Add a velodrome to the Mars colony site for great exercise! You could actually make your own g's, I calculated a 4.5 meter radius cylinder at 6.7 meters per second would make one g. Or how about having a circular path on the BFR so you could make your own g's while on the way to Mars. Get your exercise and g conditioning at the same time!

I am thinking bicycles to get the necessary speed.
- I don't think you can count on that being an acronym people would know, though!
I dont see domes happening because of radiation. Domes are a staple of how a sci-fi colony looks like, but a more realistic design will be as much underground as possible. Especially if we are talking about an actual colony where people live and procreate long-term, and not just for six months.

Especially if we are talking about an actual colony where people live and procreate long-term, and not just for six months.If you think about it, what is one of the most successful organisms in nature? Ants come to mind. Deep underground habitats provide the perfect protection from radiation, climate, as well as space debris. On earth, this has been for ants. The deeper you go, the better off you'll be. Also, if it were up to me, I would put all food farms and equipment deep underground - again, protection is paramount. I do understand the need for a psychological outdoor-like space - perhaps for recreation. Although, besides solar panels for power production, nothing of importance should be exposed at the surface until a mature colony has developed with enough materials and resources to quickly replace anything lost to natural disasters.
The structural strength of a dome acts inwards, not outwards.

Unfortunately, being half-spheres, you have in effect cut through all of the force-carrying great-circles, except the rim. So all of the distribution of force ends up pulling on the rim.
Here we go again !
Ludus,You talk of green spaces and farming. Where do you envisage the light coming from? (O'Neill colonies have giant windows and mirrors, and orbit facing permanently at the sun.)
I don't think it's an accident that Elon started the Boring Company, tunnels will be very important in the first steps of living on Mars, before we build domes and terraform.
