Jool Y U no GROUND?

[Tidus Klein]

So yesterday before .22 came out I decided to put a small rover on jool (I know this would summon a kraken but I just wanted to see what would happen)

I do a high speed 9,500 m/s aerobrake and float down. around halfway down I notice that I am falling back in to SPACE? and that there is ground around that space.

I continue down and wind up going in to the negatives I get impatient and cut the last of the four chutes on the rovers decent stage.

I finally manage to blow up at around -500m.

I know jool is a gas giant but there has got to be ground some where! or did my game just glitch out.

Your rover was crushed due to pressure. There probably is a solid surface down there (maybe not in the game, but in the way that gas giants are IRL), but it isn't something that you could call ground and be able to rover about on it.

[Tidus Klein]

NO I fell in to space!

I had the space back drop below me as I fell! SPACE! I saw stars and stuff.

and my blue trajectory indicator went straight to the center of the planet! and loped back up!

I agree that i was crushed by gravity but at -500 I should have see ether ground or more green gas not the black of space!

[Sirine]

dude， is just a game. dev not put It there. period.

[Psycix]

So the only issue here is the camera issue that clipped and did not render the green planet, leaving you with a space background.

They should indeed add some sort of green overlay to the screen when about to be crushed.

Was the blackness full of stars and formed like a Monolith?

[Tidus Klein]

UU it was just a big square of space but if i panned the camera up I could see ground in the distance.

@sirine ya I know but there should be something there.

Not necessarily as it isn't a given that gas giants have a solid* core, though given Jool's role as Jupiter-analogue and position far out in the system (so it's cold) it's certainly likely.

*edited to add; make that "composed of stuff traditionally considered solid" as in, it's stuff that we'd expect to see as a solid (like rock) instead of stuff we'd expect to see as a fluid (like hydrogen); it's all squashed up into a hot mess, but the composition changes with depth.

Previously Jool had an surface, but an very weird one, almost dropped down would jump around and get destroyed so you could not drive an rover where.

This was at -100 meter, in 0.21 this was changed to -500 meter and the visible ground went away so you see space then you get deep.

I landed jeb on Jool in 0.201 and dropped lots of probes down where.

Jool has no solid ground, only a region where it's "game over".

Gas giants don't have solid ground or any seas. They just keep getting denser and hotter, and nothing can survive that. Not even a solid ball of tantalum hafnium carbide could survive the trip. It would melt way before it reaches the outer regions of the core.

I like the fact we've got such place in Kerbol system.

I got impatient as well during my sacrificial Jool missions, i.e. Dropped jeb out of the lander at -300 and facepalmed upon realizing the 'surface' was at -500.

Well, they have a sea of metallic hydrogen if you go deep enough ... which is said to act like a liquid ...

but on the other hand you have to withstand a pressure of 3.000.000 atmospheres to get so deep ...

considering the fact that aleady exploring our own deep seas, which only have 1.000 atmospheres, with robots is a rather risky and difficult endeavour, it is rather not believable for a probe to get so deep, even with technology 100 years in the future

Oh, people will hate me for repeating this, but no. Gas giants do not have liquid seas. The metallic hydrogen is a conducting variant of a very dense supercritical fluid hydrogen. There is no phase border. The fluid (not the same thing as liquid; all liquids are fluids, some fluids are liquids) keeps getting denser until the hydrogen molecular orbitals start overlapping. There might not even be a strict border where the conductivity starts abruptly, but it's probably a transition.

The insides of gas giants can be many times denser than water, but they aren't strict liquids and there isn't a border which you could look at and see an "ocean".

[Tidus Klein]

OK

well I guess Im just complaining now how there is no texture for you to land on(and RELEASE THE KRAKEN!)

ALL questions answered THANK YOU ALL!

And this is why they are called GAS GIANTS.

Not really big planets with thick atmospheres.
