I'm convinced we're some of the last people who will be able to see star constellations, you can look up at the sky at almost any moment and find a satellite. How long before star constellations become unrecognisable due to satellites passing through them? What will the night sky look like in 500 years? In my childhood there were none, now there are thousands. Every time I point one out people spurt out "international space station" as if that's the only thing floating around up there.
