<p>The origin of the Martian moons, Phobos and Deimos, remains elusive. While the morphology and their cratered surfaces suggest an asteroidal origin, capture has been questioned because of potential dynamical difficulties in achieving the current near-circular, near-equatorial orbits. To circumvent this, in situ formation models have been proposed as alternatives. Yet, explaining the present location of the moons on opposite sides of the synchronous radius, their small sizes and apparent… 

A lighter core for Phobos?

Context. The origin of the Martian moons Phobos and Deimos is still poorly understood, and is the focus of intense debate. Aims. We demonstrate that a stratified internal structure of Phobos is

Cold Atom Interferometry for Enhancing the Radio Science Gravity Experiment: A Phobos Case Study

Interplanetary missions have typically relied on Radio Science (RS) to recover gravity fields by detecting their signatures on the spacecraft trajectory. The weak gravitational fields of small

Challenges in Forming Phobos and Deimos Directly from a Splitting of an Ancestral Single Moon

The origin and evolution of Martian moons have been intensively debated in recent years. It is proposed that Phobos and Deimos may originate directly from the splitting of an ancestral moon orbiting

Tidal rigidity of Phobos

An ongoing satellite-ring cycle of Mars and the origins of Phobos and Deimos

The Martian moons Phobos and Deimos may have accreted from a ring of impact debris, but explaining their origin from a single giant impact has proven difficult. One clue may lie in the orbit of

The origin of the Martian moons revisited

The origin of the Martian moons, Phobos and Deimos, is still an open issue: either they are asteroids captured by Mars or they formed in situ from a circum-Mars debris disk. The capture scenario

The rheology and thermal history of Mars revealed by the orbital evolution of Phobos

TLDR
Predicting the long-term evolution of the main envelopes of Mars and exploiting the relationship between Mars and Phobos within an established in situ scenario for the early origin of the moons of Mars find that Mars was moderately hotter than it is today, and its mantle sluggishly deforms in the dislocation creep regime.

Rotational motion of Phobos

Context. Phobos is in synchronous spin-orbit resonance around Mars, like our Moon around the Earth. As a consequence, the rotational period of Phobos is equal in average to its orbital period. The

Tidal disruption of Phobos as the cause of surface fractures

Phobos, the innermost satellite of Mars, displays an extensive system of grooves that are mostly symmetric about its sub‐Mars point. Phobos is steadily spiraling inward due to the tides it raises on
