New Approaches in U.S. Space Launch System’s Technology Development based on SUSTAIN Programm

The major purpose of this paper is to consider the strategy and long term approaches in th American U.S. Space Launch Systems (SLSs)’s technology development. Recently, new approaches has been interested by U.S.. The major roots of these approaches can be searched in the Small Unit Space Transportation and Insertion (SUSTAIN) program that is suggested by U.S. marine corps. The main objective of SUSTAIN is to convey facilities and equipmqnt to the any point of the earth in the minimum time and cost. Hence, the importance of this program leaded to develop the future SLSs’s technology in SUSTAIN orientation. Then, in this paper, the SUSTAIN’s needs is considered and also presented the new approaches in technology development of SLSs to meet the programm’s requirements.
