NASA Kennedy Space Center Director Bob Cabana, far right, serves as moderator for the “Apollo Heroes Panel Discussion” in the IMAX Theater at the Kennedy Space Center Visitor Complex in Florida on July 16, 2019. Panelists are, from left, JoAnn Morgan, the only woman on console in the Launch Control Center for Apollo 11 launch countdown activities; Bob Sieck, Apollo-era launch team member and former space shuttle launch director; and Harrison Schmitt, Apollo 17 astronaut and moonwalker. The panel discussion is one of several events at the visitor complex to honor the 50th anniversary of NASA’s Saturn V/Apollo 11 launch and landing on the Moon.

Legendary characters used the power of mythology to fly through the heavens. About 200 BC, a Greek inventor known as Hero of Alexandria came up with a new invention that depended on the mechanical interaction of heat and water. He invented a rocket-like device called an aeolipile. It used steam for propulsion. Hero mounted a sphere on top of a water kettle. A fire below the kettle turned the water into steam, and the gas traveled through the pipes to the sphere. Two L-shaped tubes on opposite sides of the sphere allowed the gas to escape, and in doing so gave a thrust to the sphere that caused it to rotate.

The Heroes and Legends attraction at the Kennedy Space Center Visitor Complex honors what it takes to be a hero. In the center of this display are models of rockets that played key roles in the history of NASA's efforts to explore space. The new facility looks back to the pioneering efforts of Mercury, Gemini and Apollo. It sets the stage by providing the background and context for space exploration and the legendary men and women who pioneered the nation's journey into space.

Inside the Heroes and Legends attraction at the Kennedy Space Center Visitor Complex, the Sigma 7 Mercury spacecraft in this exhibit was piloted by astronaut Wally Schirra during his six-orbit mission on Oct. 3, 1962. For display purposes, it is shown here attached to a Redstone launch vehicle like the one that boosted astronauts Alan Shepard and Gus Grissom on sub-orbital flights in 1961.
