Summary
Amazon Leo (KF-03) launched on a SpaceX Falcon 9 Block 5 from Space Launch Complex 40, Cape Canaveral SFS, FL, USA on October 14, 2025 at 01:58 UTC. The launch window ran from 00:08 to 02:22 UTC. It was SpaceX's 582nd launch, 133rd this year and humanity's 7,083rd orbital launch attempt. It was the 489th Falcon 9 Block 5 flight and the 128th this year. Booster B1091 flew for the 2nd time and landed at A Shortfall of Gravitas. The payload was bound for low Earth orbit (LEO). The tracked orbit of Kuiper-00101, one of 24 catalogued objects, from October 22, 2025, was 466 × 474 km inclined 51.9°. 24 objects from this launch are catalogued, all of them payloads.

About this launch
Third of a three launches contract for Amazon's Kuiper low Earth orbit satellite internet constellation, with 24 satellites on board. Amazon Leo, formerly known as Project Kuiper, is a mega constellation of satellites in Low Earth Orbit that will offer broadband internet access, this constellation will be managed by Kuiper Systems LLC, a subsidiary of Amazon. This constellation is planned to be composed of 3,276 satellites. The satellites are projected to be placed in 98 orbital planes in three orbital layers, one at 590 km, 610 km and 630 km altitude.
