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.

KENNEDY SPACE CENTER, FLA. -- Following its arrival at Kennedy Space Center, The node structural test article (STA) begins its move to a storage facility. The super Guppy transport aircraft carried Node STA to KSC's Shuttle Landing Facility from Marshall Space Flight Center in Huntsville, Ala. An exact replica of the Unity Node on the International Space Station, the node STA was used at MSFC for testing and validation purposes. The Unity Node is the pressurized element that connects the other ISS pressurized modules together and was the first U.S. element to launch.

KENNEDY SPACE CENTER, FLA. -- A shuttle training aircraft, or STA, takes off from Kennedy Space Center's Shuttle Landing Facility at dusk. The STA is being used for practice flights by space shuttle Atlantis STS-122 Commander Steve Frick and Pilot Alan Poindexter. The STA is a Grumman American Aviation-built Gulf Stream II jet that was modified to simulate an orbiter's cockpit, motion and visual cues, and handling qualities. In flight, the STA duplicates the orbiter's atmospheric descent trajectory from approximately 35,000 feet altitude to landing on a runway. Because the orbiter is unpowered during re-entry and landing, its high-speed glide must be perfectly executed the first time. The training is part of terminal countdown demonstration test, or TCDT, activities. The TCDT provides astronauts and ground crews with equipment familiarization, emergency egress training and a simulated launch countdown. On mission STS-122, Atlantis will deliver the European Space Agency's Columbus module to the International Space Station. Columbus is a multifunctional, pressurized laboratory that will be permanently attached to U.S. Node 2, called Harmony, and will expand the research facilities aboard the station. Launch is targeted for Dec. 6. Photo credit: NASA/Kim Shiflett
