I’m fuzzy on the details, but it went something like this:
- I set up long resource lines of coal, copper and iron.
- I needed a thing#1 and built a neat little package to build it, exactly to order and on minimal space.
- I copy pasted that design 10 times left to right along my resource belt line.
- Then thing#2 came along. Needed the same stuff and combined with thing#1 into thing#3. So I wrapped my resource belts, designed a second package on minimal space and also copy pasted it 10 times. So I had pairs of thing#1 and thing#2 with a line in the middle to combine them and a belt to collect them. Worked nicely.
Then:
- Coal was replaced by electricity. I had no space for powerlines.
- I got other types of the grab thingies, potentially simplifying my setup.
- Suddenly I got sorting, making my belt setup a waste of space (I had one line per thing/resource).
- All belts needed to be replaced by better belts.
Oh and:
- Thing#4 came along, needing 2 of thing#1 and one thing#2 with some additional resources. Since I built to order, I basically had to start from scratch or severly hamper the production of thing#3. Also, my packages didn’t work anymore without wasting space and/or entirely fucking up resource belt management.
Therefore, I designed stuff from scratch to fit the new requirements.
That’s from the very beginning, but after repeating this pattern a few times, I gave up. Building it non-optimized felt even worse.

There are a few sites like celestrak.org hosting TLEs for all satellites and some debris, which allow you to calculate current and future positions yourself. They are published by NORAD (North American Aerospace Defense Command) since 2003.
These aren’t super critical information. While we know where they are, it’s not always public information what they do exactly.
