A European Space Agency mission has captured images from deep inside the largest known canyon in our Solar System.
The pictures from the Mars Express show the Valles Marineris. This is almost ten times longer, 20 times wider, and five times deeper than the Grand Canyon in the US.
The images show that the canyon is formed of mountains, dark dunes, and landslides.
The photos were taken in April during the Mars Express’ High-Resolution Stereo Camera or HRSC.
The canyon covers around 4,300km of Mars’ equator and is 7km deep in some parts.
The images show that there are two trenches that run alongside Valles Marineris – also known as chasma.
