Sorry for interrupting, but do you think a kerbal could stand breathing and performing basic tasks in Laythe's atmosphere WITHOUT a helmet or mask?
There's certainly oxygen in the atmosphere, though we don't really know what the other gases are unless I'm mistaken. But the big thing is probably the radiation. Even with the thick atmosphere, you're going to get significantly more than on Earth due to the proximity to a gas giant. I'm not so sure whether Jool or the other moons would help get the liquid mantle moving (it doesn't get much energy from rotation because it's tidally locked) but if so that could help generate a magnetic field to make it a little safer. Still unlikely you'd want to stay out there for long though.
-
Laythe's gravity at sea level is 0.8g and the atmospheric pressure is about 0.8atm, both are less than Earth and Kerbin
But also a lot more than the Galilean moons. It really is a lot closer in gravity and atmosphere to Earth.
-
I'm pretty sure it just split into a new timestream.
-
That could be an interesting possibility, but Nova said it was a mix of Europa/Io. Basically Europa is covered in ice and probably has huge oceans under it, and if it was a bit loser, the tidal effects from Jupiter would probably melt everything and create a somewhat atmosphere around.
But I get where you com from, your hypothesis is in interesting theory. I wonder if someone who'S better informed on the subject could come add some more information.
But it also has a lot more gravity, like Earth, hence the thick atmosphere.
-
Because the moon looks like a big wheel of swiss cheese.
Nonsense. Swiss cheese wheels look nothing like the Earth moon.
-
If your conditions for something being made from cheese involves mold, then wouldn't Earth be cheese since there is a lot of mold?
Nope, the fact that you can see mold on it's obviously cheesy surface is simply further proof of something I already knew.
-
Clearly, the only thing in our solar system made of cheese is Io. It even has mould. But to say that the moon is made of cheese... ridiculous.
-
Think about it, by the time that any of our probes could get there, we would have:
A. died
B. died
C. forgot they existed, as the signals would take equally long to return, and no guarentee of earth's position then.(Or we died)
The signals would not take equally long to return unless we sent the probe out at the speed of light...

When I talk about space, people are like
"Yeah?... cool.... uh huh... okay... right... I see... cool..."
I don't think they pay much attention.
-
That's the problem, because your moving about with the submarine, meaning if your on the Jool-side of Laythe, your in lower pressure water (the water closer to the surface is pulled more by Jool, slightly, but more). Conversely, if your on the zenith or anti-Jool-side of Laythe, you have a lot more water pressure, as the "rearmost" water is being smushed against the surface. A base itself would "only" have to be strong enough to resist water pressure where it's dropped, as its immobile.
Well, I don't imagine any manned or unmanned vehicle in space for at least a hundred years will be designed to circumnavigate a whole celestial body (bigger than an asteroid). I would expect a submarine would never go more than 100km from the base.
By the way, for those saying that it doesn't matter due to it's impossible density, I'm operating under the assumption that Laythe is actually about Earth sized or similar and that the game is scaled down, which is done for gameplay reasons.
-
Laythe's proximity to Jool. The tidal effect is much, much higher than on Earth.
So far as I understand, the main tidal effect would be that the tide is constantly pulled up a lot more on one side of the moon (due to tidal locking), and in that way isn't really the same as tidal effects on Earth and would vary less widely. I don't really know much about the subject though, do I have something wrong? Are you saying that at certain times the tides will rise several hundred metres or something, making the pressure change? If that's the case, I guess they would just have to make sure the habitat and submarine have decent structural integrity then...
-
Speaking of that radiation. Holy crap! Wiki lists the dose on Io's surface at 36 Sieverts PER DAY! That means you could only stay on the surface unprotected for 40 minutes before you'd get acute radiation sickness and maybe die, not to mention the risk of cancer. That's like standing next to the Chernobyl reactor after it exploded for over half an hour!
Just remember that Laythe does have a thick atmosphere (and we don't know the strength of it's magnetic field but that might help too). So it'd probably be still very dangerous to go out with nothing but a suit for long, but it might not necessarily be quite as bad as Io.
-
you'd need to submerge quite the bit in order to have maximum effect from the ocean shielding.
No you don't... water has a halving thickness of 18cm... A few metres would give perfectly adequate protection.
Why do you need to have a massive submarine? And why would this submarine be so hard to move? We don't have too much trouble with Earth submarines...
I don't know much about tidal pressure changes, perhaps you could explain how this is a serious issue?
-
Why are you building a habitat of lead? You've got massive oceans that don't even need unfreezing right next to you. Either pump water into a thick bladder around the habitat and/or simply have an underwater base! Drop the habitat in the ocean, have an anchor/hook sort of thing at the bottom that can lock you to the ocean floor and pull the base under. Then launch your Laythe submarine to explore the oceans and send a Laythe rover out with a dome full of water to protect you from radiation while giving all on board okay vision. The Rover can be exited through the area underneath the dome if necessary. Plus smaller rovers to go on scouting missions.
And I haven't done the math but there's no way in hell 1mx1mx15cm of lead is 1.7kg...
-
Nobody. Sorry, I mean 'a nobody'. It will be, 95% chance.

v1 = 10x
v2 = 3x
v1 = v2 when x = 0
I didn't mean a single instance where a number they could give would fit into their estimates of each other. I mean this. When Mr Lambert says Mr Verity multiplies everything by 10, this can't be right because we know Mr. Lambert's figures are 1/3 what he means, but that's if you listen to Mr. Verity, except that his figures are supposedly multiplied by 10, so that can't be true either.
I've heard there are magic numbers where they're both right. Obviously, it leads to very nonsensically sized beds but generally speaking solves the issue of inconsistent figures.
-
I think it's be pretty cool to see done. If anyone's unclear on the part I mean, I mean the title sequence with the Moon, Earth, Sun and Also Sprach Zarathustra.
-
You see Mr Lambert insists that Mr Verity gives figures which are 10x the amount he means, whereas Mr Veryity claims Mr Lamberts figures are 1/3 the amount he means. This is impossible! Or is it? Could there be some figures by which they actually multiply their meaning that would make both of their statements true? I'm not a math genius, I don't know. But I'm curious.
-
How about that early bronze age battles revolved heavily around close formation tactics that favored right handed men thus weeding out left handers?
I'm not sure what you're referring to but is there a reason the technique could not have been mirrored? It could have been a way to weed out one of the two hands, but I still wonder if it was just chance or is there some other basis? And the other thing is, do we know if all societies had the same dominant hand that was used in battle formations? If far disconnected cultures evolved right-handed tactics simultaneously, that would suggest some inherent right-handed trend in humans.
-
One thing to point out: You could not have the super-Earth moon tidally locked to both the grandmoon and the grandplanet (that's what I'm calling them because it's adorable
).Wait, if they're supposed to be tidally locked to each other and the gas giant, that means the moon wouldn't really be a moon-moon, it would be another moon at a lagrange point between the gas giant and the larger moon, wouldn't it?
Ah, ignore me, I don't know what I'm talking about.
-
It sounds like a very promising project, but apparently the UK and ESA can be kind of flakey on projects like this. Would hope to not see it fail, or at least complete the engine design. That's always been the idea with spaceplanes, convenient and saves fuel while in atmosphere by using air breathing engines, so I think having them convert to rocket engines partway through is great.
-
When a Mars landing actually happens, I'd bet it would be an international space agency cooperation using a lot of commercial hardware, like stuff from SpaceX. Maybe a few Astronauts from the US, a few from Russia, and some others. An international cooperation major research mission. And maybe some crowd funding could be involved.
-
Which I don't deny. But we only have the theoretical weather systems in place. The point were you have to calculate, there are so many factors just on earth you have to take into consideration. When calculating local conditions over a few days you usually get it right, but here we talk about a global system over millions of years on a planet with different physical conditions. Even our most advanced computers have a hard time predicting what weather conditions are like on earth in a few centuries.
Sorry to butt in, since I don't really know much about meteorology, but for the purposes of science fiction, doesn't there always have to be some sort of unreliable extrapolation? I mean I totally get the desire to make things as accurate as possible, but do they need to be more accurate? I think you kind of have to go with things based on what we know and not completely give up on major ideas because our understanding is not complete enough to confirm that it would work 100%. So long as it is a logical extrapolation of our knowledge to the best of our understanding.
Even with alien life, we might theorise that life is probably not all that uncommon in the universe, to the best of our knowledge, but then there's always that possibility that it really was a crazy fluke and there's perhaps not a single other form of life in our galaxy, or at least the only macroscopic life but that doesn't stop us from creating speculative fiction containing alien life.
-
My hypothesis would just be that it just went one way by random chance and then had a sort of a snowball effect with the slightly more common (by chance) right handers began teaching their children to use the same hand as them until it eventually became biologically ingrained, like an instinct.
).
Is there a possible way in which Verity and Lambert's figures work out together?

Nobody wants to give it a shot? I remember reading that it had been solved but couldn't find the answer.
