Martian colonies in season 4 of The Expanse

Although Mars is one of the three competing powers in universe of The Expanse TV series (a political sci-fi detective set a few centuries in the future where humans have colonized the entire Solar system) only a few scenes were actually set on Mars in first three seasons of the series. That changes in season 4 where the life on Mars at last gets proper depiction.

In The Expanse Mars, governed by Martian Congressional Republic, is a militaristic and technologically advanced society of over nine billion inhabitants. It is the major competitor of Earth & Luna, governed by United Nations. Earth, dragged down by overpopulation and climate change, envies Mars because of its society's high mobilization towards the shared goal of terraforming Mars. But in season 4 that shared goal and order of the Martian society is starting to erode as the new habitable planets beyond the rings are discovered (without the costly need of being terraformed as Mars does). As the interplanetary military tension is over veterans find themselves needless in the peace time society; crime and corruption is rising, and some even manage to sell older military tech to Belter pirate gangs.
