ISS Daily Summary Report – 7/21/2021

Crew Dragon Endeavour Port Relocation: Today, NASA astronauts Shane Kimbrough and Megan McArthur, ESA astronaut Thomas Pesquet, and JAXA astronaut Akihiko Hoshide, undocked Crew Dragon Endeavour from the Node 2 Forward International Docking Adapter (IDA) at 5:45 AM CT and docked to the Node 2 Zenith IDA at 6:36 AM CT. This relocation cleared the Node 2 Forward IDA for Starliner Orbital Flight Test 2 (OFT-2) docking planned for Saturday, July 31st. 


ISS Amateur (HAM) Radio: The crew initiated a HAM Radio contact with SpaceKids Global, Winter Park, FL. ISS Ham Radio provides opportunities to engage and educate students, teachers, parents and other members of the community in science, technology, engineering and math by providing a means to communicate between astronauts and the ground HAM radio units.


Crew Dragon Post-Relocation Configurations: The crew completed several tasks following the completion of the Endeavour port relocation to configure the vehicle for quiescent operations. First, the crew transferred ballast materials and stowage lockers from Crew Dragon to the ISS. Next, the crew transferred emergency hardware from the ISS to Crew Dragon and installed Emergency Air Supply equipment. Finally, the crew relocated the Space Station Computers (SSC) used in the Cupola for ISS crew monitoring of the relocation to the LAB.

Resupply Air Tank Re-pressurization: Today, the remaining two Resupply Air Tanks that were delivered on Cargo Dragon SpaceX-22 were vented in the PMM in order to re-pressurize the ISS internal volume.
