ALL in ONE

Design a rocket that could be built in place inside one of the four bays of the Vehicle Assembly Building (VAB) at Kennedy Space Center, which is 525 ft (160 m) tall. Utilize additive manufacturing (aka 3D printing) where possible, considering which materials might be able to be used and which ones may have to be brought in already manufactured.

this project represent a new kind of rocket combine with some kind of satellite capable of reaching MARS and hold a crew in the cabinet that can turn into a vehicle when it land on the surface of mars.... that vehicle is a lab for recherches and the power is generated by the solar panels...

my only resource is a pain and a few papers :D
