So I made a rocket that can do the challenge
Now gotta figure out how to lift it into orbit (weighs 1700 tonnes) View attachment 84380
Sure it's not the prettiest rocket ever made but it should get the job done
Also Mooncrasher, are we allowed drain the fuel from the pod for a softer landing?
There's nothing stopping you from doing that, just remember to keep track of everything so we can tally up a total liftoff mass.
So you'll need more launch screenshots, but aside from that go ahead.
Edit: In this case I'd consider optimising your rockets so that the total mass doesn't get HUGE.
