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.
