Surface environment of Phobos and Phobos simulant UTPS [PDF]
Earth, Planets and Space, 2021 The Martian Moons eXploration (MMX) mission will study the Martian moons Phobos and Deimos, Mars, and their environments. The mission scenario includes both landing on the surface of Phobos to collect samples and deploying a small rover for in situ ...

High-resolution shape models of Phobos and Deimos from stereophotoclinometry [PDF]
Earth, Planets and Space, 2023 We created high-resolution shape models of Phobos and Deimos using stereophotoclinometry and united images from Viking Orbiter, Phobos 2, Mars Global Surveyor, Mars Express, and Mars Reconnaissance Orbiter into a single coregistered collection.

Precise Orbit Determination of MEX Flyby Phobos Using Simulated Radiometric and Image Data [PDF]
Sensors, 2021 A navigation camera or topography camera is a standard payload for deep space missions and the image data are normally used for auto-navigation. In this work, we study the potential contribution of image data in precise orbit determination for deep space

Excitation of Tumbling in Phobos and Deimos. [PDF]
Icarus, 2020 Mass-spring model simulations are used to investigate past spin states of a viscoelastic Phobos and Deimos. From an initially tidally locked state, we find crossing of a spin-orbit resonance with Mars or a mean motion resonance with each other does not excite tumbling in Phobos or Deimos. However, once tumbling our simulations show that these moons can

The importance of Phobos simulants: a review on our current knowledge
Frontiers in Astronomy and Space Sciences, 2023 Phobos, a satellite of Mars, was successfully studied by flyby, orbiter, and landing missions to the Red Planet, but several questions remain about its origin, composition, and relationship to Mars.

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