Abstract:

In this study, the current and expected state of lunar landing technology is assessed. Contrasts are drawn between the technologies used during the Apollo era versus that which will be used in the next decade in an attempt to return to the lunar surface. In particular, one new technology, Autonomous Landing Hazard Avoidance Technology ALHAT and one new method, DIDO optimization, are identified and examined. An approach to creating a DIDO optimized lunar landing trajectory which incorporates the ALHAT system is put forth and results are presented. The main objectives of the study are to establish a baseline analysis for the ALHAT lunar landing problem, which can then be followed up with future research, as well as to evaluate DIDO as an optimization tool. Conclusions relating to ALHAT-imposed ConOps Concept of Operations, sensor scanning methods and DIDO functionality are presented, along with suggested future areas of research.
