aren't most galaxies disc shaped ? Not very hard to imagine that since gravity is the force that rules over galaxies, solar systems and planets, then the distribution of stars around the massive object in the galaxy, the distribution of planets around a star, and the rings around a planet, is all from the same force, not that all objects are enligned in the same plane, but generally within one system(galaxy, solar system, or planet) well it all seems to stretch into a disc. Maybe if the massive thing at the middle wasn't rotating it wouldn't spread out into a disc, i'm no astrophysician.

The first ones were. There are a number of scientists that argue more cheap small rovers would yield more science than large expensive singular rovers, but so far they're not winning the NASA awards for contracts. I think we'll start to see more diversity of size in the future awards, given how successful small satellites are becoming.
