Vmedvil2 Posted July 7, 2021 Report Share Posted July 7, 2021 It seems that nuclear powered spacecraft are almost ready for usage on spacecraft and are being deemed the next frontier in space travel, read more at https://www.geekwire.com/2021/space-nuclear-power-nearing-critical-mass-final-frontiers-next-frontier/ Quote Link to comment Share on other sites More sharing options...
darkmatter42 Posted August 19, 2021 Report Share Posted August 19, 2021 I am NOT a rocket scientist, or any other scientist (yet), but wouldn't an ion drive be more efficient and less dangerous? Quote Link to comment Share on other sites More sharing options...

Even if you had a ion drive you would still need a power source for the ion drive, nuclear is just the power source of the spacecraft.

darkmatter42 Posted August 23, 2021 Report Share Posted August 23, 2021 That makes sense. But Nuclear propelled spacecraft are different from Ion-propelled spacecraft, even if they can use the same power source. Quote Link to comment Share on other sites More sharing options...
darkmatter42 Posted August 23, 2021 Report Share Posted August 23, 2021 I'm thinking of the best to be used on like a generation ship meant to travel to the stars. Quote Link to comment Share on other sites More sharing options...
darkmatter42 Posted August 23, 2021 Report Share Posted August 23, 2021 Maybe both? Each can be used for a certain purpose. Nuclear for the most part and Ion for use near a planet. Quote Link to comment Share on other sites More sharing options...
darkmatter42 Posted August 23, 2021 Report Share Posted August 23, 2021 Ooooooh.... difficult but plausible! I never really got into how those work. Can you explain? Quote Link to comment Share on other sites More sharing options...
darkmatter42 Posted August 23, 2021 Report Share Posted August 23, 2021 I'm 14, so I am definitely not as knowledgeable as everyone else on this site. Quote Link to comment Share on other sites More sharing options...
darkmatter42 Posted August 23, 2021 Report Share Posted August 23, 2021 I looked it up. Antimatter propulsion, according to Ryan Weed, could go up to 72 million mph Quote Link to comment Share on other sites More sharing options...

Antimatter propulsion, according to Ryan Weed, could go up to 72 million mph The only problem with Antimatter powered spacecraft is mass production of antimatter is basically impossible at this time. Fusion/Fission, nuclear reactions are still our best bet as a energy source for the time being. Humans are still rather limited in the way of technology and what we can actually put into practice, antimatter is just not viable at the current time due to production limitations, Fermilab and CERN have only created nanograms of antimatter. The best emitter of anti-particles we have is a synthetic isotope called sodium 22 which regularly released positrons in beta positive decay which is generally used in the creation of positrons for anti-hydrogen production, but the anti-protons are created from energy(https://home.cern/news/press-release/cern/first-atoms-antimatter-produced-cern).
