Project Orion: Using Atomic Bombs to Propel Objects into Space
TLDR Project Orion was a project funded by DARPA that aimed to develop a spacecraft propelled by nuclear explosions. Although the concept of nuclear pulse propulsion still has potential applications in space, the project never gained widespread support due to issues with stability and concerns about radiation and nuclear fallout.
Timestamped Summary
00:00
Scientists after World War II wondered if atomic bombs could be used to blast ships into space, leading to the development of Project Orion.
02:35
Project Orion was a crazy idea that involved using atomic bombs to propel objects into space, and some very smart people determined that it could actually work.
04:36
Project Orion was a project funded by DARPA that aimed to develop a spacecraft propelled by nuclear explosions, and the team had to figure out how to design a vehicle that could withstand the force of the explosions.
06:32
The vehicle for Project Orion would have to be large and well built, made from heavy materials like iron and steel, with a broad pusher plate to withstand the force of the nuclear explosions, and a shock absorber system to even out the jolts.
08:28
The Project Orion team believed they could complete a round-trip mission to Mars in just four months using a system that generated more thrust than chemical rockets, but their test using conventional explosives showed issues with stability and the project never gained widespread support.
10:37
The problem of radiation and nuclear fallout, as well as the passage of the Test Ban Treaty, led to the decline of interest in Project Orion, but the concept of nuclear pulse propulsion still has potential applications in space, such as deflecting asteroids.
12:42
Nuclear pulse propulsion, both in the form of fusion-based systems and non-pulse nuclear rockets, still have potential applications in space exploration and NASA is currently working on a non-pulse nuclear rocket system.
