Rocket automation

Single tube rocket fueling
 The screenshots show the refueling of three missiles.

Logic: rocket took off - counter +1. Rocket completely sat down (0 on the scanner, 1 on the memory cell), the liquid shutoff worked. Rocket refueled - hydrogen sensor after the tank reset the cell. Counter works as a divider by 2 (to cut off unwanted unit at rocket launch).

Refueling becomes safe - the tubes don't tear. Ceramics and insulator are not needed. Disadvantage - we lose from 20 (if a chamber is close to liquid hydrogen) up to 200 kg of hydrogen (if far away). And all this with bridges. In principle, there is always 10...20t of hydrogen and 0,1t.- not much. But the perfectionist is indignant... As an option (more cumbersome): you can drain into the chamber and gas back into the cooler:

It has the right to be, especially if the missile is hundreds of meters away.

Simple Rocket Automation
When I see schematics like this (one of the Russian famous bloggers), I get sick:

Therefore, I hasten to present a simple rocket automation scheme.

Plot, for the 1st rocket:

Complete, for 3 rockets:

Thoughts on rocket automatics (imho)

 * Don't touch the gantry. First, 2 gantry(or gantry+ doors) will burn your Conductive wire. Second, there's no point in it. Dupes will sit perfectly fine in the rocket while it's refueling/emptying. Just a switch to let it in/out once in a while is enough.
 * Don't pull the bunker doors over the silo after every rain. No point. Rain scanners and solar panels are elsewhere anyway.
 * No need for launch automatics (wire into сommand сapsule) (except for transport shuttles, which need 2...3 flights in the beginning). You have to change your destination asteroid every time anyway.
 * Well, keep it simple. Simplicity is the key to reliability (not always).

Logic

 * Doors will only open when the rocket is ready AND it's not raining.
 * Doors will open when the rocket returns anyway (so as not to break them out).
 * The gantry rests.

Rocket refueling
I have not yet found a more elegant solution.

If you have one, please advise, I would be grateful.

Scanner placement
The scanner must be away from industrial buildings and other scanners (doors, stairs, mesh and airflow tiles do not count). For 100% quality of scanning, it should be located from them no closer than it is shown on the screen.

But it is not necessary to achieve a perfect scan. Even at 17% scanning quality, the derriere will have time to close.
