A mission concept of Phobos/Deimos exploration [PDF]

open access: yes, 1993
We have been designing the concept of Phobos/Deimos mission using the Japanese H-2 rocket as a first step in asteroid exploration. In planning the mission concept, we focused on development of methods to characterize the materials of Phobos/Deimos.

Effect of oxygen ion irradiation on the visible, infrared, and Raman spectra of Phobos candidate materials: implications on the space weathering by Martian atmosphere-derived ions

open access: yesProgress in Earth and Planetary Science
The origin of Martian satellites is still under debate. Nevertheless, such information could give insights into the evolution of the Martian system and planetary formation processes.

The PHOBOS experiment

open access: yes, 1995
PHOBOS is an experiment designed to study Au-Au collisions at RHIC. The apparatus consists of a 4{pi} multiplicity array and two spectrometer arms. The experiment is designed to measure the polar and azimuthal angles of most particles produced in the collisions and whether they are charged particles or photons.

Phobos: Close encounter imaging from the Viking Orbiters [PDF]

open access: yes, 1984
The shape and orbital characteristics of Phobos, the larger and innermost of Mars' two irregular moons, are discussed and illustrated. Also presented are the high resolution pictures of Phobos that were obtained during the close flybys of Viking Orbiters

Surface science on Phobos with the navigation cameras of the MMX IDEFIX rover

open access: yesProgress in Earth and Planetary Science
A CNES/DLR rover called IDEFIX will be deployed on the surface of Phobos in late 2028 or early 2029 as part of JAXA’s Martian Moons eXploration (MMX) mission.

Infrared-to-visible albedo ratio of Phobos

open access: yesAstronomy & Astrophysics
Aims. The ratio between infrared and visible albedo, pIR/pV, provides a simple proxy for the spectral slope of asteroid surfaces between the visible and near-infrared wavelength ranges.

The motion model of Phobos and the technique of determination of parameters in the Phobos-Grunt project

open access: yes, 2008
: The SC flight named Phobos-Grunt is planned to 2009 in Russia with purpose to deliver to the Earth samples of a ground of the Mars’s satellite Phobos.

Illumination Conditions and Thermal Modeling for the Martian Moon Phobos [PDF]

open access: yes, 2019
We study the thermal conditions in the polar areas of the irregularly shaped Martian moon Phobos. As was previously discussed, we consider direct illumi- nation by the Sun, eclipses by Mars, Mars shine, and single scattering of solar light by other
