The small expendable deployable system and tether satellite system programs did not have a uniform written criteria for tethers. The JSC safety panel asked what criteria was used to design the tethers. Since none existed, a criteria was written based on past experience for future tether programs.
This paper presents a Lunar Transportation System (LTS) based on existing technology and liberal use of existing or planned national and international space infrastructure. The objective of the studies described herein was to define a LTS capable of delivering and servicing a manned lunar outpost shortly after the turn of the century. Alternative approaches examined used derivatives of elements from the planned National Launch System or existing international assets to reduce development and launch costs. This study incorporates many design features determined by contracted NASA efforts to reduce nonrecurring and recurring costs for a LTS.
The paper describes a lunar transportation system (LTS) based on a minimum cost approach to the lunar exploration scenario. A three-part exercise was conducted to minimize the cost and risk of lunar exploration, and the results of these optimization studies are presented. Particular consideration is given to the proposed concepts for the translunar injection stages, the common crew module of the LTS, the lander configuration, the LTS performance, and a concept of a long-range rover ('Rover First ') for discovering and mapping lunar resources for future utilization.
