That's OK. There are hundreds of millions of vegetarians on this planet, more than enough to populate Mars, assuming they qualify. Dugald Walker

February 18, 20224 yr I just finished reading this Wiki article on Mars colonization. Quite interesting. As most of you know I am not a fan of either colonizing Mars or of Elon Musk. But this should be a must read for those supporting Mars colonies. It is neither pro or con but a good treatise on what's involved. https://en.wikipedia.org/wiki/Colonization_of_Mars Noel The tires are worn. The shocks are shot. The steering is wobbly.

February 19, 20224 yr Musk himself answered one of my questions here. Musk told Time – the “goal overall has been to make life multi-planetary and enable humanity to become a spacefaring civilisation”, starting by building a “self-sustaining city on Mars and bring[ing] the animals and creature of Earth there”. I hope he leaves mosquitos out of the Ark. I hate mosquitos. Noel The tires are worn. The shocks are shot. The steering is wobbly. But the engine still runs fine.

February 19, 20224 yr I don't know Dugald. People here seem to think the Mars colony will be another Eden. Just hope he doesn't send an apple tree up there. I think a Mars Colony replica in the desert of Arizona with all of the deprivations would be appropriate to see how long term living off earth would work out. Start from scratch and over a period of time add more and more people. If that works out then a test colony on the Moon as a base for eventual launching to Mars. Noel The tires are worn.

February 19, 20224 yr Author 12 hours ago, DD_Arthur said: Fast turnaround on a return trip to Mars seems rather meaningless. It isn't fast turnaround for the return trip. The video depicts a full scale Mars Dome with a long term presence. Fast turnaround is in terms of launching materials there to build and populate. Many ships, a lot of cargo. Rather than your... "spend a decade building a huge factory in orbit which requires a multitude of rocket launces taking a huge amount of materials into orbit, yet more launches taking workers who need to be able to withstand micro gravity for probably years building your mega sized Mars ship, they can't of course so you'd need even more rocket launches for worker replacement every few months, yet more launches taking food and cargo. Then eventually, ten, fifteen years later your mega Mars ship is complete. But wait, simultaneously your plan involves doing the same thing, somehow, in Mars orbit. Then, finally, you can launch your mega Mars ship. By this time a couple of decades have past but we arent finished yet. Now it's time for more multiple, smaller ships to ferry everything down to the surface. A bit complex and time consuming. Let's stick to numerous rapidly built SpaceX Spaceships. Reusability and rapidity is just what we need for the several refueling sessions that will be required for each ship.

It will be challenging and definitely not a pleasure trip for the first few, and probably even couple hundred, people to go. We do have some ideas about how living in more extreme environments work between the research stations in Antarctica, space stations such as Mir and the ISS, and yes, even a dome in the middle of the desert, Biosphere 2. SpaceX will be using data from all of this in designing their colony. https://en.wikipedia.org/wiki/Biosphere_2 Edited February 19, 20224 yr by goates Missed a word
