Hi! I just made this mission without noticing it has a forum, so I share the pictures and information with you. I decided to send satellites to Jool and all it's moon than landing too. I had a core module with Hitchhiker Container, a Laythe lander, a Tylo lander and a main lander which is also used to lowering orbit. There was a command module, attachable to all these modules and with all the science. There were 8 launches from Kerbin and one for a building module only around Kerbin. I had 8 big fuel tanks, decoupled when empty. Due to I forget to balance the whole ship I was not able to throttle with full power. To reach Jool, it took me 6 Earth hours, my computer lagged very, I almost given up. When I entered to Jool gravitation pool, the modules had been rearranged, moved the Taylo lander to the front, while the main and Laythe lander headed to Laythe. Two satellites were release, one of it lost during aero break at Laythe, the other successfully orbited Jool. The core module arrived to Taylo with Jool aero break and sent satellites, replacing the destroyed one and to Vall and to Taylo. Meanwhile I landed then successfully ascended from Laythe, then headed to Vall, with success. After that, I met with the core module, refuelled, than took the Tylo lander to land. Success, and then lift from it's surface. From now on the mission was easy, due to the fuel remained, Bop and Pol is easy to land. I released satellites to all moons and one remained which set to high orbit around Jool. Back to Kerbin and splashed into the water.
