Launch Time: 3:30 AM EST

Launch Vehicle: Vulca n Centaur
🛰 Payload: GSSAP-7 &\; GSSAP-8
🎯 Mission Typ e: National Security / Space Domain Awareness

Mission Overvi ew &\; Payload Insight

USSF-87 will deploy GSSAP-7 and GSSAP-8\, the next pair o f satellites in the Geosynchronous Space Situational Awareness Program (GSSAP) operated by the United States Space Force.

GSSAP satellites operate in geo synchronous Earth orbit (GEO) and are designed to provide high-fidelity tracking and characterizati on of objects in this critical orbital regime. Unlike traditional wide-area surveillance satellites\, GSSAP spacecraft can maneuver near ot her satellites to collect detailed observations\, supporting attribution\, anomaly resolution\, and long-term space safety.

This mission also advances the operational deployment of United Launch Alliance&rsquo\;s Vul can Centaur for high-priority national security payloads u nder the NSSL program.
