Microgravity causes changes in human immune cells that resemble this condition but happen faster than the actual process of aging on Earth. The\u00a0<strong>Immunosenescence<\/strong>\u00a0investigation, sponsored by the\u00a0<strong>ISS National Lab<\/strong>, takes advantage of this fact, using tissue chips to study how microgravity affects immune function during flight and whether immune cells recover post-flight.\u00a0<strong>Tissue chips<\/strong>\u00a0are small devices that contain human cells in a 3D structure, allowing scientists to test how those cells respond to stresses, drugs, and genetic changes. Results could support development of treatments to protect astronauts during future long-duration spaceflight, and lead to development of more effective treatments for immune system aging on Earth. During the week, crew members changed media in the Life Sciences Glovebox (<strong>LSG<\/strong>) and collected samples for the investigation.<\/p>\n\n\n\n<p><strong>Superior optical fibers<\/strong><\/p>\n\n\n\n<p><strong>Fiber Optic Production-2<\/strong>\u00a0, sponsored by the\u00a0<strong>ISS National Lab<\/strong>, builds on previous work to develop the technology for manufacturing commercial optical fibers in microgravity using a blend of elements called ZBLAN. Earlier studies suggest that ZBLAN optical fibers produced in microgravity exhibit qualities superior to those produced on Earth. These fibers are difficult to manufacture on Earth and this investigation could help guide manufacture of optical fiber aboard the space station for commercial use. Potential applications of the fibers in space include remote sensing, Light Detection and Ranging (LIDAR), hyperspectral imaging, atmospheric monitoring, and optical data communications. ZBLAN optical fibers manufactured in space also have many potential applications on Earth, including improved data transmission for telecommunications and use in devices for spectroscopy, laser surgery, remote sensing, and environmental monitoring. Crew members installed and assembled components for the investigation inside the station\u2019s Microgravity Science Glovebox (<strong>MSG<\/strong>) during the week.<\/p>\n\n\n\n<p><strong>Purer protein crystals<\/strong><\/p>\n\n\n\n<p><strong>Advanced Nano Step<\/strong>, an investigation from the Japan Aerospace Exploration Agency (JAXA), monitors and records how specific impurities affect the development and quality of protein crystals grown in microgravity. Protein crystals grown in microgravity are known to be of higher quality than those grown on Earth, but the success rate is at most 20-60% better. This investigation aims to improve that rate and help scientists understand the kinds of impurities that deteriorate protein crystal quality. Researchers plan to return the crystals to Earth for analysis via synchrotron X-ray diffraction. Advanced Nano Step could significantly improve efforts to exclude impurities before launch. This knowledge also could be useful for crystallization trials conducted with diffusion-limited growth methods on Earth, such as with gel growth methods. During the week, crew members conducted operations for the investigation.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" width=\"1024\" height=\"683\" src=\"http:\/\/www.dereumlabs.com\/global\/wp-content\/uploads\/2022\/07\/Astronauta-1024x683.jpg\" alt=\"Station\" class=\"wp-image-351\" srcset=\"http:\/\/www.dereumlabs.com\/global\/wp-content\/uploads\/2022\/07\/Astronauta-1024x683.jpg 1024w, http:\/\/www.dereumlabs.com\/global\/wp-content\/uploads\/2022\/07\/Astronauta-300x200.jpg 300w, http:\/\/www.dereumlabs.com\/global\/wp-content\/uploads\/2022\/07\/Astronauta-768x512.jpg 768w, http:\/\/www.dereumlabs.com\/global\/wp-content\/uploads\/2022\/07\/Astronauta-1536x1024.jpg 1536w, http:\/\/www.dereumlabs.com\/global\/wp-content\/uploads\/2022\/07\/Astronauta-2048x1366.jpg 2048w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><figcaption>NASA astronaut Kjell Lindgren works on Forward Osmosis Membrane, an investigation that tests technology for water reclamation in microgravity for possible use on future space exploration missions.<\/figcaption><\/figure>\n\n\n\n<p><strong>Other investigations involving the crew:<\/strong><\/p>\n\n\n\n<ul><li><strong>Forward Osmosis Membrane<\/strong>\u00a0tests whether reactive membranes, which show promise for water reclamation on the ground, perform in microgravity.
