ViaSat-3 F2 next operational steps include reflector deployment.

PlanCapabilityValue 4.0Mar 12, 2026RT by @GewoonLukas_: Our ViaSat-3 F2 satellite has reached its slot in geostationary orbit! 🛰️ Next steps include reflector deployment, In Orbit Testing followed by handover & terrestrial network integration in readiness for expected service entry across the Americas by May. pic.

Viasat and Boeing will begin deployment of Viasat-3 F2’s large antenna reflector now that the satellite is in GEO.

PlanCapabilityValue 4.0Mar 10, 2026ViaSat-3 F2 has arrived in GEO following its Atlas V launch! Now that the satellite is in GEO, Viasat & Boeing will begin the deployment of its huge antenna reflector. If this goes well, Viasat will move forward with the launch of ViaSat-3 F3 on Falcon Heavy in the coming months.

ViaSat-3 F2 required two years of additional work to diagnose the ViaSat-3 Americas (F1) antenna reflector anomaly and implement a fix.

CapabilityPlanValue 3.8Mar 10, 2026During the deployment of the ViaSat-3 Americas (F1) antenna reflector, an anomaly occured that means that the satellite can only operate at ~10% of its designed 1 Tbps capacity. This led to 2 years of additional work on ViaSat-3 F2 to diagnose the issue and implement a fix.

Viasat intends to proceed with the launch of ViaSat-3 F3 on a SpaceX Falcon Heavy in the coming months contingent on successful deployment of Viasat-3 F2’s reflector.

The circular radar antenna reflector of NISAR measures 12 meters in diameter and is the largest of its kind ever deployed in space.

CapabilityGeneralValue 4.5Oct 16, 2025RT by @GewoonLukas_: Full bloom on the most powerful radar satellite ever built—seen here with centimeter-level clarity. Vantor collected this image of the NISAR synthetic aperture radar (SAR) satellite after it deployed its giant circular radar antenna reflector in August. Developed jointly by @NASA and @isro, this reflector measures 12 meters in diameter and is the largest of its kind ever deployed in space. NISAR released first images late last month. For high-value assets in space, decision makers don't have days to wait for answers to critical questions. They need fast answers. Our WorldView Space non-Earth imaging capability is built for exactly this kind of mission. Here you can see the actual structural state—whether the mesh is properly tensioned, if the deployment geometry matches specifications, and how the spacecraft is oriented relative to its imaging targets. With this image, we also collected spacecraft orientation, velocity data, and deployment confirmation that telemetry alone can't verify. This is the kind of trusted intelligence that delivers total clarity to help you understand what's happening in Earth's orbit.
