ESPAStar-D Satellite 3D model

Northrop Grumman's ESPAStar-D satellite bus. The ESPAStar family (comprising ESPAStar-D for small and ESPAStar-HP for large payloads) is built around the industry-standard EELV Secondary Payload Adapter (ESPA) ring as its primary structure, reducing development and integration costs for both the end customer, the launch provider, and other rideshare clients through common interfaces. For ESPAStar-D, the baseline 6-15-24 ESPA ring configuration is used by default, providing 6 radial attachment points for either fixed or deployable payloads with 15 inch diameter interfaces. The center volume is occupied by propulsion and guidance hardware, and the stowed 4-panel solar array. As on all ESPAs, the top of the ring remains available for mounting either a primary payload or additional rideshare adapters

All materials and textures are packed into the .blend file. Unapplied modifiers and instancing have been used to reduce file size and enable easy editing.
