The North Polar Basin, more commonly known as the Borealis Basin, is a large basin in the northern hemisphere of Mars that covers 40% of the planet. [1] [2] Some scientists have postulated that the basin formed during the impact of a single, large body roughly 2% of the mass of Mars, having a diameter of about 1,900 km (1,200 miles) early in the history of Mars, around 4.5 billion years ago.
[2] [3] [4] This primordial ocean, dubbed Paleo-Ocean [1] or Oceanus Borealis (/ oʊ ˈ s iː ə n ə s ˌ b ɒ r i ˈ æ l ɪ s / oh-SEE-ə-nəs BORR-ee-AL-iss), [5] would have filled the basin Vastitas Borealis in the northern hemisphere, a region that lies 4–5 km (2.5–3 miles) below the mean planetary elevation, at a time period of ...
Vastitas Borealis (Latin for 'northern waste') [1] is the largest lowland region of Mars. It is in the northerly latitudes of the planet and encircles the northern polar region . [ 2 ] Vastitas Borealis is often simply referred to as the northern plains , northern lowlands or the North polar erg [ 3 ] of Mars.

LOS ANGELES (Reuters) -NASA's rover Perseverance has gathered data confirming the existence of ancient lake sediments deposited by water that once filled a giant basin on Mars called Jerezo Crater ...
The region is in the broader North Polar/Borealis Basin that covers most of the Northern Hemisphere of Mars. The Utopia basin is estimated to have formed around 4.3-4.1 billion years ago. [6] [7] The impactor was likely around 400–700 kilometres (250–430 mi) in diameter. [8] [9] [10] The basin was subsequently mostly filled in, resulting in ...
Olympia Undae lies within the informally named Borealis basin (also called the north polar basin [4]), the largest of three topographic basins that occur in the northern lowlands of Mars. [5] The average elevation in Olympia Undae is about 4,250 m below datum (martian "sea" level). [6]
