<\/a><\/figure>Space agriculture, stem cells, and cargo operations wrapped up the week aboard the International Space Station<\/a>. The Expedition 74<\/a> crew also conducted blood tests and installed a new food processor as a U.S. cargo spacecraft nears the end of its mission.<\/p>\n Launching a spacecraft on Earth packed with enough food for a yearslong crew mission or sending resupply ships to replenish a crew beyond low Earth orbit is prohibitive. Therefore, growing plants aboard a spacecraft is key to sustaining crews on long-duration missions to the Moon, Mars, and beyond. As a result, NASA and its international partners have been exploring growing crops in space to enable crews to feed themselves without support from Earth. NASA flight engineer Chris Williams<\/a> contributed to the ongoing space agriculture research at the end of the week and configured a microscope to observe plant cell division<\/a> in microgravity. Insights may lead to improved methods of growing food in space as well as on lunar and planetary surfaces.<\/p>\n Low Earth orbit may also be the next frontier for biomedical manufacturing as doctors seek to overcome the limitations of gravity on the ground. NASA flight engineer Jessica Meir<\/a> harvested blood stem cells inside the Kibo laboratory module<\/a>\u2019s Life Science Glovebox<\/a> (LSG) that have been growing aboard the orbital outpost since the arrival of a SpaceX Dragon cargo craft on May 17<\/a>. Next, she looked at the density and viability of the live cells using the KERMIT fluorescent microscope<\/a>. Researchers are exploring space-designed cell therapies to treat serious medical conditions such as blood cancers and immune diseases<\/a>.<\/p>\n Dragon is due to depart the International Space Station at 12:05 p.m. EDT on Tuesday, June 16<\/a>, to return the stem cell samples, including several tons of completed science experiments and lab hardware, for analysis on Earth. Live coverage of Dragon\u2019s undocking and departure begins at 11:45 a.m. on NASA+<\/a>.<\/p>\n Williams and Meir also partnered with flight engineers Jack Hathaway<\/a> of NASA and Sophie Adenot of ESA (European Space Agency) packing Dragon with return cargo together throughout Friday. The quartet will intensify their cargo transfers early next week when they begin loading Dragon with sensitive research samples packed inside portable science freezers<\/a> for preservation, retrieval, and analysis on Earth.<\/p>\n Williams and Meir began their Friday shift collecting blood samples for spinning in a centrifuge then stowing in a science freezer<\/a> for future analysis. Hathaway removed a research freezer from inside Kibo\u2019s Life Science Glovebox used the day before to preserve bacteria samples for genetic and chemical analysis<\/a>. Adenot also spent some time assisting Meir during the stem cell operations then tested a new food processor<\/a> in the Columbus laboratory module<\/a> by cooking a Mediterranean dish.<\/p>\n The station\u2019s three cosmonauts, station commander Sergey Kud-Sverchkov and flight engineers Sergei Mikaev and Andrey Fedyaev enjoyed an off-duty day on Friday.<\/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 Powered by WPeMatico<\/a><\/small><\/p>\n Get The Details…<\/a><\/p>\n Mark A.
