The proposed Fuji design was a modular spacecraft (similar to the
Gemini,
Apollo and
Soyuz spacecraft), with various configurations filling different roles.
Minimum System The Minimum System configuration of Fuji was essentially just a
reentry capsule with a
human spaceflight endurance of 24 hours. It was scheduled for development at the early stage of the overall project. This minimum system was called the Core Module (CM), and was to be a
cone-shaped module with a diameter of 3.7m, gross weight of 3 tonnes or less, and room for a crew of three. It was to have thrusters for attitude control and a
rocket engine capable of producing a small amount of thrust. The targeted manufacturing cost was to be about ¥800 million each.
Standard System The Standard System was designed to be capable of one month long flights and flights into lunar orbit. This system was to consist of the minimum system and two additional modules, an Expansion Module (EM) and a Propulsion Module (PM). The EM was envisioned as a living space for long-term space flights, roughly similar in purpose to the
Soyuz spacecraft's Orbital Module (OM). The PM had rocket engines to facilitate orbital adjustments, and a
solar cell paddle for production of electricity.
Economy System The design of the Economy System sought to lower the cost of
space travel, and was based on the Minimum System. This system was to be a low cost version of the CM, capable of carrying a pilot and four passengers.
Other modules Additional modules were planned, including a Space Laboratory Module equipped with a heat radiation mechanism, a
Robotic arm module, and an inflatable Simple Life Support Module. ==Features==
