History of telescopic observations of the Martian satellites

Planetary and Space Science, 2014
Abstract This article intends to review the different studies of the Mars satellites Phobos and Deimos realized by means of ground-based telescopic observations as well in the astrometry and dynamics domain as in the physical one. This study spans the first period of investigations of the Martian satellites since their discovery in 1877 through the ...

Martian satellite orbits and ephemerides

Planetary and Space Science, 2014
Abstract We discuss the general characteristics of the orbits of the Martian satellites, Phobos and Deimos. We provide a concise review of the various descriptions of the orbits by both analytical theories and direct numerical integrations of their equations of motion.

On the orbital evolution of the Martian satellites

Journal of Geophysical Research, 1979
The tidal evolution of the Martian satellites has been investigated, and it is found that tides raised by the planet on the satellite can have significant consequences if the rigidity of the satellites is much less than the average rigidity of Mars. This would be the case if the satellites have a carbonaceous chondritic composition. Frequency dependent

Orbital history of the Martian satellites with inferences on their origin

Icarus, 1980
Abstract Recent Viking results indicate the Martian satellites are composed of carbonaceous chondritic material, suggesting that Phobos and Deimos were once asteroids captured by Mars. On the other hand, the low eccentricities and inclinations of their orbits on the equator of Mars argue against that hypothesis.

Numerical Simulation of the Motion of Martian Satellites

2001
The numerical long-term prediction of the satellite motion is very laborious. This is mainly because the high rate of the change of the right member functions of the classical equation of motion results in a small step in numerical integration and, in turn, in a rapid accumulation of the round-off errors.

Orbital evolution and origin of the Martian satellites

Icarus, 1983
Abstract The role of tidal dissipation within the Martian satellite system is examined through orbital evolution integrations and assessed in the context of its origin scenario through calculations of collision probabilities between Phobos and Deimos in the distant past.

The motion of the Martian satellites

Celestial Mechanics, 1975
An extensive analysis of the motion of Phobos and Deimos from 1877 to 1973 has been fulfilled. The new values of the parameters of the orbital model first developed by Struve have been determined for both satellites. The new sets of the orbital parameters compete with the solutions of similar accuracy found by Wilkins and Sinclair.

A Comparative Analysis and Study on Martian Satellites

International Journal of Engineering Trends and Technology, 2014
The use of satellites in communication systems is very much a fact of everyday life, as is evidenced by the many homes equipped with antennas or dishes used for the reception of satellite television. Satellites offer a number of features not readily available with other means of communication.

Dusty Plasma near the Martian Satellite Deimos

Plasma Physics Reports, 2018
The formation of dusty plasma in the near-surface layer above the illuminated part of the Deimos, the satellite of Mars, due to photoelectric and electrostatic processes is analyzed. Using a physicomathematical model self-consistently describing the densities of photoelectrons and dust grains above the illuminated part of Deimos, the distribution ...
