DESCRIPTION:A United Launch Alliance Vulcan rocket\, designated V-012\, wi
 ll launch a batch of 40 operational satellites for Amazon's Kuiper constel
 lation. The mission is known as Vulcan Leo 1 by ULA and LV-01 by Amazon. T
 he Centaur stage will deploy the satellites in an initial orbit of 450km a
 ltitude\, the satellites will then use their electric propulsion systems t
 o settle into their assigned final orbits. The Kuiper constellation will e
 nable Internet service for customers between 56 degrees north and south la
 titude. Vulcan will fly in the VC6L vehicle configuration with a double-en
 gine Centaur CV-L upper stage\, six solid rocket boosters and a long fairi
 ng. CV-L\, is 1.94m shorter than the original Centaur V\, now renamed CV-H
 E (Centaur V High Energy). Unlike the CV-HE\, which uses a hydrolox-fueled
  reaction control system\, the CV-L will employ a hydrazine-fueled RCS.\n\

 Leo constellation (formerly known as Project Kuiper) are a significant upg
 rade from the two prototype satellites of the Kuiper Protoflight mission. 
 The ~572kg satellites are equipped with Hall-effect thruster technology fo
 r propulsion. They feature improved systems and sub-systems on board\, inc
 luding phased array antennas\, processors\, solar arrays\, propulsion syst
 ems\, and optical inter-satellite links. In addition\, the satellites are 
 coated in a dielectric mirror film unique to Amazon Leo that scatters refl
 ected 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 sate
 llite ground station facilities. In addition to connecting to ground stati
 ons\, 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 ope
 rating in 98 orbital planes in three orbital shells\, one each at 590km
 \, 610km and 630km orbital altitude. Kuiper satellites will fly in mid-inc
 lination orbits\, enabling Internet service for customers between 56 degre
 es 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 f
 ive phases of constellation development are planned.\n-\nDelayed from Sept
 ember\, December 2025\, Q1\, August\, September and October. Scrubbed on N
 ov. 13 and 14.\n\nWebcast: https://www.youtube.com/live/qM5A1ZO9oh8\nhttps
