Starlink: What isn't amazing?

 How do you place thousands of satellites in orbit
that can all manoeuver themselves
that each has a different freqnecy to avoid interference
that are constantly moving in groups in  and out of the user's field
that have a signal latency almost 100x less than the geostationary comm satellites
that are put in orbit with new designs almost every launch
that all stay up to date on the same software
with critical functions stored in the same memory sector
that survive radiation damage to data
that go through quality control feedback loops at every step
that integrate software code writing with design and launch
that are night and day modelling not just the parts but the whole system in boxed versions
that include a model of near earth space-time
and that constantly reconfigure the flying network to match changing conversation paths on earth.

A train of SpaceX Starlink satellites are visible in the night sky in this still from a video captured by satellite tracker Marco Langbroek in Leiden, the Netherlands on May 24, 2019, just one day after SpaceX launched 60 of the Starlink internet communications satellites into orbit. (Image credit: <a href="https://sattrackcam.blogspot.com/2019/05/wowowow-spectacular-view-of-spacex.html">Marco Langbroek via SatTrackBlog</a>)
