  • 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

Astronaut Commands Robotic Arm to Capture Cygnus Cargo Craft

Cygnus Captured
The Cygnus space freighter is grappled by the Canadarm2 after a three-day trip to the space station.

At 5:26 a.m. EDT, Expedition 55 Flight Engineer Scott Tingle of NASA successfully captured Orbital ATK’s Cygnus cargo spacecraft using the International Space Station’s robotic arm, backed by NASA Astronauts Ricky Arnold and Drew Feustel. Robotic ground controllers will position Cygnus for installation to the orbiting laboratory’s Earth-facing port of the Unity module.

NASA TV coverage of operations to install the Cygnus, dubbed the S.S. James “J.R.” Thompson, to the space station’s Unity module will resume at 7:30 a.m.

The Cygnus space freighter from Orbital ATK is closing in on the International Space Station ready to deliver 7,400 pounds of cargo Thursday morning. The Expedition 55 crew members are getting ready for Cygnus’ arrival while also helping researchers understand what living in space does to the human body.

NASA TV is set to begin its live coverage of Cygnus’ arrival at the orbital lab Thursday at 3:45 a.m. EDT. Flight Engineer Scott Tingle will be inside the Cupola and command the Canadarm2 robotic arm to reach out and capture Cygnus at 5:20 a.m. Robotics engineers at Mission Control will then take over and remotely install Cygnus to the Earth-facing port of the Unity module later Thursday morning.

The crew started its day collecting blood and urine samples for a pair of experiments, Biochemical Profile and Repository, looking at the physiological changes taking place in astronauts. Those samples are stowed in science freezers for return to Earth so scientists can later analyze the proteins and chemicals for indicators of crew health.

Another pair of experiments taking place today is looking at bone marrow, blood cells and the cardiovascular system. The Marrow study, which looks at white and red blood cells in bone marrow, may benefit astronaut health as well as people on Earth with reduced mobility or aging conditions. The Vascular Echo experiment is observing stiffening arteries in astronauts that resembles accelerated aging.

Engineers at the Institute of Robotics and Mechatronics in Germany set up the robot called Justin in a simulated Martian environment. Justin was given a simulated task to carry out, with as few instructions as necessary. The maintenance of solar panels was the chosen task, since they’re common on landers and rovers, and since Mars can get kind of dusty.

Yesterday I had a funny event, though. I was controlling a robot named “Justin” who was located in Munich. The research and demonstration events were so interesting and fun that I offered them my lunch hour to do an additional protocol and have a longer debrief session. The ground team responded happily and accepted the offer – any extra time with crew onboard the International Space Station (ISS) is valuable to our programs. Halfway through the event, the team needed a few minutes to shut down and restart the robot, and I surmised that since I was skipping my break, this would be a good time to use the toilet. And I did, use the toilet. And literally 3 minutes later I returned, waited another 2 minutes for the robot systems to connect, and we began another great session controlling Justin from ISS with no loss to science. Later that same day, I was approached by the ground team in Houston (not the test team I was working with in Munich) and queried if something was wrong, and why did I have to take a toilet break while we were executing valuable science? They were concerned that I might have a medical issue, as taking a break in the middle of some very valuable science is not normal for us to do while on ISS. It’s nice to know that we have literally hundreds of highly-trained professionals looking out for us.

 

Captain’s Log – Unusual Attitude Recovery

While flying fast-moving jets, we practice the art of recovering from unusual attitudes. We close our eyes, and let the instructor put the jet in an unexpected attitude. Sometimes straight up, sometimes straight down, sometimes upside down, and sometimes anything in-between. The goal is to open our eyes, analyze the situation and make rapid and smooth corrections to power and attitude to effect a speedy recovery to straight and level flight without departing controlled flight, or having to endure high G’s, or experiencing big losses of altitude. Sometimes, when I crawl into my crew quarters on the space station, it is very dark – just like closing our eyes in the jet. And then, as I sleep, my body floats around and changes position. When I awake in total darkness, I have to figure out what attitude I am in relative to my crew quarters and then right myself.  “Unusual Attitude Recovery” can be pretty funny. And sometimes, my heart can get pumping as I awake and realize I don’t know what my attitude is. I execute my procedures to figure out what my attitude is, and then correct it. At first, it used to take me a while to realize. But now, it is second nature – and it always brings a smile to my face.

 

Station Crew Juggles Science, Cargo Mission and Spacewalk Preps

Astronaut Drew Feustel

The Expedition 55 crew members had a full complement of work today as they conducted microgravity research, trained to capture a resupply ship and prepared for a June spacewalk.

Astronaut Norishige Kanai explored how living and working in space affects everything from fluid physics to the human body today. He first set up hardware to visualize how water atomizes in microgravity possibly improving the production of spray combustion engines. Next, he researched how spaceflight is impacting his brain structure and function, motor control, and multi-tasking abilities.

Later he joined fellow Flight Engineers Scott Tingle and Ricky Arnold to practice the robotics techniques necessary to capture the Orbital ATK Cygnus resupply ship. The trio trained on a computer to simulate the operation of the Canadarm2 when it reaches out and grapples Cygnus on Thursday.

The commercial space freighter is due to deliver over 7,400 pounds of crew supplies, station hardware and science experiments when it arrives Thursday at 5:20 a.m. EDT. NASA TV will broadcast live the approach, rendezvous and capture of Cygnus beginning at 3:45 a.m.

NASA Flight Engineer Drew Feustel worked on U.S. spacesuits today ahead of the next spacewalk planned for June 14. He scrubbed the spacesuit cooling loops, collected water samples and organized tools in the Quest airlock.

The veteran spacewalker has a total of eight spacewalks having worked in the vacuum of space for nearly 55 hours. He will partner with Arnold, who has four spacewalks for over 25 hours, June 14 to install high definition cameras on the Harmony module.

The cargo ship will rendezvous with the International Space Station on Thursday, May 24. Expedition 55 Flight Engineer Scott Tingle will grapple the spacecraft at approximately 5:20 a.m. EDT, backed by Ricky Arnold, and Drew Feustel will monitor Cygnus systems during its approach. They will use the space station’s robotic Canadarm2 to take hold of the Cygnus, dubbed the S.S. James “J.R.” Thompson. After Cygnus’ capture, ground controllers will command the robotic arm to rotate and install Cygnus onto the station’s Unity module. It is scheduled depart the space station in mid-July.

Live coverage of the rendezvous and capture will air on NASA Television and the agency’s website beginning at 3:45 a.m. Thursday, May 24. Installation coverage is set to begin at 7:30 a.m.

Science investigations aboard Cygnus on their way to the space station also include commercial and academic payloads in myriad disciplines, including:

  • The Biomolecule Extraction and Sequencing Technology (BEST), an investigation to identify unknown microbial organisms on the space station and understand how humans, plants and microbes adapt to living on the station
  • The Cold Atom Laboratory, a physics research facility used by scientists to explore how atoms interact when they have almost no motion due to extreme cold temperatures
  • A unique liquid separation system from Zaiput Flow Technologies that relies on surface forces, rather than gravity, to extract one liquid from another
  • The Ice Cubes Facility, the first commercial European opportunity to conduct research in space, made possible through an agreement with ESA (European Space Agency) and Space Applications Services.
  • The Microgravity Investigation of Cement Solidification (MICS) experiment is to investigate and understand the complex process of cement solidification in microgravity with the intent of improving Earth-based cement and concrete processing and as the first steps toward making and using concrete on extraterrestrial bodies.
  • Three Earth science CubeSats
    • RainCube (Radar in a CubeSat) will be NASA’s first active sensing instrument on a CubeSat that could enable future rainfall profiling missions on low-cost, quick-turnaround platforms.
    • TEMPEST-D (Temporal Experiment for Storms and Tropical Systems Demonstration) is mission to validate technology that could improve our understanding of cloud processes.
    • CubeRRT (CubeSat Radiometer Radio Frequency Interference Technology) will seek to demonstrate a new technology that can identify and filter radio frequency interference, which is a growing problem that negatively affects the data quality collected by radiometers, instruments used in space for critical weather data and climate studies.

I did an interview with some students today, and I was asked a two-part question by one of the students. He asked, “What is the most exciting thing about being in space, and how did you keep yourself motivated to get there?”

I answered, “When you were very young, did you ever dream or wish you could fly? We all know it’s impossible, right? Imagine waking up one day and finding out you actually can fly! THAT is exciting! Now consider the contrary thought, what if you grew up and realized that flying wasn’t possible for humans, and you were at peace with this reality, and at peace shedding your childhood dream of flying? You will have several crossroads in your life, and you will have to decide which of these people you want to be. I too am amazed that I had the staying power to continue to dream as I did when I was a child. Words cannot describe how I feel when I fly through the International Space Station every day.”

 

Captain’s Log – Alarms

The smoke detectors have been setting off alarms. This happens routinely due to dust circulating in the modules, but every alarm is taken seriously. This is the third time that the alarm has sounded while I was using the Waste & Hygiene Compartment (toilet). I am starting to think that my actions are causing the alarms…. maybe I should change my diet?

We just finished a 20-hour work day. I spent nearly 11 hours in the spacesuit, and 7 hours and 24 minutes doing a spacewalk. The view was amazing. The changes from day to night, and back to day were phenomenal. My fellow astronaut Mark Vande Hei and I completed the primary task of replacing the Latching End Effector, or hand, for the robotic arm, but a software glitch kept us waiting and we were unable to complete any get-ahead tasks. I thought we had plenty of time and estimated that we had only been outside for a few hours. I was very surprised to find that we had worked for over 7 hours. Wow, I guess time really does fly by when you are having fun!
