Space transfer vehicle concepts and requirements study, phase 2
This final report is a compilation of the Phase 1 and Phase 2 study findings and is intended as a Space Transfer Vehicle (STV) 'users guide' rather than an exhaustive explanation of STV design details. It provides a database for design choices in the general areas of basing, reusability, propulsion, and staging; with selection criteria based on cost, performance, available infrastructure, risk, and technology. The report is organized into the following three parts: (1) design guide; (2) STV Phase 1 Concepts and Requirements Study Summary; and (3) STV Phase 2 Concepts and Requirements Study Summary. The overall objectives of the STV study were to: (1) define preferred STV concepts capable of accommodating future exploration missions in a cost-effective manner; (2) determine the level of technology development required to perform these missions in the most cost effective manner; and (3) develop a decision database of programmatic approaches for the development of an STV concept.

Common manned module
An economic analysis examines a reusable single crew module to reduce the cost of Moon to stay exploration by 5 billion dollars. Topics covered in viewgraph format include the following: aerodynamics, weight, runway landing, technology support, and common module reentry requirements.

A space transfer vehicle for lunar missions
Two 'low profile' strategies for supporting the lunar outpost concept developed by NASA-JSC Planetary Surface Systems are examined. The first strategy involves the design of missions that require only a single launch of a derivative 'National Launch System' (NLS) vehicle. The launch capacity of the derivatives range from 80 to 140 percent of the Apollo/Saturn capacity and use only conventional cryogenic or stable chemical propulsion. The second strategy involves the design of missions that only require the currently planned NASA NLS vehicle to be built. This strategy uses either one or two launches with an earth and/or lunar orbit rendezvous for stage assembly. Advance propulsion concepts, in addition to cryogenics, for the translunar injection stage are addressed.
