The seven-member Expedition 65 crew kicked off the workweek working on Japanese science gear, a U.S. immune system study, and spacewalk preparations.

Flight Engineers Mark Vande Hei and Thomas Pesquet joined station Commander Akihiko Hoshide for science maintenance in the Kibo laboratory module on Monday morning. The trio teamed up and installed an experiment platform in Kibo’s airlock, where it will soon be placed outside in the harsh environment of space.

Vande Hei then moved on and serviced donor cell samples for the Celestial Immunity study taking place inside the Kibo lab’s Life Sciences Glovebox (LSG). The experiment looks at cells launched to space and compares them to cell samples harvested on Earth to document the differences in weightlessness. Results could impact the development of new vaccines and drugs to treat diseases on Earth and advance the commercialization of space.

Pesquet later took photographs of U.S. spacesuit gloves for inspection ahead of two spacewalks planned for June. During those spacewalks, new solar arrays will be installed on the station’s Port 6 truss structure to augment the station’s power system. The first two of six new solar arrays will be delivered on the next SpaceX cargo mission planned for launch on June 3 from NASA’s Kennedy Space Center.

Hoshide checked power cables on the Confocal Space Microscope that provides fluorescence imagery of biological samples. Then he took turns with NASA Flight Engineer Shane Kimbrough, participating in a computerized cognitive assessment. Next, Kimbrough worked the rest of Monday in the Tranquility module’s Water Processing Assembly to repair a possible leak.

NASA Flight Engineer Megan McArthur opened up BEAM, or the Bigelow Expandable Activity Module, and organized cargo during the morning. She then powered down and stowed the LSG after Vande Hei concluded Monday’s immunity research.

Cosmonauts Oleg Novitskiy and Pyotr Dubrov spent the morning organizing Russian spacewalk tools. Afterward, the duo spent the rest of the day working on communications gear and ventilation systems.

Tuesday’s science aboard the International Space Station encompassed life science, fluids and flames to help humans on Earth and in space. The Expedition 63 crew also configured spacewalk tools and opened up an expandable module.

Commander Chris Cassidy of NASA collected and stowed his blood and urine samples today for later analysis. He also set up an experiment that observes how fluids flow in micrometer-sized tubes to improve medical diagnostic devices on Earth and in spaceships.

Cassidy also joined NASA Flight Engineer Bob Behnken organizing and inspecting a variety of gear ahead of two spacewalks planned for June 26 and July 1. The duo will be swapping old nickel-hydrogen batteries with new lithium-ion batteries on the Starboard-6 truss structure to upgrade the station’s power systems.

Behnken opened up and entered BEAM, the Bigelow Expandable Activity Module, to retrieve life support equipment during the afternoon. He also partnered up with fellow Flight Engineer Doug Hurley unpacking new science equipment from Japan’s H-II Transfer Vehicle-9 (HTV-9) resupply ship and installing it in Europe’s Columbus laboratory module.

Veteran cosmonaut Anatoly Ivanishin continued to service the Combustion Integrated Rack replacing fuel bottles to maintain safe fuel and flame research in the device. Insights could improve fire safety as well as combustion processes for Earth and space industries. His Russian colleague Ivan Vagner worked on a pair of Earth observation studies monitoring the effects of catastrophes and the development of forests.

Ever wanted a deeper dive into the life of the International Space Station? The flight directors in charge of the teams that oversee its systems have written a 400-page book that offers an inside look at the time and energy the flight control team at the Mission Control Center at NASA’s Johnson Space Center in Houston devote to the development, planning and integration of a mission.

Here’s an excerpt from the book to give you a taste of what to expect:

Chapter 10: Preparing for the Unexpected

At 2:49 a.m. Central Standard Time, a red alarm illuminated the giant front wall display in Mission Control in Houston. The alert read: TOXIC ATMOSPHERE Node 2 LTL IFHX NH3 Leak Detected.

The meaning was clear. Ammonia was apparently leaking into the Interface Heat Exchanger (IFHX) of the Low Temperature cooling Loop (LTL) in the Node 2 module.

“Flight, ETHOS, I expect the crew to be pressing in emergency response while I confirm,” said the flight controller from Environmental and Thermal Operating Systems (ETHOS). In other words, the crew needed to don oxygen masks to protect themselves from ammonia while ETHOS looked more closely at these data.

This was not a drill. When the red alarm appeared, the flight director turned her full attention to ETHOS. The words—unwelcome at any time from ETHOS—were especially jarring at an hour when the crew and the ground were humming along on a busy day of running experiments. Of the many failures for which the flight control team prepares, especially in simulations, this failure presents one of the most life-threatening situations, and one the team never wants to encounter on the actual vehicle.

On January 14, 2015, this scenario happened on the International Space Station (ISS). Data on the ETHOS console indicated toxic ammonia could be bleeding in from the external loops, through the waterbased IFHX, and into the cabin (see Chapter 11). Software on the ISS immediately turned off the fans and closed the vents between all modules to prevent the spread of ammonia. At the sound of the alarm, crew members immediately began their memorized response of getting to the Russian Segment (considered a safe haven, since that segment does not have ammonia systems) and closed the hatch that connected to the United States On-orbit Segment (USOS). They took readings with a sensitive sensor to determine the level of ammonia in the cabin. The flight control team—especially the flight director, ETHOS, and the capsule communicator (CAPCOM [a holdover term from the early days of the space program])—waited anxiously for the results while they looked for clues in the data to see how much, if any, ammonia was entering the cabin. Already, the flight director anticipated multiple paths that the crew and ground would take, depending on the information received.

No ammonia was detected in the cabin of the Russian Segment. At the same time, flight control team members looked at multiple indications in their data and did not see the expected confirming cues of a real leak. In fact, it was starting to look as if an unusual computer problem was providing incorrect readings, resulting in a false alarm. After looking carefully at the various indications and starting up an internal thermal loop pump, the team verified that no ammonia had leaked into the space station. The crew was not in danger. After 9 hours, the flight control team allowed the crew back inside the USOS. However, during the “false ammonia event,” as it came to be called, the team’s vigilance, discipline, and confidence came through. No panicking. Only measured responses to quickly exchange information and instructions.

Hearts were pumping rapidly, yet onlookers would have noticed little difference from any other day.

A key to the success of the ISS Program is that it is operated by thoroughly trained, well-prepared, competent flight controllers. The above example is just one of many where the team is unexpectedly thrust into a dangerous situation that can put the crew at risk or jeopardize the success of the mission. Both the flight controllers and the crews, often together, take part in simulations. Intense scenarios are rehearsed over and over again so that when a real failure occurs, the appropriate reaction has become second nature.

After these types of simulations, team members might figure out a better way to do something, and then tuck that additional knowledge into their “back pocket” in the event of a future failure. Perhaps the most famous example of this occurred following a simulation in the Apollo Program. After the instructor team disabled the main spacecraft, the flight controllers began thinking about using the lunar module as a lifeboat. When the Apollo 13 spacecraft was damaged significantly by an exploding oxygen tank, the flight control team already had some rough ideas as to what they might do. Since the scenario was not considered likely owing to all the safety precautions, the team had not developed detailed procedures. However, the ideas were there.

BEAM Work and Vision Checks for Crew Today

Astronaut Randy Bresnik
Astronaut Randy Bresnik enters the Bigelow Expandable Aerospace Module in July 31, 2017, when he was a Flight Engineer for Expedition 52.

More CubeSats were ejected from the International Space Station today to demonstrate and validate new technologies. Back inside the orbital lab, the Expedition 53 crew continued outfitting an experimental module and studying life science.

Two more tiny satellites were deployed from the Kibo laboratory module into Earth orbit today to research a variety of new technologies and space weather. One of the nanosatellites, known as TechEdSat, seeks to develop and demonstrate spacecraft and payload deorbit techniques. The OSIRIS-3U CubeSat will measure the Earth’s ionosphere in coordination with the Arecibo Observatory in Puerto Rico.

Commander Randy Bresnik was back inside the Bigelow Expandable Activity Module (BEAM) today with Flight Engineers Paolo Nespoli and Joe Acaba. The astronauts are converting the experimental habitat into a cargo platform by replacing old BEAM hardware with new electronics and stowage gear.

Eye exams are on the schedule this week as two cosmonauts and two astronauts took turns playing eye doctor and patient today. Alex Misurkin and Sergey Ryazanskiy of Roscosmos started first with the optical coherence tomography hardware using a laptop computer. Next, Nespoli and NASA astronaut Mark Vande Hei took their turn to help doctors on the ground understand the vision changes that take place in space.

BEAM Prepped for Cargo, CubeSats Deployed and Leg Muscles Scanned

An experimental module attached to the International Space Station is being prepared for upcoming cargo operations. Tiny research satellites were also ejected from the orbital lab while a pair of Expedition 53 crew members scanned their leg muscles today.

BEAM, officially called the Bigelow Expandable Activity Module, is being outfitted this week for future stowage operations. Excess gear, including inflation tanks and dynamic sensors, used during its initial expansion back in May of 2016 is being removed to make room for new cargo. BEAM’s old gear and trash will now be stowed in the Cygnus resupply craft for disposal early next month.

The Kibo lab module from the Japan Aerospace Exploration Agency was the site for the deployment of several CubeSats Monday morning. A mechanism attached to the outside of Kibo ejected the CubeSats that will orbit Earth and provide insights into antibiotic resistance, astrophysics and “space weather.” More CubeSats will be deployed Tuesday.

Flight Engineers Paolo Nespoli and Sergey Ryazanskiy spent Monday exploring how the lack of gravity affects leg muscles. Nespoli strapped himself into a specialized exercise chair and attached electrodes to his leg with assistance from Ryazanskiy. The Sarcolab-3 experiment uses measurements from an ultrasound device and magnetic resonance imaging to observe impacts to the muscles and tendons of a crew member.

Dragon Packing and BEAM Checks Onboard Station Today

Astronauts Peggy Whitson and Jack Fischer
NASA astronauts Peggy Whitson and Jack Fischer are pictured packing up gear inside the International Space Station.

The Expedition 52 crew is loading the SpaceX Dragon with cargo for return back to Earth in less than two weeks. BEAM, the experimental habitat, also received a new radiation shield today that was 3D printed aboard the International Space Station.

Dragon is due to leave the International Space Station July 2 after cargo transfers with the resupply ship are complete. The crew offloaded new science experiments, spacewalking gear and station hardware shortly after it arrived on June 5. Dragon will now be packed with used station gear and research samples for analysis by NASA engineers and scientists after it splashes down in the Pacific Ocean.

Flight Engineer Jack Fischer opened up BEAM today and entered the expandable activity module for a regular checkup. He replaced an older radiation shield with a thicker shield that covers a radiation sensor inside BEAM. Fischer also sampled BEAM’s air and surfaces for microbes.

Veteran astronaut Peggy Whitson of NASA spent Tuesday sampling the air and surfaces for microbes in the station’s U.S. segment. Whitson also spent some time stowing synthetic DNA samples exposed to radiation in a science freezer and began readying rodent research gear for return next month aboard Dragon.

This long-exposure photograph shows the docked Soyuz and Progress vehicles as the International Space Station orbits above the Earth.

The astronauts took a break from spacewalk preparations today and checked out an expandable module and worked on science freezers. The crew also continued its human research program exploring space nutrition and the effects of microgravity on metabolism and the immune system.

Thomas Pesquet opened the hatches to the Bigelow Expandable Activity Module (BEAM) today for a status check. The European Space Agency astronaut sampled BEAM’s air and surfaces for microbes and installed impact sensors. He also used a digital camera with a fish-eye lens to capture 360-degree imagery of the inside of BEAM.

Veteran NASA astronaut Peggy Whitson serviced three science freezers ensuring biological samples can be preserved for return on an upcoming SpaceX Dragon mission. She also brushed up on robotics skills necessary for Friday’s spacewalk.

Cosmonaut Oleg Novitskiy logged his meals again today before collecting saliva samples for an immunity study. Flight Engineer Andrey Borisenko researched how living in space long term affects metabolism and a crew member’s psychophysiological state.

BEAM Opens for Tests, Crew Checks Body Shape

Astronauts Peggy Whitson and Thomas Pesquet
Astronauts Peggy Whitson and Thomas Pesquet are pictured inside BEAM, the Bigelow Expandable Activity Module. Pesquet is also wearing the experimental SkinSuit.

BEAM was opened for a short time Thursday so the crew could install sensors inside the expandable module. The Expedition 50 space residents also explored how the body changes shape and how to prevent back pain during long-term missions.

BEAM, the Bigelow Expandable Activity Module, had its hatches opened temporarily so astronaut Peggy Whitson could install temporary sensors and perform a modal test, which has the astronaut use their fist to impart loads on the module. The sensors are measuring the resulting vibrations and how the module holds up to impacts. BEAM is an expandable habitat technology demonstration, which is a lower-mass and lower-volume system than metal habitats and can increase the efficiency of cargo shipments, possibly reducing the number of launches needed and overall mission costs.

Whitson also joined Commander Shane Kimbrough for body measurements to help NASA understand how living in space changes an astronaut’s physical characteristics. The duo collected video and imagery and measured chest, waist, hip arms and legs to help researchers learn how physical changes impact suit sizing.

An experimental suit called the SkinSuit is being studied for its ability to offset the effects of microgravity and prevent lower back pain and the stretching of the spine. Flight Engineer Thomas Pesquet wore the SkinSuit today and documented his comfort, range of motion and other aspects of the suit.

September was a busy month on the International Space Station filled with a wide variety of space research, a spacewalk, a crew departure and a test of the new BEAM module. One science highlight this month includes a new experiment that may improve how medicine works.

This week, astronaut Kate Rubins tested the endurance of the new Bigelow Expandable Aerospace Module in the vacuum of space. She also explored how solids dissolve in liquids to help the medicine industry design better performing drugs for humans on Earth and astronauts in space.

A new fuel burning study is about to start soon after Japanese astronaut Takuya Onishi completes the installation of the Group Combustion experiment. Results from the fire research could help engineers design advanced rocket engines and industrial furnaces. Onishi is also documenting his meals over the next few days for the ENERGY study. Onishi’s meal data in conjunction with his water and breath samples will help scientists understand the nutritional requirements necessary for long-term space missions.

Cosmonaut Anatoly Ivanishin, who took command of Expedition 49 on Sept. 6, has been working on the continuous upkeep of the Russian segment of the space station. The veteran cosmonaut has been preparing a Progress resupply ship for its Oct. 14 undocking. Some of the numerous Russian science experiments Ivanishin has been conducting have been observing the condition of the Earth and exploring human research.

BEAM, the new expandable module attached to the International Space Station, was opened up today for tests and equipment checks. The Expedition 49 crew also explored eating right in space, adapting to new technology and studied a variety of other life science and physics research.

Flight Engineer Kate Rubins opened up and entered the Bigelow Expandable Activity Module this afternoon. She temporarily installed gear inside BEAM for a test to measure the loads and vibrations the module experiences. Rubins started her day with a performance test on a mobile tablet device then videotaped her observations of the living conditions aboard the space station.

Japanese astronaut Takuya Onishi started an 11-day run today to document his meals while wearing a monitor that will take water samples and measure his breathing. The ENERGY experiment will help doctor’s understand metabolism in space and ensure astronauts are properly nourished to maintain the energy required for a long-term mission. Onishi is also continuing to set up the Group Combustion fuel burning study and checked for pressure leaks in the experiment gear.

In the Russian side of the orbital laboratory, Commander Anatoly Ivanishin resumed studying charged particle systems trapped in a magnetic field. He also participated in a pair of Earth photography experiments observing how natural and man-made disasters including industrial activities affect the land and sea.
