Four of the six Expedition 61 crewmembers are relaxing today before ramping up final preparations for Friday’s spacewalk. The two cosmonauts maintained their normal schedule of Russian science and maintenance activities.
Morgan and Koch will not only ready their U.S. spacesuits for Friday’s spacewalk, they will also research cancer therapies and microbial DNA sequencing. Parmitano will assist the duo with the spacesuit preparations and help Meir with an aerobic fitness evaluation.
The two cosmonauts stayed busy today in the Russian segment of the orbiting lab. Flight Engineers Alexander Skvortsov and Oleg Skripochka split their time between microgravity research and station maintenance. Skvortsov explored how leg veins adapt to weightlessness before checking on station air conditioning and smoke detectors. Skripochka explored pain sensitivity in space and shared a moment with ham radio operators on the ground for an educational opportunity.
Expedition 60 Commander Alexey Ovchinin and NASA Flight Engineer Nick Hague are in their final week aboard the orbiting lab. The homebound residents are packing up their Soyuz MS-12 crew ship and handing over their duties to the crewmates staying in space.
They will undock Thursday from the Rassvet module at 3:36 a.m. EDT along with spaceflight participant Hazzaa Ali Almansoori. The trio will parachute to a landing in Kazakhstan at 7 a.m. (5 p.m. Kazakhstan time). All three returning crewmates reviewed their undocking and landing procedures today.
Morgan then explored increasing the purity of protein crystals in space to improve pharmaceutical and biochemistry research. Veteran cosmonaut Alexander Skvortsov conducted his own biochemistry research in the Russian segment of the space lab studying how the microgravity environment impacts enzymes in the human body.
New Expedition 61 crewmates Jessica Meir of NASA and Oleg Skripochka of Roscosmos continue settling in for their 189-day mission inside the orbiting lab. Meir reviewed Canadarm2 robotics procedures today to support upcoming spacewalks. She wrapped up the day observing protein crystals to support cancer research. Skripochka tested a specialized suit that counteracts the headward flow of fluids in astronauts due to microgravity. He finally checked out the Magnetic 3D Printer that explores the benefits of printing organic tissue in space.
Japan’s eighth station resupply ship, also known as the Kounotori, is open for business and Parmitano and NASA astronaut Christina Koch are unloading its cargo and new science hardware today. Kounotori is due for a month-long stay attached to the Harmony module for internal and external cargo operations. Ground controllers will be commanding the Canadarm2 to remove new lithium-ion batteries delivered on Kounotori’s external pallets. The robotics work will be setting up a series of power upgrade spacewalks planned for October.
