Astronauts Unload Dragon, Prep for Two U.S. Spacewalks

 







ISS - Expedition 65 Mission patch.


June 7, 2021

The SpaceX Cargo Dragon resupply ship is open for business at the International Space Station following its automated docking early Saturday. Now, the Expedition 65 crew turns its attention to a pair of U.S. spacewalks to upgrade the orbiting lab’s power system.

Flight Engineer Megan McArthur and Commander Akihiko Hoshide worked throughout Monday unpacking and activating science experiments delivered Saturday aboard the SpaceX Cargo Dragon. The U.S. space freighter launched from Kennedy Space Center on Thursday carrying over 7,300 pounds of new science, supplies and solar arrays to replenish the orbiting lab.

McArthur started the day transferring research hardware from Dragon to begin work for the Kidney Cells-02 study that seeks to improve treatments for kidney stones and osteoporosis. She followed that up configuring MERLIN and POLAR science freezers containing biological samples inside Dragon.

Hoshide removed mice launched aboard Dragon and placed them inside a habitat in the Kibo laboratory module to study space-caused aging-like symptoms such as bone loss and muscle atrophy.

Kimbrough and Flight Engineer Thomas Pesquet partnered together Monday afternoon readying the U.S. Quest airlock and their U.S. spacesuits for two spacewalks set for June 16 and 20. The experienced spacewalkers, who had two spacewalks together in 2017 during Expedition 50, will work both days to install the first two of six new solar arrays on the space station’s integrated truss structure. Robotics controllers will soon command the Canadarm2 robotic arm to extract the new pair of solar arrays from Dragon’s trunk and stage it in time for the installation spacewalks.

Cosmonauts Oleg Novitskiy and Pyotr Dubrov spent the morning testing satellite navigation gear, studying space exercise and replacing orbital plumbing gear. The duo then wrapped up stowing and inventorying the tools they used during a seven-hour and 19 minute spacewalk on June 2.
