Once you can produce copper in space make a few platforms small enough to build space foundation. Just let then cook while working on other stuff. Having a bunch of foundation you didn't have to launch is a huge time saver.

Be careful of stack inserters with things that can rot. If the stack rots before it's full the inserter won't take new items and won't put the rot down locking the output.

When creating space requests you can specify what planet to get them from.

To keep fresh bitter eggs and prevent hatching harvest them into a supply chest. Then set a inserter to remove if quantity is greatest than x take oldest first. I use 100 per nest. Send removed to be burnt. This keeps fresh eggs available without them popping off every so often.
