Groove formation on Phobos from reimpacting orbital ejecta of the Stickney crater

open access: yesEarth and Planetary Physics, 2022
Numerous linear grooves have long been recognized as covering the surface of Phobos, but the mechanisms of their formation are still unclear. One possible mechanism is related to the largest crater on Phobos, the Stickney crater, whose impact ejecta may ...

Space weathering effects and potential spectral alteration on Phobos and the Moon: Clues from the Fe content of olivine

open access: yesAstronomy & Astrophysics, 2023
Context. Olivine responds to space weathering in the fastest and most profound way, which results in significant space weathering spectral alteration effects (SWSAEs) on airless silicate bodies.

Qualification of the MMX Rover Locomotion Subsystem for the Martian Moon Phobos

open access: yesIEEE Aerospace Conference, 2023
Planetary rovers have proven their function and value for the Earth moon as well as Mars in the past decades. While these celestial bodies have a gravity of the same order of magnitude as the Earth, wheeled locomotion has never been performed on a body ...

Testing for the MMX Rover Autonomous Navigation Experiment on Phobos

open access: yesIEEE Aerospace Conference, 2023
The MMX rover will explore the surface of Phobos, Mars' bigger moon. It will use its stereo cameras for perceiving the environment, enabling the use of vision based autonomous navigation algorithms.

Rotational motion of Phobos [PDF]

open access: yesAstronomy & Astrophysics, 2012
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 variations of its rotational motion are described by oscillations, called physical librations, which yield information of its interior structure. The largest

Development of a new Phobos spectral simulant: spectral properties from visible to the mid-infrared range

open access: yesMonthly notices of the Royal Astronomical Society, 2023
Phobos is the target of Martian Moons eXploration (MMX) the next sample return mission of the Japanese space agency (JAXA). The mission will investigate the origin of Phobos and Deimos – the two martian moons, using a suite of dedicated instruments ...

MMX Rover Simulation - Robotic Simulations for Phobos Operations

open access: yesIEEE Aerospace Conference, 2022
The MMX Rover, developed by CNES and DLR, will fly to and explore the surface of the Martian Moon Phobos within the JAXA Martian Moon Exploration Mission. It will be the first wheeled locomotion system in a milli-g environment.

Modelling cometary meteoroid stream traverses of the Martian Moons eXploration (MMX) spacecraft en route to Phobos [PDF]

open access: yesEarth, Planets and Space, 2021
The Martian Moons Exploration (MMX) spacecraft is a JAXA mission to Mars and its moons Phobos and Deimos. MMX will be equipped with the Circum-Martian Dust Monitor (CMDM) which is a newly developed light-weight ( $$\mathrm {650\,g}$$ 650 g ) large area (

Phobos and deimos surface composition: Search for spectroscopic analogs

open access: yesMonthly notices of the Royal Astronomical Society, 2022
Phobos and Deimos, the two satellites of Mars were largely studied in the past using ground-based telescope and spacecraft data, although most of the data were obtained by opportunity observations performed by Mars dedicated orbiters.

Trajectory Optimization and Control Applied to Landing Maneuvers on Phobos from Mars-Phobos Distant Retrograde Orbits

open access: yesUniverse, 2023
This paper presents research on the application of trajectory design, optimization, and control to an orbital transfer from Mars–Phobos Distant Retrograde Orbits to the surface of Phobos.
