RRM-3 was extracted from Dragon and is now on Dextre.

I measured the distance in the image from:
the scale here is fine

HiRISE 1.5x and 7° rotated, distances are incorrect

Locations of InSight, its Heat Shield and its Parachute, distances are correct

Hi guys!

Now my work proceded with the painting of the model. I started by painting the while parts but using white primer and not the classic paint.

The choice  was dictated by waiting to reproduce a thermal coating effect as it was, in realy, on the ATV.

This photos show the work painting.
Very beautifull; thanks for the big work to realized this book!
Manoeuvres continue.

My theory is that this tower is the Control Center / Observation Tower, like they have a airports. I believe it will be styled to look like the Starship with the windows facing the launch pad and fins too. If I am right the height should be about 40 meters on cylindrical part before tapering the nose. If each ring is ~4 meters and the base 5 meters then about 9 rings high. So we will see if they add 4 more rings.
General view of the colony.

Rather than greenhouses, long compressed Earth block structures with pressure resistant hoops and artificial lighting (600 W/m2 peak, 300 W/m2 average) serve for food production.  They are not buried as plants are more resistant to radiation damage.  Plant nurseries might be in covered areas though.

A solar farm slightly larger than 1km x 1km provides power.  Fuel production and some food production are stopped during storms, leaving plenty of energy to run the habitat.

The colony has already tunneled entirely through the crater rim and the small plateau, and emerged on the other side.
Then there will be some algae tanks for animal feed and oil, plus some chickens and rabbits, and some sort of rice.  Herb gardens, probably in the habitats themselves, to add variety cheaply.  Tilapia fish.  the usual, I guess.

I'd add insects. You can raise larva on human/animal waste. Then feed the larva to the fish and chickens. (Chickens apparently adore eating insect larva; not only is it a protein rich diet, but it seems psychologically positive for the animals compared to normal feed, reducing their stress response.) The three-species process (humans-insects-chickens-humans) should virtually eliminate re-infection of humans from their own waste, assuming there are infectious agents we can't exclude by quarantine. The insect waste itself ("frass") should be directly suitable for plant fertilisation.

(And insects and worms raised on plant waste could be eaten directly by humans, if the settlers are so inclined. And again the frass and castings should be directly suitable for plant fertilisation.)

I'm rather worried about freezing greenhouses during the night. There will be lots of radiation losses at night.

Not just radiation. As I've said, conduction to air dominates at modest wind-speed. (And therefore heat loss will be complex to model.)
Conduction can be tricky, perhaps not with a single wall greenhouse, but with any double walled or insulated vessel you can get surface temperature that are close to the environment temperatures and that make convection very low.
