Microgravity Mysteries: Bacteria, Brain Aging, and Gravity-Sensing Cells in Space

Bacteria, brain aging, and gravity-sensing cells were the main research subjects aboard the International Space StationThe International Space Station (ISS) is a large spacecraft in orbit around the Earth that serves as a research laboratory and spaceport for international collaboration in space exploration. It was launched in 1998 and has been continuously occupied by rotating crews of astronauts and cosmonauts from around the world since 2000. The ISS is a joint project of five space agencies: NASA (USA), Roscosmos (Russia), JAXA (Japan), ESA (Europe), and CSA (Canada). It orbits the Earth at an altitude of approximately 400 kilometers (250 miles), and provides a unique platform for scientific research, technological development, and human space exploration.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>International Space Station (ISS) on Friday, November 17. The seven Expedition 70 crew members also worked on computers, communications gear, and life support maintenance to wrap up the work week.

NASAEstablished in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is "To discover and expand knowledge for the benefit of humanity." Its core values are "safety, integrity, teamwork, excellence, and inclusion." NASA conducts research, develops technology and launches missions to explore and study Earth, the solar system, and the universe beyond. It also works to advance the state of knowledge in a wide range of scientific fields, including Earth and space science, planetary science, astrophysics, and heliophysics, and it collaborates with private companies and international partners to achieve its goals.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>NASA Flight Engineer Loral O’Hara explored how microorganisms grow in microgravity, the potential damage they cause to spacecraft, and ways to disinfect the harmful bacteria. She inoculated microbe samples inside the Life Science Glovebox that will be compared to uninoculated samples. The NASA-sponsored Bacteria Adhesion and Corrosion study takes place in the Kibo laboratory module and aims to keep space crews and humans on Earth healthy.

Commander Andreas Mogensen from ESA (European Space AgencyThe European Space Agency (ESA) is an intergovernmental organization dedicated to the exploration and study of space. ESA was established in 1975 and has 22 member states, with its headquarters located in Paris, France. ESA is responsible for the development and coordination of Europe's space activities, including the design, construction, and launch of spacecraft and satellites for scientific research and Earth observation. Some of ESA's flagship missions have included the Rosetta mission to study a comet, the Gaia mission to create a 3D map of the Milky Way, and the ExoMars mission to search for evidence of past or present life on Mars.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>European Space Agency) viewed cell samples under a microscope for the Cerebral Ageing experiment. The study looks at brain cell-like samples to understand accelerated aging symptoms seen in patients on Earth and observed in astronauts on long-term space missions.

Astronaut Satoshi Furukawa from JAXAFormed in 2003, the Japan Aerospace Exploration Agency (JAXA) was born through the merger of three institutions, namely the Institute of Space and Astronautical Science (ISAS), the National Aerospace Laboratory of Japan (NAL) and the National Space Development Agency of Japan (NASDA). JAXA performs various activities related to aerospace, from basic research in the aerospace field to development and utilization and is responsible for research, technology development, and launch of satellites into orbit, and is involved in advanced missions such as asteroid exploration and possible human exploration of the Moon.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>JAXA (Japan Aerospace Exploration Agency) prepared different cell samples for observation inside the Confocal Microscope then closed out the Cell Gravisensing biology Investigation.

It was formed in 2015 through the merger of the Federal Space Agency (Roscosmos) and the United Rocket and Space Corporation. Roscosmos is responsible for Russia's space program and works closely with other international space agencies on joint projects, such as the International Space Station. The agency is also involved in a wide range of space-related activities, including scientific research, earth observation, telecommunications, and manned spaceflight.” data-gt-translate-attributes=”[{“attribute”:”data-cmtooltip”, “format”:”html”}]”>Roscosmos hardware.

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