Criticism of the Space Shuttle program (approximately $ per pound adjusting for inflation to 2011). It failed in the goal of achieving reliable access to space, partly due to multi-year interruptions in launches following Shuttle failures. NASA budget pressures caused by the chronically high NASA Space Shuttle program costs have eliminated NASA manned space flight beyond low earth orbit since Apollo, and severely curtailed use of unmanned probes. NASA's promotion of and reliance on the Shuttle slowed domestic commercial expendable launch vehicle (ELV) programs until after the 1986 "Challenger" disaster. "Space Transportation System" (NASA's formal name for the overall Shuttle program) was created to transport crewmembers
Space Shuttle Endeavour Manchester Boulevard Bridge. The space shuttle was mainly carried by four self-propelled robotic dollies throughout the 12 mile journey. However, due to bridge weight restrictions, the space shuttle was moved onto the dolly towed by the Tundra. After it had completely crossed the bridge, the Space Shuttle was returned to the robotic dollies. The footage was later used in a commercial for the 2013 Super Bowl. Having taken longer than expected, "Endeavour" finally reached the Science Center on October 14. The exhibit was opened to the public on October 30, 2012 at the temporary Samuel Oschin Space Shuttle "Endeavour" Display
