Spacewalk Preps, Science, and Cargo Work Kick Off New Year
Expedition 72 is beginning the New Year preparing for an upcoming spacewalk to service science hardware and install communications gear. The International Space Station residents also conducted space agriculture and worked on cargo duties at the beginning of the week.
Two NASA astronauts are scheduled to exit the orbital outpost’s Quest airlock this month for a spacewalk to checkout a pair of astrophysics experiments attached to the outside of the space station, as well as conduct other tasks. First, the NICER X-ray telescope will be serviced with a patch to prevent unwanted sunlight from entering the instrument and corrupting research data. Next, the Alpha Magnetic Spectrometer will be prepared for future upgrades tasked for spacewalks planned later this year.
The four astronauts aboard the station including Commander Suni Williams and Fight Engineers Nick Hague, Don Pettit, and Butch Wilmore worked throughout Monday preparing for the science maintenance spacewalk. These preps included collecting and organizing spacewalking tools inside Quest and practicing installing the jetpacks on spacesuits a spacewalker would use to maneuver back to safety in the unlikely event they became untethered from the space station. The quartet also reviewed the procedures planned for the first spacewalk of 2025.
Pettit and Wilmore rounded out their day conducting science and transferring cargo. Pettit worked in the Columbus laboratory module thinning Red Romaine lettuce seedlings to learn how to grow food crops on space missions. Wilmore transferred cargo in and out of the Cygnus cargo craft that has been berthed to the Unity module since Aug. 6, 2024.
The three cosmonauts from Roscosmos spent their shift in the Roscosmos segment of the orbiting lab performing a variety of science and maintenance tasks. Flight Engineer Aleksandr Gorbunov photographed microorganisms being incubated for a space biology study. Flight Engineer Ivan Vagner spent his day pumping water and transferring cargo from inside the Progress 90 resupply ship that docked to the Poisk module on Nov. 23. Flight Engineer Alexey Ovchinin inventoried hardware inside the Zarya, Zvezda, Nauka, and Poisk modules.
