Your costs are off. See my previous comment.

The problem isn't a 20% survival rate. This was a one-off event. The satellites were hit with a solar flare as they were deploying from the launch vehicle, causing them to never make it to design altitude or go into operations. Had SpaceX launched a day earlier or later, or even an hour earlier, then the satellites would have made it to a sustainable orbit.

All low Earth orbit objects are subjected to the impact of solar radiation and atmospheric heating. The result is that we move them around, such as the ISS. And most spy satellites.

Let's see.... Hmmmmm...... Sounds like a very interesting perspective to me. Yet using the very data you present, let's just stick with the Forbes article for now, there should be 5.4 alien civilizations in our galaxy that are in our range of the electromatic spectrum if 85% of matter is in the Dark Matter spectrum.

That just gave me a great idea. We should coin a new phrase, call it the DM Spectrum. Apply it to all the invisible stuff that dark matter could represent.

So.... back to the original focus of my comment - where are the other 5.4 civilizations that should be emitting signals in our EM Spectrum? Not caught up to us yet?
