Human exploration of Phobos [PDF]
2015 IEEE Aerospace Conference, 2015 This study developed, analyzed, and compared mission architectures for human exploration of Mars' moons within the context of an Evolvable Mars Campaign. METHODS: All trades assumed conjunction class missions to Phobos (approximately 500 days in Mars system) as it was considered the driving case for the transportation architecture.

MAVEN Proton Observations Near the Martian Moon Phobos: Does Phobos Backscatter Solar Wind Protons?
Geophysical Research Letters, 2022 ESA's Mars Express (MEX) may have observed twice solar wind protons backscattered by Phobos. However, these detections remain uncertain and call for an independent confirmation.

Phobos DTM and Coordinate Refinement for Phobos-Grunt Mission Support [PDF]
, 2010 Images obtained by the High Resolution Stereo Camera (HRSC) during recent Phobos flybys were used to study the proposed new landing site area of the Russian Phobos-Grunt mission, scheduled for launch in 2011 [1]. From the stereo images (resolution of up to 4.4 m/pixel), a digital terrain model (DTM) with a lateral resolution of 100 m per pixel and a ...

Observations of Phobos and its shadow: Implications for the Phobos orbit [PDF]
, 2007 The orbit of Phobos deep in the gravity field of Mars is strongly affected by various parameters of the Mars interior. The orbit of the small satellite is therefore complex and undergoing a particulate tidal evolution. Our early analysis of im-ages from High Resolution Stereo Camera / Super Resolution Channel (HRSC/SRC) on Mars Express (MEX) [4] have ...
