ULA Vulcan Rocket Launches USSF-87 Mission, Addressing Anomaly

ULA's Vulcan rocket launched the USSF-87 mission from Cape Canaveral Space Force Station.

The primary payload included Geosynchronous Space Situational Awareness Program (GSSAP) satellites.

An 'observation' or anomaly occurred early in the flight with one of the four solid rocket motors.

The rocket flew in a VC4S configuration, utilizing four side-mounted Graphite Epoxy Motor (GEM) 63XL solid rocket boosters (SRBs).

The USSF-87 mission will aid in refining tactics and procedures for on-orbit maneuvers and enhance resilience in geosynchronous orbit.

Payload:: The mission's primary payload is the GSSAP system, enhancing the U.S. Space Command's awareness of activities in geostationary Earth orbit. The mission also includes additional research, development, and training systems mounted to Northrop Grumman’s ESPAStar platform.

Rocket Configuration:: The Vulcan rocket flew in a VC4S configuration, using four solid rocket boosters.

Anomaly:: ULA reported an 'observation' early in the flight related to one of the solid rocket motors, though the booster, upper stage, and spacecraft continued on a nominal trajectory. Data is being reviewed to understand the issue.

ULA successfully launched the USSF-87 mission, which is critical for U.S. space surveillance.

The Vulcan rocket experienced an early anomaly, which is under investigation.

The GSSAP satellites enhance space situational awareness and improve flight safety in geostationary orbit.

This mission supports the U.S. Space Force's ability to monitor and protect assets in space.
