NASA Flight Engineer Kjell Lindgren set up Astrobee’s free-flying robots for a student robotics competition. For the competition, students write software to control one of the station’s Astrobee free-flying robots. Finalists have their code downloaded by NASA to the Astrobee platform and observe its performance.
NASA Flight Engineer Bob Hines made progress preparing and photographing sample returns for the Genes in Space-9 study, which evaluates how cell-free technology could be used in microgravity. The technology may provide a portable, low-resource, and low-cost tool with medical and monitoring applications for future space missions.
NASA Flight Engineer Jessica Watkins continued to purge and take samples of carbon dioxide from the Thermal Amine Scrubber, which tests a technology for removing carbon dioxide from the station’s air. ESA (European Space Agency) Flight Engineer Samantha Cristoforetti spent time talking with students about life in space and other space-related topics. Watkins and Cristoforetti worked together to transfer cargo from the SpaceX CRS-25 Dragon spacecraft.
In the Russian segment of the station, Oleg Artemyev of Roscosmos and Cosmonaut Denis Matveev were tasked with locating, photographing, and storing equipment and tools during a meeting with specialists. Cosmonaut Sergey Korsakov spent time replacing a carbon monoxide filter and sensor a part of a gas analyzer.
Four Expedition 67 crew members slept in on Friday following a spacewalk the day before at the International Space Station. The other three orbital residents wrapped up the workweek researching a variety of space phenomena, unpacking a U.S. cargo ship, and maintaining orbital lab systems.
Artemyev and Cristoforetti woke up late on Friday and spent the rest of the day cleaning their Russian Orlan spacesuits and inspecting spacewalk tools and tethers. Cosmonauts Denis Matveev and Sergey Korsakov also slept in on Friday having monitored the spacewalkers and assisted the duo in and out of their spacesuits the day before. The pair also helped out with the post-spacewalk activities returning the Poisk airlock to its normal configuration and re-opening the hatch to the ISS Progress 80 cargo craft.
The station’s three NASA Flight Engineers including Bob Hines, Jessica Watkins, and Kjell Lindgren, worked a normal shift on Friday and wrapped up their workweek focusing on an array of science and maintenance operations.
Life science, robotics and space construction kept the Expedition 66 crew busy aboard the International Space Station on Wednesday. The orbital residents also worked on spacesuits and inspected a Russian module.
Eye checks continued on the orbiting lab with NASA astronaut Thomas Marshburn taking charge as crew medical officer during the afternoon. The three-time station astronaut used medical imaging gear, or optical coherence tomography, to scan the eyes and retinas of NASA Flight Engineers Kayla Barron and Raja Chari.
Marshburn began his day studying how to produce and maintain nutrients during long-term space missions. Chari later worked on communications components inside a pair of U.S. spacesuits. Barron started her morning cleaning the Cell Biology Experiment Facility, an incubator with an artificial gravity generator.
NASA Flight Engineer Mark Vande Hei set up the free-flying Astrobee robotic assistants and tested an autonomous rendezvous algorithm for the ROAM technology demonstration. ESA (European Space Agency) astronaut Matthias Maurer resumed the Concrete Hardening experiment studying potential lunar and planetary construction techniques.
