It would be neat to have space lanes from produstria to the smeltus and electria "planets".

With krastorio 2 spaced out the 6 loaders and just space in general are a huge limitor and so beeing able to send things down from orbit to provide carbon or iron for steel or oil production would be fun.
(I know you can use circuits to use the same loader for multiple ressources but I like my belts clean and orderly)

Solar power in space on the platform doesn't have to be changed but at least 10% might be nice to avoid stranded platforms.

I know sending a space ship is still insanely much effort, but I think having an autnomous platform in space just doing stuff is always fun.

yeah... no.

I understand your point, but I didn't do that exactly for this reason : having access to easy space travel results in lots of resource that remove the need of using the mod mechanism (harvester) for most basic resources.

Just make big enough / multiple platforms dedicated to specific resources and you'll have ""almost"" the same (minus the efficiency compared to a moving platform) (that's also the reason space platforms are more expensive to craft)

i'm already wondering to add an in-between point between Produstia and the solar system edge, that would only allow rockets (and not railgun, like the current), because once you reached gleba (and did all you need to craft rockets) I feel like it'll be late enough not to cheese the mod

To clarify, I am already building tons of space platforms stationary to harvest ressources from orbit and get iron, copper, steel, coal, carbon as well as red belts and red undergrounds. The use of moving platforms from produstia to the others would be only for additional logistic possibilities for moving ressources to Cargo Landing Pads on other layers (smeltus, electria) without them all having to go through the produstria-smeltus loaders (I know this is a crazy amount of work to go to just not use the loaders but I really need more loader room with krastorio 2 spaced out.
I do still use miners for all the other ressources, like stone, uranium, lava, calcite, scrap and tungsten. (Notably calcite and foundries already provide near infinite iron, copper and steel production already since you can store rediculous amounts of lava and calcite is used only in tiny amounts by forges producing metals).

You are right though that moving platforms in asteroid rich lanes could still make the early/mid game too easy in the ressource gathering area.
However this might be avoidable with specific asteroid densities or other restrictions. For example if a lane only contained medium Ice asteroids farming and defending would be very difficult and inefficient (you can use asteroid chunk convertsion but thats inefficient and at that point you must have vulanus science aka foundries near infinite metal).
0% or 10% solar power already makes early travelling harvester platforms difficult since you either have to provide nuclear power with water/ice or truly truly massive amounts of solar or a lot of accumulators and good circuit conditions. Additionally building larger space platforms is difficult early simply due to all the ressources needed to send stuff into space. I made rarity 3 tier 2 productivity modules for my rocket silo and I still couldent run a rocket silo even 30% of the time.
(Also not sure how much less efficient stationary platforms are compared to moving ones, a stationary platform with 4 electric furnace can run continously producing iron (and a bit of carbon) and its a lot less expensive to build compared to a moving platform)

Obviously in the end this is your mod, personally I really like the dynamic of using the very expensive stationary platforms to free up space on the produstria and the other layers. Especially with Krastorio 2 spaced out vastly increasing the amount of space I need compared to a normal playthrough.

Hell I am such a fan of space, if there was another warp platform layer which was ONLY accessable from space I would use that too regardless of how difficult it would be.

Also do you want anecdotes/balance things of what the mod is like combined with krastorio 2 spaced out, like is that interesting to you, I dont wanna be annoying with potentially irrelevant info.

So, your issue is moving stuff behind surfaces (I thought it was getting the resources actually).

Why don't you use the logistic chests between the surfaces, with logic to automatically set the requester chests to request what is missing in the other platforms ? Wouldn't it be faster than just using belts ?

I'm used to use fast drone mods (alongside with efficient drone mods sometimes), so in my case it was always faster, but with vanilla drones, it may not, i can't really tell.

I'm happy with any feedback :) I don't have the time (and imagination) to try everything that's possible :)

Hmm Ill be honest I forgot that you can set logistic item requests via circuits, though in essence this is preety much equivalent to using circuits with the loaders and just sorting items out on either side, as I said above.

That would definitly work (even without any further increase to robot speed they are already super fast). But I dont really like using bots for all my logistics. I thinks not wanting to overly use bots is a preety common sentiment. Like I wanna work with the difficult space I have and If I just use bots for everything all the positioning and logistics becomes kinda irrelevant. For me it also moves too close to making the layers interchangable since that would make all items transfer between layers in all cases.

Having multiple layers with very different purposes and small subfactories is part of the thing I really enjoy even If I could technically just always put down assemblers with a requester and a provider chest and it would just be better.
