The International Space Station hummed with activity on Thursday as the Expedition 65 crew gets ready for the next SpaceX Cargo Dragon mission and continues immune system research. All seven crew members also joined together and practiced their emergency response skills.
The Kibo laboratory module’s Life Sciences Glovebox (LSG) once again was the center of activity for NASA Flight Engineers Mark Vande Hei and Megan McArthur. The duo continued servicing donor cell samples inside the LSG, which are being compared to cells on Earth, as scientists document the significant differences in microgravity. The Celestial Immunity study’s results may provide insights into new vaccines and drugs and advance the commercialization of space.
At the end of the day, Vande Hei had his veins scanned with an ultrasound device operated by NASA Flight Engineer Shane Kimbrough. Kimbrough earlier joined Pesquet and inspected tethers to be used during a pair of upcoming spacewalks. The spacewalks are planned for June and will see the installation of the soon-to-be delivered solar arrays on the station’s Port 6 truss structure.
Finally, cosmonauts Oleg Novitskiy and Pyotr Dubrov joined their five crewmates and simulated an emergency aboard the station in conjunction with mission controllers on the ground. The drill consisted of locating emergency gear, practicing procedures and decision-making, and coordinating communications with controllers in Houston and Moscow.
Vande Hei later had his eyes checked at the end of the day by NASA Flight Engineer Shane Kimbrough using near-infrared medical-imaging for detailed views of his retina. Kimbrough also worked throughout the day replacing life support components inside a U.S. spacesuit before organizing Russian spacewalk tools.
Ear checks were on the schedule on Wednesday with Kimbrough, ESA Flight Engineer Thomas Pesquet and station Commander Akihiko Hoshide taking a hearing test using specialized audio software. The three astronauts individually took the hearing assessment isolated in their private crew quarters to block out external station sounds.
Hoshide began the morning collecting and stowing his urine samples before spending the rest of the day on lab maintenance and inventory tasks. Pesquet demonstrated a simple heat transfer experiment for kids. He then checked out the immersive Sidekick device that displays high-definition holograms to assist crews with science and maintenance tasks.
Veteran cosmonaut Oleg Novitskiy worked on Russian maintenance tasks and continued packing the U.S. Cygnus space freighter ahead of its departure in a few weeks. First time space-flyer Pyotr Dubrov had orbital plumbing duties Wednesday morning and checking station cameras and ventilation systems.
The Water Processor Assembly (WPA) in the Tranquility module has been powered off due to a possible leak. This hardware is used to recycle water from multiple sources into clean, drinkable water for crew members aboard the International Space Station.
The crew is in no danger and has multiple spare parts aboard to begin the repair process which is expected to be complete early next week. Enough water is stored on the space station to provide the crew with the necessary consumables for several months if required.
The space station serves a vital role in testing and maturing life support technologies that will be required for future missions to the Moon and Mars. Repairs provide invaluable data to engineers refining these systems for use in future spacecraft and missions.
Human research took precedence aboard the International Space Station on Tuesday as the Expedition 65 crew explored how weightlessness affects the immune system. The orbital residents also trained for a medical emergency and ensured station systems continued operating in tip-top shape.
McArthur started her day with NASA Flight Engineer Shane Kimbrough collecting blood samples, spinning them in a centrifuge and stowing them in a science freezer for later analysis. Kimbrough then spent the rest of Tuesday replacing fans that cool science racks in the U.S. Destiny laboratory module.
Station Commander Aki Hoshide started the fan replacement work before swapping out life support components in the Tranquility module. At the end of the day, he and ESA Flight Engineer Thomas Pesquet stowed hardware in Tranquility’s end cone. Pesquet also packed the Northrop Grumman Cygnus space freighter with trash and discarded gear ahead of its departure in a few weeks.
Vande Hei joined his Soyuz MS-18 crewmates Oleg Novitskiy and Pyotr Dubrov and trained for the unlikely event of a medical emergency in space. The trio reviewed medical hardware, performed simulated chest compressions, and practiced communication and coordination.
The seven orbital residents that comprise the Expedition 65 crew aboard the International Space Station took a well-deserved day off on Monday. May looks to be relaxed month, following a very busy April, with no spacecraft activities on the calendar until June.
It was a three-day weekend on the orbiting lab today as the five astronauts and two cosmonauts took Monday off. The septet cleared its schedule for personal activities such as looking at the Earth below, talking to family, watching movies and playing games.
The crewmates continued their daily workouts as each crew member exercises about two hours a day to counteract the lack of gravity on their bodies. There are U.S. and Russian treadmills, an exercise cycle and an advanced resistive exercise device that the space residents use to maintain muscle and bone health in weightlessness.
There were also urine sample collections aboard the orbital lab today which are part of a variety of ongoing studies into the effects of long-term spaceflight on humans. Those samples were stowed in a science freezer for later analysis by scientists on Earth.
The next cargo mission planned to replenish the Expedition 65 crew is targeted for launch on June 3. The SpaceX Cargo Dragon will lift off from the Kennedy Space Center and dock on June 4 to the Harmony module’s space-facing international adapter. The Cargo Dragon will deliver new solar arrays to augment the space station’s power system.
NASA and its international partners take advantage of the weightless environment of the orbiting lab to gain new insights unattainable due to Earth’s gravity. They use the knowledge from the long-term microgravity research to improve conditions for humans on and off the planet.
A new study recently delivered to the station aboard the SpaceX Crew Dragon Endeavour is exploring how the immune system adapts to microgravity. NASA Flight Engineer Megan McArthur set up hardware and samples for the Celestial Immunity investigation inside the Life Science Glovebox today. Results may provide new vaccines and medicines for diseases on Earth and increase the potential for commercialization of space.
Flight Engineer Thomas Pesquet of ESA (European Space Agency) partnered with Vande Hei for some of the life support work on Friday. Pesquet also transferred the AstroPi science computer to the Columbus laboratory module after joining NASA Flight Engineer Shane Kimbrough for orbital plumbing work in the Tranquility module. Additionally, Kimbrough spent a few hours installing power equipment and routing cables inside Tranquility before collecting and stowing his urine samples for later analysis.
Cosmonaut Oleg Novitskiy, also a three-time space visitor, worked on Russian communications gear and power tools before exchanging samples for a semiconductor crystal study. Roscosmos Flight Engineer and first-time space flyer Pyotr Dubrov spent the day on plumbing and ventilation tasks in the station’s Russian segment.
