Expedition 72: New Crew Members at Work & More | International Space Station
NASA astronaut and Expedition 72 Flight Engineer Nichole Ayers inserts a cryogenic storage unit, called a dewar, containing blood samples collected from a crew member into a science freezer for preservation and later analysis. The Minus Eighty-Degree Laboratory Freezer for International Space Station, or MELFI, is a research freezer that maintains experiment samples at ultra-cold temperatures in microgravity.
NASA astronaut Nichole Ayers: "More science! After completing a blood draw (we are our own phlebotomists up here), we spun the tubes in a centrifuge and then put them in the MELFI (Minus Eighty Degree Laboratory Freezer) for later return to the ground.
This study is looking at bone structure pre- and post-mission, as well as bone markers in the blood to help build a digital twin model that can aid in predictions of future bone evolution."
NASA astronaut and Expedition 72 Flight Engineer Nichole Ayers works inside the International Space Station's Kibo laboratory module loading software onto an Astrobee robotic free-flyer. The software is part of a technology investigation demonstrating an adaptor for docking and close approach sensing to connect both active and passive objects in space. Results may enable applications, such as satellite servicing, orbital refueling, spacecraft repair and upgrade, and in-orbit manufacturing.
Japan Aerospace Exploration Agency (JAXA) astronaut and Expedition 72 Flight Engineer Takuya Onishi is pictured inside the cargo-packed vestibule in between the International Space Station and the SpaceX Dragon crew spacecraft. Onishi was continuing to unpack cargo stowed inside Dragon that had docked to the orbital outpost the day before with him and fellow SpaceX Crew-9 members Anne McClain and Nichole Ayers of NASA, and Kirill Peskov of Roscosmos aboard.
NASA astronaut and Expedition 72 Flight Engineer Anne McClain works on hardware maintenance tasks inside the International Space Station's Kibo laboratory module. Behind McClain is Kibo's airlock where experiment hardware, such as external exposure investigations and CubeSats are staged before being placed outside the orbiting lab into the vacuum of space.
The Russian Soyuz MS-26 spacecraft that launched NASA astronaut Don Pettit and Roscosmos cosmonauts Alexey Ovchinin and Ivan Vagner to the International Space Station is pictured docked to the Rassvet module. The orbiting lab was soaring 260 miles above Turkmenistan near the Caspian Sea.
