Definition

A summary of required velocity increments across all mission phases, used to assess fuel requirements and feasibility. In this paper, the total delta-V is approximately 5289 m/s for NRHO, 5267 m/s for Halo, and 5244 m/s for DRO modes. Total Earth-Moon round-trip fuel costs are comparable, with the main difference being lunar transfer segment duration.
