THERMAL MANAGEMENT OF A FAST UV SLITLESS SPECTROMETER FOR A METEOR RESEARCH EXPERIMENT

摘要

This paper presents the proposed thermal management design for an ultra-violet slitless spectrometer to be flown on either the Space Shuttle or on the International Space Station as a scientific experiment to capture the ultraviolet spectrum of meteors as they are heated by the Earth's atmosphere. The proposed telescope was initially planned as a Hitchhiker experiment for the Space Shuttle. The Space Station environment is thermally more critical than the Hitchhiker application. The final thermal design is essentially passive; however, heaters will be used to maintain the component temperatures at acceptable levels during telescope non-operating conditions. The major difference between the Space Station design and the Hitchhiker design is the use of external multi-layer insulation and thermal strapping on the former application.
