Falcon 9 Starlink Group 10-31: Launch Success (21 May 2026)

What happened?

SpaceX successfully launched the Starlink Group 10-31 mission on a Falcon 9 Block 5 rocket at 10:04:20 UTC on 21 May 2026 from Space Launch Complex 40 (SLC-40) at Cape Canaveral Space Force Station, Florida. The mission delivered a new batch of Starlink internet satellites to low Earth orbit, and SpaceX confirmed the launch was a success.

Starlink is SpaceX's satellite broadband constellation, designed to provide low-latency internet coverage across most of the planet. Group 10-31 is one of many operational batches feeding the network, which now numbers more than 7,000 active satellites in orbit — the largest satellite constellation ever built.

When did the launch happen?

Liftoff occurred at 10:04:20 UTC on 21 May 2026, corresponding to 6:04 a.m. EDT local time at the Cape. Falcon 9 launches to the Starlink shells from Florida typically fly on southeast or northeast trajectories to reach the roughly 53-degree inclination orbital planes used by the Group 10 series.

What is the Falcon 9 Block 5?

The Falcon 9 Block 5 is a two-stage, partially reusable orbital rocket standing about 70 meters tall and capable of lifting roughly 22,800 kg to low Earth orbit in expendable configuration. It is the workhorse of SpaceX's fleet and the most-flown operational rocket in the world, with reusable first-stage boosters that return to land on either a droneship or a ground pad.

The first stage on a typical Starlink mission separates a few minutes after liftoff and executes a boostback and landing burn before touching down on an Atlantic droneship stationed downrange. Booster reuse is central to the economics that let SpaceX fly Starlink deployments at high cadence, with individual boosters having flown well beyond 20 missions each.

What was the payload?

The payload was a stack of Starlink v2 Mini satellites bound for the Group 10 shell of the constellation. These spacecraft carry phased-array antennas and laser inter-satellite links, allowing data to be routed between satellites in orbit without ground relays. After deployment, each satellite uses onboard ion thrusters to raise itself from the initial insertion orbit to its operational altitude of roughly 550 km.

How to watch the launch replay

SpaceX streams its Falcon 9 launches on its official channels, with the webcast beginning a few minutes before liftoff and running through booster landing and satellite deployment. You can relive the mission and follow the deployed satellites' orbital paths on the Cosmik live 3D satellite map, and browse the full rocket launch schedule for what flies next. Dedicated coverage of the constellation is available on the Starlink satellites hub.

Where can I track the Starlink satellites now?

Once deployed, the freshly launched batch is often visible as a bright "train" of lights crossing the night sky before the satellites disperse and climb to their operational altitude. Track that phenomenon on the Starlink train tracker, and see every object in orbit in real time on the Cosmik live map.

Why does this launch matter?

Each Starlink batch expands global broadband capacity and reduces network latency by filling out orbital planes. SpaceX has been launching Starlink missions at a pace of multiple flights per month, making the constellation the fastest-growing satellite network in history. Missions like Group 10-31 also demonstrate the sustained reliability and rapid reflight cadence of the Falcon 9 Block 5 fleet.
