space agency, this vehicle could carry astronauts and payloads into low Earth orbit, perform in-space operations. Operated from 1977 to 2011 by NASA, 1 the U.S. It was built as a replacement for space shuttle Challenger, which had a fatal incident after launch on Jan. The Space Shuttle orbiter is the spaceplane component of the Space Shuttle, a partially reusable orbital spacecraft system that was part of the discontinued Space Shuttle program. Lights out on Endeavour: The California Science Center is closing its 11-year exhibit of the space shuttle Endeavour on Dec. Project officials say this will be the world’s only display of an authentic, “ready-to-launch” space shuttle system. Endeavour was the fifth orbiter built and it first arrived at NASA’s Kennedy Space Center in Florida on May 7, 1991, atop the NASA 747. The prototype Enterprise is on exhibit at the Intrepid Museum in New York and the Shuttle Carrier Aircraft that flew Endeavour to Los Angeles is open for tours at Space Center Houston in Texas. The six, triple-friction pendulum base isolators located beneath the space shuttle will allow for up to 30 inches of movement in a seismic event, according to Arup. To ensure stability and safety in an earthquake, the engineering team worked with ex-Boeing engineers from the space shuttle program and used a program called LS Dyna to run the structure through multiple earthquake scenarios. The vast panels will also reflect sunlight, creating a bright new star. “The complication is that the exhibit is heavy and there are earthquakes in LA, so the ground is going to shake quite a bit and you have a 500,000-pound, 180-foot-tall exhibit moving around, experiencing lots of different forces and displacements, and the base it sits on has to be strong enough to keep it from rotating over,” she says. At Kennedy Space Center in Florida the Space Shuttle Endeavour stands ready for launch. The seismic isolator pad is about 8 ft thick, 45 ft wide and 75 ft long and is built to support the entire weight of the 500,000-lb completed exhibit. When complete, the exhibit will stand 200 ft tall and weigh approximately 500,000 lb.Īmie Nulman, associate principal with Arup, says the most challenging aspect of this part of the project was forming the base that the afts sit on.
