Falcon 9 Starlink Group 17-28: Launch Succeeds June 21, 2026

Did the launch succeed?

Yes. SpaceX successfully launched Starlink Group 17-28 aboard a Falcon 9 Block 5 rocket on 21 June 2026 at 16:39:06 UTC from Space Launch Complex 4E at Vandenberg Space Force Base, California. The mission added another batch of Starlink broadband satellites to SpaceX's low-Earth-orbit constellation.

The Falcon 9 Block 5 is a two-stage, partially reusable orbital rocket built by SpaceX, and it remains the most-flown operational launch vehicle in the world. Starlink is SpaceX's satellite internet network, which has grown to more than 7,000 operational spacecraft since deployments began in 2019.

What was the payload?

The payload was a batch of Starlink v2 Mini satellites for the Group 17-28 mission. These spacecraft join the western-facing orbital shells that provide low-latency broadband coverage across the globe, including remote and underserved regions.

Key facts about the Starlink constellation:

• 7,000+ operational satellites currently in orbit
• Operating altitude around 550 km in low Earth orbit
• Each v2 Mini carries upgraded phased-array antennas and higher throughput than earlier versions
• Millions of active subscribers across more than 100 countries, according to SpaceX

Vandenberg launches like this one typically target higher-inclination orbits, filling the polar and near-polar shells that complement the equatorial coverage launched from Florida.

Where did it launch from?

The mission lifted off from Space Launch Complex 4E (SLC-4E) at Vandenberg Space Force Base on the central California coast. SLC-4E is SpaceX's primary West Coast Falcon 9 pad and supports frequent Starlink and rideshare missions requiring southward launch trajectories over the Pacific Ocean.

You can explore the pad location, orbital tracks, and other missions on our Vandenberg launch hub and SpaceX launch schedule.

How the mission unfolded

Following a nominal countdown, the Falcon 9's nine Merlin 1D engines ignited and the vehicle climbed south from the California coast. The first stage separated roughly two and a half minutes into flight and executed its landing burn, while the second stage continued to orbit to deploy the Starlink satellites.

SpaceX routinely recovers the first stage on an autonomous droneship stationed in the Pacific Ocean for Vandenberg missions. Booster reuse is central to the Falcon 9 economics, with many boosters now exceeding 20 flights each.

Why Starlink keeps launching

SpaceX maintains a high launch cadence to expand capacity and replace older satellites, which are designed to deorbit and burn up harmlessly at the end of their service life. The company has launched Starlink at a pace exceeding two missions per week in recent years, making it the dominant driver of global orbital launch traffic.

How to track the satellites live

The newly deployed Starlink spacecraft will spread out along their orbital plane over the following days, initially visible as a bright "train" of lights shortly after sunset or before sunrise. You can follow them in real time:
