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.
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.
Chasma Boreale is a large canyon in Mars's north polar ice cap in the Mare Boreum quadrangle of Mars at 83° north latitude and 47.1° west longitude. It is about 560 km (350 mi) long and was named after a classical albedo feature name. [ 1 ]
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]
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 ...
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 ...
Additional processes could create those deviations from circularity. If the proposed Borealis basin is a depression created by an impact, it would be the largest impact crater known in the Solar System. An object that large could have hit Mars sometime during the process of the Solar System accretion.
An applicant proposes a special event venue at 1761 Bone Camp Road in Mars Hill. The Madison County Board of Adjustment will vote whether to approve a permit for the venue in its April 22 meeting.
