Making space science packs isn't exactly rocket science... but maybe it should be.

This mod makes continued rocket launches necessary for space science pack production. It adds the orbital data collector, which must be launched into space on a rocket. Your space platform will then receive the launch data, while you have a 75% chance of getting the orbital data collector back for reuse. Each launch generates 50 units of launch data, which is enough to make 250 science packs, so you'll need to keep launching rockets at a decent pace but small bases won't be too strained.

Logistics requests from space platforms work a bit strangely, because they'll never actually be fulfilled. Requesting launch data won't do anything; you need to request the orbital data collector (because that's what actually gets launched) but it won't ever show up at the space platform. If you're having trouble automating your rockets using the standard systems you might want to try Circuit Launchable Rockets to automatically launch your rockets whenever you specify.
