    How many starlink satellites are/will be in orbit.

    Do the number of subscribers necessitate that number?

      As of September, SpaceX have deployed ~7,000 satellites out of a planned ~12,000 for the current constellation. They just passed 4 million subscribers in September as well.

      The number of necessary satellites is partly dictated by the number of subscribers in high density areas (max bandwidth) and partly dictated by the surface area of the Earth and the altitude of the orbit (global coverage). Since the Starlink constellation in VLEO, each satellite can service a much smaller region at any given time compared to a GEO satellite. VLEO has other advantages though, such as reduced latency and lower risk of Kessler syndrome.

        Can you estimate the total co2 emissions per launch/sattelite and per user?

        How many launches does it take total?

        Why not just build some very large/tall high-power towers?

        What’s the benefit of satellite internet?

          > Can you estimate the total co2 emissions per sattelite and per user?
          That needs a definition about user/time, so it is harder to do

          Per satelite is amount of sats/launches. its not perfect, but gives a reasonable answer.
          average seems to be 2Kton, 1.3Kton to 4Kton as low/high

          > How many launches does it take total? 210 till now, which i used for calculations above, how,
          to many variables i dare to give launches needed till 12k

            no, try doing in the middle of the ocean, and if that was cheap on land, it would already have been done, there where even subsidy to do that in most countries

            What’s the benefit of satellite internet?
            ppl where willing to pay >10X more for >10X lower data.
            Think having boats to get actual current weather information, or being to able to call for help on places where there is no connection.
