About the Amazon Leo (LA-06) Mission
- Type: Communications
- Orbit: Low Earth Orbit
- Launch Cost: $153,000,000
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.
29 satellites are carried on this launch.
This mission supports Amazon Leo, a satellite internet constellation competing with Starlink to provide global broadband coverage. Amazon Leo aims to deploy thousands of satellites in low Earth orbit to deliver fast, affordable internet service to unserved and underserved communities around the world.
Launch Pad & Location
Space Launch Complex 41
Cape Canaveral SFS, FL, USA
The Space Launch Complex 41 launch pad has hosted 124 rocket launches, including 124 orbital launch attempts. The Cape Canaveral SFS, FL, USA launch site has been the location for 1114 total rocket launches.
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida.
United Launch Alliance Atlas V 551 Rocket
Atlas V is an expendable launch system in the Atlas rocket family. It was formerly operated by Lockheed Martin and is now operated by United Launch Alliance (ULA), a joint venture with Boeing. Each Atlas V rocket uses a Russian-built RD-180 engine burning kerosene and liquid oxygen to power its first stage and an American-built RL10 engine burning liquid hydrogen and liquid oxygen to power its Centaur upper stage. The RD-180 engines are provided by RD Amross, while Aerojet Rocketdyne provides both the RL10 engines and the strap-on boosters used in some configurations. The standard payload fairing sizes are 4 or 5 meters in diameter and of various lengths. Fairings sizes as large as 7.2 m in diameter and up to 32.3 m in length have been considered. The rocket is assembled in Decatur, Alabama and Harlingen, Texas.
