Biomedical monitoring continued aboard the International Space Station on November 6 while other crew members serviced equipment after the previous day’s spacewalk. Sergey Teteryatnikov took blood-pressure measurements with cuffs on his arm, wrist and finger, then exercised on a treadmill with electrodes recording heart and breathing rates.

The measurements support research into how weightlessness affects the cardiovascular and respiratory systems. Commander Pyotr Dubrov also completed an overnight carbon-dioxide monitoring session and sent its data to ground controllers. These are reported research and monitoring activities; NASA’s account does not announce a new medical finding.

Elsewhere, Joshua Kutryk and Anil Menon prepared spacesuits and tools for future excursions. Their work included replenishing water tanks, clearing air bubbles, fitting rechargeable batteries and inspecting gear. Jessica Watkins and Luke Delaney joined a discussion with ground engineers about the November 5 excursion. The operational follow-up comes after installation of the eighth roll-out solar array, which completed the station’s power-capacity upgrade from 160 to 215 kilowatts.
