<\/a>The orbiting lab\u2019s three newest residents are beginning their science and maintenance tasks after several days of International Space Station<\/a> orientation and familiarization activities. In the meantime, three Expedition 67<\/a> crew members are less than a week away from ending their mission and returning to Earth after living and working in space for six months.<\/p>\n NASA Flight Engineer Frank Rubio<\/a> kicked off his first full week on the station with a physics study that uses artificial intelligence to adapt materials manufacturing to the vacuum of space. He began Monday morning setting up the Microgravity Science Glovebox<\/a> and servicing components inside the research device. Rubio then spent the afternoon preparing complex glass samples inside the glovebox for future experiment runs. The Intelligent Glass Optics<\/a> investigation may help advance Earth and space-based industries including communications, aerospace, medicine, and astronomy.<\/p>\n Rubio\u2019s cosmonaut crewmates, Flight Engineers Sergey Prokopyev<\/a> and Dmitri Petelin<\/a>, who rode with him to the station last week<\/a> began their week with a variety of research and maintenance activities. Prokopyev started his day on water transfer activities before helping pack a Soyuz crew ship for its return to Earth on Thursday. Petelin also worked on water transfers throughout the day and explored how spaceflight affects the human immune system.<\/p>\n The station\u2019s population will go back to seven crew members on Thursday after three cosmonauts undock in their Soyuz MS-21<\/a> crew vehicle and parachute to a landing in Kazakhstan. Station Commander Oleg Artemyev<\/a> will board the Soyuz crew ship with Flight Engineers Denis Matveev<\/a> and Sergey Korsakov<\/a> and undock from the Prichal module<\/a> at 3:34 a.m. EDT on Thursday. The trio will parachute to a landing in the steppe of Kazakhstan less than three-and-a-half hours later. NASA TV<\/a> will broadcast the undocking and landing activities live on the agency\u2019s app and website beginning at 3:15 a.m.<\/p>\n Artemyev will hand over station leadership responsibilities to ESA (European Space Agency) astronaut Samantha Cristoforetti<\/a> the day before he departs. The traditional Change of Command ceremony will be seen live on NASA TV starting at 9:35 a.m. on Wednesday.<\/p>\n The space station\u2019s four other flight engineers stayed busy throughout Monday on a host of research activities including biology, botany, and combustion. NASA astronaut Jessica Watkins<\/a> wore a specialized vest and headband beginning a two-day session to record her health functions for the Bio-Monitor<\/a> study. NASA astronaut Bob Hines<\/a> nourished and inspected plants growing for the XROOTS<\/a> space agriculture study. Flight Engineer Kjell Lindgren<\/a> of NASA set up the Confocal space microscope<\/a> to study how microgravity affects the nervous system<\/a>. Finally, Cristoforetti rerouted cables for a combustion research device to ensure its igniter can move correctly.<\/p>\n Get The Details…<\/a><\/p>\n Mark Garcia <\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n","protected":false},"excerpt":{"rendered":" The orbiting lab\u2019s three newest residents are beginning their science and maintenance tasks after several days of International Space Station orientation and familiarization activities.
