I was searching for a way to send signals from Luna to Nauvis for material requests as I like to tinker with circuitry and thread https://mods.factorio.com/mod/LunarLandings/discussion/670008980afba141732b9bec mentioned AAI Signal Transmissions.

The mod loads and research is available at blue science but requires processing units to craft the machines (unlocked on Luna). Consider changing this to advanced circuits?

Just as I finished writing this I realized you unlock blue circuits fairly fast after launching your first few rockets and would only require sending a couple rockets worth of raw resources. The mod could still be added as an optional dependency, I had to dig through threads to find this mod as an alternative to single-item rockets.

Yeah I don’t think the recipe needs changing, and yes I’ve been meaning to add it as an optional dependency for a long time anyway, so will get around to that at some point. I suspect, however, that you’ll find multi-item rockets far from ideal even with the signal transceivers.
