The newly arrived and soon-to-depart crew members of Expedition 73 prepared for what is to come next during this, their final week all together aboard the International Space Station, Dec. 1-5, 2025.<\/p>\n

Orbital observation<\/p>\n

JAXA<\/a> astronaut Kimiya Yui is fond of photographing his home nation of Japan from his vantage point aboard the International Space Station<\/a>. Thursday (Dec. 4) was no different.<\/p>\n

<\/p>\n

“Last night, I went to bed early and woke up once in the middle of the night to film a video of the Japanese archipelago,” Yui posted to social media<\/a>. “Even from space, it looked very cold.”<\/p>\n

“There were many areas where it seemed to be snowing or places where it had snowed afterward, and while it looked beautiful from space, I became a little worried when I thought about all of you,” he wrote.<\/p>\n

Among the research that was conducted by the Expedition 73 crew aboard the space station this week was:<\/p>\n

CIPHER<\/strong> \u2014 Zena Cardman and Jonny Kim of NASA collected samples of Cardman’s blood, tested her cognition and measured her exercise, all as activities under the CIPHER human research study tracking astronauts’ health before, during and after a spaceflight. Afterward, Cardman used a centrifuge to prepare them for being placed inside a science freezer for future analysis.<\/p>\n

Astrobee<\/strong> \u2014 Scientists on Earth<\/a>, working with astronauts on the space station like Kim, assessed robotic free-flying assistants called “Astrobee<\/a>” to enable astronauts to conduct more research.<\/p>\n

Station keeping<\/p>\n

The Expedition 73 crew also devoted time to maintaining the space station’s systems, including:<\/p>\n

New Crew Member Orientation<\/strong> \u2014 Having just arrived at the space station the week before, NASA astronaut Chris Williams attended an orientation session, of sorts, as fellow NASA astronaut Mike Fincke and Kimiya Yui of JAXA took turns bringing Williams up to speed about life on orbit. Fincke and Yui familiarized Williams with space station hardware, operations and systems.<\/p>\n

‘Closet’ inventory <\/strong>\u2014 Oleg Platonov, a flight engineer with the Russian space agency Roscosmos<\/a>, spent the first part of his shift documenting the location and amount of clothing and towels remaining in the Russian segment of the space station.<\/p>\n

Zero Boil-Off Tank Noncondensables<\/strong> \u2014 Flight Engineer Mike Fincke changed out the cameras inside a microgravity science glovebox to photograph how cryogenic fluids behave in microgravity<\/a> to improve the design of spacecraft fuel tanks.<\/p>\n

As part of their work maintaining the systems aboard the International Space Station, NASA astronauts Jonny Kim and Chris Williams spent this week cleaning and inspecting the European Exploration Exercise Device (E4D) after its installation in the European Space Agency<\/a>‘s (ESA) Columbus laboratory.<\/p>\n

According to NASA, the E4D is being tested for its ability to provide bicycling, rowing and resistance exercises to protect crew members’ muscles, bones and heart health in microgravity.<\/p>\n

By the numbers<\/p>\n

As of Friday (Dec. 5), there are 10 people<\/strong> aboard the International Space Station: Expedition 73 commander Sergey Ryzhikov and Oleg Platonov, Sergey Kud-Sverchkov, Sergey Mikaev and Alexey Zubritsky of Roscosmos<\/a>; NASA astronauts Zena Cardman, Mike Fincke, Jonny Kim and Chris Williams and JAXA (the Japan Aerospace Exploration Agency) astronaut Kimiya Yui, all flight engineers.<\/p>\n

There are three docked crew spacecraft<\/strong>: SpaceX<\/a>‘s Dragon “Endeavour” attached to the space-facing port of the Harmony module, Roscosmos’ Soyuz MS-27 attached to the Earth-facing port of the Prichal node and Soyuz MS-28 attached to the Earth-facing port of the Rassvet module.<\/p>\n

There are four cargo spacecraft<\/strong>: Roscosmos’ Progress MS-31 (92P) docked to the space-facing port of the Poisk module, Progress MS-32 (93P) attached to the aft port of the Zvezda service module, Northrop Grumman’s Cygnus XL, the S.S. William C. “Willie” McCool, berthed to the Earth-facing common berthing mechanism (CBM) on the Unity node and Japan’s HTV-X1<\/a> attached to the Earth-facing CBM on the Harmony node.<\/p>\n

As of Friday, the space station has been continuously crewed for 25 years, 1 month and 3 days<\/strong>.<\/p>\n","protected":false},"excerpt":{"rendered":"The newly arrived and soon-to-depart crew members of Expedition 73 prepared for what is to come next during…\n","protected":false},"author":2,"featured_media":615033,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[3844],"tags":[70,413,16,15],"class_list":{"0":"post-615032","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-space","8":"tag-science","9":"tag-space","10":"tag-uk","11":"tag-united-kingdom"},"share_on_mastodon":{"url":"https:\/\/pubeurope.com\/@uk\/115670279808382097","error":""},"_links":{"self":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/615032","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/comments?post=615032"}],"version-history":[{"count":0,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/posts\/615032\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media\/615033"}],"wp:attachment":[{"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/media?parent=615032"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/categories?post=615032"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.europesays.com\/uk\/wp-json\/wp\/v2\/tags?post=615032"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
