Crew Works Human Research and Payload Prep, Orbital Upkeep Continues

Orbital upkeep was at the forefront of Wednesday’s schedule aboard the International Space Station, but the Expedition 71 crew did have some time to conduct human health research and prepare scientific payloads for future operations.

NASA Flight Engineer Mike Barratt spent the morning completing tasks for the CIPHER investigation, collecting blood samples—with assistance from NASA Flight Engineer Jeanette Epps—and completing a cognition test. CIPHER, or the Complement of Integrated Protocols for Human Exploration Research, helps scientists on Earth pinpoint how the human body reacts to long-duration missions in space.

After human research activities wrapped, Barratt moved into the Destiny laboratory module to help NASA Flight Engineer Tracy C. Dyson install a vacuum jumper to the Major Constituent Analyzer, which checks the quality of the orbital complex’s air. The duo was then joined by Epps and NASA Flight Engineer Matthew Dominick for a midday conference with ground teams.

Epps also spent the day gathering kits for future Immunity Assay operations and setting up Kubik, an incubator designed to study biological samples in microgravity. In the afternoon, she worked on cargo operations, stowing items in Northrop Grumman’s Cygnus spacecraft.

Dyson and Dominick worked on additional orbital plumbing tasks throughout the day, inspecting the toilet after wrapping up maintenance and re-installing the port stalls to the bathroom. The duo also worked inside the station’s cupola, or “window to the world,” separately to clean the area and its seven windows.

Near the end of the day, Dyson removed and replaced samples from the Materials Science Lab and prepared the payload for its next sample run, while Dominick completed some on-orbit medical training.

In the Zarya module, current station Commander Oleg Kononenko ran the 3D printer, while Flight Engineer Alexander Grebenkin completed some computer maintenance. Later on, Grebenkin practiced his piloting techniques during a Pilot-T session, and his Roscosmos crewmate, Nikolai Chub, investigated the behavior of liquid phases exposed to different temperatures and vibrations in microgravity.

On Earth, NASA, Boeing, and ULA (United Launch Alliance) teams continue working remaining open tasks in preparation for the agency’s Boeing Crew Flight Test to the International Space Station. The teams now are targeting a launch date of no earlier than 4:43 p.m. EDT on Tuesday, May 21, to complete additional testing. For more information, please visit the CFT blog.

Crew Works Maintenance; NASA, Boeing Target No Earlier Than May 21 for Launch

While science often occupies the crew schedule aboard the International Space Station, upkeep of the orbiting complex is just as important to ensure the longevity of microgravity operations. On Tuesday, the Expedition 71 septet spent another full day conducting maintenance on scientific payloads and life support systems.

NASA Flight Engineer Jeanette Epps kicked off the day preparing measurement aids for crew quarter inspections that were conducted later in the day. Afterward, Epps charged spacesuit batteries in preparation for a round of spacewalks this summer, then moved into the Tranquility module to collect and analyze samples from the Water Processor Assembly, which provides clean, drinkable water for crew members after being recycled from multiple sources.

After Epps prepped the measurement aids, NASA Flight Engineer Matthew Dominick entered the crew quarters to take airflow measurements from the intake ducts. Dominick then continued orbital plumbing work he began yesterday, removing and replacing some hoses, the air filter, and wastewater filter in the station’s toilet. He completed the day by reactivating the bathroom and stowing tools used for the repairs.

Though maintenance was at the forefront of today’s microgravity work, Flight Engineer Mike Barratt did have some time to collect biological samples for ongoing human research. CIPHER, or the Complement of Integrated Protocols for Human Exploration Research, is a suite of total-body experiments that help researchers pinpoint how the human body reacts to long-duration missions in space. Through the collection of biological samples, scientists can examine changes to cartilage health, inflammation and immune function, kidney health, and more.

After his human research activities, Barratt moved into the Destiny laboratory module to service the Cold Atom Lab, which chills atoms to near absolute zero to observe the fundamental behaviors and quantum characteristics that are difficult or impossible to probe at higher temperatures. Barratt reconnected power and data cables and the filter to the quantum physics device.

Following Dominick’s intake duct measurements in the morning, NASA Flight Engineer Tracy C. Dyson spent the afternoon in the crew quarters taking additional measurements. She was also joined by cosmonaut and current space station Commander Oleg Kononenko and Flight Engineer Nikolai Chub to complete some on orbit medical training, reviewing procedures that would need to be taken in the event an emergency were to occur on station that requires the use of CPR.

In the Zarya module, Flight Engineer Alexander Grebenkin of Roscosmos assessed lighting conditions throughout the segment, then ran a distillation cycle on the wastewater processor.

On Earth, NASA, Boeing, and ULA (United Launch Alliance) teams continue working remaining open tasks in preparation for the agency’s Boeing Crew Flight Test to the International Space Station. The teams now are targeting a launch date of no earlier than 4:43 p.m. EDT on Tuesday, May 21, to complete additional testing. For more information, please visit the CFT blog.

NASA’s Boeing Crew Flight Test Eyes Next Launch Opportunity

NASA, Boeing, and ULA (United Launch Alliance) teams continue working remaining open tasks in preparation for the agency’s Boeing Crew Flight Test to the International Space Station. The teams now are targeting a launch date of no earlier than 4:43 p.m. EDT on Tuesday, May 21, to complete additional testing.

On May 11, the ULA team successfully replaced a pressure regulation valve on the liquid oxygen tank on the Atlas V rocket’s Centaur upper stage. The team also performed re-pressurization and system purges, and tested the new valve, which performed normally.

Starliner teams are working to resolve a small helium leak detected in the spacecraft’s service module traced to a flange on a single reaction control system thruster. Helium is used in spacecraft thruster systems to allow the thrusters to fire and is not combustible or toxic.

NASA and Boeing are developing spacecraft testing and operational solutions to address the issue. As a part of the testing, Boeing will bring the propulsion system up to flight pressurization just as it does prior to launch, and then allow the helium system to vent naturally to validate existing data and strengthen flight rationale. Mission teams also completed a thorough review of the data from the May 6 launch attempt and are not tracking any other issues.

The Atlas V and Starliner remain in the Vertical Integration Facility at Space Launch Complex-41 on Cape Canaveral Space Force Station in Florida.

NASA astronauts Butch Wilmore and Suni Williams, still in preflight quarantine, returned to Houston on May 10 to spend extra time with their families as prelaunch operations progress. The duo will fly back to NASA’s Kennedy Space Center in Florida in the coming days.

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 begin the final process of certifying Starliner and its systems for crewed rotation missions to the space station.

Station Maintenance and Upkeep Top Monday’s Schedule

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. For the latest on the mission, please visit NASA’s blog.

Space Physics Aboard Station as Starliner Crew Returns to Houston

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.
