Future of SpaceX Starlink and Starships

SpaceX has submitted requests to add 30,000 satellites for Starlink 3.0. They had 20 filings to the ITU (International Telecommunications for 1,500 satellites apiece in various low Earth orbits. SpaceX had originally filed for an initial Starlink network of 4425 satellites. Once the first 1000 satellites are up they will be able to start operation.
Starlink Constellations
Starlink 1.0 4,425 satellites around the end of 2021
Starlink 2.0 7,518 satellites around the end of 2023
Starlink 3.0 30,000 satellites around the end of 2027
In November 2018, SpaceX received US regulatory approval to deploy 7,518 broadband satellites, in addition to the 4,425 approved earlier. SpaceX’s initial 4,425 satellites had been requested in the 2016 regulatory filings to orbit at altitudes of 1,110-kilometer (690 mi) to 1,325-kilometer (823 mi). The new approval was for the addition of a very-low Earth orbit NGSO [non-geostationary satellite orbit] constellation, consisting of 7,518 satellites operating at altitudes from 335-kilometer (208 mi) to 346-kilometer (215 mi). In November, SpaceX altered the orbits of 1,600 from 1,150 km (710 mi) to only 550 km (340 mi) orbital altitude.
In April 2019, the FCC approved place nearly 12,000 satellites in three orbital shells: initially approximately 1,600 in a 550-kilometer (340 mi)-altitude shell, and subsequently placing ~2800 Ku- and Ka-band spectrum satellites at 1,150 km (710 mi) and ~7500 V-band satellites at 340 km (210 mi).
The next 30,000 satellites would operate in low Earth orbit at altitudes ranging from 328 kilometers to 580 kilometers.
Elon Musk would leverage the Tesla experience of scaling to the production of 500,000 electric cars to scale up satellite mass production.
SpaceX Launch Timing
SpaceX launched 60 Starlink 0.9 prototypes in a Falcon 9.
The 60 Starlink v0.9 satellites, launched May 2019, have the following characteristics:
Flat-panel design with multiple high-throughput antennas and a single solar arrayMa ...
