ESPA (secondary payload adapter) will be implemented on the new generation of expendable launch vehicles, the evolved expendable launch vehicle-medium (EELV-M) boosters. ESPA will provide a cost-effective means for launching up to six small satellites, plus a large primary payload, on a single booster, while minimizing added impacts on the primary payload. In fact, ESPA can improve the dynamic environment seen by the primary payload through the use of whole-spacecraft, passive isolation systems. Vibration or shock isolation systems will be available for primary payloads; shock isolation will be offered for all secondary spacecraft. With whole-spacecraft isolation for all payloads, the addition of secondary payloads to the launch stack is expected to be transparent to the primary payload dynamic environment. ESPA is expected to reduce the launch dynamic environment for all payloads while shrinking the cost of launching a small satellite to less than 5% of the cost of a dedicated launch vehicle.
