Mars Express captures purple swirls at south pole ice cliff

Cliffs formed by ancient Martian tectonic activity

1 Sep 16 · 7d ago · 1 post · 1 source · development 1 of 2

Thyles Rupes's rocky cliffs reach over 1 km tall and formed through tectonic processes when two parts of Mars's crust pushed together, causing one to rise above the other. This occurred billions of years ago as Mars's cooling interior contracted and deformed the crust. Unlike Earth, present-day Mars lacks active tectonics.

“Mars isn't always red. New images from Mars Express reveal striking purple swirls near the planet's south pole.”
