Last week we released our next set of notebooks based on the SpaceX tourist poster series featuring Olympus Mons, Valles Marineris, and Phobos & Deimos. Today we're sharing a bit more information about Valles Marineris which also appears in the notebooks.
Valles Marineris is 4,000 km long and reaches depths of up to 7 km. In comparison to something that we consider an amazing piece of geography on Earth, the Grand Canyon in Arizona is only about 800 km long and 1.6 km deep.
It seems Mars does everything bigger.
The canyon system is thought to be as a result of a crack in the Martian crust as the planet cooled, and further exposed through erosion and the possibility of once flowing water or moving glaciers.
If you thought that was interesting then there's 2 other notebooks in the set to go along with Valles Marineris — namely Olympus Mons and Phobos & Deimos. We'll be sharing the last of those stories on Olympus Mons next week.
If you're interested in picking up a set today for yourself, a loved one, a friend, or if you're sucking up to your science teacher then get your set today.
