People living on Mars beyond some day far off in the future will only have scientists that run mining operations and will be the only ones ever there, with maybe some tourists.

The bottom line: WTF makes you think we can terraform a dead planet to get away from a planet we can't keep alive? Are you all really that stupid?

Seriously.  All this money being spent, and nobody's done even a single proper serious orbital mice-in-a-centrifuge experiment.  The Japanese did one that I can't even figure out why they bothered with it, given they tested neither lunar nor martian g on the little guys.  So far as I know, that's it.

So we have a lot of data on the effects of medium term free fall on humans, and a tiny bit of data on extremely short-term 0.16g on humans, and nothing else.

Just one proper centrifuge experiment to show you're serious, guys, that's all I'm asking here.

I want to drop kick puppies whenever I see the this trope brought up as to why human interplanetary travel is impossible.  There are two easy mitigation steps, that are way above TRL 1:

1) Mass.  Short of having a front-row seat to an event that can be seen from several galaxy clusters away, there's enough mass nearby to stop most anything.  The two constraints on mass shielding for your trip are the rocket equation and how much it costs to get that mass out of a gravity well.  Both of these constraints become more reasonable when you have a very large, and fully-reusable, rocket.  Galactic cosmic rays are what you need to attenuate; if you're using a high-thrust rocket, chances are you already have a lot of propellant that you can place between your crew compartment and the sun to mitigate solar flares.

2) Go fast.  Less time in transit means less cumulative exposure.  The other nice thing about big rockets is that you can trade payload for trip time.  Sure, you can send 100t on a bare minimum Hohmann transfer.  Or you can trade half your payload for propellant, up the delta v, and, quite simply, go faster.  Try this out in your orbital sim of choice, with various porkchop plot transfer window planners, and see what happens to your trip time when you have delta v to spare.

There's also the option of building a slow, but much more massive rotating permanent habitat and putting it into an Aldrin Cycler orbit.  Once it's going, it requires minimal fuel for course correction, and you only have to get your payload to and from the cycler.  All the energy to move that massive habitat for the trip is spent once, during construction, and 'free' after that.

Now THAT is the one thing I think could be a hiccup for colonization of other planetary bodies.  And I totally agree with the need to do centrifuge experiments at the earliest opportunity.  But I think the worst-case scenario ends up being that colonists simply can't come back to Earth, short of some pretty monumental genetic engineering or surgical intervention.  That's a pretty huge disincentive to leaving.  OTOH, lately, there have been some pretty significant incentives for leaving....

Worst case scenario is that Mars doesn't have enough gravity to trigger the mechanisms in our bodies that keep them healthy, and there's no floor to how badly you can deteriorate.


Prussian_Roulette: lately, there have been some pretty significant incentives for leaving....

Just the opportunity to work on such a fantastic cutting-edge endeavor would be enough.  But while I might be a decent candidate psychologically, physiologically I'm a no-go (age and health) and then there's my wife and kids I wouldn't leave behind.

30 years ago if you'd promised me 75 cubic meters of personal space, and regular upgrades of a computer and data (I'm at 5 TB of movies, music, photos, and text at present) I'd have been happy to move to Mars to do tech support for a science outpost.   Though so long as you're willing to put up with an average 20 minute delay 99% of the work I might do could more easily be done with a cloned setup on Earth pushing updates.  It'd be better to send a guy who's handy with a wrench and a soldiering iron.

I'll concede that, on the Consequences side of the risk matrix, but I think it's a little bit lower down on the Probability axis than it was 50 years ago, due to the aforementioned medium-duration zero-gee experience.  A human lifetime duration experiment really is going to come down to being on the ground for, well, a lifetime.  For a true colony, it'll also come down to the perhaps ethically-grey area of deliberately makin' bacon on Mars and letting that experiment run 'full term'.  Animal experiments in a centrifuge should narrow down that risk a lot, hence my agreement that we need to do it.

I don't think that obviates the need for what's going on in Boca Chica, because it will have many alternative applications, and it gives you the cheap lift capacity needed to put up the kind centrifuges you want for experiments on something bigger than mice.

One of the study's authors, Professor Sayaka Wakayama, of Japan's University of Yamanashi, told The Daily Mail: "Many genetically normal offspring were obtained. These discoveries are essential for mankind to progress into the space age."
"When the time comes to migrate to other planets, we will need to maintain the diversity of genetic resources, not only for humans but also for pets and domestic animals," he added.


All those other farking animals--we have to kill them to get to Mars. It's completely worth it, to kill off everything we have here, in order to do more experiments on humans in space.

I propose that Mars is a slightly *more* harsh mistress.  Practically speaking you'd need to bring your own food, water, shelter and air to either place.  Maybe you could mechanically extract breathable air from the thin atmosphere of Mars, but best to bring your own source of oxy too.

But at least Luna does not have wind storms.

I think the extra g is probably worth a lot more that you're giving it credit for, though honestly I've been in a g-cancelling harness that sorta-kinda gives you the experience of moving in 0.38g and it's already too little to move properly.  You have to crab walk or bunny hop because you don't get enough traction to push against the ground in a normal gait at a reasonable speed.  Mainly I'd (hope) that 0.38g is enough to keep our bones and cardio-vascular system happy, though this remains to be seen.

Also, the dust might be toxic, but it's not composed of magnetically levitated little razor balls waiting to get into every crevice to wear down anything it can rub against.

Then, except when it comes to aerobraking, a thin atmosphere is better than effectively no atmosphere (depending on your definition, the Moon sort of has one, but I don't really think it counts more than technically).  Especially when it means a decent tarp can be pressurized in it.  You're not going to do that when there's essentially pure vacuum on the other side.  And given that the atmosphere on Mars is almost 3% nitrogen... with a bit of work (OK, a lot) to selectively compress the gasses and do some CO2 splitting, you could in theory suck in martian air and create terran air.  Though there may also be N2 bound up in the surface material that could be easier to extract anyway.

The big downside to Mars is the distance from resupply.  For serious emergencies, both the Moon and Mars are too far away for Earth to help anyway.  And the 10 day or so solar conjunction that blocks line-of-sight communications every couple of years is an annoyance, too.

I've always thought of Mars colonization in the same frame of reference as living at the bottom of the ocean. Super dangerous, difficult, expensive, justifiable only for science reasons, etc.

Now do all that with the closest help literally hundreds of millions of miles away.

grinding_journalist: I've always thought of Mars colonization in the same frame of reference as living at the bottom of the ocean. Super dangerous, difficult, expensive, justifiable only for science reasons, etc.


I more or less agree, though attempting a Mars colony (starting with a science outpost) would certainly teach us loads about how to deal with sustainability on Earth that we're obviously not that serious about working on here.

And if we did figure out how to build a self-sustaining colony on Mars, then comes the "don't put all your eggs in one basket" justification, and a bonus of "if you can live on Mars, you're probably not that far away from living in space", which is pretty awesome if you'd like humans to be able to do first-person exploration of the Solar system and maybe throw a generation ship or two into the void some day if we ever find a viable destination through a telescope.

Mars is not lacking Oxygen.  It's lacking free Oxygen, which Earth did not have for roughly half its existence.  And guess what's mixed in with the white stuff on the poles, and what bubbles up in the Martian summer?  Water.  Then there's Nitrogen, in the form of nitrates.  And Carbon in the air.  Releasing everything needed and collecting it takes energy, not miracles.  What's needed for a smattering of dirt-mound shielded cities and a terraformed planet are orders of magnitude different problems; importation from other sources in the Solar System may be needed for the latter but, if you can get to Mars, you can get to those other sources.

Regarding windstorms, that may be a good thing, because lunar dust is basically lung-razors (un-blunted by weathering) that like to stick to everything.  Martian dust may turn out not to be much better, but at least there are abundant gasses and water to clean it off.

Perchlorates become an impediment to Martian poo-tatoes, but that problem may be solved as well.

There isn't enough available mass in the Solar system to terraform Mars.  It's not practical to a degree not just beyond our current technology, but beyond reasonably predictable future technology as well.

And if we did develop the required tech?  We'd be able to do far more interesting things with that mass than terraform Mars.
 
2021-06-13 2:38:25 PM  

Unsung_Hero: There isn't enough available mass in the Solar system to terraform Mars.


How do you figure?  Earth is < 1/400th of the mass of the Solar System, not including the Sun. I'm not proposing we blow up Uranus (thanks, I'll be here all night) to get all those juicy volatiles.  Earth's atmosphere is 5x10^18 kg.  A smallish-TNO, like 58534 Logos, is already about 1/10th of that, and likely is an ammonia-ice slush brick, with some tholins and rock for flavor.

Unsung_Hero: It's not practical to a degree not just beyond our current technology, but beyond reasonably predictable future technology as well.


Again, how do you figure?  If we seriously talk about asteroid and comet deflection to save the Earth from an extinction event, then how is deflecting objects on the same orders of mass into a collision with Mars any different?  Elon likes to brush off nuclear fusion because the largest operational reactor is in the sky but, to his point, the energy is already there, if that's what you want to use.  These are production scaling problems, not physics or mass-on-hand constraint problems.

Unsung_Hero: And if we did develop the required tech? We'd be able to do far more interesting things with that mass than terraform Mars.


Well, yes.  But I would argue that deflecting the orbits of TNOs over decades to centuries is less of a leap than say, self-replicating monoliths to ignite Jupiter and turn it into a mini Solar System.  I could understand why many people may get twitchy when other people start deflecting TNOs into the inner Solar System, but it's not like you wouldn't see an attack coming decades in advance - long enough to both do something about it and nuke the people who did it.

Yep.  Manipulating TNOs is a pipe dream.  And the entire asteroid belt doesn't add up to a decent fraction of our Moon, never mind the difference in mass between Earth and Mars.  And smacking Mars hard enough and often enough to 're-ignite the dead core' would also leave the entire ball uninhabitable for millions of years anyway.

I'm kind of keen on the idea of an artificial magnetosphere using a deflector satellite at a Lagrange point, and then sealing up and pressurizing segments of Valles Marineris and living in the equator-facing walls for the extra shielding.  And it'd look cool, which is an important consideration (of course!).
