<\/a><\/figure>The Expedition 74<\/a> crew members packed a SpaceX Dragon cargo spacecraft on Monday with sensitive science experiments and lab hardware for return to Earth. The orbital residents also configured spacewalking tools and conducted cardiac research to kick off the week aboard the International Space Station<\/a>.<\/p>\n A SpaceX Dragon cargo spacecraft is scheduled to undock from the Harmony module<\/a>\u2019s forward port at 12:05 p.m. EDT on Tuesday<\/a> ending its stay at the orbital laboratory that began on April 17<\/a>. NASA+ will begin its broadcast of Dragon\u2019s undocking and departure at 11:45 a.m<\/a>. Dragon\u2019s parachute-assisted splashdown in the Pacific Ocean off the coast of southern California the following day will not be televised.<\/p>\n The astronauts are partnering together transferring portable science freezers<\/a> loaded with critical research samples and packing lab equipment into Dragon following a month of intense research into a variety of space-designed therapies to protect human health. The freezers house the results of investigations into stem cell manufacturing<\/a>, cartilage tissue printing<\/a>, and more to treat a range of conditions from blood diseases, cancers, and cartilage injuries. Doctors on the ground will analyze the preserved samples to gain advanced health insights unobtainable in Earth\u2019s gravity environment.<\/p>\n NASA flight engineers Chris Williams<\/a> and Jack Hathaway<\/a> started the cargo work early Monday packing and securing station hardware inside Dragon for the ride back to Earth. Next, flight engineer Sophie Adenot of ESA (European Space Agency) installed the sample-packed freezers in Dragon where they will stay powered on preserving the biomedical specimens for retrieval on the ground. Finally, NASA flight engineer Jessica Meir<\/a> capped off Monday\u2019s shift with more scientific transfers then cleaned and inspected hatch seals on Harmony\u2019s port where Dragon is docked.<\/p>\n Meanwhile, preparations continue for a spacewalk planned for June 30<\/a> to replace a wrist joint on the Canadarm2 robotic arm<\/a>. Adenot began her shift in the Quest airlock<\/a> charging lithium-ion batteries that power spacesuit glove heaters, helmet cameras, and pistol grip tools. Williams and Meir joined each other during a break in their Dragon packing and inspected tethers that secure astronauts to the orbiting lab during spacewalks.<\/p>\n Station commander Sergey Kud-Sverchkov and flight engineer Sergei Mikaev, both from Roscosmos, took turns wearing a series of arm, wrist, and finger cuffs measuring how living in space affects their blood pressure. Next, Kud-Sverchkov attached electrocardiogram sensors to his chest that will monitor his cardiac activity for 24 hours. Mikaev turned his attention to Earth observations, pointed a camera out a station window, and photographed landmarks across the Pacific Ocean including islands and volcanos.<\/p>\n Flight engineer Andrey Fedyaev began his shift transferring fluids and disinfecting tanks throughout the station\u2019s Roscosmos segment. Fedyaev wrapped up his shift working on ventilation system maintenance and checking station lighting conditions and illumination levels.<\/p>\n Learn more about station activities by following the <\/em>space station blog<\/em><\/a>, <\/em>@space_station<\/em><\/a>on X, as well as the <\/em>ISS Facebook<\/em><\/a> and <\/em>ISS Instagram<\/em><\/a> accounts.<\/em><\/p>\n Get the latest from NASA delivered every week. <\/em>Subscribe here<\/em><\/a>.<\/em><\/p>\n<\/p>\n Powered by WPeMatico<\/a><\/small><\/p>\n Get The Details…<\/a><\/p>\n Mark A.
