MARS

The only planet we know of
inhabited entirely
by robots.

EXPLORE MARS

THE FOURTH PLANET

The fourth planet from the Sun and the
second-smallest planet in
the Solar System, being
larger
than only Mercury.

Mars carries the name of
the Roman god of war and
is often referred to as the
"Red Planet".

The latter refers to the
effect of the iron oxide
prevalent on Mars's
surface, which gives
it a reddish appearance
distinctive among the
astronomical bodies
visible to the naked eye.

MARS AND
ITS CRETERS

Mars is a terrestrial planet with a thin
atmosphere, with surface features
reminiscent of the impact
craters of the Moon and the valleys,
deserts and polar ice caps of Earth.

TRAVALERS OF
THE FUTUR

Travelers of the Future, Beware! Mars
is no place for the faint-hearted.

Arid, rocky, cold and apparently
lifeless, the Red Planet offers few
hospitalities.

Fans of extreme
sports can rejoice, however, for the
Red Planet will challenge even the
hardiest souls among us.

Home to the largest volcano in the
solar system, the deepest canyon and
crazy weather and
temperature patterns, Mars looms as
the ultimate lonely planet
destination.
