On April 29, 2026, SpaceX successfully used its Falcon Heavy rocket to deliver the 6-ton ViaSat-3 F3 communications satellite into its intended orbit. This marked the Falcon Heavy’s first launch since October 2024 and the final mission in the ViaSat-3 constellation of three terabit-class communications satellites.

A Launch After Setbacks

According to Spaceflight Now, the mission did not proceed without challenges. SpaceX had originally scheduled the launch for Monday but was forced to delay due to unfavorable weather conditions. After a two-day wait, the launch window finally opened on April 29, and the Falcon Heavy rocket lifted off smoothly from Launch Complex 39A at Kennedy Space Center.

Space.com noted that the 18-month gap represents the longest hiatus in Falcon Heavy’s launch history. During this period, SpaceX focused primarily on Starship development and the high-frequency Falcon 9 launch cadence. This return demonstrates the Falcon Heavy’s irreplaceable role in heavy-payload missions.

The Significance of ViaSat-3 F3

ViaSat-3 F3 is the last of three satellites in the ViaSat-3 constellation. According to SpaceNews, the satellite employs terabit-class communications technology, capable of delivering over 1 Tbps of total data throughput across its coverage area — making it one of the highest-capacity commercial communications satellites in the world.

The three ViaSat-3 satellites collectively cover the Americas, Europe/Middle East/Africa, and the Asia-Pacific region, forming a global high-speed broadband network. The F3 satellite specifically serves the Asia-Pacific region and will significantly improve internet access capabilities, particularly in remote and underserved areas.

Launch Sequence Recap

During the launch, the Falcon Heavy’s two side boosters successfully returned to the landing zones near the launch site approximately 8 minutes after liftoff, completing another impressive demonstration of reusable rocket technology. The center core stage performed its planned landing on a drone ship at sea, following SpaceX’s standard recovery procedure.

Looking Ahead

This launch reaffirms SpaceX’s continued leadership in heavy-lift launch vehicles. As the Starship program progresses, the Falcon Heavy may gradually yield to the larger launch system, but for now it remains the workhorse rocket for NASA deep-space missions and commercial heavy payloads.
