Abstract—The state of the art report on Terramechanism on Lunar Soil Simulant are the prime need of the hour in the field of space research programs. The prime objective of the paper is to bring out the research significance on Terramechanism. A comprehensive summary of the researches carried out on wheel-soil interaction in the past decades is presented. The paper highlights the concepts of drawbar pull, torque, slip, slip-ratio, sinkage and compaction resistance which are significant in predicting the travelling performance of the vehicles on the soil. The paper portrays vividly the wheel-soil interaction mechanism between lunar soil simulants and vehicle wheels.
