Naming Word for "Mars" in Sanskrit.

Mangala Valles is a complex system of criss-crossing channels on Mars, located in the Tharsis region originating in the Amazonian epoch. It is thought to be an outflow channel, carved by catastrophic and release of vast quantities of water across the Martian surface. This flooding was probably initiated by tectonic stretching and the formation of a graben at the channels' head, perhaps breaching a pressurized aquifer trapped beneath a thick "cryosphere" (layer of frozen ground) beneath the surface.[1][2][3][4][5]

Mangala Valles contains several basins which filled, then the overflow went through a series of spillways.[6] [7] One source of waters for the system was Memonia Fossae, but water also probably came from a large basin centered at 40 degrees S.[8] [9]

There are many wind-sculpted ridges or yardangs covering many of the surfaces in the Mangala Valles region.[10][11]

"Mangala" comes from the word for Mars in Sanskrit.

Mangala Valles is referred to in Michael Crichton's book Sphere. In Stephen Baxter's novel Voyage, it is the location of the first manned Mars landing.
