ULA Vulcan Rocket Launches USSF-87 Mission with Surveillance Satellite
On February 12, 2026, United Launch Alliance (ULA) successfully launched its Vulcan rocket from Cape Canaveral Space Force Station as part of the USSF-87 mission for the U.S. Space Force. The mission included the deployment of a geosynchron...
Key Insights
- ULA launched the USSF-87 mission carrying multiple satellites for the U.S. Space Force.
- The primary payload was the Geosynchronous Space Situational Awareness Program (GSSAP) system, designed for space surveillance in geostationary orbit.
- A performance anomaly was observed in one of the solid rocket boosters shortly after liftoff.
- The Vulcan rocket is flying in a VC4S configuration, with four side-mounted solid rocket boosters.
- The mission duration was approximately 10 hours, the longest for a ULA mission to date.
In-Depth Analysis
The ULA Vulcan rocket, designated V-005, lifted off from Space Launch Complex 41 at Cape Canaveral Space Force Station at 4:22 a.m. EST. The rocket is configured with four side-mounted Graphite Epoxy Motor (GEM) 63XL solid rocket boosters and a standard payload fairing.
Approximately 20 seconds after liftoff, a visible performance anomaly occurred in one of the solid rocket boosters, with a jet of flame appearing from the nozzle. Despite this issue, the Vulcan booster and Centaur upper stage performed as expected, delivering the spacecraft directly to geosynchronous orbit.
The primary payload, the GSSAP system, is designed to monitor activities in geostationary orbit, which is critical for military and civilian communications satellites. The mission also included additional research, development, and training systems mounted on Northrop Grumman’s ESPAStar platform, enhancing on-orbit maneuver capabilities.
ULA aims to increase its launch cadence in 2026, with plans for multiple Atlas 5 and Vulcan flights. The investigation into the booster anomaly may impact this schedule.
FAQ
What was the anomaly observed during the launch?
A performance anomaly was observed in one of the solid rocket boosters, with a jet of flame appearing from the nozzle shortly after liftoff.
What is the GSSAP system?
The Geosynchronous Space Situational Awareness Program (GSSAP) is a dedicated Space Surveillance Network sensor designed to monitor activities in geostationary Earth orbit.
Takeaways
- The successful launch of the USSF-87 mission underscores the importance of continuous monitoring and surveillance in space. Despite a booster anomaly, the mission highlights the robustness of the Vulcan rocket and its capability to deliver critical payloads to complex orbits. Key actions to consider include staying informed about the investigation into the booster issue and understanding the implications for future space missions.
