Falcon 9 Block 5, flown by SpaceX
This was SpaceX's 86th launch of 2026, and its 705th in all.
Counting every operator, it was the 169th orbital launch attempt anywhere in 2026, and the 45th from Space Launch Complex 4E.

Tranche 1 Transport Layer E is one of six missions by the United States Space Force Space Development Agency (SDA) for the Proliferated Warfighter Space Architecture (PWSA) Tranche 1 Transport Layer constellation, which will provide assured, resilient, low-latency military data and connectivity worldwide to the full range of warfighter platforms from Low Earth Orbit satellites. The constellation will be interconnected with Optical Inter-Satellite Links (OISLs) which have significantly increased performance over existing radio frequency crosslinks. It is expected to operate over Ka band, have stereo coverage and be dynamically networked for simpler hand-offs, greater bandwidth and fault tolerance. This launch carries 21 satellites manufactured by York Space Systems.
Falcon 9 is a two-stage rocket designed and manufactured by SpaceX for the reliable and safe transport of satellites and the Dragon spacecraft into orbit. The Block 5 variant is the fifth major interval aimed at improving upon the ability for rapid reusability.
627 flights, 626 of them successful. 612 boosters brought back from 617 attempts.
First stage Second stage
Simulated from the published flight plan. The climb flattens as the rocket pitches over to build sideways speed, which is why a launch stays visible so far from the pad. A dashed line is a stage that separates and flies back down, either to the pad or to a ship waiting downrange.
Going to watch it in person? Flyby's Pathfinder points your camera at the pad, so you are not stood there guessing which one it goes up from. It puts this same climb on a globe you can turn, too.
Space Exploration Technologies Corp., known as SpaceX, is an American aerospace manufacturer and space transport services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars. SpaceX operates from many pads, on the East Coast of the US they operate from SLC-40 at Cape Canaveral Space Force Station and historic LC-39A at Kennedy Space Center. They also operate from SLC-4E at Vandenberg Space Force Base, California, usually for polar launches. Another launch site is being developed at Boca Chica, Texas.
724 launches so far, 709 of them successful. The last 209 in a row went to plan.
It went up from Space Launch Complex 4E at Vandenberg SFB, CA, USA.
This one is done, but there is another along shortly. Flyby works out whether it climbs into your sky, and wakes you in time to get outside.
