[i-make-robots]

TL;DR
Play the rocket animation in reverse. Reclaim most of your rocket cost, -fuel.
What?
lowers to-launch cost permanently. Must come after rocket launch. Therefore could be unlocked with space science.
Why?
If we can do it, Factorio person can do it.

imho landing is cooler.

Besides! It's a reward for people who keep playing after the official end. Ever play a super mario game made in the last decade? the "win" screen is in the middle, there's still so many challenges left to play.
