My Question about the new upcoming planets


Grand Lander

Recommended Posts

Since moons don't tend to have an atmosphere, parachutes won't work. They might have a thin atmosphere, but not enough to slow you down enough to avoid crashing. You can land on planets for sure, especially on the ones with a thicker atmosphere, but I wouldn't recommend trying to land on a gas giant, mainly because there's no surface to land on, and because the pressure will most likely crunch your vessel long before you could try to get out.

So for what I know, no moons with atmospheres are added, so you'll have to land just like you land on Mun or Minmus. For the planets, that's a whole new story.

I've created a Curiosity-type lunar lander that hovers in and drops a payload (usually a rover) and then flies away and blows up somewhere since I can't control it/have no use for it afterward. I'm anxious to see the new planets and use that very setup for a Curiosity landing simulation of sorts, parachute and all.

Also hoping someday, I can re-attach separated parts so that hover crane dealy doesn't have to fly off and explode :B

And yeah, what he said. New moons probably won't have atmosphere, but the planets should. At least I hope.

I don't want to land in molten hydrogen.

Actually, Gas giants do have a surface.

I has a gaseous layer, a huge and incredibly deep liquid layer, and then a solid core.

And what is your evidence? Because you say so? Both are acceptable hypotheses, and always, with a statement, give information that supports it. Also, should I say that even scientists don't know? They are not absolutely certain about it, but the most of what I've read state that the core might be composed by molten hydrogen metals and rocky substances.

On topic: Parachutes will work excellently on planets with a thick atmosphere like Kerbin. Eve will be the one that works the best, since it's atmosphere's density is i think five times that one of Kerbin, so it will be perfect for aerobraking and parachuting.

Not in the Kerbal Universe, remember, and either way, the pressure in the core makes the rocky substances melt, so it doesn't have a solid core, more likely a molten one, much like the earth.

I thought the pressure caused the core to be solid, simply because it is so great that the atoms are forced together so close they can't really move.

Maybe not...

The pressure causes the atoms to heat up, therefore melting. Maybe there's a thin layer of solid formation, but my guess is that the very core is molten.

Good job really, seeing as the OP was asking about planets rather than moons

IF you read carefully the OP, he talked about planet and lunar surfaces, so I answered both.

The standard theory is that they're solid, the pressure is too high for it to melt.

Science on this question is still in the question phase. i say this because we simply dont know yet. Juno probe should give us lots data that could lead to an explanation. IMO i think the question is rather tricky, but im going to go with it having a "thick soup" as a core and not it being solid. Im guessing this is because the planet is radiating a lot of heat, and the presence of a HUGE magnetic field like on Jupiter tells me their is a lot of metal churning. If it were just solid, then i would think the magnetic field would be a lot less. thats just my speculation on this issue, here is a journal which kind of supports it.

And to answer the OP question, Yes you will be be able to parachute on planets (Pending the atmosphere thickness) and i think their is a liquid moon that probably has an atmosphere but most of the moons probably wont have one.

I'm going to go to that unheard of step in internet discussions and reference an actual peer-reviewd scientific journal.

From this phase diagram, at any appreciable temperature (even below 0 celsius) hydrogen is going to be liquid at anything approaching the pressures at jupiters core. Even below these pressures, at intermediate depths, I believe the temperature of jupiter is too high to allow for solid hydrogen. Hence, any HYDROGEN will be liquid. Other materials such as carbon or irons coalescing at the core to form a solid core is another matter.

I've been waiting for Juno for quite some time now, I still think that the core will be solid, and that the strong magnetosphere is caused by the spinning core and the metallic hydrogen around it.

No one argued that the Hydrogen would be solid...

His evidence is modern chemistry and physics. You did not give any information to support your hypothesis that it would melt, so why should he. The core would not melt because of the pressure of matter above it, but it would melt because of the heat caused by the pressure. If you look a just about any phase change diagram, with higher pressure comes higher melting, boiling, and sublimation points. So if the pressure was high enough, it would keep it from melting despite the increase in temperature until you got to the critical point. Granted it may be liquid, but your incorrect supporting science invalidates that part of your argument.
