drew connected pickups to the acoustic guitars and then connected the pickups to our tablets for amplification. I’ve never heard an acoustic guitar sound like an electric guitar amped up for heavy metal before. We had a great jam on the song “Gloria”, and a couple others. Rock on!

Last night we had our last movie night. The entire crew gathered in Node 2 and watched Avengers Infinity Wars on the big screen. We enjoy each other’s company, as we did during Expedition 54, and this was a welcome break from the daily grind of trying to complete the required stowage, maintenance and science activities while preparing for departure.

Our last full weekend here on ISS. I gave myself a haircut. We usually clean our spaces each weekend to make sure we can maintain a decent level of organization, efficiency and morale. This weekend is no different, and it is time for me to vacuum out all of our filters and vents. You’d be amazed at what we find!

The top 5 things I will miss when I am no longer in space:

  1. The incredible team that supports ISS operations from our control centers
  2. The camaraderie onboard ISS
  3. The breathtaking view of the Earth, Moon, Sun and Stars
  4. Floating/flying from location to location with very little effort
  5. Operations in the extreme environment of space

Crew Juggles Science, Departure Preps and Spacewalk Work

The coast of Western Australia
The city of Perth, Garden Island and Rottnest Island are pictured as the International Space Station began an orbital pass across the coast of Western Australia.

 

International Space Station Commander Anton Shkaplerov will lead fellow Expedition 54-55 crewmates Scott Tingle and Norishige Kanai back to Earth early Sunday morning. The trio will undock from the Rassvet module inside the Soyuz MS-07 spacecraft on Sunday at 5:16 a.m. Just three and a half hours later the homebound crew will parachute to a landing in Kazakhstan after 168 days in space. NASA TV will broadcast live the undocking and landing activities.

Three more crew members are waiting in Kazakhstan to replace the Expedition 54-55 crew. Soyuz MS-09 Commander Sergey Prokopyev will launch with Expedition 56-57 Flight Engineers Serena Auñón-Chancellor and Alexander Gerst on June 6 from Kazakhstan on a two-day ride to their new home in space.

The following week after the crew swap activities, NASA astronauts Ricky Arnold and Drew Feustel will go out on their third spacewalk together this year. The duo will install new high definition cameras and route cables on the Harmony module during the 6.5-hour spacewalk planned for June 14. Tingle is readying some of the gear today that will be installed during that spacewalk.

Finally, Feustel and Arnold spent a little over half their day today setting up the new Cold Atom Lab (CAL). The duo installed the scientific gear in the Destiny lab module, connected cables and inspected fiber optics before powering up the low temperature research device. The CAL will chill atoms to temperatures barely above absolute zero allowing scientists to observe quantum behaviors not possible on Earth.

Crew Unloading Cygnus While New Trio Preps for Launch

From left are Expedition 56-57 crew members Alexander Gerst, Sergei Prokopyev and Serena Auñón-Chancellor with back up crew members Anne McClain, Oleg Kononenko and David Saint-Jacques.

The Expedition 55 crew is unloading the Orbital ATK Cygnus space freighter today ahead of next week’s crew swap at the International Space Station. On top of the cargo transfers and crew departure activities, the orbital residents are also running space experiments to benefit humans on Earth and astronauts in space.

NASA Flight Engineer Scott Tingle has been working inside Cygnus today unpacking station hardware and research gear delivered just last week. He removed science kits and spacewalking gear and stowed them throughout the orbital lab.

Tingle finally wrapped up his workday with his homebound crewmates Commander Anton Shkaplerov and Flight Engineer Norishige Kanai preparing for their June 3 return to Earth. The trio packed personal items and other gear inside the Soyuz MS-07 spacecraft that will parachute the crew to a landing in Kazakhstan after 168 days in space.

Back on Earth, Soyuz MS-09 Commander Sergey Prokopyev and Flight Engineers Serena Auñón-Chancellor and Alexander Gerst are in final training in Kazakhstan ahead of their June 6 launch to the space station. The Expedition 56-57 trio will orbit Earth for two days before docking to the Rassvet module to begin a six-month stay in space.

NASA astronauts Ricky Arnold and Drew Feustel, who are staying in space until Oct. 4, familiarized themselves today with the new Cold Atom Lab’s hardware and installation procedures. The device, delivered last week on Cygnus, will research what happens to atoms exposed to temperatures less than a billionth of a degree above absolute zero.

The two later split up as Arnold set up thermal hardware that will help scientists understand the processes involved in semiconductor crystal growth. Feustel moved on and began uninstalling a plant biology facility, the European Modular Cultivation System (EMCS), which has finalized its research operations. The EMCS will now be readied for return to Earth aboard the next SpaceX Dragon cargo craft.
