Satellite orbit perturbations in a dusty Martian atmosphere

Acta Astronautica, 2012
Abstract In this paper we calculate the effect of atmospheric dust on the orbital elements of a satellite. Dust storms that originate in the Martian surface may evolve into global storms in the atmosphere that can last for months can affect low orbiter and lander missions.

Testing general relativity with Landers on the Martian satellite Phobos

Advances in Space Research, 1989
A planned experiment to obtain range and Doppler data with the Phobos 2 Lander on the surface of the Martian satellite Phobos is described. With the successful insertion on January 29, 1989 of Phobos 2 into Mars orbit, it is anticipated that the Lander will be placed on the surface of Phobos in April 1989.

Models for the Origin of the Current Martian Satellites

2020
The origin of the two small prograde natural satellites of Mars may, or may not, be important in deciphering the early history of planet Mars. There have been many proposals for the origin of Phobos and Deimos but there is no generally accepted model for their origin.

An analysis of Martian satellite photographic observations of 1967

Icarus, 1975
Abstract Photographic observations of the Martian satellites were made at the opposition of 1967 with the Naval Observatory's 61-inch astrometric reflector. A small partially transparent metallic film filter was used to diminish the light from Mars in order that a measurable image for the planetary disk as well as for the satellites could be obtained.

Localization of Lunar and Martian rovers without satellite support

2012 19th International Conference on Microwaves, Radar & Wireless Communications, 2012
This paper presents a method for localization of rovers and probes on different celestial bodies. There are no technical possibilities of running a GNSS-like (Global Navigation Satellite System) system on them. The localization is a crucial condition of proper directing the rover to destination of interest and providing relevant scientific data.

GETEMME – A Mission to Explore the Martian Satellites and the Limits of Solar System Physics

2011
We propose a mission to Mars and its satellites Phobos and Deimos, within the ESA COSMIC VISION program. A spacecraft (S/C) shall deploy retroreflectors on each satellite. These reflectors will act as targets for laser ranging from a Martian orbit for a wide range of science applications in Solar System Dynamics and Fundamental Physics.
