ASE 396 - Spacecraft Subsystems Design
4 December 1991
This document describes the preliminary design of the Small Lunar Observer Bus (SLOB) spacecraft. The SLOB is a small spacecraft capable of delivering a single generic scientific instrument into lunar orbit. The feasibility of such a spacecraft is examined as is the estimated cost involved with producing and operating the spacecraft. First iteration designs are investigated for each of the spacecraft main subsystems, with restrictions on vehicle design due to mission constraints being fully considered. Some of the mission constraints included are mission duration necessary for the proposed scientific payloads, presence of the Earth's shadow shading the solar arrays for extended periods of time, and, in the case of investigating the gravity field of the Moon, the need for the propulsion system to fire more than once therefore requiring a liquid propulsion system. Finally, the strengths and weaknesses, as well as alternative designs considered, are examined.
