That first one is just satellites, though. If you use apps and/or sites like Heavens Above you can see exactly this fairly often. I've sometimes seen several at a time at night when walking the dogs. When I get home I look them up to identify what they were. Depending on where the sun is below the horizon and how clear the sky is, some nights it's almost impossible to not casually spot at least one, and other nights there are so many it's quite surprising. ISS always really stands out because it is relatively close and is much larger than other satellites. When you see more than one travelling in the same direction, they're nearly always a "train" which is basically what you get when they release a bunch of new satellites but they aren't in position yet. And if you're lucky, you can catch various units "chasing" the ISS with supplies. That doesn't explain the other two links, though. They are more connected to what people wanted from the report.
