摘要

Third in a series of three Commentaries Week One: The best way to get people and payload to the Moon is a heavy lift launch vehicle. Last Week: The best mission scenario for establishing a lunar base. In the preceding articles, we considered the advantages and disadvantages of lunar mission architectures strictly from the point of view of the lunar base program itself and found that the currently fashionable quadruple launch, quadruple rendezvous plan was inferior to other options employing heavy-lift vehicles (HLVs) to accomplish missions in a single launch. These conclusions, however, become even more forceful when one considers that the president's directive calls for a Moon-Mars program, not just a Moon program. The quadruple plan accepts a plethora of additional development and recurring costs, and mission risks for the sole purpose of avoiding the development cost of an HLV. Yet, since the goal of the program is to get humans to Mars, an HLV and a potent trans-Mars injection stage will need to be developed anyway. So on a cost basis the quadruple plan will lose twice over, since there will be much more hardware to develop for Mars.
