An orbital servicing concept, especially for Columbus, based on an Ariane 5 logistics vehicle (ALV) is shown to be feasible. The ALV concept meets all the performance requirements, including safety for transporting logistics resupplies to the space station elements. Deletion of the ALV capability to perform active proximity maneuvers greatly reduces system complexity. Replacement of a large mono tank by separate tanks increases overall safety, deletes tank emptying operation, and the need for additional tanks. The separate tank concept reduces overall height of stage with associated mass savings on the interstage. The propulsion stage proposed can be used as basic stage for all Ariane 5 applications using 20 kN engine together with 2, 4, or 6 tanks for LEO-GTO missions. Attached pressurized module downloads must be returned by STS. The ALV offers very large free capacity for accommodating all types of expendable equipment, trash, waste products for atmospheric burn-up. Pressurized cargo modules were designed for worst case docking to the space station (180 days) offering pressurized storage capability, or umpressurized CM operating as tank farm.
