Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 3, September 2025.Abstract The internal structures of asteroids are estimated iteratively via a classic gravity‐field‐inversed method on the ground computer in the post‐mission phase due to a large amount of gravity data. This paper develops a flight‐information‐perceived approach that has a superb capacity for constructing the interiors of a differentiated celestial ...

Phobos: Low Velocity Impacts [PDF]
, 2014 Marss inner moon, Phobos, is located deep in the planets gravity well and orbits far below the planets synchronous orbit. Images of the surface of Phobos, in particular from Viking Orbiter 1, MGS, MRO, and MEX, reveal a rich collisional history ...

Motion Parameters Determination of the SC and Phobos in the Project Phobos-Grunt [PDF]
, 2007 The SC "Phobos-Grunt" flight is planned to 2009 in Russia with the purpose to deliver to the Earth the soil samples of the Mars satellite Phobos. The mission will pass under the following scheme [1-4]: the SC flight from the Earth to the Mars, the SC ...

, 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.

, 1993 Phobos at Sparta The significance of the cult of Phobos at Sparta is analysed, based on a passage in Plutarch's "Life of Cleomenes" on the building of a hieron, contemporary with a reform reinforcing the power of the ephors.

Research Notes of the AASAbstract In 1966, Iosif Shklovsky and Carl Sagan theorized that exospheric drag could explain Phobos’s rapid inspiral rate towards Mars if Phobos were hollow. Later observations revealed a slower orbital decay rate, and updated models can account for this rate via tidal friction.

Mass distribution inside Phobos: A key observational constraint for the origin of Phobos.
, 2011 International audienceIn this study, we construct models of the mass distribution inside Phobos. We explore the possible internal mass distributions, considering three kinds of material inside Phobos: rock, porous-rock and water-ice.

Studying MID-Range planar orbits around Phobos
, 2022 El objetivo de este artículo es buscar y estudiar órbitas planas intermedias para naves espaciales que viajan cerca de Phobos. El primer paso es una búsqueda numérica y clasificación de las órbitas naturales basada en el concepto de las “órbitas cuasi ...

Opportunities to observe solar eclipses by Phobos with the Mars Science Laboratory
, 2012 We have generated predictions for observing Phobos transits during the period 2012–2014 using the Mars Science Laboratory. We describe how the detections of Phobos eclipses can be used as an alternative procedure to determine the coordinates of the rover.
