The part I calculate as sceptical is when I try to calculate how thick insulation needs to be on the rocket, for the occupants to be in direct line to the sun for 3 - 5 days of 24hr direct sun without atmosphere.
Pardon my Physics guessing, but if standing on earth we have 15km of air atmosphere at weight of 1 gram per kilo mass of air at sealevel. Earths total atmosphere is upto 500km thick, But I will just calculate the denser 15km.
Using 1 sq centimeter , the density is 1 gram per meter long of 1 cm x 1 cm. So 1 gram per meter = 15,000 grams per 1 sq cm.
Thats 15kgs of density weight providing resistance from the sunlight onto a 1 sq cm of my skin.
I know that my skin couldnt stand being in direct sunlight for 3 days x 24hrs per day, even with 15kgs of air density surpressing the suns radiation onto my skin.
So for example, if the Rocket had the same resistance in its walls as does Earths atmosphere, it needs the equivalent density of 15kgs per sq centimeter of rocket wall, to protect the occupants even to just the level of being in the sun at sealevel.
I cant make sense of how a Rocket wall insulation, could protect the occupants from radiation exposure for 3 plus days at 24hrs per day in direct line to the sun with nothing but space between the rocket wall and the sun.
Im quite sure a rocket can take off, and people can sit inside a pressured tank at atmosphere pressure, But I cant calculate how its possible to protect the Occupants from radiation for that length of time.
The rocket walls would need to be so thick, the rocket wouldnt be able to take off.
