I'm referencing the excellent book and TV series The Expanse. It's semi-hard sci-fi, set in the nearish future of our solar system, where there's a growing conflict over the resources of the asteroid belt and outer planets... Earth and Mars are in a murky cold war with each other, and a third faction- the microgravity-native Belters- are beginning to forge their own new society, in the outer reaches of the system.

The reference is a bit spoiler-y for book and season 2... >!When one of the Martian moons gets blown up, a main crew character "fixes" the Martian flag by turning its depiction of Phobos into a bunch of dots. Predictably, this pisses off the Martians.!<
