Starlink Group 10-43 Launch Recap: Falcon 9 Success June 4, 2026

What happened?

SpaceX successfully launched the Starlink Group 10-43 mission on a Falcon 9 Block 5 rocket at 10:26:30 UTC on 4 June 2026 from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station, Florida. The mission added another batch of Starlink internet satellites to low Earth orbit, and SpaceX confirmed a successful outcome.

The Falcon 9 is a two-stage, partially reusable orbital rocket built and operated by SpaceX, and the Block 5 is its final, most-flown variant designed for rapid booster reuse. Starlink is SpaceX's satellite broadband constellation, which delivers low-latency internet to customers worldwide.

Did the launch succeed?

Yes. According to SpaceX, the launch of Starlink Group 10-43 was a success. The first stage separated, the second stage completed its burn to low Earth orbit, and the batch of Starlink v2 Mini satellites was deployed as planned. Falcon 9 has now flown more than 400 times, with the overwhelming majority being Starlink deployment flights.

What was the payload?

The payload was a batch of Starlink satellites bound for low Earth orbit at roughly 550 km altitude. Each Falcon 9 Starlink mission typically carries between 20 and 28 satellites depending on the variant and orbital shell targeted. These spacecraft join the operational Starlink network, which is the largest satellite constellation ever built, with well over 7,000 active satellites in orbit.

Key mission facts

How does Starlink Group 10 fit in?

Starlink satellites are organized into groups and orbital shells that together form a global mesh. The Group 10 shell is one of several inclination bands SpaceX uses to build worldwide coverage, and each new launch tightens the grid and increases network capacity. The constellation uses inter-satellite laser links to route traffic in space, reducing reliance on ground stations.

These second-generation v2 Mini satellites are heavier and more capable than the original design, offering roughly four times the usable bandwidth per spacecraft, according to SpaceX. Once deployed, each satellite raises itself to its operational altitude using onboard ion thrusters before entering service.

What about the booster?

SpaceX recovers Falcon 9 first stages for reuse, typically landing them on autonomous droneships stationed in the Atlantic Ocean for east-coast Starlink flights. Booster reuse is the core of SpaceX's cost model, with individual boosters having flown well over 20 times each. Reflight and recovery of the first stage are standard on Starlink missions, allowing SpaceX to maintain its high launch cadence.
