Research overview:
Because coolant must be stored, ordinary infrared satellites have the following drawbacks: (1) A large-scale telescope cannot be mounted. (2) Long-time integral observation cannot be done. To overcome these drawbacks, this study examined on the feasibility of a next-generation infrared astronomical satellite having the following features: (1) Reduction of the satellite weight by applying coolantless cooling with a mechanical refrigerator. (2) Long-time integral observation by entering the satellite to L2 point of the solar-earth system. Satellite having these feature can mount a telescope than larger than that on ordinary satellites. In 1997, technological feasibility of the coolantless cooling system was examined.
