No, but that's mostly because they're stuck in the same unimaginative rut they always seem to be. I'm actually starting to think that SBSP is lot more viable than people give it credit, but the plans always fall apart because people are fixated on following O'Neil's vision of massive monolithic solar arrays in geostationary orbit. Europe seems dead set on following this just like they felt that a crew transporting spacecraft had to be a spaceplane or that booster reuse had to involve rockets with wings and jet engines added to them. SBSP has difficulties, but Europe isn't imaginative enough to solve them.

Anything is cheaper that you can launch in one functional piece. Anything that you need to send people up to assemble by hand is almost certainly not economically viable. The European plan is talking about replacing astronauts with “autonomous construction robots,” but I don't see that bringing costs down any time soon. Rectennas don't really care what direction the microwaves are coming from, so having power come in from a number of angles wouldn't be an issue.

Also, if you’re using a constellation you can avoid having to go out to geostationary orbit altogether. A SBSP constellation could use a Tundra or Molnyia orbit just as long as enough of its birds are above the horizon at any one time. Launching to a highly eccentric polar orbit is a lot cheaper than sending an equivalent mass out to GEO, and it makes disposal of them at the end of their lifespan something other than an unsolved problem. Power transmission would be over a shorter range and could probably be done with lighter (and therefore cheaper) equipment.

With the right satellite design you could get a SBSP constellation that isn't much more difficult to build out than something like the Galileo constellation. It’s still a dumb idea when you’ve got the option to just build more reactors but it’s not a completely stupid one.

Or you could do experiments on how animals react under a variety of gravity levels. Perhaps using some sort of ISS Centrifuge Accommodation Module built with the express purpose of doing just that. Such a thing would provide some of the most valuable information you could obtain in a LEO laboratory and answer many questions about the effects living under less-than-Earth gravity has on the body. It's not like NASA would cancel such a valuable module after it was already mostly built right?

That would be good for large areas that you want to expand into while your colony is still economically dependent on Earth or where terraforming is impossible like on the Moon or Mercury
Mars would be less costly to terraform rather than completely paraterraform since what's stripping its atmosphere is solar wind and a 1 tesla plasma magnet barrier at L1 would preserve a thick enough atmosphere to breathe (provided the right mixture of gasses for that pressure) would be much less costly than every kilometer being a giant tent post across the planet
It would work for the Hellas Planitia crater as a colony site/research refuge to adapt plants and animals into a correct ecosystem for when the actual terraforming is at the right phase

Nope, paraterraforming every square inch of Mars would require thousands of times less effort and resources than terraforming the outdoors.
Blocking solar wind won't stop the Jean's Escape mechanism from allowing gasses to escape Mars.
Blocking the solar wind won't magically create new gasses to add to Mars' atmosphere, we would need to extract gasses from minerals in order to build up the atmosphere enough for liquid water to exist.
Simply having enough gas pressure for liquid water isn't good enough either: Mars today has a partial pressure of CO2 so high that even if you only added nitrogen and oxygen, the resulting 1 bar atmosphere would be toxic to humans and most life. We would need to pick a huge source of nitrogen in the solar system and import several quadrillion tons of the stuff, plus capture most of the existing CO2, plus release a shitload of oxygen.
Terraforming is not worth the effort. It's an insane level of resource devotion for hundreds of years at minimum before you see any significant benefits at all, and thousands of years to get to a habitable outdoor space. Meanwhile paraterraforming of the entire surface can be accomplished with no imported resources. Furthermore, working on paraterraforming would get you large amounts of fully habitable area on a time scale of years and decades, whereas terraforming would require continuous efforts to be put in by people over their entire lives with no tangible benefit to them or their grandchildren. Even if a Mars civilization started off wanting to terraform, two or three generations of living inside pressurized habitats anyway will have that civilization say "fuck that, the first colonizers were Earthers anyway and retarded, we paraterraform everything now".

There are these new self replicating things that convert CO2 into O2 using only sunlight and water on planetary scales, they're called plants and they need a lot less oxygen and resources to thrive than a planet sized tent does, and can convert such an atmosphere in 4-5 generations when seeded and managed to self sustainment

You only need 3% partial pressure of nitrogen for nitrogen fixing bacteria to do their job and sustain a biosphere, animal don't need nitrogen from the atmosphere to breath as any diver will attest

The majority of the bloated budget is the labor force to support any operation of facilities at all, and most of the time they have little to no manufacturing work to do. Give them work and the man-hour and facilities overhead to amortize goes way down.

>they're called plants and they need a lot less oxygen and resources to thrive than a planet sized tent does
Incorrect, pressurizing a 200 meter tall tented structure to 1 bar of nitrogen oxygen gas mixture requires much much much less mass of gas per square meter of land area due to the pressure coming from the mechanical strength nd weight of the tent canopy rather than the weight of a column of gas in 3/8th's Earth gravity.
>and can convert such an atmosphere in 4-5 generations when seeded and managed to self sustainment
No, they can't, and you would need to be a retard to think that's true.
>You only need 3% partial pressure of nitrogen blah blah
Sure but you need an inert buffer gas in your atmosphere mixture. You need roughly 1 bar of pressure and you need no more than 20% oxygen partial pressure.
>Paraterraforming gets fucked on planetary scales from being a resource sink, having to watch for every fist sized meteor and risk getting hall of costed by your own heavy industry
It's much less resources and less upkeep than terraforming, and you don't need to give a shit about meteorites, you are living in billions of interconnected pressurized spaces, people will always have plenty of options to evacuate to, either to adjacent habitats or into pressure shelters built inside of larger outdoor-mimicking structures. Bizarre that you would bring up industrial effluent gasses, sinc ein terraforming those are going straight into your breathing air no matter what, whereas in paraterraforming you just do that shit on separate air systems and/or vent outdoors where it has zero effect on health.

Putting all of Earth's air on Mars would result in a maximum atmospheric pressure of about 1.4 bar at the bottom of Hellas basin, with roughly 1 bar across much of the rest of the surface, with the highland areas being so tall that they would still have atmospheric pressure values much too low to support life. Mars needs a shitload of air to terraform due to its low gravity, and the crazy terrain scale height differences on Mars mean that even if you could magically give it the most ideal atmosphere imaginable it would still be pretty inhospitable across over 75% of its land area.
Meanwhile if you paraterraform, every habitat is a comfortable place to live with ~1 bar pressure and nice temperature and humidity conditions year round, however you decide to set the dial. Truly, terraformers have put ideology and their own earther affliction before rationality.

Spin gravity research proving that a cure for zero-G wasting isn't needed would nonetheless pull the rug out from under everyone who's career has been heavily focused on curing zero-G wasting, because suddenly people who plan missions will say "and here's where we will put the tether that lets the vehicle spin to make 0.75g for the duration of the transfer, better budget in $150 million for the system hardware" rather than "and as soon as we have the ability to keep people healthy for 36 months of zero G exposure we can think about doing Mars missions, better spend more billions researching that".
Engineering solutions that we know we could easily build are far less risky than dumping funding into an endless research pit that's trying to suss out so many medical problems all at once and understand the deeper mechanisms behind the effects well enough to provide an effective means to avoid them.
The engineering complexity equivalent to solving zero G wasting in humans is trying to develop a fusion propulsion system to get people to Mars and back more quickly. Huge risk of funding going nowhere, huge leap in capabilities required, and in both cases the problem is solved by simply avoiding spending much time in zero g.

That's if you magic a perfect, breathable atmosphere into place on Mars. Any real life effort would result in worse habitability. Also, by "hospitable" I meant "you are neither dying of oxygen toxicity due to breathing pressurized air nor suffering from altitude sickness due to rarified air". You'd still be in a harsh landscape of minimal water and cold temperatures. Think of it being like the Gobi desert but with less gravity.
It's easy to imagine it would be very dry in those areas of "nice" atmospheric conditions because bodies of water will exist at low elevation, so humid air needs to blow uphill to reach your position, and as air rises and expands it cools off, meaning most of the moisture rains out before it ever gets to you. Since Mars has an enormous scale height and not much water, the lowland areas will get rain and will be fed by short rivers running off of the sides of the Tharsis region and Elysium Montes and the edges of the southern highlands, resulting in several narrow bands where there would be decent rainfall and water availability, but most of Mars would remain a thin-air desert.

That's literally what I said. Not only is there no political will for spin gravity experiments, there IS political will for the exact opposite, ie avoiding researching spin gravity in order to protect one's vested interest program or technology.
If we have spin gravity there's zero justification for waiting for more advanced propulsion tech to go to Mars. If we have spin gravity there's zero justification for continuing to spend billions to research the effects of zero G on health and try to find solutions, because we'd already have a solution. Hell if we start using spin gravity on vehicles we really don't need to worry about long term zero G effects ever again, which makes it even scarier for anyone who's currently 20+ years into a career studying zero G health effects.
Think of it as being closely analogous to the whole reusable rockets thing. Every established member in the industry wrote it off as impossible to do economically and justified their own ways of doing things to no end. Along comes SpaceX and they build an economical reusable rocket and now they've won the market. Oops, all those established industry players are now being forced to either adapt or become irrelevant, and they're so far not doing so good of a job adapting. It's like that, but instead of juicy launch contracts, it's juicy research funding at risk.

Paraterraformers would take over the entire planet eventually anyway. A tented structure where it's big enough to be naturally windy and rainy, is 20 degrees inside, and humid enough to actually grow plants is better to live in than outside where it's -15 celsius at night in summer and dessicatingly dry all the time. The comfortable living conditions and controlled environment farming result in much higher productivity per square kilometer of inhabited land, meaning paraterraforming nations utterly out-compete outdoor dust dwellers economically, and the dynamic becomes similar to that of industrial agricultural societies versus hunter gatherer natives on Earth. Give it 500 years and dusters on Mars would be similar demographically and culturally as native americans are in the modern day USA.

Try to get funding for a single Falcon 9 launch that sends up one module that connects to the F9 upper stage via a 500 meter tether and rotates around to make ~1 g, and contains several living organisms of various description. Go ahead. Total proposed budget: $100 million. Potential result: turns out spin gravity means that plants, insects, reptiles, birds and rodents are all capable of growing normally and reproducing normally under those conditions. Implications of results: Humans living in a spin gravity environment can live their entire lives in space pretty much anywhere we can build a rotating space habitat of some description, be it a 6m wide and 6m tall module on the end of a tethered counterweight in low Earth orbit or a gorillion ton cylinder habitat in orbit around Eris.

And congress decides NASA's budget based on where and how money is being spent, ie, if they have a research firm in their district that has been funded to find ways of reducing bone and muscle loss in zero G. This is not a hard concept to understand and it has 100% been the case for every other piece of space-related funding since the 60's.

Tethers really don't do the Janibekov effect as long as the widths of the objects at either end of the tether are not significant compared to the length of the tether. Even so, it's not hard to design a tethered system that rotates only through the third axis (greatest moment of inertia). If it's rotating through the third axis, it's completely stable.

After this many decades we're all well acquainted with exactly how many hazmat suits you need to wear to safely work with hydrazine. The issue is it's more expensive to pay a dude to work in a hazmat suit than it is pay him to a work in a sturdy pair of gloves. And that's not even getting started on the headaches that come from dealing with OSHA and the EPA. HTP/RP1 is fairly light on the compliance paperwork side, and that's savings can get passed on.

Germany is the sole responsible for the energy crisis in europe. They relied on the baguettes to provide consistent baseline energy and exporting all of it, so they had very little expenses and cheap energy, and they're the ones that were sleeping in the same bed with russians (with their old prime minister getting into gazprom administration one year after his mandate was over lmao). Now frogs have most of their NPPs offline and g*rms' renewables are at a minimum since 2018. Without LNG most of their economy is fucked.

Natural gas to coal? If it's a gas turbine it's not possible, if it's a thermal plant (ie, natural gas burning to boil water) it would take a few months to bring in the coal furnaces and ash conveyor systems.

Depends. With a maser while on the Moon's surface? Could be a good way of quickly sintering lunar regolith.

To me it's not new information but it's informative and well presented so I thought it might interest other anons who perhaps aren't aware of the inner workings.

Laika unironically won the space race. Imagine, thousands of years of civilization on the backs of billions of people who lived in horrendous conditions, to progress to the point where man could reach orbit, and instead of risking one more life they sent a d*g to take such a historic accomplishment. Fucking Soviets, they've cucked themselves and all of humanity.
