<\/a><\/figure>Friday\u2019s schedule aboard the International Space Station<\/a> included maintenance and tech demonstration set up for the Expedition 73<\/a> crew.<\/p>\n In the Japanese Experiment Module<\/a> (JEM), NASA Flight Engineers Anne McClain<\/a> and Nichole Ayers<\/a> teamed up in the morning to remove MISSE<\/a> hardware and sample carriers before bagging them for return to Earth. The facility provides a unique platform for the testing of materials, coatings, and components in the space environment.<\/p>\n Afterward, the duo split up for a majority of the afternoon to focus on other tasks. McClain photographed tomato plants for a space agricultural study<\/a>, while Ayers set up ELVIS<\/a>\u2014a microscope for 3D imaging of objects such as bacteria\u2014in the Life Sciences Glovebox<\/a>. She then inserted Colwellia bacteria samples into GLACIER<\/a>, one of the station\u2019s ultra-cold freezers, before conducting a sample run to analyze the active behavior and genetic changes in the bacteria. Ayers and McClain were then joined by NASA Flight Engineer Jonny Kim<\/a> and current station commander Takuya Onishi of JAXA (Japan Aerospace Exploration Agency) for a conference with ground support.<\/p>\n Kim spent most of the day on maintenance and IT activities. He first set up hardware on the orbital lab\u2019s bicycle, CEVIS<\/a>, then scanned the disk drive of the Microgravity Science Glovebox<\/a> for any system errors. Later on, he conducted some computer hard drive tests, then took inventory of supplies in the Human Research Facility<\/a>.<\/p>\n Onishi had a light-duty morning before work picked up in the afternoon. In the Harmony Module<\/a>, he installed a crystallizer in the ADvanced Space Experiment Processor, or ADSEP<\/a>, a biotech facility that contains three thermal zones to accommodate a variety of experiments, including crystal growth. He then replaced the controller card in the Potable Water Dispenser<\/a> before setting up a tech demo<\/a> in JEM that will more efficiently transfer space-to-ground data. <\/p>\n The station\u2019s three Roscosmos cosmonauts, Alexey Zubritsky, Sergey Ryzhikov, and Kirill Peskov, all enjoyed a day off, relaxing and completing their routine two hours of daily exercise.<\/p>\n Learn more about station activities by following the\u00a0<\/em>space station blog<\/em><\/a>,\u00a0<\/em>@space_station<\/em><\/a>\u00a0and\u00a0<\/em>@ISS_Research<\/em><\/a>\u00a0on X, as well as the\u00a0<\/em>ISS Facebook<\/em><\/a>\u00a0and\u00a0<\/em>ISS Instagram<\/em><\/a>\u00a0accounts.<\/em><\/p>\n Get the latest from NASA delivered every week.
