Bacteria, brain aging and gravity-sensing cells were major research subjects on board International Space Station (ISS) on Friday, November 17. The seven Expedition 70 crew members also worked on computers, communications equipment and life support maintenance.

NASA Aerospace engineer Lorelle O’Hara investigated how microbes grow in microgravity, the potential damage they can cause to spacecraft, and ways to disinfect harmful bacteria. He injects microbial samples into a life science glovebox, which will be compared to non-inoculated samples. Funded by NASA Bacterial adhesion and erosion The study takes place at the Kibo Laboratory Module and aims to keep space crews and humans on Earth healthy.

Commander Andreas Mogensen from ESA (European Space Agency) looked at cell samples under a microscope Cerebral aging Experiment. It studies brain cell-like models to understand signs of accelerated aging seen in patients on Earth and seen in astronauts on long-duration space missions.

Astronaut Satoshi Furukawa Jaxa ( Japan Aerospace Exploration Agency ) Different cell samples were prepared and then sealed for observation under a confocal microscope. Cell Gravisensing Biological study. Earlier in the day, he had replaced hard drives on a laptop computer, then continued to help O’Hara unpack. SpaceX Dragon cargo ship.

NASA flight engineer Jasmine Mokbeli spends her day at Harmony Block building various NASA. Roscosmos Hardware. He first calibrated an ultrasonic probe device that uses high-frequency sound waves to analyze objects, and later, Mokbeli verified ground, VHF and inter-module communication systems from space.

Roscosmos cosmonaut Oleg Kononenko researched 3D printing techniques to learn how to make tools and materials in space and reduce dependence on cargo flights from Earth. Cosmonaut Nikolai Chub spent his day on life support and maintaining electronics. Cosmonaut Konstantin Borisov set up the Soyuz crew and Progress resupply ship laptop computers, then continued his photographic analysis of the station’s Roscosmos modules.
