Northrop Grumman’s ESPAStar Platform provides a modular, cost-effective, and highly capable infrastructure resource for hosting technology development and operational payloads. The ESPAStar Platform uses a customized EELV Secondary Payload Adapter (ESPA) ring as part of its structure and is capable of being launched aboard any launch vehicle that meets the Evolved Expendable Launch Vehicle (EELV) standard interface specification, and the Falcon 9. The ESPAStar Platform's 6 payload ports are capable of accommodating any combination of up to 6 hosted and 12 separable (fly-away) payloads (maximum 1 hosted or 2 separables per port). The payload interface at each port has been standardized, allowing for hosted and separable Payload interchangeability, late Payload integration, and manifest changes. The ESPAStar Platform leverages the available mass margin from any EELV launch to provide an affordable path to space for payloads. The Platform is optimized for GEO missions, but is adaptable for LEO and MEO missions.
