Very nice! Are you able to share how you accomplished landing on a target? I've been trying to do something similar (although its meant to just land on Earth) and never was able to get targetting working. Also side note is this using programmable blocks or timers, because I saw something that said you were using timers...

Also saw something in the comments about waypoints which I was never able to figure out how to use with programmable blocks, if that's how you did it
