STARSHIP PAYLOAD GUIDE ACOUSTICS SHOCK During flight, the payload will be subjected to a range SpaceX is designing Starship to have benign shock of acoustic environments. Levels are highest during environments. Stage separation and payload fairing liftoff and transonic flight, due to acoustic and door opening will generate negligible shock aerodynamic excitations. The maximum expected environments at the payload interface. Consequently, payload acoustic environments are shown in Table 1 the maximum shock environment is typically due to the and Figure 6 in one-third octave bands.

OASPL (dB) 137.7 Then the integrated payload stack is transferred to the Table 1: Payload acoustic environment (1/3 octave) launch pad and lifted onto the Starship vehicle, while maintaining the same vertical orientation throughout the entire process. Conditioned air is delivered into the fairing during encapsulated ground processing while in the processing facility and on the launch pad. PAYLOAD SEPARATION SpaceX provides in-flight commanding and monitoring of the payload separation system(s). Starship can perform 3-axis attitude controlled or spin-stabilized spacecraft separation. Note that certain spacecraft separation maneuvers may reduce available payload volume. Collision avoidance maneuvers will be performed as required.
