Earth is Earth, the Moon is the Moon, Venus, Jupiter, Saturn, they're all the same, and Mars, Mars is gone.
While Earth remains relatively peaceful, friendly and clean, it's not really any different than it ever has been. The light side of the Moon is a spitting image of the United States in the 1920's - organized crime runs rampant, crooked cops don't know how to fix things, and prohibition is providing great business for the Lunar Syndicate. Smuggling from Earth to the Moon is Orbital Policing Systems biggest problem, but the Rogue Moon Smuggling Ring is hiring younger, faster smugglers, and things are getting violent.
The dark side of the Moon has turned into a well organized, twilight wonderland of fountains, and bleak, monotonous architecture. It's too organized. It's too logical. It's communism.
The UMJ, the United Moons of Jupiter, are the solar systems most profitable industries, whether mining gas on Jupiter itself from the smaller moons, or harvesting water from the large moons. Colonization runs rampant and an effort to terraform the majority of the moons and create an idyllic community is underway.
Outsourcing earth industry to Jupiter is a great idea, it will help preserve Earth's precious ecosystem, and turn the third planet back into a paradise for humans.
Venus is under study, and houses science stations. Lots of science stations. Nothing but science stations.
And Mars, is missing. It's gone. No traces, no nothing. It left town (scientists theorize a massive wormhole swallowed it, conspiracy theorists say it was aliens). We spent thirty years terraforming it, and then ... it bailed and handed off the kids, Phobos and Deimos, to Earth.
Scientists speculate it was engulfed by a black whole. Conspiracy theorist say aliens stole it ...
So now we have three moons. One is like a gangster flick, one is bought and paid for property of SeruCon industries and the other is a Park.
