Latest Valles Marineris Stories
Long ago, in the largest canyon system in our solar system, vibrations from "marsquakes" shook soft sediments that had accumulated in Martian lakes.
A new study from ETH Zurich geoscientists Giovanni Leone, however, suggests that lava, rather than water or tectonic plate activity, cut the gigantic valleys into the red planet's landscape.
Beautiful streamlined islands and narrow gorges were carved by fast-flowing water pounding through a small, plateau region near the southeastern margin of the vast Vallis Marineris canyon system.
Ripped apart by tectonic forces, Hebes Chasma and its neighboring network of canyons bear the scars of the Red Planet’s early history.
Glide through part of the largest canyon on Mars, Valles Marineris, in this stunning color movie from ESA's Mars Express.
The European Space Agency (ESA) said that a new image taken by its Mars Express orbiter shows off flood events that took place on the Red Planet.
Dramatic underground explosions, perhaps involving ice, are responsible for the pits inside these two large martian impact craters, imaged by ESA’s Mars Express on 4 January.
Our planet has been mapped out and explored for the most part, but there are plenty of other planets out there waiting to be discovered.
For millenia, humans have been fascinated by our reddish planetary neighbor. However, in recent years scientists have developed the equipment to visualize some of the main surface features of Mars.
