ESPA mounts to the standard NSSL (formerly EELV) interface bolt pattern (Atlas V, Falcon 9, Delta IV, OmegA, Vulcan, New Glenn) and is a drop-in component in the launch stack. Small …

The Moog ESPA is manufactured from a 7000-series aluminum ring forging. The original ESPA replicates the EELV standard interface, i.e., 62.01” (1575 mm) in diameter, with 120 evenly …

The initial ESPA ring was designed to support a 15,000-pound (6,800 kg) primary payload and up to six 400-pound (180 kg) secondary payloads. Each secondary spacecraft is mounted radially …

ESPA, the Evolved Secondary Payload Adapter, was developed for the Air Force to utilize excess launch capacity by mounting additional payloads below the primary spacecraft. This reduces …

AFRL first demonstrated the ESPA when a 2014 satellite named “ANGELS” hitched a ride on an ESPA, undocking after launch to carry out its science mission. The next level of complexity will …

Satellites are mounted externally to the ESPA ring with a variety of port options, and features can be added for internal mounting or mission specific structure modifications. ESPA mounts to the …

the ESPA ring, which was originally designed to hold up to 6 small satellites weighing 205 kg each, supports the LCROSS spacecraft subsystems on panels mounted to each adaptor …

The primary payload adapter cone is mounted to the top of ESPA. To eliminate primary payload mechanical interface concerns, the top of ESPA will replicate the Standard Interface Plane. …

Small payloads mount to ESPA ports featuring either a Ø15-inch bolt circle with 24 fasteners or a 4-point mount with pads at each corner of a 15-inch square; both of these interfaces have …
