I thought i say the military back in jfk day built a ship called orion that uses the exact same propulsion of detonating bombs behind the ship it worked snd they were able to get to saturn in about 7 years
Project Orion was an engineering study, it was never built. Travel time to Saturn would be far less than 7 years. You can read about the historical Project Orion in my journal here Orion: Nuclear Pulse Propulsion just follow the link and scroll down to section 2, under the heading 2. Historical Background: Orion Nuclear Pulse Propulsion. There are numerous links included in the journal if you want to know more.
