Maybe they monitor radiations.
I had a very vivid dream last night. I was at a family reunion outside during the day with a clear sky. Then I started seeing UFOs (the classic saucer-shaped). They were flying slow and low (below hundred feet) and they were rather small (no more than 10 feet in diameter). One landed and I was able to dismantle and examine it. It was a small one (2 feet diameter). It looked like an automated machine surveying the Earth. I woke up, remembered my dream, and the feeling I had was that they were some kind of robots sweeper for the atmosphere, maybe for radiations.
I never dreamed of UFOs before. And I rarley have dreams as vivid as this one.
