It is maintained by the Astronauts Memorial Foundation (AMF), whose offices are located in the NASA Center for Space Education next door to the Visitor Complex.The memorial was designed in 1987 by Holt Hinshaw Pfau Jones, and dedicated on May 9, 1991, to remember the lives of the men and women who have died in the various space programs of the United States, particularly those of NASA.In addition to 20 NASA career astronauts, the memorial includes the names of a U.S. Air Force X-15 test pilot, a U.S. Air Force officer who died while training for a then-classified military space program, a civilian spaceflight participant who died in the Challenger disaster, and an Israeli astronaut who was killed in the Columbia disaster.[1] The first private astronaut to be added to the wall was Scaled Composites pilot Michael T. Alsbury, who died in the crash of SpaceShipTwo VSS Enterprise on October 31, 2014.[2] Estimated cost of repairs was around $700,000, and the Astronauts Memorial Foundation unanimously decided the money would be better spent on educational programs instead.On September 4, 1986, Alan Helman and Leland McKee were presented a resolution by Governor Bob Graham and the Florida cabinet fully endorsing the efforts of The Astronauts Memorial Foundation.
