In Orbiter Processing Facility-2 (OPF-2) at NASA’s Kennedy Space Center in Florida, work begins to remove space shuttle Atlantis’ forward reaction control system. The system provided maneuvering capabilities to the spacecraft during its missions. Atlantis glided to a landing, July 21, 2011, at Kennedy Space Center’s Shuttle Landing Facility, completing NASA’s final space shuttle mission, STS-135. The shuttle is in OPF-2 being decommissioned and prepared for eventual display at the Kennedy Space Center Visitor Complex in Florida. Photo credit: Kim Shiflett
