I wonder how hairy his chest is. Is it soft and furry like a cat, or is it tough and wiry like steel wool? What about his pubic hair, does he trim it or just let it grow? I don't think he would shave it. Would he ever give me one of his pubes if I asked? I could use it as a bookmark while I'm not reading The Case For Mars, and when I am reading it, I can play with it. Same with his armpit hair. I wonder what it smells like, and whether he ever forgets to put on deoderant.

what?

[Anonymous No.12673684]

>>12673673
Helium does not form compounds with any other element so unlike Hydrogen it's abundance outside of Gas giants is very low as it get's blasted by the solar wind from rocky bodies. That's why there isn't much Helium even on Earth, with it's dense atmosphere, as the Helium rises to the very top of the atmosphere and is swept away.

[Anonymous No.12673689]

>>12673673
And mining gas giants is difficult because you have to set up infrastructure to and from a planet several astronomical units from Earth with a much higher escape velocity. I mean Jupiter's escape velocity is over 5 times Earths. The Delta V requirement isn't as scathing as that might imply, but it's still immense.

[Anonymous No.12673731]

>>12673684
But helium is also a common form of radioactive delay (alpha particle), so it is constantly being produced.

[Anonymous No.12673742]

>>12673731
True, which is why Earth has more helium than any other rocky body iirc. However Helium 3 does not get produced by alpha decay so it's not very useful to us fusion wise. Unless we can somehow pull of the triple alpha process (not anytime soon).

It's present in parts per billion maximum concentration anon, right now it's not even possible to develop a system of extraction that has less than a 99% loss rate simply because helium is a slippery element and you need to process hundreds of millions of kilograms to get one kilogram of the gas.

This is incorrect, you would need a million tons of superconducting copper coils to make a big enough magnetic field. The field strength at the surface of the magnet doesn't really matter (otherwise a tiny neodymium magnet that could fit in your pocket would be sufficient), what matters is the field strength at a distance of several thousand km from the center of the magnet.
The way we would build a real-life electromagnetic planetary shield would be to have a rotating electromagnetic ring in space 2 or 3 thousand km across with a field strength of maybe a tesla right at the surface of the coil, because this would cast a wide enough bubble to divert solar wind around a plant behind it. Also we would need to have this thing attached to a massive counterweight and sitting between the Sun and Mars such that the immense drag generated by the force acting on the solar wind is balanced by the gravitational tug trying to pull the thing towards the Sun.

Hydroponics relies on a nutrient solution that feed root systems directly, bypassing the need for soil.

The way you'd do it is to vary the strength of the magnetic field in different areas. The magnetic shield is in effect a giant magnetic sail, so by ramping the power up or down you can adjust your acceleration away from or towards the Sun. You can also reduce or increase power asymmetrically to have the effect of "tilting" the electromagnetic sail and shunting more solar wind mass off to one side than the other, providing the station-keeping thrust that you need. This would be a huge piece of infrastructure and you're right that needing to shuttle propellant up all the time would be a shitty and expensive solution. If anything the structure would have on-board electric plasma propulsion systems (maybe even fusion if we get to that point, the mass budgets won't be prohibitive either way) but only as an emergency measure, for example if the main electromagnetic field failed for whatever reason and they needed to push the entire structure closer to the L1 point to prevent it from falling towards the Sun in an elliptical orbit.

Like nothing on Earth, which is to be expected.
Soil minerals are for the most part different, atmosphere will be totally different, water cycle will be different, weather patterns will be different (no massive oceans to supply humidity and heat to stabilize rainfall patterns), etc etc.
As Mars' atmosphere is thickened and temperatures rise, the lowland areas will begin to see surface water flows for the first time in billions of years. However since Mars has such a massive terrain scale height what we will probably see is the migration of water ice from permafrost underground to the surface as high elevation frost deposits, as humid air from the lowlands is blown over the highlands and freezes out. Eventually as more air builds up these frost glaciers would also begin melting rather than sublimating, which will allow the formation of glacial streams that will flow down and likely join into decently sized rivers of water, carrying salts and soluble minerals down form the highlands. These mountain rivers will almost certainly not terminate in lakes, but instead will fan out across wide areas of the northern plains until they evaporate or soak into the ground. The result will be the formation of large fans of sediments deposited by these rivers, fringed by huge salt deposits. If we are also adding water to Mars/digging it up out of the mantle, increasing the hydrosphere mass, eventually the amount of water circulating will exceed the level necessary to form large ocean-like reservoirs of water, which will slowly become more salinated as the water cycle continues.
To a degree the scale height will always be an issue on Mars; if we assume 1 bar of pressure at the Martian "zero" elevation level, then most of the southern hemisphere and especially the Tharsis region will be effectively uninhabitable to unprotected humans. This will have permanent and unavoidable effects on climate, though not necessarily unmanageable ones.

It changes the conserved value from mass-energy to mass-energy-information which is where the thrust comes from - by hiding information from an object you cause a release of energy to keep entropy from decreasing. The potentially worrying thing is that information is frame dependent so you could theoretically use a pair of quantized-inertia thrusters to spin a generator that produces more electricity than is needed to power the thrusters - an overunity "vacuum energy plant" - and moreover do it in a way that fits inside a spacecraft.

TSTO is optimal for launch to LEO, and modern rockets have enough performance left in the 2nd stage to get payloads well on their way to geostationary orbit (some TSTOs have enough performance to put multi-ton payloads directly into GEO).
Saturn V was almost a TSTO but it needed to be a 3 stage rocket anyway for getting big payload to the Moon, so they inflated the third stage and used it to reach orbit, meaning it was two stage to 1km/s shy of orbit, and with the third stage got up to ~11 km/s final velocity.

You need to make a magnetic bubble as big as a planet in order to shield a planet behind it, anon. The ONLY way to do that given a certain maximum surface tesla value for your magnet is to make your magnet extremely wide. This is because like gravity, magnetic field strength drops off with the square cube law. You NEED a magnetic bubble ~3000 km across, minimum, and to get that you NEED an electromagnet over 1000 km across, using real world technology. It's just the way it is.
Now this magnet doesn't need to be a solid brick of material, it can be a huge sheet of superconducting wire mesh a mm thick with holes a kilometer wide, but one millimeter thickness times several million km of total length equals a very large mass of magnetic array. Now add to the fact that if you don't tether this thing to anchor it in place, the solar wind it is deflecting will cause it to fuck off up to a top speed of around 400 km/s, because deflecting a 1500 km radius cross sectional area of charged solar wind moving at 400 km/s imparts a shit ton of momentum. Therefore, you tie your magnetic sheet to an asteroid that out-masses it enough that even with the magnet turned on at 80% of max power the force of gravity from the Sun pulling on that asteroid can cancel it out. This is where the millions of tons of mass comes from, technically you could use a lighter asteroid but then you need to put it closer to the Sun to get the same force which therefore means a much longer tether with is more difficult to build with non-meme materials.
In fact that last big is all you need to know; even if you could produce this magnetic bubble using something the size of a car that weighed ten tons you would STILL need a million ton asteroid to tie it to in order to prevent this magic magnet from getting accelerated away at dumbass velocity.

Putting hydrogen in a fission reactor ain't gonna do you any good, unless you're talking about breeding tiritium from deuterium and letting it decay, in which case ok go to bed and have enough to send a He-3 powered probe to Uranus in 200 years.
If you want to make He-3 for whatever reason you can do it a lot more easily using lithium and a fission reactor's neutron flux. The lithium process doesn't have a 12.7 year half life like tritium decay.
Regardless it doesn't matter anyway, because He-3 is a very difficult fuel to reach Q>1 with due to its massive temperature requirements for fusion, and if we CAN make a Q>1 He-3 fusion reactor at all, then that same technology would allow us to make a Q>10 D-D fusion reactor or a Q>100 D-T fusion reactor, both of which would be approaching torch-drive levels of thrust power and efficiency.
So basically He-3 would be really neat for building long haul interstellar fusion rockets, but for anything you can imagine doing in-system, D-D and D-T fusion will be orders of magnitude more powerful and simpler.

It needs to be scaled up to a few meters diameter at a minimum in order to keep the neutron flux behind the water curtain, but it'd work

The secondary propellant (pure water) would make up most of the mass flow but was also there to absorb the heat of the plasma and most of the neutron flux, such that the water pressing against the nozzle sides would be about 2000 celsius (the interior of the nozzle would have cooling channels that the water would flow through first before being injected inside to act as the thermal buffer curtain).
>What kind of thrust

"Constant nuclear blast" is too vague and doesn't describe what's happening. A nuclear reactor is a continuous fission reaction held at a certain self-sustaining criticality. A nuclear bomb is a nuclear reactor held at a maximum level of supercriticality for a brief instant, because it blows itself apart. A nuclear salt water rocket is set up so that the fuel (fissionable isotopes dissolved in water) reaches supercriticality after leaving the injection point, heats up to extremely high temperatures, and expands as plasma in the center of a thick curtain of fast moving water. The plasma heats the water into superhot steam, which also expands, makes thrust etc. Anyway the point is that the peak power output of a NSWR is not even close to the peak power output of a nuclear bomb. If a nuclear reactor is like a pile of compost and a bomb is like a stick of TNT, the NWSR design is like a smoldering stack of wet wood.

Orion would have had a sheet of cadmium or some other highly neutron absorbing metal somewhere between the exposed surface of the plate and the crew cabin, so apart form the pusher plate becoming highly activated it wouldn't have been much of a problem for Orion.
NSWR uses a water curtain for cooling as well as moderating a lot of those neutrons, adding boron or gadolinium salts to the water would also make it much more stronger neutron absorbing, but either way the engine itself does not direct neutrons out of its ass at all, they're generated in a spherical distribution. You'd simply have the half of the sphere that the spacecraft sits behind loaded with shielding.

Our observable universe is huge. Monstrously, unimaginably huge. Why should we expect that, even if flooded with space-fairing civilizations, that we would be able to see them?

You have literally no idea what the “points of failure” actually are and how likely or unlikely it is that they are passed. At best, you can claim that life requires the simultaneous presence of carbon, a solvent such as water, ammonia, methane, or a few other substances, an oxidizer for respiration, such as chlorine gas, oxygen, or sulfur, and an energy source like sunlight or chemosynthesis.

Earth is bigger than Mars so it retained more of an atmosphere and it’s magnetic field didn’t die, and Earth had enough water to kickstart plate tectonics unlike Venus. Demonstrating this to be statistically crazy would require direct investigation of many other solar systems, which we can’t do.

If Saturn didn’t form to pull Jupiter back from moving inwards towards the sun then the earth would either be cast out or destroyed. The earth was struck by a Mars sized object at one stage which is why the earth has an oddly large core granting it a powerful magnetosphere, this collision also produced the moon which had proven itself to be very useful.

The earth could have been to small and lost it’s atmosphere like Mars, it could of been hit by some Ceres sized shit rock which would duck everything up, it could of lacked in water or any number of factors could have ruined things for us.

Red dwarfs are universally shit to be around it’s just that some are worse than others and we call these flare stars.

Tidal locking will fuck up your core, which will fuck up your magnetosphere which will get you fucked up. It will fuck up your surface regardless as it takes time for an atmosphere to form and the surface situation will make things near impossible for any significant amount of life.

They (any habitable moon of a large gas giant sitting inside the planet's magnetosphere) would have lots of pretty aurorae. The type of radiation present inside of radiation belts is charged particles moving slow enough to be trapped in a planetary magnetic field, which basically means they get blocked very easily by light elements such as what atmospheres are made of. Of course any aliens there would be in for a bad time if they ever tried to do spaceflight. They would be completely shielded from space radiation though.

HDPE plastics would be better actually, you'd need every exposed surface to be light elements otherwise the interactions of those charged particles with the heavy nuclei of the vehicle is gonna produce the equivalent of a 20,000 lumen lamp blasting your prostate with x-rays. Luckily of course this is a worst case scenario where the home moon is directly in the worst region of a particularly bad radiation belt, and it would only take a few days to transfer completely out of the planetary radiation belt to explore the other moons of that planet, so it's still doable, just a bigger headache. I suppose you could also do it by cramming everyone into an antiradiation bunker (surrounded by 1 foot of plastic shielding and lined internally by 1cm of lead) for the launch and immediate boost away into circum-planetary space, and once the fields drop down to something acceptable you let the crew spread out throughout their ship.

Alternatively they could maybe do that thing where you deploy very long conductors and use a voltage potential to siphon the radiation belts themselves away. You'd definitely run into alien greenpeace screaming about the destruction of the natural auroras with that idea though.

For the sake of argument, I believe that even trying to model something like "how common could intelligent life be" is something that is hard (if not impossible) to model.

Probably in high numbers across the entire universe.
But how do you jump from simple life to consciousness? We don't even know how the jump to multicellular life happened. Much less how apes began to think and become self conscious. Yes we can study things like expansion of cranial sizes in the fossil record. We can look for fossilized cells and try to trace back the jump from single cells to colonies to eukaryotic life to multicellular life.

Is another tech that has to be maintained for future terrestrial settlements. Also when I wrote "maintained" before I obviously meant that it would be improving from time to time.

Don't forget that some point the solar wind is dispersed/disrupted by intragalactic shit enough that it pretty much dissipates even when you don't hit hard heliopause. And it doesn't perfectly coincide with the trajectory to either of the closest stars if you try to travel in the direction opposite to Sol's movement.
