Should you go to Mars? ft Bill Nye

If we could put nuclear rocket engines on icy body asteroids like Vesta and then years later crash it into Mars they could nudge it towards the sun, add water,  add atmosphere, add gravity, anything would help but really to teraform mars I thing you would need Ceres  and all the smaller icy asteroids in the belt.  It's too much work but if you could do it in 100 years then maybe you could teraform mars.   Before you go to mars send your supplies ahead of you and then bring your own again and have super concentrated foods in the event of the loss of food.  There are oxygen generators, they use them on nuclear submarines, they burn a very high oxygen concentrate chemical which puts off more oxygen than it uses to burn.  It's called a candle and there is a recent video on it, I can find it if anyone really wants to watch it.  Bill is a nice guy but doesn't know everything accurately .
