The capsule of “Passepartout II” is a very improved version of the first flight hardware. The structural design has changed from a wood-styropor construction to a carbon fibre-styrodur chassis, which is more stable against deformations and more insulating. Some parts of the flight computer have changed and the software was updated and parts of it were completely new programmed. All hardware components were optimized in weight and are completely new arranged in the capsule. A complete new main power supply was built.

More importance was attached to recover the capsule after landing by having more reliability in the transmission of GPS coordinates by two independent transmitting systems. An improved arrangement of the Track And Trace system will prevent interferences with other components.
