Dawn Above Arsia Mons and Its Ice Cloud
An artistic rendering of the Arsia Mons Elongated Cloud. The cloud is observed from orbit, but this viewpoint and many atmospheric details are illustrative.
THE OBSERVATION
What we can actually establish.
Mars Express and other orbiters have tracked a seasonal water-ice formation extending up to about 1,800 kilometers from the Arsia Mons region.

FROM THE SCIENCE STORY
The investigation behind the image.
Scientists have traditionally modeled Martian water-ice clouds as forming on airborne dust. A 2026 study showed that adding direct homogeneous ice nucleation from vapor can better reproduce the cloud’s sharp, trailing structure. Wind then transports the new particles away from the localized region where they first formed.
The simulations do not perfectly match every measurement; the proposed nucleation process has not been confirmed by sampling the crystals as they form.
