Payload Manifest

The 40 payloads are mounted on top of the second rocket stage, and SpaceX shared a photograph of the interior of the fairing that shows the payloads arranged in a special configuration on the adapter with ESPA (Evolved Expendable Launch Vehicle Secondary Port Adapter) ring technology.


ESPA allows dozens of small spacecraft to be connected to the payload adapter to get the most out of a rocket launch in a single mission, as illustrated below. The Payload Host Companies also have the option of using custom ESPA satellite adapters.
