NASA Space Station On-Orbit Status 29 October 2020 - Keeping the Astronauts Healthy

Hurricane Zeta was pictured from the International Space Station.

The three-member Expedition 64 crew is helping scientists understand how to keep astronauts healthy and maintain spacecraft systems on long-term exploration missions.

The trio aboard the International Space Station also cleaned lab ventilation systems and worked on orbital plumbing tasks.

Flight Engineer Kate Rubins of NASA had a regularly scheduled health check up this morning and measured her temperature, blood pressure, pulse, and respiratory rate. Afterward, she serviced computer components that support the European Physiology Module which enables neuroscientific, cardiovascular, and physiological studies.

Rubins then spent the rest of the afternoon in the U.S. Destiny laboratory module installing fluid physics hardware inside the Microgravity Science Glovebox. The gear is for the Drop Vibration study that may provide engineers insights into designing advanced spacecraft systems and fabricating semiconductors on Earth.

Research into space exercise is ongoing inside the station as doctors around the world study how to keep crew members in good shape while living and working in weightlessness. Once again, Commander Sergey Ryzhikov and Flight Engineer Sergey Kud-Sverchkov attached variety of sensors to themselves and worked out Thursday morning providing insights into how their bodies react to physical activities in space.

Ryzhikov then moved on to Russian plumbing work and transferred urine from the station into tanks located on the Progress 76 resupply ship. Kud-Sverchkov was in the Zvezda service module during the afternoon working preventive maintenance on the ventilation system's fans and filters.

Drop Vibration Setup: The crew performed the necessary steps to install the Drop Vibration hardware in the Microgravity Sciences Glovebox (MSG). Although we were able to get the hardware installed successfully, the team is discussing some video issues which were encountered at the end of the activity. Inertial Spreading with Vibration and Water Coalescence (Drop Vibration) examines the behavior of big liquid drops whose perimeter of contact, called the contact line, moves rapidly as the drops change shape either forced by vibration or freely by merger. These motions, fast and small on Earth, become slower and larger in microgravity and so can be more closely observed. Such observations improve the currently limited understanding of contact lines, important in applications such as self-cleaning surfaces, water harvesting devices, anti-frost coatings and the fabrication of semiconductors.

EPM (European Physiology Module) Board Removal: In a continuation of the troubleshooting for the EPM Rack, the crew removed Science Module Support Computer (SMSC) Extension Board 3. Recovery of the EPM rack will simplify GRIP science operations in the next few weeks, but a work-around is in place if the troubleshooting is not successful. This EPM SMSC issue first occurred on 01 September of this year. EPM is designed to investigate the effects of short- and long-duration space flight on the human body. It includes equipment for neuroscientific, cardiovascular, and physiological studies.
