Part 2: Martian Terrain & Moons
Red planet's profile
Reull Vallis
A region close to
Ma'adim Vallis, one of the largest canyons on Mars, finding craters, lava flows and tectonic features.

Olympus Mons is
the largest volcano in the Solar System. Olympus Mons rises
24 km high and measures
550 km across. By comparison, Earth's largest volcano, Mauna Loa in Hawaii, rises 9 km high and measures 120 km across.
Such large volcanoes can exist on Mars because of the low gravity and lack of surface tectonic motion.
Valles Marineris is the longest and deepest canyon in the Solar System. It is
4000 km long,
200 km wide, and up to
7 km deep. It runs along the Martian equator and covers nearly a quarter of the planet's circumference and 59% of its diameter.
Lol Mars is an extreme place. Earth's deepest canyons and highest mountains pale in comparison.
Many pictures of Martian craters, moons, fields and valleys can be found @
HiRISE (High Resolution Imaging Science Experiment).
Deimos and Phobos - Martian moons.
