Space Medicine, Lab Upkeep Top Thursday’s Station Schedule

Space medicine, spacesuits, and eye checks filled the schedule aboard the International Space Station on Thursday. Cargo operations and life support maintenance rounded out the day as the Expedition 72 crew awaits the departure of four crewmates.

Scientists are continually using the orbiting lab’s microgravity environment to explore new phenomena not possible on Earth to promote industry and human health. Thursday’s space research explored ways to improve treatments for patients on Earth and keep astronauts healthy on long-term missions.

NASA Flight Engineer Butch Wilmore serviced samples and observed how fluids flow using capillary force to understand how liquid drugs are transported in the lungs. Results may benefit the health care and food industries with improved respiratory therapies and better contamination prevention techniques.

NASA Flight Engineers Matthew Dominick and Don Pettit worked on advanced research gear ensuring it remains operable for high-quality results. Dominick organized the hardware inside the BioServe centrifuge that supports a range of science from DNA studies, to materials research, and more in space. Pettit replaced cables on the Cell Biology Experiment Facility, an incubator with an artificial gravity generator. Pettit also collected and stowed his urine samples in a science freezer for later analysis. He finally joined Flight Engineer Nick Hague for eye exams using medical imaging gear with assistance from doctors on the ground. Hague earlier relocated air sensors from the Destiny laboratory module to the Tranquility module.

Lab maintenance is also key aboard the orbital outpost to ensure ongoing science operations and healthy crews. Commander Suni Williams and Flight Engineer Jeanette Epps, both NASA astronauts, serviced thermal systems and orbital plumbing components, while also organizing food stowed in the Unity module. NASA Flight Engineer Mike Barratt spent his shift in the Quest airlock dumping and filling spacesuit water tanks then  cleaning Quest’s smoke detectors.

Roscosmos Flight Engineer Ivan Vagner completed his 24-hour heart monitoring session on Thursday and handed over the sensors to Flight Engineer Alexey Ovchinin so he could record his heart rate. Vagner also swapped out orbital plumbing gear in the Nauka science module while Ovchinin replaced hydraulic pumps in the Zvezda service module. Flight Engineer Alexander Grebenkin continued photographing crew activities for documentation while Flight Engineer Aleksandr Gorbunov jogged on a treadmill for a regularly schedule fitness evaluation.

Dragon Operations Underway During Advanced Biology Studies

Dragon spacecraft operations were underway aboard the International Space Station on Friday as four crew members prepare to return to Earth and another quartet prepares to swap docking ports. Meanwhile, microgravity science continued apace as the Expedition 72 crew explored how weightlessness affects stem cells, plant growth, and equilibrium.

NASA’s SpaceX Crew-8 mission is about to complete a seven-month mission aboard the orbital outpost that began on March 3. The homebound quartet, with NASA astronauts Matthew Dominick, Mike Barratt, and Jeanette Epps and Roscosmos cosmonaut Alexander Grebenkin, completed final reviews on Friday for their departure aboard the Dragon Endeavour spacecraft targeted for Sunday at 6:05 a.m. EDT.

NASA+ will stream Crew-8’s hatch closing and undocking from the Harmony module’s space-facing port beginning at 4 a.m. on Sunday. NASA+ will also start its live coverage of Crew-8’s return to Earth at 2:30 p.m. on Monday before Dragon splashes down at 3:38 p.m., pending weather. Learn how to watch NASA content through a variety of platforms, including social media.

The most recent Dragon spacecraft to visit the orbital outpost, Freedom, will switch docking ports a few days after Endeavour competes its mission. Crew-9 Commander Nick Hague from NASA will lead NASA astronauts Suni Williams and Butch Wilmore along with cosmonaut Aleksandr Gorbunov aboard Freedom during the quick ride from Harmony’s forward port to the port vacated by Crew-8. The foursome spent about an hour on Friday training for their relocation activities. NASA+ will cover the relocation activities live when mission managers finalize a time and date for Dragon’s port switch.

The Dragon crew members are still a part of the 11-member Expedition 72 crew and kept up their advanced space research activities on Friday helping NASA and its international partners keep humans healthy on and off the Earth. Williams and Wilmore serviced stem cell samples for microscope operations to learn how to treat blood diseases and cancers. Dominick and Epps were back on space botany research investigating how plants absorb water in space to support self-sufficient missions farther away from Earth. Barratt uninstalled and stowed hardware that enabled observations of how plants grow in the microgravity and radiation environment. Finally, Hague joined NASA Flight Engineer Don Pettit, who arrived at the orbiting lab aboard the Soyuz MS-26 crew ship, for eye scans with the Ultrasound 2 device.

The two cosmonauts who launched to space with Pettit, Flight Engineers Alexey Ovchinin and Ivan Vagner, took turns exploring how the lack of gravity affects their sense of balance, vision, and other sensory cues. The pair attached sensors near their eyes and ears and wore virtual reality goggles that tracked their eye movements to improve astronaut training and adaptation and promote therapies for patients on Earth.

Station Keeps Up Biology Studies as Crew-8 Nears Departure

The Expedition 72 crew members explored how space affects exercise and plant growth on Thursday helping NASA and its international partners plan human missions farther away from Earth. The International Space Station residents are also preparing for the departure of four crewmates and continuing to maintain science and life support systems.

The lack of gravity accelerates the loss of bone and muscle mass in crew members living and working in the weightless environment of space. As a result, astronauts exercise for two hours every day to counter the space-caused physical deconditioning and maintain their health ensuring mission success. Researchers monitored NASA Flight Engineer Nick Hague as he pedaled on an exercise cycle while attached sensors and wearing breathing gear that measured his aerobic capacity. Roscosmos Flight Engineer Ivan Vagner jogged on a treadmill for a regularly scheduled fitness evaluation. Researchers monitor the workout sessions and analyze the data to ensure safe and effective workouts while living in microgravity.

Hague also joined station Commander Suni Williams and Flight Engineer Butch Wilmore, both NASA astronauts, and reviewed emergency hardware and procedures in the SpaceX Dragon Freedom spacecraft. The NASA trio then teamed up with Roscosmos Flight Engineer Aleksandr Gorbunov and called down to Earth for a conference with SpaceX mission controllers. Gorbunov launched to space aboard Freedom with Hague on Sept. 28. Williams and Wilmore will return to Earth with the Freedom  duo in February of 2025.

NASA Flight Engineers Matthew Dominick and Mike Barratt spent all day Thursday studying how to water plants in space. Barratt set up space botany hardware in the Harmony module while Dominick performed research operations for the Plant Water Management 5 experiment. The investigation explores using low-gravity watering methods such as hydroponics and aeroponics to support plant growth in space.

NASA Flight Engineers Don Pettit and Jeanette Epps focused on science maintenance during their shifts on Thursday. Pettit calibrated biology imaging hardware in the Kibo laboratory module that can detect space-caused inflammatory changes in organisms. Epps packed stem cell research hardware for return to Earth then powered down the KERMIT fluorescence microscope used to image the stem cell samples.

Meanwhile, Epps and her fellow SpaceX Crew-8 crewmates Dominick, Barratt, and Roscosmos cosmonaut Alexander Grebenkin called to Mission Control in Houston on Thursday and gave their farewell remarks. The Commercial Crew quartet is targeted to undock from the Harmony’s space-facing port aboard SpaceX Dragon Endeavour no earlier than 3:05 a.m. EDT on Sunday, weather pending. NASA+ will broadcast the crew departure activities and Dragon’s parachute-assisted splashdown the following day at a site to be determined. Learn how to watch NASA content through a variety of platforms, including social media.

Watch the farewell remarks on YouTube.

Finally, Roscosmos cosmonaut Alexey Ovchinin started his day on a space physics experiment studying how free-flying objects in microgravity move in relation to the speed and trajectory of the space station. Afterward, he spent the rest of his day servicing Roscosmos computers and ventilation systems.
