Hey Cody! Love your solution ! But have you heard of the theory of placing a rather small electromagnet at Lagrange point L2 right between the sun and Mars and create a electromagnetic field as to repel solar winds to make an atmosphere on Mars. I've heard the energy that would be needed for such electromagnet would be minuscule (not even a hundredth of what USA makes annually iirc). Could you have a look about the calculation and do a little video about it please? Keep it up 👍

Geomagnetic fields are super overrated. You can give Mars 10x Earth's magnetic strength and in 1 billion years there'll be marginally a difference. Mars won't grow itself an Earth-like atmosphere overnight. If you have the ability to raise Mars air pressure +100x to match Earth's, then that same mechanism can be used to top-off the absolutely miniscule amounts the solar wind strips away (yeah, it is *miniscule* on human timescales).

I don't think it changes. There's a very simple experiment used to calculate the coefficient of friction of materials, where you just put a block over a flat plate, and incline the plate until the block moves. That angle lets you calculate the coefficient of friction, and it turns out you don't need to know what the gravity is, because it affects the force pushing the block down the same as the normal force, which causes the friction that keeps it in place. Every force is scaled with gravity proportionally, and you just need to know which one is bigger, so gravity doesn't matter. I think sand behaves similarly

The angle of repose uses a formula from Statics, based on Newton's first law, so it isn't affected by gravity - mostly just friction and material composition. In this case, it would matter more about how smooth/round the pieces of rock are. Check out the Mark Rober's video about how adding air to cause sand to behave as a liquid because it reduces the friction. Its a really interesting experiment. Therefore, blasting a conical shaped hole would need an additional angle for safety factor to ensure regular sandstorms or earthquakes (marsquakes? lol) don't cause rockslides when movement does occur. But that's about it. Static materials are actually very predictable.

No, that is a different concept. What I'm sceptical about though, is whether the atmosphere would actually be thick enough. Also, martian dust still remains a big problem that needs to be solved. Additional fake 'gravity' could in theory be made by making all inhabitants wear suits with ferrous metals in them, and have permanent magnets (perhaps made from martian ores) in the flooring. A later game option could be genetic engineering of humans, if, a private company decided to work on that. That's probably gonna take a long time, but once the technology is there, designer ecosystems could even be a thing. I think that especially, random gene editing research will give us the most data on the relation between certain genes.

The other thing i could imagine being a problem is that part of the atmosphere will probably be ejected by this as well , i am no physicist so i am not sure if it would be a significant number or if it would even contribute to the already low atmospheric pressure by essentially evaporating a part of the ground material.

I think i see where you come from with this assumption but the impact isn't actually making a dent like hitting metal with a hammer, its faster and has much more energy so when it hits, the ground will sure be compressed at the impact site but the mass will not be pushed through the planet and make a dent on the other side, the liquid planet core alone would prevent that and act like a cushion. Instead the compressed mass will try to find a way to decompress, going straight up is no option since there is a rock on top that had ludicrous speed and therefore will not just allow mass to fly upwards , down works a bit but the compressed matter will want to go somewhere , so it will spill out upward on the side acting like water when you throw in a stone. There is so much energy in play there that the ground really just acts like a liquid. Most of the energy will be distributed there, the rest will move as earthquakes through the ground but it won't be enough to have any direct effect on the other side of the planet.

This could be a good setting for a sci fi / fantasy story, set entirely within the crater. There could be a wealth gradient, where as you get further from the center of the crater they lose more and more resources, eventually losing oxygen as the cities climb up the sides of the crater. Perhaps a large tower is built atop the central meteor, or built from it that houses the government and the most wealthy. The main character could be someone coming from the edge of the basin, traveling inwards in hopes of success and meeting people along the way, or someone who is exiled from the center to the outskirts, or even outside the crater itself, perhaps he finds other craters that were hidden from those within the crater, like how the other cities were hidden in divergent.

That's an interesting idea for sure. Also, depending on the composition of the asteroids used, you may be able to offset the reduction in atmosphere outside the crater as the volatiles (like H2O and CO2) trapped in the asteroids are released upon impact. Then again, that could potentially be offset by the sheer volume of material that will be flung into space at escape velocity.

Mathematically it isn't possible to contain all of the atmosphere in any size open hole. There is an asymptotic approach to 100%, so a better question would be how big to contain 90% or 98% of the atmosphere. But even then you need to define the construction of the hole, where on the planet is the excavated dirt deposited, what is the ratio of width to height, etc? (It all effects the local gravity and thus the pressure and density gradients.)

I asked you to cover this idea some years ago, Cody, and so glad you did... Now we just have to find 3 suitable asteroids and impart enough momentum and next level orbital mechanics to get them to impact at the right location and angle... I see a problem with that - the first impact will blow out a lot of atmosphere, and then the 2nd one would blow out the collected atmosphere as well. The amount of air around the rest of the planet would decrease dramatically too as it flows into the hole and compresses. Work out the volume of a cone with 100km base and 25km apex at 0.5 atm, and compare with the volume of the atmosphere at 0.01 atm - I expect it would be a significant fraction! We'd also have to wait perhaps decades to centuries for the crater to cool down enough to be visitable. Using electric remote mining vehicles with pretty much the same technology that we use to make deep open cast mines now may take a while, but at least they would be achievable after enough time. Perhaps one way that would take less than a lifetime would be to drill several parallel boreholes then knock them through at the bottom to make a large cavities. Sunlight could be concentrated and piped down via fiber optics, in addition to PV electric... Then habitable spaces could be built using membranes containing oxygen instead of heavy pressure vessels - perhaps one day, but it'll be a very long time before it could resemble anything here on Earth unfortunately.

A question no one asked, but everyone wanted the answers to. Mans a mad genius.

Love to see scientists like you who understand the gravitational nature of atmospheric pressure. Our own atmosphere is not nothing, though since its invisible gas many people can't understand that. Our atmosphere is made of wall to wall atoms and molecules. Even though they are invisible they still have gravitational weight and are held in place in the atmosphere by the Earth's gravity. And they are layered by atomic weight, with the heaviest on bottom and the lightest on top. Of course gasses toward the outer part of the atmosphere suffer competition between the Earth's gravity and extraneous bodies of mass like the Sun or Jupiter. As a result many, many metric tons of hydrogen, our lightest element, or least attracted to gravity, float off each year headed toward those other sources of gravity. Your theory to bombard Mars with asteroids may not be fully possible. I think you may be discounting the possible changes to Mars rotation and orbit trajectory as they apply to Mars gravitational changes as they may affect Earth or other planets and bodies of mass that flow through our solar system. I'm afraid these changes could be harmful to the gravitation ballet of all the bodies in our own solar system and possibly even beyond. I think the planet we are looking for will be one with an atmosphere capable of producing water in any of the three states it can exist.

The Earths gravity tries to keep the atmosphere in place while the moons gravity tries to to drag it. That causes wind. As the Earth rotates and the moon passes over there is a friction that causes turbulence in the air. So yes, there is some mixing of atoms in the atmosphere horizontally and vertically. But generally you will find a severely depleted amount of oxygen above 20,000 feet above sea level. At that level and higher you can only find lighter gasses. All atoms layer themselves like the oxygen atom does. The oxygen atom is not unique in that regard. Gasses rising does not occur instantly.

This heated up mass of Martian air will inevitably rise above the crater hight and will be eventually cooled by the freezing cold Martian winds.

In all seriousness digging "pit cities" on mars might actually be a really good idea to begin with. We'd need to mine for resources anyways, the lower gravity allows for somewhat easier extraction and mine tunnel systems could be larger. Digging a large quarry to get ores, rock and sand for building materials could then be converted into a city pit, even if the atmospheric pressure wouldn't be great enough for a livable atmosphere those pits would be more protected and could even be canopied to keep in a larger pressure. This canopy could be done in multiple layers: You have the outer atmosphere over the pit canopy, under it you have slightly increased atmospheric pressure which would push upwards against the canopy which would slightly counteract gravity pulling it down, then the city itself encased in smaller "domes" which have a "survivable atmosphere" (not pleasant to live in but you can survive in it) and finally the city main structures which are fully pressurized and have full air. Having it encased like this would also trap moisture so you could possibly use that to cultivate plants in a high CO2 atmosphere on the outside, you'd just have to find ones that can grow in lower pressure and lower light conditions. Also as you mentioned while Mars' core isn't as hot as Earth's it would still provide some geothermal heating. You could dig deep enough to the point where the heating could be used for geothermal power generation through heat exchange into the much colder atmosphere. This would also heat up your pit cities and, while I'm not an expert on that at all, possibly provide some heating for the atmosphere in general.

I would say better control of the speed of each asteroid, makes it simpler then getting a bunch to hit right after another. This way you could aim it and control its speed during the multi year journey from I assume the astroid belt. Then by accounting for the planets rotation and the asteroid's speed, it hits the target at as close to a 90 degree angle as possible making the atmosphere effects on the impact location pretty much nothing. Also by using asteroids and not comets that might start releasing gases that could offset the impact location.
