About the mission
USSF-87 will launch two identical Geosynchronous Space Situational Awareness Program (GSSAP) satellites GSSAP-7 and GSSAP-8 directly to a near-geosynchronous orbit approximately 36,000 km above the equator. Data from the GSSAP will uniquely contribute to timely and accurate orbital predictions, further enabling space flight safety including satellite collision avoidance.
