The Mars Global Surveyor, active from 1997 to 2006, was the first spacecraft able to image Mars in high enough resolution to detect new impacts, with a resolution of up to 1.5 meters (4.9 ft). The first detected impact, a 14.4-meter (47 ft)-diameter crater in southern Lucus Planum, happened between 27 January 2000, and 19 March 2001. [2]
This is a list of craters on Mars. Impact craters on Mars larger than 1 km (0.62 mi) exist by the hundreds of thousands, but only about one thousand of them have names. [ 1 ] Names are assigned by the International Astronomical Union after petitioning by relevant scientists, and in general, only craters that have a significant research interest ...
The crater depth is 7,152 m (23,465 ft) below the standard topographic datum of Mars. [1] Hellas Planitia / ˈ h ɛ l ə s p l ə ˈ n ɪ ʃ i ə / is a plain located within the huge, roughly circular impact basin Hellas [a] located in the southern hemisphere of the planet Mars. [3] Hellas is the fourth- or fifth-largest known impact crater in ...
The bottom of the Jezero Crater – believed to have formed 3.9 billion years ago from a massive impact – is considered to be among the most promising areas on Mars to search for evidence of ...
The North Polar Basin on Mars is speculated by some to be evidence for a planet-sized impact on the surface of Mars between 3.8 and 3.9 billion years ago, while Utopia Planitia is the largest confirmed impact and Hellas Planitia is the largest visible crater in the Solar System.
The magnetic anomalies are weak or absent in the vicinity of large impact basins, the northern plains, and in volcanic regions, indicating that magnetization in these areas have been erased by thermal events. The presence of magnetic anomalies on Mars suggests that the planet maintained an intrinsic magnetic field early on in its history. [2]
The search for life on Mars hasn't yet turned up evidence, but recently a new potential means of finding some did emerge. NASA's Mars Reconnaissance Orbiter has detected the presence of impact ...
Frosted terrain on Utopia Planitia, taken by the Viking 2 lander in 1979. Utopia Planitia (Greek and Latin: "Utopia Land Plain") is a large plain [2] within Utopia, the largest recognized impact basin on Mars [a] and in the Solar System with an estimated diameter of 3,300 km (2,100 mi). [1]
