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 a mascon (a strong positive gravity anomaly ) detectable by orbiting satellites.
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.
The large basin is surrounded by heavily cratered highlands. The Argyre quadrangle is one of a series of 30 quadrangle maps of Mars used by the United States Geological Survey (USGS) Astrogeology Research Program. The Argyre quadrangle is also referred to as MC-26 (Mars Chart-26). [1] It contains Argyre Planitia and part of Noachis Terra.
One additional large basin, Utopia, is completely buried by northern plains deposits. Its outline is clearly discernable only from altimetry data. All of the large basins on Mars are extremely old, dating to the late heavy bombardment. They are thought to be comparable in age to the Imbrium and Orientale basins on the Moon.
The basin is located in the southern highlands of Mars and is thought to have been formed about 3.9 billion years ago, during the Late Heavy Bombardment. Studies suggest that when an impact created the Hellas Basin, the entire surface of Mars was heated hundreds of degrees, 70 meters of molted rock fell on the planet, and an atmosphere of ...
Badwater Crater is an impact crater located in Hellas Planitia and is situated within the low lying Plain of Peneus Palus on the southern hemisphere of Mars.It contains the lowest currently [as of?] known point on the entire planet, with an elevation of approximately −8,200 metres (−26,900 ft) [2] at 32.79° S, 62.14° E. [1] Badwater has a diameter of approximately 33.14 kilometres (20.59 ...
Atlantis basin is an eroded impact crater in the southern hemisphere of Mars, in the Phaethontis quadrangle, Sirenum Terrae region, centered at 177° West, 35° South. It was formed during the early Noachian period .
