Project Orion (nuclear Propulsion)
Project Orion was a study conducted in the 1950s and 1960s by the United States Air Force, DARPA, and NASA into the viability of a nuclear pulse spaceship that would be directly propelled by a series of atomic explosions behind the craft. Following preliminary ideas in the 1940s, and a classified paper co-authored by physicist Stanisław Ulam in 1955, ARPA agreed to sponsor and fund the program in July 1958. Early versions of the vehicle were designed for ground launch, but later versions were intended for use only in space. The design effort took place at General Atomics in San Diego, and supporters included Wernher von Braun, who issued a white paper advocating the idea. NASA also created a Mars mission profile based on the design, proposing a 125 day round trip carrying eight astronauts with a predicted development cost of $1.5 billion. Non-nuclear tests were conducted with models, with the most successful test occurring in late 1959, but the project was ultimately ab ...

Orion (laser)
The Orion Laser Facility (also known as the Orion Laser) is a high power laser facility based at the Atomic Weapons Establishment (AWE) on the former RAF Aldermaston site in the United Kingdom. Construction of Orion began in 2006 and its first shot was fired in 2010. The building houses a large neodymium glass laser system and a target chamber, and it is the biggest experimental facility of high-energy density physics in the UK. Orion delivers 10 "long-pulse" one-nanosecond duration beams and two petawatt (PW) "short-pulse" 0.5 picosecond duration beams. The facility also provides a comprehensive suite of optical, particle, and x-ray plasma diagnostics to understand the plasma conditions created through the laser interaction. 4.
