Civilian Satellites to enter Into Very Low Earth Orbit

Recommendable! It might get a lot busier in earth orbit. However, this development seems to be in a very early stage.

"The first commercial very low-Earth orbit (VLEO) satellite will probably launch before the end of December, depending on how things go at China Aerospace Science and Industry Corporation (CASIC) and EOI Space. Both companies claim they are leading the way on an over-the-horizon idea that will bring satellites more down-to-Earth than today’s fast-growing low Earth orbit (LEO) satellite constellation.
VLEO refers to orbits between about 100 kilometers and 300 or 400 km (although the exact range depends on who you ask), in contrast to LEO, which starts around 300 or 400 km and extends up to 2,000 km. The first satellites in VLEO were short-lived US spy satellites in the 1960s and 1970s ...
“The telecoms industry is quite interested in VLEO, particularly for its low latency,” ...

Telecoms companies will be able to shift some of their ground-based cellular and emerging LEO-based cellular infrastructure into VLEO ...
CASIC plans 300 such satellites by 2030, according to Space News. Keeping them in VLEO will require almost continuous thruster boosts, because atmospheric drag pulls satellites out of VLEO within six months to a year. ...
new propulsion technology for VLEO and materials that can withstand the corrosive effect of the atomic oxygen in VLEO ...
when they reach the end of their useful life, they will burn up faster, which helps to minimize space junk and odds that a cascade of collisions could ripple outward ..."
