   Very much not a new idea: <a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Very_low_Earth_orbit" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Very_low_Earth_orbit

   Though fun to see. More interesting than the station keeping (indefinite part) is that it enables ~100km orbits, which are ~5x closer than what remote sensing satellites use today and thus could get 5x the resolution for the same instrument.

      100km is the height where meteoroids ablate. You must mean 100k miles and even there the largest meteors start to become visible.

      Indeed at the bottom tfb quotes heights of 190-250km for model calculations.
