Personally I think it's awesome, I'm going to try to track it and show it to my daughter. I hope one day we'll have structures on the moon that are visible to the naked eye! Can you imagine how motivating and achievable that would make space exploration seem to a new generation.
Imagine explaining this to your daughter :
- Here is the ISS, people live there.
- This is the Hubble space telescope, it makes plenty of nice pictures.
- This is a communication satellite, it for making phone calls from anywhere in the world.
- This... is a giant disco ball, it is made so you can see it.
Putting up what is essentially a space billboard is the kind of space development we can do without. And this is what astronomers are complaining about. It is not for the object itself, it is for the precedent it sets.
