The exhibit also includes a life sized replica of the Hubble Space Telescope, the Shuttle program's astrovan, Dr. Maxime Faget’s Shuttle prototype from 1969, a large-scale slide mimicking the 22 degree slope of a Space Shuttle when landing, numerous astronaut training and Shuttle simulators, and other displays about life in space. On the ground level is the "Forever Remembered" exhibit, commemorating the 14 astronauts lost in both Space Shuttle "Challenger" and Space Shuttle "Columbia" disasters. Forever Remembered includes personal artifacts from the astronauts, two recovered pieces of the Shuttles, footage of the physical and emotional recovery, and the return to flight.
