Is it right to let a small number of very wealthy entrepreneurs fill Earth's already crowded orbital space to establish non-terrestrial internet monopolies? What are the risks, and are the costs justified? Should orbital space be a public good?

A few years ago I read a Sci-fi novel where the moon breaks into three parts. Everyone oohs and ahhs at the beauty of the new multiple moon system until it becomes apparent the new moons are colliding, creating hundred of smaller pieces. The pace of collisions increases chaotically towards a tipping point as the number of rocks increases, until the space debris starts bombarding the earth, wiping out life on the planet. Devasting stuff, and very unlikely.

But there is a genuine scientific parallel.

There are already millions of pieces of space junk orbiting the planet – ranging from broken satellites to discarded space gloves, some spanners and lots of flecks of paint that's broken off spaceships. These orbit at stupendous speed. If they hit anything, they have the potential to cause enormous damage. If they destroy anything, then a single piece of debris can create a whole cloud of debris, each piece of which can cause similar damage, raising the potential of critical out of control chain reaction and a cloud of debris making space travel very dangerous.

Scary… if you are spaceman.

Many smart Tech investors consider the most valuable private company on the planet is Elon Musk's Space X and his internet constellation Starlink. There are a host of other firms also shooting for space-based coms dominance; including the UK government's recently acquired OneWeb, Jeff Bezos' Project Kuiper (funded by Amazon), ViaSat and Telesat. All of them want to launch satellites into low-earth-orbit to win a share of space-based internet.
