A flatbed truck, carrying the node structural test article (STA), is on its way to the Launch and Landing Facility from the Space Station Processing Facility (SSPF) at NASA’s Kennedy Space Center in Florida on July 20, 2020. In view is the iconic Vehicle Assembly Building. The Node STA was used to prove the manufacturing processes and procedures were robust for extended human spaceflight. Those same processes and procedures were then used to build Node 1, which Kennedy Center Director Bob Cabana flew to the space station on STS 88. NASA has stored the node STA in the SSPF, and it is moving to a new location to allow for more space in the facility’s high bay to support the agency’s space exploration and commercialization efforts in low-Earth orbit.

The spacecraft and cargo module will begin resupply and return services missions to the space station in late 2021.

A truck carrying the cargo logistics module for Sierra Nevada Corporation’s Dream Chaser, the company’s reusable spaceplane, arrives at the Space Station Processing Facility high bay entrance at NASA’s Kennedy Space Center in Florida on Aug. 27, 2019.

Nanoracks technicians work on the NanoRacks Bishop Airlock inside the Space Station Processing Facility at NASA's Kennedy Space Center in Florida on Sept. 29, 2020. The next-generation Nanoracks payload facility is being prepared for its flight to the International Space Station on SpaceX’s 21st commercial resupply services mission (CRS-21) to the International Space Station. The Bishop Airlock is the first commercially funded airlock for the space station. It will provide payload hosting, robotics testing, satellite deployment, serve as an outside toolbox for station crew spacewalks, and more. CRS-21 is scheduled to launch on a SpaceX Falcon 9 rocket no earlier than November from Launch Complex 39A at Kennedy Space Center.
