* launch Vehicle: SpaceX Falcon 9 rocket.
* Launch Location: space Launch Complex 40 at Cape Canaveral Space Force Station,Florida.
* Deployment: Satellite will deploy from the rocket’s upper stage roughly 1.5 hours after liftoff.

Key Players:

* U.S. Space Force: Overseeing the mission.
* Space Systems Command (SSC): Manages the National Security Space Launch (NSSL) program.
* Combat Forces Command (CFC): Responsible for pre-launch satellite processing.
* Lockheed Martin: Satellite manufacturer.
* spacex: Launch provider.
* United Launch Alliance (ULA): Originally scheduled for the launch, but missions were swapped.

Rocket & Recovery:

* Booster: Falcon 9 first stage booster B1096 (5th flight).
* Landing: Planned landing on the drone ship “A Shortfall of Gravitas” in the Atlantic Ocean approximately 8.5 minutes after liftoff. This would be the 141st landing on that vessel and SpaceX’s 564th booster landing overall.

Weather:

* A 95% chance of favorable weather is forecast for the launch window on Tuesday.A strong cold front is expected to clear before launch.

Mission Swaps:

* This marks the third time the Space Force has shifted a GPS 3 satellite launch from a ULA Vulcan rocket to a SpaceX Falcon 9.
* The swaps were part of the NSSL Phase 2 contract between ULA and SpaceX.
* Current Assignments:

* GPS 3-9 (SV09) – SpaceX Falcon 9
* GPS 3-8 (SV10) – ULA Vulcan
* GPS 3F-1 (SV11) – ULA Vulcan
* GPS 3F-2 (SV12) – ULA Vulcan
* GPS 3F-3 (SV13) – ULA Vulcan

Additional Information:

* Spaceflight now will provide live coverage of the launch, starting an hour before liftoff.
* This will be SpaceX’s second national security flight of the year.

Why did SpaceX postpone the GPS‑3‑9 launch to Tuesday night?

SpaceX Delays GPS‑3‑9 Satellite Launch to Tuesday Night Amid Weather Concerns

SpaceX has announced a delay in the launch of the GPS III-9 satellite, pushing the liftoff to Tuesday night, January 27th, 2026. The postponement is due to unfavorable weather conditions predicted over Cape Canaveral Space Force Station in Florida. this marks the latest in a series of adjustments for the mission, originally slated for launch in late 2023.

Understanding the GPS III Program & Satellite Importance

The GPS III program represents a notable upgrade to the Global positioning System, operated by the United States Space Force. These next-generation satellites offer enhanced accuracy, improved anti-jamming capabilities, and a new civilian signal (L1C) that benefits international users.

* Increased Accuracy: GPS III satellites deliver signals three times more accurate than their predecessors.

* Enhanced security: Advanced features protect against signal interference and jamming attempts.

* Interoperability: the L1C signal ensures compatibility with other global navigation satellite systems (GNSS) like Galileo,GLONASS,and BeiDou.

The GPS III-9 satellite is the final satellite in the Block I series of the program. Its triumphant deployment is crucial for maintaining and improving the reliability of GPS services used worldwide. these services underpin critical infrastructure, including aviation, banking, emergency response systems, and everyday navigation apps.

Weather Conditions Prompting the Delay

Current forecasts indicate a high probability of adverse weather conditions during the initial launch window. Specifically, concerns center around:

* Strong Upper-Level Winds: These winds can pose a risk to the Falcon 9 rocket during ascent.

* Cloud Cover: Thick cloud cover can create unfavorable conditions for tracking the rocket and ensuring a safe launch.

* Potential for Lightning: The presence of thunderstorms near the launch pad necessitates a delay for safety reasons.

SpaceX prioritizes safety and adheres to strict launch criteria. the decision to postpone reflects a commitment to minimizing risks and ensuring mission success. The 45th Weather Squadron at Patrick Space Force Base provides detailed weather forecasts specifically for launch operations.

launch Details & What to Expect

The launch is currently scheduled for Tuesday night, january 27th, 2026, with a launch window opening at 7:53 PM EST. The Falcon 9 rocket will lift off from Space Launch complex 40 (SLC-40) at Cape Canaveral Space Force Station.

Hear’s a breakdown of the expected launch profile:

1. First Stage Separation: Approximately 2 minutes and 30 seconds after liftoff, the first stage of the Falcon 9 will separate and return to earth for landing.
2. Second Stage Ignition: The second stage will ignite to continue propelling the GPS III-9 satellite towards its intended orbit.
3. Satellite Deployment: approximately 1 hour and 10 minutes after liftoff, the GPS III-9 satellite will be deployed into medium Earth orbit (MEO).
4. Orbital Testing: Following deployment, the satellite will undergo a series of tests to verify its functionality and ensure it’s operating as expected.

SpaceX’s Falcon 9: A Reliable Launch Vehicle

The Falcon 9 is a partially reusable two-stage-to-orbit medium-lift launch vehicle. It’s become SpaceX’s primary launch system, known for its reliability and cost-effectiveness.

* Reusable First Stage: The Falcon 9’s first stage is designed to land back on Earth, either on a drone ship at sea or back at the launch site, enabling reuse and reducing launch costs.

* Proven Track Record: The Falcon 9 has flown over 150 successful missions as of early 2026, carrying satellites, cargo, and astronauts to orbit.

* Continuous Improvements: SpaceX consistently implements upgrades and improvements to the Falcon 9, enhancing its performance and reliability.

Impact of Delays on GPS Services

While delays are common in space launches, they can have ripple effects. Though, the GPS constellation is robust, with multiple satellites in orbit.The delay of GPS III-9 is not expected to cause any immediate disruption to GPS services. The existing satellites continue to provide full operational capability. the addition of GPS III-9 will further strengthen the constellation and enhance overall system performance.
