I never think the word "believe" sits well when it comes to matters of engineering and science.

It’s a word used by scientists when something is beloved to work in a certain way but the evidence still needs to be compleated completed. It is often used by those with good authority on a subject, it’s often based more on overal knowledge of a subject and a bit more than guess work.

EFA

But you missed ‘beloved’

I thought that was legit. You know like an 1988 loving restored fiesta turbo...

I believe that’s quite a nippy little motor.

LOL, I wouldn't know, I lost interest when I saw the prices!!!

lol that’s quite funny I should read befor I post bloody auto correct.

It's 10 years since SpaceX's first successful launch. Only 8 years since the first Falcon 9 launch too.

This is always an interesting thread, a rare one that usually avoids petty arguments and pedantic spelling correction, please don’t start spoiling it now

You ok hun? Don't recognise a joke?

Back on topic. Are the relatively large windows on these machines technically achievable? And the transparent dome on the planet's surface?

[Kccv23highliftcam]

my bad...

The BFR windows do look vulnerable, but I guess they know what they're doing. It'll be interesting to see if they have to change them as their development continues. Perhaps a Concorde-style outer windshield or protective shutters.

Habitation domes are a bit of a cliche, but they do look good. If they can work out a way to turn Mars dirt into a concrete they could make domes, like in this competition that NASA ran recently:

I think they'll most likely go with cylinders that can be partially buried and covered with a light protective covering of dirt. At least at first. Easier to produce, store and transport too I would imagine.

Monolithic domes have been used on Earth for some time and this is how they make them:

I think at least partially buried would make sense. Insulation and radiation protection would be critical, anything transparent on the surface would be difficult. I admire the chutzpah with illustrations of the settlement but they do look very 1950's sci-fi, I think the reality will be very different if it ever happens.
The psychology and mental health of the crews will be very important and perhaps more difficult than the engineering challenges.
Being on the ISS for months or even a moon mission is different; at least 'home' is visible, contactable most of the time in almost real time and on the ISS at least, an escape and rescue is potentially possible. A Mars mission is a different ball game.

Tunnels under the surface rather than construction on the surface, hence The Boring Company.

It would take some heavy lifting to get a boring machine to Mars.

Nothing an EBFR couldn't cope with.

I think physics will get in the way.

[Eric Mc]

Landing it on Mars is the hard part.

[Polite M135 driver]

It’s a tunnel boring machine, doesn’t matter if it makes a hole when you land it.

[Zad]

Making a hole when you land it, and also being able to use the thing again is a different matter.
