After a weekend that included the 237th spacewalk in support of assembly and maintenance for the International Space Station, featuring spacewalkers and NASA astronauts\u00a0Victor Glover<\/a>\u00a0and\u00a0Michael Hopkins<\/a>, the Expedition 64<\/a> crew members got back to the business of science, switching out hardware and working around a comprehensive emergency drill on Monday.<\/p>\n Running through the emergency drill, the crewmates practiced their roles during various emergency scenarios, such as who would manage the procedures, gather equipment, and close hatches, all while maintaining constant communication with teams on the ground in Mission Control.<\/p>\n NASA Flight Engineer Shannon Walker<\/a> performed post-spacewalk recharge maintenance to the Extravehicular Mobility Unit suits used in Saturday\u2019s excursion, stowing them for later use.<\/p>\n Astronaut\u00a0Kate Rubins<\/a> worked to set up experiment hardware for Transparent Alloys<\/a>, an ESA (European Space Agency) investigation focusing on microstructure evolution by comparing the effects of Earth\u2019s gravity to microgravity, pinpointing the correlation in particle size, growth dynamics, and fluid flow.<\/p>\n Meanwhile, Soichi Noguchi<\/a> of JAXA (Japan Aerospace Exploration Agency) spent time removing and replacing hardware \u2014 the Artificial Vision Unit \u2014 in the station\u2019s cupola, where the crew often spends time observing natural Earth phenomena from their unique vantage approximately 250 miles above.<\/p>\n The crew wrapped up their workday with the Airborne Particulate Monitor<\/a> (APM), installing instrument hardware and taking photo documentation. Air quality in crewed spacecraft is important for astronaut health and comfort, and the APM measures the concentration of both small and large particles in the air. Captured data will eventually be used to create a detailed mapping of the air quality aboard the space station, shedding light on the sources of different air particles and how they behave in this one-of-a-kind laboratory off the planet.<\/p>\n Learn more about station activities by following the\u00a0space station blog<\/a>,\u00a0@space_station<\/a>\u00a0and\u00a0@ISS_Research<\/a>\u00a0on Twitter as well as the\u00a0ISS Facebook<\/a>\u00a0and\u00a0ISS Instagram<\/a>\u00a0accounts.<\/p>\n Get The Details…<\/a><\/p>\n Catherine Williams <\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n","protected":false},"excerpt":{"rendered":" After a weekend that included the 237th spacewalk in support of assembly and maintenance for the International Space Station, featuring spacewalkers and NASA astronauts\u00a0Victor Glover\u00a0and\u00a0Michael Hopkins, the Expedition 64 crew members got back to the business of science, switching out hardware and working around a comprehensive emergency drill on Monday.
