Half a century after humanity’s historic first step on the Moon, the Montana Historical Society is hosting a screening of the Smithsonian Channel’s The Day We Walked on the Moon. Astronauts (including Michael Collins, the third member of the Apollo 11 mission), members of Mission Control (including Flight Director Gene Kranz, Capsule Communicator Charles Duke, and Guidance Officer Steve Bales) and the children of Neil Armstrong and Buzz Aldrin reveal their personal stories behind the scenes of the iconic day. Pop culture notables like Queen guitarist and doctor of astrophysics Brian May and television personality and professor of physics Brian Cox describe where they were and what they felt during that “One Small Step.” It’s a story that ranges from the deeply personal to the grand and historic, an in-depth look at one of the most important twenty-four-hour periods in history.

The special screenings of The Day We Walked on the Moon will be preceded by a slide show, Montana 1969, developed by MHS historian Christine Brown, and moon rocks brought back to earth by Apollo 11 will be on display.
