	Amazon.com: Books: Project Orion: The True Story of the Atomic Spaceship
		In his latest, Dyson (Darwin Among the Machines) charts the history of the failed Project Orion, which called for a massive rocket to be built atop a nuclear-powered piston.
		A great strength of Dyson's project is the interviews he conducted with surviving Orion team members among them his father, Freeman Dyson affording readers an intimate view of the story's central characters (and its government contractors) who helped shape Orion.
		The project's physicists and engineers, buoyed by the thrilling idea of traveling through space on "pulse technology," conducted a number of explosive experiments to ascertain the abilities of such a system (which reveals how little was actually known about the bombs being produced by the world's superpowers).

	Project Orion - Wikipedia, the free encyclopedia
		Project Orion was the first serious engineering design study for a spacecraft powered by nuclear pulse propulsion, an idea first proposed by Stanislaw Ulam in 1947 as a means of propelling solid discs into space.
		From 1957 through 1964 this information was used to design a spacecraft propulsion system called "Orion" in which nuclear explosives would be thrown through a pusher-plate mounted on the bottom of a spacecraft and exploded underneath.
		Some Orion nuclear pulse rockets using megaton range nuclear fusion type pulse units are capable of accelerating a spacecraft with a mass of millions of metric tons to velocities as high as 10% of the speed of light in space flight.

	Project Orion: Its Life, Death, and Possible Rebirth
		Project Orion was a space vehicle propulsion system that depended on exploding atomic bombs roughly two hundred feet behind the vehicle (1).
		The core of the vehicle was a 200,000-pound "propulsion module" with a pusher-plate diameter of 33 feet, limited by the diameter of the Saturn.
		His 1968 paper (53) gives more physical details of nuclear pulse drives, and even suggests extremely large starships powered by fusion explosions.

	Building Tomorrow's Space Battleships with Today's Tech
		Legendary physicist Freeman Dyson worked on a nuclear pulse propulsion concept with a project called Orion in the late '50s and early '60s, creating several working test vehicles propelled by explosives before the 1963 Nuclear Test Ban Treaty ended his research..
		Meanwhile, a nuclear pulse engine is probably the most immediately available of many possibilities, according to John Cole, the Marshall Center's manager of space transportation research.
		Using a new propulsion system known as M2P2, it would be 10 times faster than the space shuttle and could zip by Voyager I, launched in 1977 and currently 6.8 billion miles away, at the very edge of the solar system.

	The UnMuseum - The Orion Project
		Perhaps the scientists, so long involved in the building of nuclear weapons for the purpose of mass destruction, had finally found a positive, uplifting goal for their skills and they went at it wholeheartedly, not taking some of the difficulties of spaceflight into consideration.
		A rocket powered with a nuclear reaction, however, could produce a huge amount of energy from a very small amount of fuel in the same way a nuclear bomb produces a huge explosion compared to a conventional bomb of the same weight.
		The concept of using nuclear fission to drive a spaceship is far from dead, however.

	Gateway: Problems With The Orion Spacecraft
		Orion was a spacecraft propulsion concept first thought of in the US of the 1950s, which would drive a spaceship by having it pushed by the shock wave of exploding nuclear bombs.
		Orion's only chance for funding at that point was NASA (apart from the entirely nonexistant nature of a civilian market for space launch capability at that time, the project was classified).
		For a project with the high absolute cost of an Orion (which really is a "put all or most of your eggs in one basket" approach to launch capacity), and with all the detrimental side-effects and risks of an Orion, its backers would not be willing to risk cutting too many corners in the construction.

	Project Prometheus
		The technology was studied in the 1950s and 1960s in initiatives such as NERVA and Project Orion, but was subsequently dropped, partly for political (1963 nuclear test-ban treaty) and partly for financial reasons.
		The project is managed by the Jet Propulsion Laboratory (JPL).
		One of the first practical applications of the Prometheus Project is likely to be the Jupiter Icy Moons Orbiter (JIMO) – a mission to study Callisto, Ganymede, and Europa.
