Read More expand_more
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.
35-40 satellites will be carried on each Ariane 6 launch.

Core Stage Separation
MECO and core stage separation; the core stage re-enters over the ocean.
MES-1 (Vinci Ignition)
Vinci ignites for the first time to reach an initial parking orbit.
SECO-1
First cutoff of the Vinci engine; coast phase begins (APU supports propellant settling).
MES-2 (Vinci Reignition)
Vinci restarts after a long coast to circularize the orbit or change inclination.
SECO-2
Final cutoff after reaching the target orbit.
Payload Deployment
Satellites are released into their designated orbits.
MES-3 (De-orbit Burn)
Final short burn to ensure re-entry and safe splashdown in a remote Pacific area.
