"Preliminary design of a space debris removal mission in LEO using a solar sail"

We show how a solar sail could be used as a shuttle to collect and deorbit debris objects of moderate size, multiple times. The sail exploits the combined effect of solar radiation pressure and atmospheric forces.

Praises galore.

Best report found so far is confusing and says the rocket reached both 51 miles (90 km) and 91 miles (148 km), so maybe close to orbital height which can be as low as 100 miles (160 km), but not a danger to StarLink or other LEO satellites.

If it is that high up there where will it come down?

While we are talking about Musk and Starlink, let's discuss the Kessler Syndrome.

Some evening not too long from now you may look up, and instead of the stars and a few Starlink satellite trains marching along, you might see a night sky filled with brilliant sparkles. You check the news and learn the International Space Station has been destroyed as well humanity's weather and other Earth observation satellites. What's happened?

"The problem of space junk adds up to around 200 tons of our trash. The clutter in Earth's orbit includes defunct spacecraft, spent rocket boosters and items discarded by astronauts such as gloves, wrenches and toothbrushes."
