Crew Studies Exercise, Veins, and Plants Before Quartet’s Farewell

Space biology topped the research schedule aboard the International Space Station on Wednesday as the Expedition 72 crew explored how weightlessness affects exercising, veins, and plants. Meanwhile, four SpaceX Crew-8 members continue targeting Sunday, Oct. 13, for their departure, weather pending.

Scientists are studying how to work out effectively in microgravity to prevent space-caused accelerated bone and muscle loss. NASA Flight Engineer Don Pettit, with assistance from NASA Flight Engineer Matthew Dominick, set up high-definition video cameras and a motion capture system that monitored him while working out on the advanced resistive exercise device (ARED) in the Tranquility module. The ARED mimics the inertial forces of lifting free weights on Earth to maintain muscle health during long-term space missions. Pettit’s exercise session was for the ARED Kinematics study that compares the results of both Earth and space workouts to improve space exercise programs and counter musculoskeletal deconditioning.

Commander Suni Williams took charge as the crew medical officer on Wednesday and scanned the neck, shoulder, and leg veins of NASA Flight Engineer Nick Hague using the Ultrasound 2 device examining his circulatory health. Williams also configured radio frequency hardware and serviced samples for the Gaucho Lung drug treatment study. Hague installed biology imaging hardware in the Kibo laboratory module that can detect space-caused inflammatory changes in organisms.

NASA Flight Engineer Jeanette Epps spent her day replacing components that remove carbon dioxide and ethylene from inside Kibo’s Plant Habitat to support an upcoming space botany study. NASA Flight Engineers Mike Barratt and Butch Wilmore spent their day on maintenance as Barratt charged spacewalking tool batteries and Wilmore swapped out experimental hardware for an advanced life support system study.

Roscosmos Flight Engineer Alexander Grebenkin continued packing for his return to Earth targeted for no earlier than Sunday. He will return with fellow Crew-8 members Dominick, Barratt, and Epps aboard the SpaceX Dragon Endeavour spacecraft.

Biology, Physics Research Fill Schedule as Crew Awaits Departure

Space biology and physics were the main focus of research operations for the Expedition 72 crew aboard the International Space Station on Monday. Meanwhile, four Commercial Crew members are waiting for their final departure date before returning to Earth.

NASA Flight Engineer Nick Hague worked in the Columbus laboratory module swapping filters inside the BioLab’s incubator. BioLab supports the observation of microbes, cells, tissue cultures and more to understand the effects of weightlessness and radiation on organisms. NASA Flight Engineer Don Pettit set up a laptop computer on the Cell Biology Experiment Facility, a research incubator with an artificial gravity generator, located in the Kibo laboratory module.

Station Commander Suni Williams explored space physics on Monday mixing gel samples and observing with a fluorescence microscope how particles of different sizes gel and coarsen. Results are expected to benefit the medicine, food, and cosmetic industries. NASA astronaut Butch Wilmore, who has been aboard the station with Williams since June 6, trained to operate advanced life support gear installed in the Microgravity Science Glovebox for a different space physics experiment then relaxed the rest of the day.

Roscosmos Flight Engineer Aleksandr Gorbunov wore a sensor-packed cap that recorded his responses as he practiced futuristic planetary piloting techniques on computer. Flight Engineer Alexey Ovchinin inspected and cleaned the Electromagnetic Levitator that can levitate samples exposed to high temperatures for thermophysical research. Flight Engineer Ivan Vagner started out his day cleaning smoke detectors and testing batteries before ending his shift imaging Earth’s nighttime atmosphere in near-ultraviolet wavelengths.

NASA Flight Engineers Matthew Dominick and Mike Barratt, both SpaceX Crew-8 members, began the day in the Tranquility module unpacking and transferring cargo stowed in the NanoRacks Bishop airlock. More than just a stowage module, Bishop can also house science experiments that can also be placed in the external microgravity environment.

The two other crewmates representing Crew-8, Flight Engineers Jeanette Epps of NASA and Alexander Grebenkin of Roscosmos, spent their day packing cargo inside the Dragon Endeavour, handing over their mission responsibilities, and relaxing.
