Will nations combine to put Humans on Mars or will we end up with separate missions?
Did any scientists or other figures in Soviet society advocate the colonization of Mars?
After Rogozins trampoline remark it took Musk 6 in a half years which is like an enternity to send a crew to the ISS and the seats sold for that are way higher than the advertised falcon 9 costs. I dont even think he has docked anything in the ISS despite all the talk with nauka until it made a successfully docking. So getting 2 100 ton spacecrafts for one to fuel the other I will give a very optimistic 10 year time frameAlso the idea that they will simply "manufacture" in-situ the hundreds of tons of rocket fuel that they will require for the return jouney. The last time I looked, none of those nations that have significant perma-frost areas (ie Russia and Canada) have ever developed a pilot plant to extract frozen ground water and convert it into LOX for oxidiser, or to extract minute traces of methane in the atmisphere and liquify it for fuel. Mars doesn't have any significant methane sources, despite the hyperventilation over trace quantities in the atmosphere.My challenge to these Space-X fans is to build a small nuke-powered pilot plant in the Canadian or Alaskan wilderness and demonstrate the feasibility of in-situ fuel manufacture using components that could reasonably be carried in a stripped down "Starship" (Gods, how I hate even writing that word..) and which can be assembled, commissioned and operated by a skeleton crew (or better yet, by robots). So show that that sabatier process works on earth, how long it will take before getting the starship to leave Mar's atmosphere. I am looking at a longer timeframe than what I gave on the orbital refueling process.Rogozin estimated a 8-10 year time frame to get a man to mars last year on August but only if they are given adequate funding which makes it sound like they are not doing the Space X approach but with something nuclear sounding more simple than orbital refueling or mining for fuel. So with Nordstream 2 almost built and getting arctic oil projects to have trade routes with the Indians and Chinese later it might happen. If they managed to land a 20-30 ton nuclear tug on Jupiter's moon in 2030 while Space X is still on the orbital refueling phase than were screwed. Even if Space X or the Chinese did get to Mars before the Russians, *knock on wood* I dont see the timeframes feasible for space expoloration or colonization beyond Mars while still using chemical rockets without switching to MPD thrusters like the Zeus nuclear spacecraft for project nuklon.

Just remember Space X has an amazing track record of projects they promised. <youtube nonsense removed from original post>The current perserverance rover is having problems collecting rocks yet I am expected to believe that Space X will do better in collecting and using Martian soil alot better than a company that has sent rovers there for years for fuel. I believe that Space X will eventually get to Mars but I am not one of "those believers" that think he will get their in 2026. Hopefully the Sabatier process gets thoroughly explained by them later and how much liquid methane fuel they can draw a day and not ends up like the tesla self driving cars.Is NASA's manned mars 2033 with nuclear reactor/ MPD thrusters plan still in effect? https://www.researchgate.net/publication/237827299_Use_of_High-Power_Brayton_Nuclear_Electric_Propulsion_NEP_for_a_2033_Mars_Round-Trip_Mission
