I don't understand the rules for Deja Vu challenge, what needs to be done exactly.
Please give me the links to some accepted challenges, as examples of what needs to be done.
For example, i have 3 stages of the rocket on launchpad at the start, i launch it, i detach 1st stage and it will land on parachutes safely, then i reach orbit and land with my 2nd and 3rd stages still connected. Nothing is damaged, but what is next? Do i need to simply take off again with these 2 stages, detach 2nd stage mid flight, land 2nd stage safely with parachutes, and simply reach orbit second time with my 3rd stage? Then with second LEO mission is concluded?
Or i can do all that with 2 stages rocket from the start and take off first time with two stages, then land 1st stage, take orbit with 2nd stage, land 2nd stage and take off second time with only second stage and reach orbit again with it?
What means reassemble? Do i have to land my 1st 2nd stage from orbit to some exact place on the planet where first stage landed and connect to this first stage again with connect ports to make a totally new take off with two stages again? So basically i will have SSTO with 1 stage, which has extra useless 2nd stage, to take it as a backpack twice and the idea of the mission is to pick up this backpack after dropping it after first take-off?
