Seems like that would make people *more* inclined to reupload his work.

That sounds about right. That's ~1/10 the Isp of the Daedalus engine, or ~1/5 the dv listed for the craft, so the freighters could make a few trips like that before returning to Jool for fuel. In practice, there was no need for me to travel that fast, so I often traveled slower, maybe like 3 months. That way I wouldn't have to watch my fuel as much.

Oops, I fixed that quote you mentioned. Guess I'm still getting the hang of things. Yeah, I tend to get carried away with those XD. I'm a hard sci-fi nut and I think it bleeds into gameplay. The game tends to force you to clarify things you don't see otherwise. The thing about mining Urlum is actually an idea put forward by project Icarus and it just so happened to conveniently solve the problem I was running into while trying to increase fuel production: https://www.centauri-dreams.org/2011/06/01/starship-fuel-from-the-outer-system/

Hi guys, I'm the one responsible for this mission. Great to see this is getting a wider audience on the KSP forums! I'm open to questions in case anyone wants to do something similar. There's lots of things I had to work around to get to this state, and there's lots of things I'd do different if I had to do it again. I think it's important to note I used a slightly modified version of Extraplanetary Launchpads - I had to make a new part to enable autonomous construction. You can see that part's config file in my pull request here. I originally intended to use the Civilian Population Mod to achieve autonomous construction. An earlier version of CPM offered a "construction drone" part that could be used alongside Extraplanetary Launchpads to construct spacecraft without having Kerbals on board, but the functionality was never ported to newer versions of KSP. Fortunately, there was a recent change to EL that allowed the creation of just such a part. There were only two problems: 1.) the part would still have to be created, and 2.) the functionality in EL would have to be backported to the version of KSP I was using for my 250 year old save file (v1.2). So I backported the most recent version of EL and recreated CPM's construction drone using the mesh from earlier versions. This was for my own personal use so I still haven't bothered asking anyone for permission. For part settings I copied most of the values from the EL workshop, with the exception of productivity, which I lowered by a factor of 5 to balance for the fact the part didn't need Kerbals on board in order to work. In other words, this playthrough's very existance relied on me modding the game. So I can never really claim it's a "legit" playthrough. There are plenty of other hacks I had to pull anyways (documented here) but it's probably the best a player can do at this point while conducting a mission of this kind.
