This time, they’re from Australian and caused by the SpaceX Falcon9 rocket that went up last Friday.

That spiral look familiar? It might remind you of something similar that popped up over Norway last year that turned out to be a failed Russian rocket test.

The key difference being that the Falcon9 was supposed to be doing that, and the Russian rocket wasn’t. Ok, when I say that the Falcon9 was “supposed” to be doing that, I mean that the rocket was only designed to reach a set altitude then crash out safely in the Pacific Ocean. The spiral over Australia was the Falcon9 on it’s way to crashing out.
