Project Orion

Project Orion.

A serious attempt to design, circa 1963-4, a similar spacecraft for NASA interplanetary missions. The image below shows a miniature flying prototype of the Orion vehicle - built by General Atomic, a company founded by Teller's protege Frederick de Hoffmann - which made a successful flight to an altitude of about 100 meters in November 1959, during which it ejected several small conventional explosive charges in rapid succession.

By the early 1960s, General Atomic had advanced the Orion concept to studies of a vehicle capable of sending a crewed expedition to Mars. This vehicle was sized to the diameter of the Saturn V rocket and was to be launched in several sections and assembled in Earth orbit. A Mars mission of several months duration with a crew of eight was planned. Landing on Mars was to be accomplished by an advanced lifting-body vehicle

Nuclear "pulse unit" of low kiloton yield. Hundreds of these bombs would be used to accelerate Orion to interplanetary speeds

Hmm...we're powered by a series of blasts generated by deploying nuclear bombs and exploding them behind us....SIGN ME UP!!! LOL!!! Yeah, right!

I remember seeing this design a while back. Would likely be tough getting people to sign for this mission, hehe....

Don't forget to fasten your seatbelt.

Thanks.

Interesting link.

I've read in a science magazine tha NASA worked on a long range AMERICIUM 157 (or around this atomic mass) for a spaceshio to travel to mars.

do go through the links -e.g. www.islandone.org...
there is plenty there.

QUOTE:

Von Braun became an enthusiastic Orion supporter, but he was able to make little headway among higher-level administration officials. In addition to the general injunction against nuclear power, very practical objections were raised: what if a Saturn bearing a propulsion module with hundreds of bombs aboard should explode? Was it possible to guarantee that not a single bomb would explode or even rupture? NASA's understandable fear of a public-relations disaster contributed to its reluctance to provide money (47); however, its Office of Manned Spaceflight was sufficiently interested to fund another study (48).

A hammer blow was delivered in August 1963 with the signing of the nuclear test-ban treaty by the U.S., U.K., and U.S.S.R. Orion was now illegal under international law. Yet the project did not die immediately. It was still possible that an exemption could be granted for programs that were demonstrably peaceful. Surely the treaty reduced Orion's political capital even further, though. Yet another problem was that, because Orion was a classified project, very few people in the engineering and scientific communities were aware of its existence. In an attempt to rectify this, Nance (now managing the project) lobbied the Air Force to declassify at least the broad outline of the work that had been done. Eventually it agreed, and Nance published a brief description of the "first generation" vehicle in October 1964
