ISS - Expedition 65 Mission patch.
June 10, 2021
Mission controllers will command the Canadarm2 robotic arm to remove a new pair of solar arrays from the SpaceX Cargo Dragon resupply ship tonight. Four Expedition 65 astronauts are also training for robotics activities to support two spacewalks scheduled to begin next week.
Packed inside the unpressurized segment of the Cargo Dragon, also known as its trunk, is a pair of unique solar arrays that will soon be attached to the International Space Station’s Port-6 truss structure. Also called iROSA, or ISS Roll Out Solar Arrays, they will be extracted tonight from Dragon’s trunk by robotics controllers remotely commanding the Canadarm2. It will be staged on the truss structure where two spacewalkers will install it on the station starting next week.

In the meantime, Flight Engineers Shane Kimbrough and Thomas Pesquet are preparing for those two installation spacewalks planned for June 16 and 20. The duo joined fellow flight engineers Mark Vande Hei and Megan McArthur on Thursday afternoon for computerized training to prepare for the robotics activities necessary to support the solar array installation work.
Kimbrough and Pesquet this week have been inspecting their spacesuits, organizing their tools and readying the U.S. Quest airlock where they will stage both spacewalks. They will set their spacesuit batteries to battery power at 8 a.m. EDT on both days signifying the start of their spacewalk. NASA TV will begin its live coverage of both spacewalks at 6:30 a.m.
Science is still ongoing aboard the orbital lab as the astronauts and mission controllers get ready for the two spacewalks.

Commander Akihiko Hoshide and Pesquet took turns wearing a virtual reality headset and clicking a trackball for the Time Perception experiment. Kimbrough inventoried medical supplies and photographed cotton plants growing for the TICTOC space botany study. McArthur worked on a pharmaceutical freeze-drying study while Vande Hei loaded a CubeSat deployer for upcoming satellite deployments.
In the Russian segment of the orbital lab, Flight Engineer Oleg Novitskiy checked on Soyuz MS-18 crew ship and ISS Progress 77 resupply ship gear today. Flight Engineer Pyotr Dubrov assisted with the Soyuz work and worked throughout the day on Russian life support and computer maintenance.
