This Brief Tech provides a critical review and modernization of the baseline assumptions 
for lunar surface operations originally outlined by Eagle Engineering in 1988. While the 
original framework offered a valuable foundation for early conceptual studies,
advancements in lunar mission architectures, robotics, autonomous systems, and in-situ 
resource utilization (ISRU) strategies now require a fundamental update. The operational 
speeds, equipment capacities, distances, and construction methodologies presented here 
reflect current engineering practice, informed by the realities of Artemis-era mission 
planning, commercial lunar programs, and improved understanding of lunar surface 
conditions.
