A Mystery About the Moon’s Deep Interior Endures

by Laurent G. J. Montési 25 July 202318 July 2023

Geophysical data has suggested that the base of the Moon’s mantle is partially molten or contains ilmenite, but an improved rheology model puts the existence of this layer in doubt.

Meteor Impact Could Inform Martian Mysteries

by Caroline Hasler 16 December 202216 December 2022

The impact sent surface waves rippling over the Martian surface all the way to NASA’s InSight lander, giving scientists a rare view of the planet’s outer layer.

Powerful Impact Provides Insight into Deep Structure of Mars

Rachel Fritts, Science Writer by Rachel Fritts 14 November 202214 November 2022

Seismic signals detected by the InSight lander show that the planet’s lower mantle may be less homogenous than previous models have suggested.

Ceres: Missing Craters, Crust Thickness Variation by Interior Convection

by Bethany Ehlmann 18 July 202217 February 2023

Models show that several puzzling features about Ceres’ topography, gravity anomalies, and crater size distribution may be explained by asymmetric hemispherical convection due to radiogenic heating.

Flipping the Sequence of Martian Formation

Damond Benningfield, Science Writer by Damond Benningfield 15 July 202219 July 2022

Analysis of the Chassigny meteorite suggests the planet acquired most of its interior volatiles from meteorites, not from the solar nebula.
