This is a time-lapse of NASA's AZURE rocket launch to research auroras and the upper atmosphere. I coincidentally witnessed the launch of the two rockets and their beautiful payload deployment travelling on MV Trollfjord on Vestfjord in Norway.
While we were watching the after-effects of a beautiful northern lights display, the rockets were launched from the Andøya Space Center only about 180 km away to the north. We saw two orange dots rise into the sky and disappear. A short while later strange lights and colorful, expanding clouds appeared I first did not have an explanation for. It looked like an alien attack ;)
A quick internet search showed that we had witnessed aurora research conducted by NASA:
