I'm surprised that the United States doesn't have laws prohibiting the launch
of such payloads by private launch operators. After all, I'm sure they have
restrictions on launching, say, Earth observation satellites with mirrors
above a certain size.

So SPACE is US property ?
I thought only the moon was.

No, but if the U.S. had such laws, they would have at least hindered this launch
by a U.S. artist. It is certainly true that other countries that launch
satellites into space ought to have such policies - if they do not already. From
this news item, it could only be inferred that the United States was lacking
such a restriction.

That one is quite tame really. This is the one to be really worried
about - Chengdu plan to launch an illumination satellite that is 8x
brighter than a full moon and with a ground footprint of 10-80km.

That really will spoil your deep sky imaging when it goes past!

Since they want to save money on street lighting in Chengdu, maybe it will be
geosynchronous.
