High Gravity Landable Planets disembarking from ship on Foot.

Jumpin' Jack Flash · Mar 31, 2023

Hi all

Just a quick question, while out exploring I've come across landable planets with high gravity which won't allow me to disembark on foot.
I can use the rover to get about, but is there something I can do to modify my space suit to allow me to do this?

What is the maximum gravity that allows disembarking?

Max walkable g is 2.69. Everything above is impossible. No upgrades or whatsoever will change that.

Oh my!
I've just realised / found out that I more or less asked that question a while back on the forum....sheesh, senility's creeping in.

sorry folks.

A bit off topic but...
A day ago in my Asp X i was docked on the carrier in orbit of a 3g planet. Tried to disembark to go to vista genomics but was denied due to 'gravity too high' - Surely in orbit on a carrier gravity is zero. Is that a bug?

Well, technically speaking there's a difference between (no) gravity and weightlessness.

I don't know if the game makes that distinction, though.

Do FCs actually orbit planets, or do they hover?

If they truly orbit, then not being able to disembark is an oversight.

I have had the same message several times after landing on my carrier when orbiting ringed gas giants, just changed into a miner and sent carrier to one of the orbiting moons, done a bit of mining and then cashed in before setting of exploring again.

If memory serves, they're actually in a fixed position, so yes, they hover. At least, back when I had an anchored fleet carrier. Could even call it a geostationary orbit, but personally, I've never measured if the carrier really does orbit at the necessary height. I don't know why Frontier decided to make them this way.
However, they might have implemented it by making carriers actually a surface base, just set to a height level that's far above the actual surface. That would explain why the gravity at surface level would prevent players from disembarking in orbit.
On the other hand, I could easily be misremembering and thus be wrong, and the game just mistakenly checks the surface gravity for disembarking.

Hm, question. Does anybody know if the derelict megaships, like the Zurara or the generation ships, orbit their planets, or are they in fixed positions as well?

How would one even know? Wouldn't knowing if it's moving relative to the planet's surface require observing for a long time? And even then it would be very hard to figure out if it's actually in a mathematically correct orbit (given it's altitude and velocity).

Is the altitude of the ship shown somewhere (with the velocity and altitude of the ship, and the mass of the planet known one can calculate if it's orbiting or hovering)?

(Edit: Well, I suppose the altitude can be approximated by seeing your own ship's distance from the planet's center. But IIRC that's not given in very accurate numbers.)

FC's do move in relation to orbital stations, but whether that's the station moving or the FC moving or both? The trick would be to place 2 FC's in orbit around a body at different distance from the center of the body and if they are hovering above a fixed position on the surface the distance between the two should remain constant, if they orbit according to orbital mechanics the distance between the two should change over time.

Carrier's also 'orbit' at a different speed to rings (or hotspots in rings).

Yeah, but you have to be careful there. Rings don't act as a collection of individual objects until you actually instance with them, they behave like a solid disk, and because of this the outer edge of the rings appears to orbit much faster than the physics of orbital mechanics say they should, and the inner edge slower, so using rings and ring hotposts to judge the orbital speed of an FC would be highly misleading.

If there's a small ring gap, small enough to fly across in real space, if you fly from the inner edge of the outer ring to the outer edge of the inner ring objects in the ring will appear to be zooming by, until you get close enough to instance with the location of the ring you are approaching, so I don't think we could possibly use rings to determine much at all.

In my experience, FCs do not orbit, they remain static.
Several times I have had my FC parked at a high latitude (esp. evident with ringed planets), and always stuck in that position, which defies the laws of physics.

Just stating what I have noticed

, The physical laws relating to moving objects etc. are above my pay grade, but in game I do a fair bit of mining as well as exploring so fairly familiar with the way things work in certain aspects of the game.

How do you determine this?

If your view of the planet (from your FC) never changes, it means the FC is actually orbiting it, at a geostationary orbit. Of course its altitude (ie. distance from the center of the planet) might be wrong for a geostationary orbit, but how do you determine this?

Should be easy enough to calculate how high geostationary is for a body of known mass and rotational velocity, it will of course be different for just about every planet.

Geosynchronous Orbit (Math) - Kerbal Space Program Wiki

Of course to be geosynchronous you would need to orbit over the equator in the same plane as the planet rotates, but we are assuming that already if our FC's are staying fixed above a surface point.

Yeah, there's also that. I don't think there's any way to determine where the equator is other than observing the planet from a distance for enough time to see how it rotates.

Any tips regarding landing on a high-G planet? 2.45 in this case. I'm in an Anaconda with 5D clean-tuned stripped-down thrusters.

2.45 isn't in a class I would put as really high, 5+ would be high, 2.45 should just need a slow approach and just ease down on belly thrusters, but if you are really worried, just ease slowly along at a very shallow descent angle until you are just above the surface and then drop down to land. You may lose some shields but you will get down fine. 2.45 is, or should be, relatively easy, just don't thrust downward with any sort of....vigour!
