For SpaceNut re doors in the proposed scientific airlock system for Mars...
https://newmars.com/forums/viewtopic.ph … 38#p236738
Are you asking a question about the flat doors?
I can't tell from the wording.
The round doors are (obviously) pressure doors.
The flat doors are dust doors that do not handle pressure, unless the very light Mars wind sends a few molecules at the outside.
It's time for our NewMars Airlock topic to start moving beyond examples provided by others.
We have the Image Server now to host images of designs.
The Image Server can host images of equations.
We can store non-image documents on Dropbox when that is necessary.
It should be possible for us to begin building a knowledge base that future Mars pioneers can access to answer questions about what size screw goes where in the outer sand door mounting flange.
If a person has never designed something before, they might not know that all designs start with arbitrary sizes and dimensions for things. Get started and someone will tell you soon enough if you are off base.
Calliban did not worry about someone telling him how large the dome should be. He liked 200 Meters and went with it.
No one objected, and lo and behold! It turns out the Superbowl is 208 meters in diameter. That is a quite feasible size.
We human have recent experience with it. Let's get started and plan to make adjustments as we go.

For SpaceNut re garage on Mars ...
Your recent posts have inspired this thought....
Let's consider creating a standard metal building for equipment maintenance out of the wind and free of sand.
Let's pick a building from the assortment of buildings on Earth. We have many vendors of build-it-yourself metal buildings.
We want the building to be large enough to handle whatever vehicles the various Nations will be sending to Mars in the early years.
Just pick one and see if it weighs less than 40 tons when shipped.
If it does, go to the next step. Can the building hold up to conditions on Mars? My guess is it will, because it is designed for Earth, and Earth is rough on buildings.
Does the building require a concrete foundation? What can we do instead?
GW Johnson has written about floor solutions for Mars. Can we use one of those?
Now to the crucial question: Can a robot or a team of robots assemble the building?
I don't think that has ever happened? Possibly not.
Can it happen? Of course it can. What does it take to make it happen? It should be obvious, but for our readers, I'll spell it out.... It takes a single human being who is obsessed with making it happen. Are there such human beings on Earth today? I think there must be, because there are so many difficult projects under way around the world in 2025.

Nice! Great Find! Nice Image!
Ok... we have two ways to go... Please do both.
I'd like to see the building you found developed further. That building is plenty large for a great number of vehicles, and you can make it as long as you need.
Please find out what the shipping weight of the entire structure might be. That would include all the panels and the frame and the fasteners.
There might be additional components but just include them. Please don't second guess the builders. They know more than you or I ever well so let's not waste time trying to redo their work. What I want to know is: will that system ship for under 40 tons, and will the panels fit inside a Starship?
*** The second path is to obtain the measurements of the Starship hull and determine what you can make by cutting it in half longitudinally.
If you do ** that ** you may have a structure strong enough to hold a meter or two of regolith, if you anchor the bottom correctly and if you pile regolith against the sides. Please do NOT try to solve ANY of the details yourself. Neither you nor I have ** any ** idea what needs to be done, but we have two fully qualified engineers in the group who do. Let's not waste any of our valuable time worrying about details.
I would like to see two proposals coming out of this topic:
1) Original Quonset hut building
2) Split Starship building
