NASA artist rendering, from 1999, of the Project Orion pulsed nuclear fission spacecraft. Project Orion was a study conducted in the 1950s and 1960s by the United States Air Force, DARPA, [1] and NASA into the viability of a nuclear pulse spaceship that would be directly propelled by a series of atomic explosions behind the craft.
Project Orion was the first serious attempt to design a nuclear pulse rocket. A design was formed at General Atomics during the late 1950s and early 1960s, with the idea of reacting small directional nuclear explosives utilizing a variant of the Teller–Ulam two-stage bomb design against a large steel pusher plate attached to the spacecraft ...
This is a timeline of known spaceflights, both crewed and uncrewed, sorted chronologically by launch date. Due to its large size, the timeline has been split into smaller articles, one for each year since 1951. There is a separate list for all flights that occurred before 1951.
WASHINGTON (Reuters) -The United States plans to test a spacecraft engine powered by nuclear fission by 2027 as part of a long-term NASA effort to demonstrate more efficient methods of propelling ...
The U.S. military is giving Lockheed Martin $33.7 million to make a nuclear-powered spacecraft. Here are the details. For the First Time Since '65, the U.S. Military Will Blast a Nuclear Reactor ...
Orion spacecraft as of December 2019. The Orion spacecraft was designed for the Constellation program as a crew compartment for use in low Earth orbit. Lockheed Martin was selected as the prime contractor for the Orion project on August 31, 2006, [18] and Boeing was selected to build its primary heat shield on September 15, 2006. [19]
Nuclear power sources could also be used to provide the spacecraft with electrical power for operations and scientific instrumentation. [12] Examples: NERVA (Nuclear Energy for Rocket Vehicle Applications), a US nuclear thermal rocket program; Project Rover, an American project to develop a nuclear thermal rocket. The program ran at the Los ...
