I blame the Cassini spacecraft for not being able to concentrate on work today.
The scale of this space mission is short circuiting my earth bound brain. Cassini blasted out of the stratosphere, navigated 2.2 billion(!!!) miles while avoiding extra-terrestial debris, carefully settled into Saturn's orbit, and is now transmitting photos? Those pictures are incredible. How is it that my digital prints come out fuzzy, but photos from 7 light years away can be so beautiful? Are they for real?
Ever wondered what creates those gaps between the rings of Saturn? I hadn't really, but now I know. The rings are made of a parade of space-matter and Mini-moons/Moonlets orbiting Saturn. The gravitational force of the Moonlets draws the space-matter towards the little moons. Gaps appear as the matter is marshaled into the Moonlet's orbit. As the Moonlet and sheparded space-matter continue their parade around Saturn, a swath is cleared between the rings. Not the best explanation, but a neat phenomena that makes for a jaw dropping photo-op.
If this was a NYC parade of space-matter, in addition to the Moonlet Parade Marshals, there would be Moonlet Demonstrators, Moonlet Legal Observers, and Big Baton Wielding Moonlets on horses.
Happy long weekend everyone!
