Kinda funny that people like Musk whine about the CO2 levels in our atmosphere passing an arbitrary 0.04%, but they want a million of us to visit a freezing cold planet with a lethal 96% CO2 atmosphere.
Oh well. It sells his cars, batteries & solar panels I guess.
As I say I think he has great Marketing but apparently: Elon Musk is too scared to go to Mars himself http://www.technobuffalo.com/2016/10/02/elon-musk-...Oh well. It sells his cars, batteries & solar panels I guess.
At least Richard Branson was reported to say he going to fly on Virgin Galactic with his family : http://www.mirror.co.uk/news/world-news/richard-br...

AIUI Musk intends to travel to Mars, but only after the wrinkles have been worked out; he said he viewed the first trip as having a high risk of death, he didn't rule it out in perpetuity.
That OK then............. so the 2nd, 3rd or 4th won't be risky, what if the first 100 all die on the way to Mars or shortly after because that is the level of risk he is proposing. Is that ethically and morally OK Toaster said:

They just need to have stuff pre-positioned and choose adventurous, capable people. I don't think they'll have a problem finding enough volunteers that can do it.

Fingers crossed all the handwringers wont go as they'll be tooo busy habdwringing and only the 'right sort' will end up going there.
Interesting article on the testing of the Raptor on nsf
https://www.nasaspaceflight.com/2016/10/its-propul...
Its a 1MN 'scale model' of the 3MN engine destined for the BFR. Quite an advanced design.

They sure burn clean, those LOX / Methane rockets.

This is NASA's Morpheus Lander test vehicle, which also runs off LOX / Methane.

Reusable rockets have been in development for years: Technologies have changed making it cheaper and perhaps more reliable so whilst the Space X is getting glory the technology has been developed before https://youtu.be/JzXcTFfV3Ls The program ran from 1991 to 1996
15 crew to prepare and launch and could be re-launched within 24 hours sounds familiar doesn't it. So maybe Space X is copying refining and productising that has gone before after all it is funded by NASA and I would be highly surprised if knowledge wants shared as well.

Erm but there were human communities already living there, and contrary to popular beleife America was colonised before Columbus you probably need to brush up on Americas history a little.They just need to have stuff pre-positioned and choose adventurous, capable people.

Mars is nothing like America, and those who settle may find it impossible to return to Earth,
So lets think for a moment around the Science that is required and the meaning of what lays in front of the individuals who go, you will always be inside a building a small one at that, never going outside and feeling the wind, sun, rain, snow. a walk in the woods taking a boat out.......just a red rocky planet with no air 1/3 gravity.
In time there may be a Vegas type environment, possibly a Dome to live under in the mean time as these guys say its going to take some amazing science and meticulous planning https://www.futurelearn.com/courses/survive-mars?u...
So as this is a Science thread rather than people putting up plastic airfix models (and yes I built those as well) it would be really nice to see some intelligent dialogue about the challenges and how this will happen.

Are you advocating not to bother? Or are you just being a nay sayer?
Nope I am saying there is a distinct lack of realism, wooohooo we are off to colonise Mars. But there is a lot not explained by the current plan to colonise Mars and a distinct lack of detail. With my cynical head on its like the buildings in a wild west film.
Lets build a space ship to send 100's to Mars:
Where is the Oxygen coming from
How are the people being protected from radiation
What is the long term effects on the human body of 1/3 gravity
What about supplies until the garden of eden can be grown
does the radiation affect the plant seeds? and the food that is eaten
What are the energy sources to be used?
How much water is needed
What is the long term Psychological impact on human health
Who is going to pay for all of this? the list goes on and on and there needs to be practical answers and discussions
You may have guessed, this isn't Star Trek, there is no warp speed or teleporting
