SpaceX Starlink Progress Report

SpaceX Starlink spacecraft design continues to evolve according to a 13 March letter to the FCC, responding to questions on the Constellation architecture. The initial fleet of 75 Starlink spacecraft will include iron components including hall thrusters and reaction wheels which could survive reentry.

According to the attached letter:

  • The new spacecraft design is 100% consumable during atmospheric reentry.
  • Spacecraft will initially be launched to ~350km for orbital checkout prior to rising to its operational altitude.
  • Failure to check out the spacecraft will fall back to earth in weeks or months depending on how active the sun is. An active sun expands the atmosphere increasing drag.
