Title:     Project Orion: 1957-1965

Abstract: In November of 1957, a small group of scientists, working at the General Atomic division of the General Dynamics Corporation, with
support from the Advanced Research Projects Agency, The US Air Force, and the Atomic Energy Commission, launched a serious attempt to build a 4,000-ton interplanetary spaceship propelled by nuclear bombs. With a specific impulse of 4000 seconds, voyages from Earth's surface to the satellites of the outer planets, with a return to 300-mile earth orbit, could be accomplished in a single stage. The initial plans called for missions to Mars by 1965 and Saturn by 1970, in ships carrying fifty people and payloads of one thousand tons. After seven years of work, the project’s technical challenges appeared surmountable, but political obstacles brought the effort to a halt. Thanks to newly-declassified documents and interviews with surviving participants, we now have firsthand views of this project that were unavailable at the time.

Stimulants available 15 minutes before the talk.
