Firefly Alpha Launches ConnectedCosmos 1 on Sept 30, 2026

What is the ConnectedCosmos Launch 1 mission?

Firefly Aerospace's Alpha Block 2 rocket is scheduled to launch the ConnectedCosmos Launch 1 mission no earlier than September 30, 2026, at 00:00 UTC from Space Launch Complex 2W at Vandenberg Space Force Base, California. Alpha is a two-stage, all-carbon-composite small-satellite launch vehicle designed to place payloads of roughly 1,000 kg to low Earth orbit and about 630 kg to a 500 km sun-synchronous orbit.

The mission is one of Firefly's dedicated smallsat flights out of the U.S. West Coast, which offers efficient access to high-inclination and polar orbits favored by Earth-observation and communications payloads. The launch status is currently listed as TBD, meaning the date and time may shift as vehicle processing and range availability are finalized.

When is the launch?

The current target liftoff is September 30, 2026, 00:00 UTC. Because the mission is in a to-be-determined state, the precise time is subject to change. For the latest confirmed timing, check the live countdown on the Cosmik rocket launch schedule.

What is the Firefly Alpha rocket?

Firefly Alpha is a small-lift orbital launch vehicle built by Texas-based Firefly Aerospace. It stands roughly 29 meters tall and uses four Reaver engines on the first stage and a single Lightning engine on the second stage, all burning RP-1 kerosene and liquid oxygen. The Block 2 upgrade increases performance over the original Alpha, targeting improved payload capacity for dedicated and rideshare smallsat customers.

Where is it launching from?

The mission lifts off from Space Launch Complex 2W at Vandenberg Space Force Base on the California coast. Vandenberg's location allows rockets to fly south over the Pacific Ocean into polar and sun-synchronous orbits without overflying populated areas.

How to watch the launch live

Firefly Aerospace typically streams its Alpha launches via a live webcast beginning shortly before liftoff. Once the launch is confirmed, you can follow the countdown and the rocket's trajectory in 3D on Cosmik's live solar system and satellite map. After deployment, the payload will appear among the thousands of tracked objects in orbit.

• Confirm the exact liftoff time via the launch schedule and provider webcast.
• Watch the ascent and stage separation in real time.
• Track the deployed satellite after it separates from the second stage.

What is the payload?

The mission is designated ConnectedCosmos Launch 1, the first in a planned campaign. Firefly's Alpha vehicle is optimized for dedicated smallsat and constellation deployment, giving operators precise control over orbit selection and timing versus sharing a larger rideshare. Additional payload specifics will be confirmed closer to launch. Follow updates on the latest launch news page.

Why does this mission matter?

Dedicated small launchers like Alpha fill a growing market gap: they let single operators reach a custom orbit on their own schedule rather than waiting for a large rideshare manifest. As commercial constellations expand into the hundreds and thousands of satellites, responsive launch capability from West Coast pads becomes increasingly valuable. You can see how crowded low Earth orbit already is using the satellite tracking guide.

Launch background and sources

Firefly Aerospace has been developing and flying the Alpha vehicle from Vandenberg to build a cadence of dedicated smallsat missions. Launch data for this preview is sourced from The Space Devs Launch Library. Background on the vehicle and operator is available from Wikipedia's Firefly Alpha article, Firefly Aerospace, and Vandenberg Space Force Base.
