Speaker Christian Zschoch from Projekt Spaceship, Germany, shared his latest spaceship design concept on the final day of the Asgardia’s Space Science and Investment Congress.
The spaceship envisioned by Zschoch works in two gravity directions. The basis of the construction is a pressurized spaceship hull in a disk shape with diameter of 10 meters and height of 3 meters. If a mission lands on the terrestrial body, passenger will be able to walk on the lower side of this disk. If the spaceship is in outer space, the disk can rotate around its central axis providing the crew with artificial gravity.
‘The compact spaceship body and its multi-directional gravity design allows a direct usage on planets or moons, but, furthermore, the generation of artificial gravity without moving spaceship parts. Navigation along the rotation and acceleration axis has been enabled,’ Zschoch explained.
According to the design, the disk is divided into two corridors, the inner one and the outer one. The outer corridor of the disk is divided into 8 segments like a pizza. Six of them are designed to be planting segments with vertical hydroponic planting racks, another one serves as a laboratory or a living room, and the last one is an airlock.
The inner corridor is occupied by a bioreactor-fuelcell unit, where biomass degeneration in combination with submerged fuel cells and steam condensers provide fresh water, heat, electricity and enriched nutrient solution for plants. Only the front area of the corridor provides space for navigation room.
The cavity surrounding inner hull, 10 centimeters thick, enables a heat circulation flow based on air and water. Water can also be used to increase the radiation shielding and to dispatch externally provided radio-isotopic heat.
The spaceship is equipped with 4 engines, they could be conventional rocket engines or ionic thrusters, depending on the trip. Moreover, the same engines but in vertical position can control the spaceship rotation.
The initial calculations were made for only one person, but Zschoch suggests that two people can inhabit the spaceship, it would just require more plants on board.
