A specific subtrope of La Resistance.
You know it, you love it! La Resistance- space colony style. The red planet, the moon, or some other outpost of the Terran mother civilization rebels against the colonial oppression of Earth! The Revolutionary War (sometimes the Civil War) of The Future. The ur-example of this is are the mutant Martian revolutionaries in "Total Recall," though I suggest we name the trope for the slogan from the ever popular Marsie Revolutionaries on Babylon 5: "Free Mars!"
