Global Resurfacing of Venus
The impact cratering record on Venus is unique among the terrestrial planets. Fully 84% of the craters are in pristine condition, and only 12% are fractured. Remarkably, only 2.5% of the craters andExpand

Timing of the Martian core dynamo
[1] Using the radial component magnetic data acquired by Mars Global Surveyor during its mapping phase, a reliable magnetic anomaly map of Mars is derived. Many weak but reliable magnetic anomaliesExpand

Paleomagnetic pole positions and pole reversals of Mars
The paleomagnetic pole positions of Mars obtained by modeling 10 small-size, isolated magnetic anomalies show considerable clustering, 7 out of 10 are within a circle of 30 degrees radius centered atExpand

A 50‐degree spherical harmonic model of the magnetic field of Mars
This paper presents a 50-degree and order spherical harmonic model of the magnetic field of Mars derived at 120-km altitude using the three orthogonal components of the vector magnetic field dataExpand

Magnetization of the Martian crust
[1] This paper presents the lateral variations of the vertically averaged magnetization model of the Martian crust determined from the degree 50 spherical harmonic model of the magnetic potential.Expand

A coherent model of the crustal magnetic field of Mars
[1] The immense amount of the mapping-phase Mars Global Surveyor (MGS) magnetic data allows us to derive a highly accurate magnetic map of Mars. The data acquired at nighttimes within the first ∼3Expand

Lunar mascons revisited
The entire spectra of the surface topography and gravity field of lunar mascons are well presented by the high-resolution Clementine data. The negative correlation between the topography andExpand

Paleomagnetic poles of Mars: Revisited
[1] The huge amount of data acquired by Mars Global Surveyor during its mapping period provides a unique opportunity to reassess the paleomagnetic pole positions of Mars previously determined on theExpand

Impact demagnetization of the martian crust
Abstract The lack of magnetic anomalies within the giant martian impact basins, Hellas, Argyre, and Isidis suggests that the impacts demagnetized the crust. Our analysis of the magnetic anomalyExpand

Magnetic crust of Mars
[1] The strong magnetic anomalies of Mars require highly magnetic sources in the crust. The bottom of the potentially magnetic layer is constrained by the Curie temperature of its magnetic carriers,Expand
