The goal of the MAIUS-1 sounding rocket mission is the realization of the first Bose-Einstein-Condensate and following atom interferometry measurements in space. The hardware of this experiment is specifically designed to match the requirements of a sounding rocket mission. Since the different techniques to create a Bose-Einstein-Condensate like magneto-optical traps and the following atom interferometry methods are very sensitive to external magnetic fields, a effective magnetic shielding is necessary. In this work the design and also the magnetic properties and flight-readiness test procedures are described in great detail. The three-layer magnetic shielding provides a high shielding effectiveness factor of S 1000 for an undisturbed operation of the experiment. With this magnetic shielding it was possible to create the first Bose-Einstein-Condensate in space during the flight of the MAIUS-1 sounding rocket
