Access to Space: A Strategy for the Twenty-First Century

Access to Space: A Strategy for the Twenty-First Century The United States (US) launch infrastructure is at a crisis point. Human access to space embodied in the Space Shuttle is due to be phased out by 2010. Currently, there are no heavy lift, 100 ton class launchers to support the US national vision for space exploration. Medium and large expendable launch providers, Boeing's Delta IV, and Lockheed-Martin's Atlas V Evolved Expendable Launch Vehicles are so expensive that the Delta no longer carries commercial payloads and the Atlas is unlikely to show significant growth without equally significant cost reductions and commercial traffic growth. This set of circumstances questions US dependence on these launch vehicles for national security purposes. High cost growth also exists with small launch vehicles, such as Pegasus, and the promising new field of small and microsatellites is little developed in the US, while foreign efforts, particularly European, are expanding largely on the availability of low-cost Russian boosters.

Abstract

The United States (US) launch infrastructure is at a crisis point. Human access to space embodied in the Space Shuttle is due to be phased out by 2010. Currently, there are no heavy lift, 100 ton class launchers to support the US national vision for space exploration. Medium and large expendable launch providers, Boeing's Delta IV, and Lockheed-Martin's Atlas V Evolved Expendable Launch Vehicles are so expensive that the Delta no longer carries commercial payloads and the Atlas is unlikely to show significant growth without equally significant cost reductions and commercial traffic growth. This set of circumstances questions US dependence on these launch vehicles for national security purposes. High cost growth also exists with small launch vehicles, such as Pegasus, and the promising new field of small and microsatellites is little developed in the US, while foreign efforts, particularly European, are expanding largely on the availability of low-cost Russian boosters. One bright point is the emerging private sector, which is initially pursuing suborbital or small lift capabilities. Although such vehicles support very limited US Department of Defense or National Aeronautics and Space Administration spaceflight needs, they do offer potential technology demonstration stepping stones to more capable systems needed in the future of both agencies. This article outlines the issues and potential options for the US Government to address these serious shortcomings.
