The Late Heavy Bombardment

Heavily cratered surfaces on the Moon, Mars, and Mercury show that the terrestrial planets were battered by an intense bombardment during their first billion years or more, but the timing, sources,

Interpreting the Cratering Histories of Bennu, Ryugu, and Other Spacecraft-explored Asteroids

Asteroid crater retention ages have unknown accuracy because projectile–crater scaling laws are difficult to verify. At the same time, our knowledge of asteroid and crater size–frequency

The timeline of the lunar bombardment: Revisited

Origin and implications of non-radial Imbrium Sculpture on the Moon

It is concluded that the Imbrium impactor was a proto-planet (half the diameter of Vesta), once part of a population of large proto-planets in the asteroid belt before depletion caused by the orbital migration of Jupiter and Saturn.

The fractured Moon: Production and saturation of porosity in the lunar highlands from impact cratering

We have analyzed the Bouguer anomaly (BA) of ~1200 complex craters in the lunar highlands from Gravity Recovery and Interior Laboratory observations. The BA of these craters is generally negative,

Cataclysm No More: New Views on the Timing and Delivery of Lunar Impactors

It is demonstrated that most evidence supports a prolonged lunar (and thus, terrestrial) bombardment from ~4.2 to 3.4 Ga and not a cataclysmic spike at ~3.9 Ga, and implications for the conditions required for the origin of life are addressed.

Number of Near-Earth Objects and Formation of Lunar Craters over the Last Billion Years

We compare the number of lunar craters larger than 15 km across and younger than 1.1 Ga to the estimates of the number of craters that could have been formed for 1.1 Ga if the number of near-Earth

Direct Detection of Projectile Relics from the End of the Lunar Basin–Forming Epoch

Analysis of lunar rocks from the Apollo missions reveals fragments from meteorites that hit the Moon in the ancient past, which suggests that primitive chondritic asteroids were common Earth-Moon–crossing impactors during the latter stages of the basin-forming epoch.

Cratering Records in the Inner Solar System in Relation to the Lunar Reference System

The well investigated size-frequency distributions (SFD) for lunar craters is used to estimate the SFD for projectiles which formed craters on terrestrial planets and on asteroids. The result shows

The Violent Collisional History of Asteroid 4 Vesta

Dawn observations confirm that Vesta is a small differentiated planetary body with an inner core, and represents a surviving proto-planet from the earliest epoch of solar system formation, and presents the mineralogical characterization of Vesta, revealing that this asteroid underwent a complex magmatic evolution that led to a differentiated crust and mantle.

Global Distribution of Large Lunar Craters: Implications for Resurfacing and Impactor Populations

The characteristics of pre- and postmare crater populations support the hypothesis that there were two populations of impactors in early solar system history and that the transition occurred near the time of the Orientale Basin event.

The Origin of Lunar Mascon Basins

High-resolution gravity data from the Gravity Recovery and Interior Laboratory spacecraft have clarified the origin of lunar mass concentrations (mascons), and free-air gravity anomalies over lunar impact basins display bull’s-eye patterns consisting of a central positive (mascon) anomaly, a surrounding negative collar, and a positive outer annulus.

An Archaean heavy bombardment from a destabilized extension of the asteroid belt

It is reported that the Late Heavy Bombardment lasted much longer than previously thought, with most late impactors coming from the E belt, an extended and now largely extinct portion of the asteroid belt between 1.7 and 2.1 astronomical units from Earth.

CRATER DEGRADATION OF KILOMETER-SIZED CRATERS ON THE LUNAR MARIA : INITIAL OBSERVATIONS AND MODELING

  • Geology
  • 2013
Introduction: Impact cratering at all scales has dominated the landscape evolution of the Moon in the period following the emplacement of the lunar maria. As a result, the degradation of craters on

Lunar impact basins: Stratigraphy, sequence and ages from superposed impact crater populations measured from Lunar Orbiter Laser Altimeter (LOLA) data

[1] Impact basin formation is a fundamental process in the evolution of the Moon and records the history of impactors in the early solar system. In order to assess the stratigraphy, sequence, and

Cataclysmic bombardment throughout the inner solar system 3.9–4.0 Ga

[1] Cohen et al. [2000] recently confirmed the hypothesis that the Moon was resurfaced by an intense period of impact cratering ∼3.9 Ga ago and, by inference, that the Earth also sustained

Ages and stratigraphy of lunar mare basalts in Mare Frigoris and other nearside maria based on crater size‐frequency distribution measurements

[1] We report on ages derived from impact crater counts for exposed mare basalt units in the northern part of the lunar nearside hemisphere (Mare Frigoris), the eastern and northeastern part of the
