Several of us stayed up late to watch the first Falcon Heavy night launch on youtube. The flames were more impressive than the daytime launches, but the synchronized landings of the side boosters was harder to follow.

Booth side boosters landed ok, and they almost caught the central booster, but it (just barely) missed the boat. We found out the next morning that they also caught one of the fairings in the net boat.

Once the payload section was in orbit they started releasing their satellites. As they did there were lots of occasional white blobs shooting by, just like the "stars" to in some movies, but of course they weren't stars. But what are they? Someone suggested that they were space junk or satellites, but that can't be right either. Low Earth Orbit may be crowded, but it's not that crowded. Our best guess is that they are bits of ice breaking loose from the ship (from moisture that condenses and freezes inside the fairing before launch, is protected by the fairing on the way up, and then breaks loose once it's in obit.

But why do they fly past then? Shouldn't they just drift away?
