Sorry if I'm being too nitpicky here, but NASA isn't actually innovating on size, here. They're putting everything in the standard 10cm^3 cubesat envelope. And

Sorry if I'm being too nitpicky here, but NASA isn't actually innovating on size, here. They're putting everything in the standard 10cm^3 cubesat envelope. And they can fit a whole lot more than 10 satellites in the mass+volume of a typical one. And they can basically stow away on a rocket whose primary mission is one of those larger satellites.
