Expedition 70 Flight Engineer and NASA astronaut Matthew Dominick smiles for a portrait during photography duties aboard the International Space Station.

A full day of orbital upkeep and maintenance kept the Expedition 71 crew busy on Monday as the septet continues to prepare the International Space Station for the arrival of two astronauts.

In the Tranquility module, NASA astronaut Matthew Dominick kicked off the morning by removing the top and bottom port stalls of the orbital lab’s toilet. Removing the stalls allowed him and his NASA crewmate, Tracy C. Dyson, to access the conductivity sensor and pump for repairs. The duo then worked together throughout the day to replace hardware in the station’s bathroom before reinstalling the port stalls and moving onto other work.

Once orbital plumbing duties wrapped, Dominick moved into the cupola, or “window to the world,” to inspect and photograph the conditions of the windows. Dyson assisted NASA astronaut Mike Barratt with a Dragon spacesuit check to ensure the suit and its components—such as the ear pieces, garment shirt, helmet visor, boots, and more—are still comfortable and working properly.

Barratt also conducted some maintenance on the station’s treadmill and his NASA crewmate, Jeanette Epps, performed maintenance on the Advanced Resistive Exercise Device, or ARED. Epps replaced the cable arm ropes on the device’s pulley system, then realigned the tension plates. Later on, she also completed a monthly inspection of the orbital outpost’s defibrillator.

In the Zarya module, Roscosmos Flight Engineer Alexander Grebenkin spent the entire day replacing different sections of soft air ducts. His crewmate, Nikolai Chub, did have some time to perform some science and ran an experiment that assesses the corrosion of various coatings and materials in microgravity. Station Commander Oleg Kononenko photographed Chub during the experiment, then moved on to assess the condition of surfaces throughout the Roscosmos segment.

On Earth, preparations continue for NASA’s Boeing Crew Flight Test ahead of the next launch opportunity, which is targeted for no earlier than 6:16 p.m. EDT Friday, May 17. NASA astronauts Butch Wilmore and Suni Williams returned to Houston over the weekend as work progressed on a valve replacement on the United Launch Alliance Atlas V rocket Centaur upper stage.

Space physics and life support maintenance topped the schedule at the end of the week for the Expedition 71 crew as the Starliner astronauts return to Houston. 3D printing and cargo operations also rounded out the operations aboard the International Space Station.

The coldest place in the universe may be the Cold Atom Lab located aboard the orbital outpost’s Destiny laboratory module. NASA Flight Engineer Mike Barratt opened up the quantum physics research device Friday morning and inspected its cables and ports as part of broader science hardware replacement work. The ultra-cold laboratory chills atoms to near absolute zero to observe their fundamental characteristics and quantum behaviors.

Barratt then joined NASA Flight Engineers Tracy C. Dyson and Matthew Dominick as they continued life support maintenance in the Tranquility module. Barratt activated the water processing assembly then reinstalled module components to their normal configuration in Tranquility. Dominick and Dyson spent the day in the module replacing hardware that supports the water recovery system which is part of the orbital outpost’s Waste and Hygiene compartment, or bathroom.

NASA Flight Engineer Jeanette Epps assisted Dyson at the end of the day finalizing cleanup activities in Tranquility after the advanced orbital plumbing work was complete. Epps began her shift in the Kibo laboratory module replacing obsolete gas bottles with new types of gas bottles in the Common Gas Supply Equipment rack. The gas supply hardware supplies gases including argon, helium, and carbon dioxide fueling research racks and their experiments inside Kibo.

Working in the orbiting lab’s Roscosmos segment, Commander Oleg Kononenko checked Soyuz communication systems, inspected video equipment, and cleaned vents on broadband hardware. Flight Engineer Nikolai Chub worked on a 3D printing experiment testing the device’s controller and software while printing an object. Chub also stowed trash and obsolete gear inside the Progress 86 resupply ship that is due to undock at the end of the month. Flight Engineer Alexander Grebenkin spent his day checking smoke detectors in the Nauka science module.

On the ground at NASA’s Kennedy Space Center in Florida, preparations continue ahead of the agency’s Boeing Crew Flight Test launch to the microgravity laboratory. NASA astronauts Butch Wilmore and Suni Williams, still in quarantine ahead of the flight test, will return to Houston this weekend as work progresses on a valve replacement on the United Launch Alliance Atlas V rocket Centaur upper stage. Crew will return to NASA Kennedy prior to the next launch opportunity, which is targeted for no earlier than 6:16 p.m. EDT on Friday, May 17, from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida.

Wilmore and Williams are the first to launch aboard Boeing’s Starliner to the space station as part of the agency’s Commercial Crew Program. The astronauts will spend about a week at the orbiting laboratory before returning to Earth and making a parachute and airbag-assisted landing in the southwestern United States.

After successful completion of the mission, NASA will finalize certification of Starliner and its systems for crewed rotation missions to the space station. The Starliner capsule, with a diameter of 15 feet (4.56 meters) and the capability to steer automatically or manually, will carry four astronauts, or a mix of crew and cargo, for NASA missions to low Earth orbit.

Dyson checks out an Astrobee robotic free-flyer for the Zero Robotics tech demonstration for an educational contest to write robot-controlling software.

The four astronauts aboard the International Space Station had a full schedule of science activities on Thursday while the three cosmonauts took the day off and spent time relaxing in the microgravity environment.

The Expedition 71 crew services not only life support systems and electronics gear, but also research hardware to ensure the ongoing operation and integrity of a multitude of science experiments. Thursday was no exception as the four on-duty astronauts from NASA worked on a multipurpose science rack, a fluid physics rack, and a CubeSat deployer.

Flight Engineer Tracy C. Dyson began her morning in the Columbus laboratory module replacing computer hardware in an EXPRESS rack. The rack, one of ten aboard the station, hosts and supports a variety of payloads and experiments. Astronauts as well as scientists on the ground can also monitor and control the rack facilities.

Working in the Destiny laboratory module, Flight Engineer Mike Barratt also replaced computer gear but inside the Fluids Integrated Rack. This rack enables research to understand how liquids behave in weightlessness potentially informing the design of fuel tanks and hydraulic systems for spacecraft.

The computers that support the different science hardware can store and downlink the research data. They also enable communications between payloads and other station components including the ability to command and control the space investigations.

Over in the Kibo laboratory module, Flight Engineer Matthew Dominick removed an empty CubeSat deployer from inside Kibo’s airlock. The deployer is routinely packed with CubeSats, grappled by the Japanese robotic arm in the depressurized airlock, and pointed away from the station to release the shoe box-sized satellites into Earth orbit. The CubeSats are developed by international educational and governmental organizations for numerous public research objectives.

Dominick and Barratt also partnered together and reviewed SpaceX Dragon Endeavour spacecraft procedures to maintain their operational proficiency. Dominick and Barratt are Commander and Pilot, respectively, for the SpaceX Crew-8 mission along with Mission Specialists Jeanette Epps of NASA and Alexander Grebenkin of Roscosmos. All four are also Expedition 71 Flight Engineers.

Epps and Barratt also took turns working in the Waste and Hygiene Compartment, the orbital lab’s bathroom, located in the Tranquility module. Barratt reinstalled and activated hardware that had been removed earlier in the week for orbital plumbing maintenance. Epps wrapped up the work stowing gear that had been replaced inside Tranquility.

The orbital outpost’s three cosmonauts including Grebenkin, Commander Oleg Kononenko, and Flight Engineer Nikolai Chub relaxed on Thursday taking time out for their regularly scheduled workouts. The trio from Roscosmos will be back on duty Friday for more science, cargo, and lab upkeep duties.

Microgravity science is the main mission aboard the International Space Station, however on Wednesday, the Expedition 71 crew focused primarily on life support maintenance. Nevertheless, the orbital septet did find time for cargo operations and biomedical research during a busy day full of hardware swaps.

NASA Flight Engineers Tracy C. Dyson and Matthew Dominick kicked off Wednesday swapping out advanced orbital plumbing gear that took up most of their day. The duo worked in the Tranquility module, where the orbital outpost’s restroom is located, and disconnected a host of cables and gear to access the station’s catalytic reactor. Dyson did the majority of the preparation work before Dominick assisted her and replaced the old catalytic reactor with a new one. The reactor introduces oxygen in the restroom’s water recovery system and oxidizes its wastewater.

Dominick wrapped up his shift transferring cargo in and out of the Northrop Grumman Cygnus space freighter. Cygnus has been berthed to the Earth-facing port on the Unity module since Feb. 1 when it delivered 8,300 pounds of cargo and science experiments.

At the end of the day, NASA astronauts Jeanette Epps and Mike Barratt finalized Dyson’s and Dominick’s life support upgrade work. Epps first installed a hose and a temporary filter in Tranquility to enable startup of the new catalytic reactor. After the startup was completed, the duo cleaned up Tranquility and returned the module’s systems to their normal configuration.

The orbital outpost’s three cosmonauts had their day full of human research activities while ensuring the ongoing upkeep of systems in the station’s Roscosmos segment. Commander Oleg Kononenko and Flight Engineer Nikolai Chub participated in hearing checks together wearing headphones connected to a computer and responding to a series of audio tones. Kononenko then moved on and refilled an oxygen generator in the Zvezda service module.

When Chub completed his hearing exam, he joined Flight Engineer Alexander Grebenkin for a fitness evaluation on a treadmill. The duo each took turns jogging on the treadmill while wearing sensors measuring health parameters such as heart rate and breathing rate. Grebenkin earlier conducted cardiac research for a long-running Roscosmos investigation.

Dyson and Jeanette Epps, both NASA astronauts, are pictured aboard the International Space Station’s Destiny laboratory module.

Payload maintenance and training topped Friday’s schedule aboard the International Space Station as the Expedition 71 septet gears up to welcome two new crew members next week.

On Thursday, May 2, four crew members entered the SpaceX Dragon spacecraft and relocated it to a different port to make room for the upcoming arrival of NASA’s Boeing Crew Flight Test. Dragon undocked from the Harmony module’s forward-facing port at 8:57 a.m. EDT and autonomously redocked to the module’s space-facing port at 9:46 a.m.

This move made Harmony’s forward port available for the arrival of Boeing’s Starliner spacecraft next week. Starliner is scheduled to launch from Space Launch Complex-41 at Cape Canaveral Space Force Station in Florida at 10:34 p.m. Monday, May 6, carrying NASA astronauts Butch Wilmore and Suni Williams to the station. The duo will enter Earth’s orbit and monitor the performance of spacecraft before docking to the orbital complex around 12:46 a.m. Wednesday, May 8.

Wilmore and Williams will spend about a week in low Earth orbit with the Expedition 71 crew to test Starliner and its subsystems before NASA certifies the transportation system for rotational missions to the orbiting laboratory as part of the agency’s Commercial Crew Program. NASA will broadcast the historic flight on NASA+, NASA TV, the NASA app, YouTube, and the agency’s website beginning at 6:30 p.m. Monday.

Aboard station, the septet split up maintenance duties on Friday. Flight Engineer Tracy C. Dyson of NASA began her day inspecting and photographing spacesuit power and data cables in preparation for upcoming spacewalks in June. Dyson then spent most of the day working with the Microgravity Science Glovebox, rotating the payload to clean its fans and screen, then activating it to support upcoming science investigations.

Flight Engineer Matthew Dominick of NASA removed and replaced the hydrogen sensor in the station’s oxygen generation system. He was later joined by his NASA crewmate, Mike Barratt, to test the health of the ventilation system in the U.S. segment and measured the airflow coming in and out of the vents.

The duo then joined NASA Flight Engineer Jeanette Epps and Roscsosmos Flight Engineer Alexander Grebenkin for a round of medical emergency training. The quartet reviewed procedures and hardware in the event a medical emergency requiring CPR were to occur on station.

After training, Epps removed and replaced the air filter in the wastewater processing system, then charged the Simplified Aid for EVA Rescue, or SAFER, batteries. Attached to the spacesuits astronauts don during spacewalks, SAFER allows a crew member to safely return to the station if they were to become untethered.

In the Zarya module, station Commander Oleg Kononenko removed and replaced ceiling panels. His Roscosmos crewmate, Nikolai Chub, practiced his piloting techniques during a Pilot-T session and later investigated the behavior of various liquid phases exposed to different temperatures and vibrations in the microgravity environment.
