Included was COSMIC-2, a cluster of six satellites, with a mass of 277.8 kg each. The primary role of the COSMIC-2 satellite constellation is to provide radio occultation data with an average latency of 45 minutes. The six satellites were placed on an orbit with an inclination of 24 to 28.5 degrees with plans for them to move eventually to six separate orbital planes with 60 degree separation between them. The payload stack was integrated using an ESPA ring. Two ESPA Grande rings were used to mount the six COSMIC-2 satellites beneath the upper payload adapter hosting the DSX payload and avionics modules.
