    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.

      Ideas require a ton of research to transform into reality.
