Location and Description
The scar cuts across the lower flank of Arsia Mons, one of Mars’ largest volcanoes. ESA describes it as “a dark, uneven scar slicing through marbled ground at the foot of a giant volcano.”

It also has steep walls on either side, creating a dramatic landscape.
Arsia Mons Volcanic Region
Arsia Mons, where Aganippe Fossa is located, is part of the Tharsis volcanic region on Mars. This area includes several colossal volcanoes, such as Olympus Mons, the tallest volcano in the known solar system.

Arsia Mons itself measures 270 miles in diameter and rises more than 5.5 miles above the surrounding plains.
Mars Express Mission
Mars Express, launched by the ESA in 2003, has been orbiting the Red Planet, providing valuable data. It captures detailed images of Mars’ surface, maps its minerals, and studies the composition and circulation of its atmosphere.

The mission continues to reveal fascinating aspects of Martian geology.
Geological Formation Theories
Scientists believe that Aganippe Fossa was likely formed as magma rising beneath the Tharsis volcanoes caused Mars’ crust to stretch and crack.

This process could have created the long, steep-walled ditch we see today. However, the exact timeline and details of its formation remain a mystery.
Comparison with Earth
For comparison, the highest dormant volcano on Earth is Ojos del Salado on the Argentina-Chile border, which almost 4.3 miles high.

In comparison, Arsia Mons is significantly larger, highlighting the scale of Martian geological features.
Ongoing Research
Scientists continue to study Aganippe Fossa and the Tharsis region to understand better how these massive geological structures formed.
