Nuclear Pulse rocket, Project Orion propulsion system

A nuclear pulse rocket, also known as Project Orion, is a theoretical propulsion concept that involves using controlled nuclear explosions to propel a spacecraft. In this design, a series of nuclear detonations would occur behind the spacecraft, and the force generated by the explosions would push the vehicle forward. While the concept offers potential for high thrust and efficiency, it presents numerous technical, environmental, and safety challenges that have prevented its practical implementation so far.
