Phobos-Grunt experiments to measure Phobos' librations
, 2011 In the frame of the Russian Phobos-Grunt mission, Phobos librations will be measured with enough precision such that crucial constraints will be obtained on the geophysical properties of its interior, offering key information on its origin [1]. This study assess the precision that can be obtained on Phobos physical librations and discuss the knowledge ...

Spacecraft exploration of Phobos and Deimos
Planetary and Space Science, 2014 We review the previous exploration of Phobos and Deimos by spacecraft. The first close-up images of Phobos and Deimos were obtained by the Mariner 9 spacecraft in 1971, followed by much image data from the two Viking orbiters at the end of the 70s, which

Journal of Geophysical Research E: Planets, 2021 International audienceWe characterize the solar wind proton reflection (backscattering) from Phobos using a series of Mars Express operations. The plasma data obtained during the Phobos flyby of Mars Express in January 2016 showed a non-solar wind signal

Radar echoes from the martian satellite Phobos provide information about that object's surface properties at scales near the 3.5-cm observing wavelength. Phobos appears less rough than the moon at centimeter-to-decimeter scales. The uppermost few decimeters of the satellite's regolith have a mean bulk density within 20% of 2.0 g cm

Interpretation of the surface brightness of Phobos
Planetary and Space Science, 1991Analysis of disk resolved images of Phobos obtained by the Phobos 2 spacecraft allows us to study the surface scattering law and albedo variations. From low phase angle images we find variations in local geometric albedo 10%, with a correlation length 1km. The scattering law is reasonable well matched by the recent proposed LPI (Lumme et al.
