How much would it cost an international collaboration of citizen scientists to intentionally launch a Kessler Syndrome causing bunch of shotgun cubesats? How much would commercial opperations pay to stop it? How many people would go to prison for pointing out the bloody obvious?
@_thegeoff it is quite difficult to get a citizen science project to launch something to space. One of our club members did it about 20 years ago, but that was barely scratching the 100 km... Nobody ever got something to orbit. So the 400 to 600 km LEO is pretty much out of reach.

@carstenfranke You don't have to get to orbit to be an anti-satellite missile. But, yeah, 400 to 600km is a bit tricky.
