As mentioned by @Infinite Aerospace, Kerbalism support is usually on the part mods side - the PET page has a link to an external Kerbalism patch for PET

Not out of the box - this user found some Kerbalism patches on GitHub for multiple mods including this one and linked it in their post.

DockRotate also has welding - I'm not sure if the end result is the same as Konstruction however. I prefer DockRotate for welding over Konstruction as the rotating feature is something that's better than stock whereas the other Konstruction parts I've never been able to get functioning properly. Very excited about this update!

Not sure, maybe Kerbal Aircraft Expansion and Airplanes plus. I'm not too interested in building planes so don't know much on that front. Are you using CKAN to install mods? Instructions here:

Just one. It's kind of hard to pick when you're starting off but Community Tech Tree is probably the simplest as it just expands the current Tree. I would recommend checking the forum page for each tree to check for supported mods. OPT Legacy, Marv IV Spaceplanes, Mk2 Expansion and Mk3 Expansion. KSP does take up a lot of RAM especially when using mods, I would advise being careful with the number of mods you add or at least be prepared for your save to be cut short because of performance.

ScanSat contracts now come packaged with the ScanSat mod so there is no need to download the contract pack separately. New science tools Kerbalism's Science completely changed the game for me, that and ScanSat are my favorite Science gathering modes. DMagic Orbital Science MOAR Station Science Better colony and space station parts Stockalike Station Parts Redux HabTech2 PlanetSide Exploration Technologies MOAR Station Science Better optimization (for a potato PC) KSP Community Fixes Better tech tree Community Tech Tree Kiwi Tech Tree Probes Before Crew Unkerballed Start QUARTIX/TETRIX/SIMPLEX Trees As a general rule for parts, all of Nertea's Near Future part mods are recommended. There's also BluedogDesign Bureau and Tantares which are incredibly popular but I get overwhelmed by the sheer number of parts there.

@feral_fenrir - It may not be getting regular updates but it works just fin e on v1.12.5. If a mod says it works in 1.8 or above, there's a very good chance it will still work. Contract mods are especially robust in this manner.

Would you please be able to expand on the difference between the two Science configs? I've played both (though not to completion) and from what I can tell Kerbalism SIMPLEX renames some experiment (Telemtry Report -> TITE) and adds a few more probe and crewed experiments? Is that right or are there some more fundamental differences? It's hard for me to pick one in the polls without having a good understanding of the differences. I love the idea of having Radiation and Stress included together - providing an actual reason to have bigger ships like the Hitchhiker Container is my favorite part of life support mods. Sure, I can chuck it on in stock but it actually doing something productive feels much better! Personally, I'm really enjoying the Radiation, Stress and Parts Breakdown mechanics and would rather they be included. However, including them in a "Science Only" config is kind of counter-intuitive - it immediately becomes not Science Only. Though I would argue radiation should be included as (a) the belts look super cool and (b) it's part of science collection with the magnetometer.

I can confirm that a lot of the patches in the first post still work in 1.12.5 even though that post hasn't been updated in several years. I added a bunch to my game a couple of weeks ago and they've been working very smoothly. There is also this:

I believe purple is the body's sphere of influence and green is the resonant orbit.

Ah I thought it was a variable in the config file but turns out it's in the .cs source files! Welp, no idea how to edit and/or compile that but I've been meaning to learn more about it anyways! Thanks for the information.

It can cost money? Would you please be able to point to where/how this can be done?

It would be helpful for the modders to include log files when you report issues as that's the only way they can assess them (instructions here). The mod "PEAR" here has similar (though not identical) functionality.

Huh...I've tried a bunch of different combinations (pure stock, restock only, restock+, stock+multiple WBI mods) but never got it loading. Bizarre. Maybe my test install has just gotten borked in some way from installing/uninstalling mods. Thanks for checking.

Ah, that makes sense, cheers! Only slightly off with my numbers I got curios about what 5061 HG-5s look like...got to 1950 before boredom and uncomfortable noises from my PC stopped me.
