DESCRIPTION:A United Launch Alliance Atlas V rocket\, designated AV-105\, 
 will launch the second batch of 27 operational satellites for Amazon's Kui
 per constellation. The mission is known as Kuiper 2 by ULA and KA-02 by Am
 azon. Total payload mass will be 15422kg. Atlas will deploy the satellites
  in an initial orbit of 450km altitude\, the satellites will then use thei
 r electric propulsion systems to settle into their assigned final orbits. 
 The Kuiper constellation will enable Internet service for customers betwee
 n 56 degrees north and south latitude. Atlas will fly in the 551 vehicle c
 onfiguration with a five-meter medium length fairing\, five GEM-63 solid r
 ocket boosters and a single-engine Centaur upper stage.\n\nMission profile
  video: https://youtu.be/ZATwTLIbQu8\n-\nOperational satellites of the Kui
 per constellation are a significant upgrade from the two prototype satelli
 tes of the Protoflight mission. The ~572kg satellites are equipped with Ha
 ll-effect thruster technology for propulsion. They feature improved system
 s and sub-systems on board\, including phased array antennas\, processors\
 , solar arrays\, propulsion systems\, and optical inter-satellite links. I
 n addition\, the satellites are coated in a dielectric mirror film unique 
 to Kuiper that scatters reflected sunlight to help make them less visible 
 to ground-based astronomers. Kuiper is planned to work in concert with Ama
 zon's network of 12 satellite ground station facilities. In addition to co
 nnecting to ground stations\, satellites will interconnect via optical inf
 rared laser connections. Amazon refers to this technology as OISL (optical
  inter-satellite link).\nThe Kuiper constellation is planned to consist of
  3236 satellites operating in 98 orbital planes in three orbital shells
 \, one each at 590km\, 610km and 630km orbital altitude. Kuiper satellites
  will fly in mid-inclination orbits\, enabling Internet service for custom
 ers between 56 degrees north and south latitude. Phase 1 of deployment wil
 l be 578 satellites at 630km altitude and an orbital inclination of 51.9 d
 egrees. A total of five phases of constellation development are planned.\n
