Update on SpaceX Mega Constellation

  • Cameron

    Sounds good. Hopefully the system scales up well…

  • Michael Halpern

    It should, as I understand it, TinTin A & B are basically the same as the final sats but with less processing capacity as they are just testing the phase arrays and laser links. Communication across hundreds of sats so long as the laser links are good is just routing like terrestrial systems

  • Cameron

    According to Elon, they will be testing further revisions first.

  • Michael Halpern

    true, but they validate the core technology with the 2

  • Kirk

    Do we know when to expect them to start launching the constellation in earnest? Gwynne Shotwell recently said they expected their launch cadence to drop in 2019 to about that of 2017 (18 launches), I’m assuming Starlink won’t start going up until 2020.

  • Michael Halpern

    No

  • Michael Halpern

    I think Starlink will be the payloads for the “same rocket twice in 24hrs” thing

  • Kirk

    That would make a lot of sense, at least for the second flight. I could see the first flight being a commercial satellite or a Dragon cargo resupply mission, launch RTLS out of Florida without any unusual schedule pressures, but with the Starlink payload ready to go from the other pad and HIF when the clock starts.

    Shotwell was talking in the context of commercial payload launches. Any Starlink demos or even operational flights would be on top of that ~18.
