DESCRIPTION:A SpaceX Falcon 9 Block 5 rocket will launch a batch of 26 Sta
 rlink v2 Mini Optimized satellites into low Earth orbit. This flight is in
 ternally known as Starlink Group 15-3 and the booster is designated as B10
 81.14 for this mission\, flying with a reused fairing.\n-\nStarlink v2 Min
 i Optimized satellites are built by SpaceX and have a reported launch mass
  of 575kg. The mass-produced spacecraft carry a communications payload usi
 ng the Ku and Ka frequency bands\, plus E-band for backhaul\, which will a
 llow Starlink to provide ~4x more capacity per satellite than earlier iter
 ations. They also employ optical inter-satellite links\, phased array beam
  forming and digital processing technologies. On the v2 sats the Krypton t
 hrusters are replaced with new and more powerful Argon Hall thrusters. The
  Optimized chassis features upgrades\, such as a new backhaul antenna with
  a SpaceX-designed and built dual-band chip and improved avionics\, propul
 sion and power systems. Starlink sats are able to track on-orbit debris an
 d capable of autonomous collision avoidance. All satellites will be equipp
 ed with anti-reflective coatings.\nThe updated Starlink network architectu
 re has 1584 satellites at 550km altitude and an inclination of 53 degrees\
 , 1584 satellites at 540km and an inclination of 53.2 degrees\, 720 satell
 ites at 570km and an inclination of 70 degrees\, and 520 satellites at 560
 km and an inclination of 97.6 degrees. The initial FCC application covered
  4408 Starlink satellites. Eventually SpaceX will launch and operate a fol
 low-on network of 7518 additional Starlink satellites transmitting in V-ba
 nd frequencies. In the final deployment stage an additional 30000 Starlink
  satellites might get orbited.\n-\nDelayed from May 1. Scrubbed on May 3.\
