<\/a>Crew health and space biology were the top research objectives for the Expedition 70<\/a> crew at the beginning of the week. The International Space Station<\/a> residents also had their hands full with a host of standard lab maintenance tasks. Meanwhile, the SpaceX Dragon cargo spacecraft looks to Wednesday at the earliest for its departure.<\/p>\n Observing the effects of weightlessness on a variety of life forms including humans is a priority for doctors and scientists as NASA and its international partners plan longer missions farther out into space. Researchers are learning how everything from the tiniest organisms, space-grown vegetables, to astronauts adapt and survive in the harsh environment of microgravity.<\/p>\n NASA Flight Engineer Jasmin Moghbeli<\/a> kicked off her day strapping on the Bio-Monitor<\/a> vest and headband to test their ability to comfortably monitor an astronaut\u2019s health throughout the day. The wearables contain a data unit recording a crew member\u2019s cardiovascular fitness for the Space Health<\/a> investigation. She then spent the afternoon treating cell samples inside the Kibo laboratory module<\/a>\u2019s Life Science Glovebox<\/a> for the Space AGE<\/a> health study to learn more about the biology of aging and its effects on disease mechanisms.<\/p>\n A pair of CubeSats were deployed outside the orbital outpost today to explore voice and imagery transmissions<\/a> and test future planetary probe technologies<\/a>. Flight Engineer Satoshi Furukawa<\/a> from JAXA (Japan Aerospace Exploration Agency) pointed his camera outside the Kibo lab and photographed the two small satellite deployments. Afterward, the JAXA astronaut serviced optical hardware to support a regenerative medicine<\/a> experiment. Finally, Furukawa readied the SAFFIRE-VI<\/a> fire safety experiment that will be conducted remotely aboard the Cygnus space freighter<\/a> after it departs the space station.<\/p>\n Astronauts Loral O\u2019Hara<\/a> and Andreas Mogensen<\/a> started Monday morning stowing spacewalking tools in the Quest airlock<\/a>. The duo then split up as O\u2019Hara tested a VHF antenna and inspected the Harmony module<\/a>\u2019s crew quarters. Mogensen from ESA (European Space Agency) installed air sensors in Harmony then inspected hoses inside the COLBERT treadmill<\/a>.<\/p>\n Cosmonauts Oleg Kononenko and Konstantin Borisov worked in the Nauka science module<\/a> checking and photographing eggs packed inside a centrifuge for a Roscosmos biology study. Flight Engineer Nikolai Chub spent his day working on life support systems inside the Zarya<\/a> and Zvezda<\/a> modules.<\/p>\n NASA and SpaceX continue to target no earlier than 5:05 p.m. EST Wednesday, Dec. 20, for\u00a0the undocking of\u00a0the company\u2019s 29th Dragon commercial resupply services mission<\/a>\u00a0from the International Space Station.<\/p>\n Coverage of Dragon\u2019s departure Wednesday will begin at 4:45 p.m. on the NASA+ streaming service via\u00a0the web<\/a>\u00a0or the\u00a0NASA app<\/a>. Coverage also will air live on NASA Television,\u00a0YouTube<\/a>, and on the agency\u2019s\u00a0website<\/a>. Learn how to\u00a0stream NASA TV<\/a>\u00a0through a variety of platforms including social media.<\/p>\n Additional undock and return opportunities also are being considered as joint teams continue to work to identify the best autonomous undocking and return weather conditions as a cold front passes through the splashdown zones off the coast of Florida.<\/p>\n More updates will be made following the next weather review about 24 hours prior to Dragon undocking from the space station.<\/p>\n Learn more about station activities by following the\u00a0space station blog<\/a>,\u00a0@space_station<\/a>\u00a0and\u00a0@ISS_Research<\/a>\u00a0on X, as well as the\u00a0ISS Facebook<\/a>\u00a0and\u00a0ISS Instagram<\/a>\u00a0accounts.<\/p>\n Get weekly video highlights at:\u00a0https:\/\/roundupreads.jsc.nasa.gov\/videoupdate\/<\/a><\/p>\n Get the latest from NASA delivered every week.
