A rocket launch at four in the morning has an almost cinematic quality. The gloom. The quiet before the fire. Then everyone within miles who wasn’t already watching was awakened by that wall of light and sound that rolled across the Florida coast. That is precisely what United Launch Alliance’s Vulcan Centaur accomplished on February 12, 2026, when it launched from Space Launch Complex-41 at Cape Canaveral at 4:22 a.m. EST with a mission that weighs more than just its payload.
The USSF-87 mission was the fourth flight of ULA’s Vulcan Centaur, a 202-foot-tall replacement for the dependable Atlas V. It carried two satellites for Northrop Grumman’s Geosynchronous Space Situational Awareness Program, or GSSAP for short. These satellites were intended to function at a height of approximately 22,236 miles above Earth in geostationary orbit. These spacecraft are referred to as “neighborhood watch” satellites by the Space Force. It sounds almost like something from a suburban homeowners association. In reality, though, it describes one of the most advanced surveillance systems ever put into orbit by humanity.

Prime real estate is geostationary orbit. At that height, a satellite’s orbital speed coincides with Earth’s rotation, giving the impression that it is constantly hovering over the same location. There are weather satellites. There are satellites for communications. There are assets for reconnaissance. The Space Force wants to keep an eye on the area because rival countries’ satellites are increasingly located there as well. “Better information about the position and activities of satellites within the increasingly crowded GEO drastically speeds USSF space operators’ ability to warn others if another object is anticipated to approach too closely,” officials said in a release related to the mission. Yes, it’s space traffic management, but it’s also more subtly strategic.
There was a moment in the launch itself. One of the rocket’s four solid rocket boosters began to flicker sparks shortly after liftoff, as seen by onlookers on the ground and cameras monitoring the flight. ULA promptly reassured the public after confirming the anomaly. The spacecraft, booster, and upper stage all maintained their nominal trajectory. The two GSSAP satellites were delivered to their assigned orbit six hours after launch. Ultimately, nothing was derailed by the glitch. However, it’s difficult to ignore the fact that a solid rocket booster problem has occurred on previous Vulcan missions. It is truly amazing that the rocket was successful in spite of the anomaly. It remains to be seen if such resilience develops into a pattern or if it conceals more fundamental engineering issues.

Prior to this mission, six GSSAP satellites had already been launched in pairs in July 2014, August 2016, and January 2022. Each pair increased the Space Force’s capacity to monitor events in GEO, not only for military objectives but also, according to officials, to promote flight safety for all spacefaring countries. This diplomatic framing is both strategically advantageous and technically correct. To prevent collisions, it is helpful to always know where every satellite is. It is also helpful for other things that are often left out of official statements.
A number of research and development payloads intended to enhance orbital precision maneuvering and bolster the resilience of US assets in GEO were also carried aboard USSF-87. Given the nature of national security missions, it is not surprising that there are still few details available about those. However, their presence implies that the U.S. Space Force is not merely observing. It’s quietly expanding its operational reach at altitudes most people never consider, testing new capabilities, and improving methods.
Here, the Vulcan Centaur itself merits some discussion. Even though this was only its fourth flight, it is already being utilized for critical national security missions. That speaks to both the Space Force’s timeline constraints and ULA’s confidence in the vehicle. Although the rocket’s lack of reusability places it at a philosophical disadvantage when compared to SpaceX’s Falcon 9, its performance features make it especially well-suited for heavy payloads traveling to high orbits. Commercial and government missions are part of ULA’s upcoming busy schedule. It is obvious that the company, a joint venture between Lockheed Martin and Boeing, is wagering on Vulcan to serve as the foundation for its next phase.
From the outside, it seems like the space domain is evolving more quickly than public discourse has kept up. Although the term “neighborhood watch” is used almost casually, it refers to a world in which countries are actually vying for awareness and positioning in orbital space using sensors, satellites, and data rather than flags and footprints as was the case during the Apollo era. One component of that image is the GSSAP constellation. Most likely, it won’t be the last.
Currently circling at a distance of 22,000 miles, the two new satellites are up there observing. Depending on where you are, that may or may not make you feel safer.
