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
Opening the spaceways
Identifies spaceplane technical concepts proposed by both large and small companies. Highlights that the size and complexity of spaceplanes can be bounded by two well-defined concepts: the Lockheed
Military Spaceplane Flight Demonstration Concepts
*† ‡ This paper re views flight demonstration concepts prepared by and for the Air Force Research Laboratory’s Air Vehicle’s Directorate in support of the Space and Missile Systems Center and the
Electric propulsion for orbit transfer - A case study
TLDR
Use of the EOTV in lieu of a chemical upper stage potentially reduces the Space Shuttle cargo element mass and the transport-to-orbit life-cycle cost by 4 to 61%, or up to $21 million per flight, while still meeting a 90-day flight time requirement.
Military applications of reusable launch vehicles (RLVs)
With the development and operational fielding of fully reusable launch vehicles (RLVs) becoming imminent, coupled with the ‘‘end of the Cold War’’ and fractionalization of the former ‘‘bi‐polar’’
Augmenting the Space Shuttle with a space station and tug
Nonlinear optimization techniques are used to quantify the impact of adding a space fueling station and reusable tug to the Space Transportation System (STS). The Shuttle deploys all space traffic to
