Yes, yes they do work. That's why it's a billion dollar industry. It allows industries to micro-target specific ads for communities and speak to them directly. It gives you more ability to expand your brand to new customers, not l

Because it is really that easy. Space-junk in low-earth orbit is not really a concern, and alarmist articles about space-junk in connection with projects like Starlink are just click-bait that rely on the general public's ignorance of

With the CubeSats revolution there aren't a lot of unknown unknowns. The risks are clear, and the benefits far outstrip them. Again, as mentioned above, Kessler Syndrome is of little threat in the low earth orbit which CubeSats operate
