The origin of the Moon’s large-scale topography is important for understanding lunar geology, lunar orbital evolution and the Moon’s orientation in the sky. Previous hypotheses for its origin have included late accretion events, large impacts, tidal effects and convection processes. However, testing these hypotheses and quantifying the Moon’s topography is complicated by the large basins that have formed since the crust crystallized. Here we estimate the large-scale lunar topography and gravity… 

Evidence for lunar true polar wander and a past low‐eccentricity, synchronous lunar orbit

As first noted 200 years ago by Laplace, the Moon's rotational and tidal bulges are significantly larger than expected, given the Moon's present orbital and rotational state. This excess deformation

Formation of the Lunar Fossil Bulges and Its Implication for the Early Earth and Moon

First recognized by Laplace over two centuries ago, the Moon's present tidal‐rotational bulges are significantly larger than hydrostatic predictions. They are likely relics of a former hydrostatic

Planetary science: Signs of a wandering Moon

The presence of ice at two positions on opposite sides of the Moon suggests that the satellite's orientation was once shifted away from its present spin axis — a finding that has implications for the

Lunar true polar wander inferred from polar hydrogen

The hypothesis that true polar wander was caused by a low-density thermal anomaly beneath the Procellarum region implies that polar wander initiated billions of years ago and that a large portion of the measured polar hydrogen is ancient, recording early delivery of water to the inner Solar System.

Near/Far Side Asymmetry in the Tidally Heated Moon.

The Lunar Paleo‐Magnetosphere: Implications for the Accumulation of Polar Volatile Deposits

Analyses of lunar samples suggest the Moon once possessed a dynamo from ~4.25 Ga until perhaps as recently as 1 Ga, with surface field strengths between ~5 and 100 μT. While the exact timing,

The Lunar Fossil Figure in a Cassini State

The present ellipsoidal figure of the Moon requires a deformation that is significantly larger than the hydrostatic deformation in response to the present rotational and tidal potentials. This has



On lunar asymmetries 1. Tilted convection and crustal asymmetry

[1] It is proposed that lunar crustal asymmetries are the result of convective processes acting early in the Moon's history, during the magma-ocean phase and after synchronous rotation was

Forming the lunar farside highlands by accretion of a companion moon

According to the authors' simulations, a large moon/Moon size ratio and a subsonic impact velocity lead to an accretionary pile rather than a crater, contributing a hemispheric layer of extent and thickness consistent with the dimensions of the farside highlands and in agreement with the degree-two crustal thickness profile.

Asymmetric thermal evolution of the Moon

The Moon possesses a clear dichotomy in geological processes between the nearside and farside hemispheres. The most pronounced expressions of this dichotomy are the strong concentration of

Effects of orbital evolution on lunar ice stability

[1] Many regions near the lunar poles are currently cold enough that surface water ice would be stable against sublimation losses for billions of years. However, most of these environments are

The Crust of the Moon as Seen by GRAIL

The Moon's gravity field shows that the lunar crust is less dense and more porous than was thought, and high-resolution gravity data obtained from the dual Gravity Recovery and Interior Laboratory (GRAIL) spacecraft show that the bulk density of the Moon's highlands crust is substantially lower than generally assumed.

The Shape and Internal Structure of the Moon from the Clementine Mission

Global topographic and gravitational field models derived from data collected by the Clementine spacecraft reveal a new picture of the shape and internal structure of the moon, indicating that the structure and thermal history of the Moon are more complex than was previously believed.

Gravity Field of the Moon from the Gravity Recovery and Interior Laboratory (GRAIL) Mission

The Moon's gravity field reveals that impacts have homogenized the density of the crust and fractured it extensively, and GRAIL elucidates the role of impact bombardment in homogenizing the distribution of shallow density anomalies on terrestrial planetary bodies.
