Some Moon rocks from the Apollo missions are displayed in museums, and a few allow visitors to touch them. One of these, called the "Touch Rock", is displayed in the Smithsonian National Air and Space Museum in Washington, D.C. The idea of touchable Moon rocks at a museum was suggested by Apollo scientist Farouk El-Baz, inspired his childhood pilgimage to Mecca where he touched the Black Stone (which in Islam is believed to be sent down from the heavens).
