![]() The Earth is attacked from space; all military forces and spaceports are destroyed. How can humanity get back into space with what they have, and destroy the invaders?
There was a real Project Orion; it originated at General Atomics in San Diego. Physicist Theodore Taylor and others examined the feasibility of a nuclear-pulse rocket powered by nuclear fission. The original idea was put forward by Stanislaw Ulam and Cornelius Everett in 1955. Bombs set off on one side of a pusher plate with some solid propellant material would push on the plate, moving the craft forward.
Aldo Spadoni of Aerospace Imagnineering has created detailed technical drawings of Michael, working with Larry Niven.
![]() (Michael [Drawing by Aldo Spadoni]) Read more about the real Orion Project. Here's another example of the same idea, the Atomic Pulse Rocket. I believe the cool picture is part of an ad campaign for American Bosch Arma (a defense contractor) in 1958-59.
![]() (Atomic Pulse Rocket [American Bosch Arma]) Weighing in at about 75,000 tons, and roughly the size of the Empire State Building, this behemoth would leave the atmosphere under the influence of about a thousand atomic blasts. Each atom bomb is fired from a low-velocity gun into a heavy steel rocket engine at the rate of one per second. Steam and vaporized steel from the combustion chamber maintain thrust. Living quarters are housed in the wheel-like cabin, which can of course be spun for artificial gravity. Comment/Join this discussion ( 3 ) | RSS/XML | Blog This | Additional
