SUMMARY:(NET) Ariane 64 B2 • Amazon Leo
DTSTART;VALUE=DATE:20261020
DTEND;VALUE=DATE:20261021
UID:242557034710
DESCRIPTION:Arianespace will launch an Ariane 6 rocket\, on a flight desig
 nated VA271\, to put a batch of 36 operational satellites for the Amazon L
 eo constellation into orbit. The mission is known as LE-03 by Amazon. Aria
 ne 6 will fly in the Ariane 64 Block 2 configuration\, using four P160C ro
 cket boosters and a long fairing.\n-\nOperational satellites of the Amazon
  Leo constellation (formerly known as Project Kuiper) are a significant up
 grade from the two prototype satellites of the Kuiper Protoflight mission.
  The ~572kg satellites are equipped with Hall-effect thruster technology f
 or propulsion. They feature improved systems and sub-systems on board\, in
 cluding phased array antennas\, processors\, solar arrays\, propulsion sys
 tems\, and optical inter-satellite links. In addition\, the satellites are
  coated in a dielectric mirror film unique to Amazon Leo that scatters ref
 lected sunlight to help make them less visible to ground-based astronomers
 . Amazon Leo is planned to work in concert with Amazon's network of 12 sat
 ellite ground station facilities. In addition to connecting to ground stat
 ions\, satellites will interconnect via optical infrared laser connections
 . Amazon refers to this technology as OISL (optical inter-satellite link).
 \nThe Amazon Leo constellation is planned to consist of 3236 satellites op
 erating in 98 orbital planes in three orbital shells\, one each at 590k
 m\, 610km and 630km orbital altitude. Kuiper satellites will fly in mid-in
 clination orbits\, enabling Internet service for customers between 56 degr
 ees north and south latitude. Phase 1 of deployment will be 578 satellites
  at 630km altitude and an orbital inclination of 51.9 degrees. A total of 
 five phases of constellation development are planned.\n-\nDelayed from Oct
 . 7.\n\nWebcast:\nhttps://www.arianespace.com/road-to-space/
