Technology applications to improve launch vehicle responsiveness

The Advanced Launch System (ALS) program is described which is primarily designed to investigate technologies for enhancing the responsiveness of launch vehicles. The ALS objectives for the second phase are highlighted including (1) the integration of payload in no more than 30 days; (2) the capacity to launch seven payloads in five days; and (3) the ability to substitute a payload in no more than five days. The use of integrated health monitoring and built-in testing is central to the program, and other mature technologies include automated manufacturing and launch, adaptive guidance, and a booster-recovery module. The operations concept and facilities are based on a standardized mission approach that can accommodate a family of vehicles. In conjunction with a support infrastructure based on technician transparency and commonality, the ALS is expected to provide an efficient and routine mechanism for space transportation and defense.
