GETEMME: a mission to explore the martian satellites

open access: yes, 2011
GETEMME (Gravity, Einstein's Theory, and Exploration of the Martian Moons' Environment) is a proposition of mission towards martian's moons. The spacecraft will initially rendezvous with Phobos and Deimos in order to carry out a comprehensive mapping and characterization of the two satellites and to deploy passive laser retro-reflectors on their ...

A new reduction of USNO photographic plates of the Martian satellites

open access: yes, 2012
Thanks to the new technologies, a new astrometric reduction of old photographic plates can provide a better knowledge of the orbital motion of planetary satellites. In the cadre of the FP7 european project, USNO plates were digitized with the new generation DAMIAN scanning machine.

REMOTE SENSING OBSERVATIONS AND NUMERICAL SIMULATION FOR MARTIAN LAYERED EJECTA CRATERS [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2018
To understand past Martian climates, it is important to know the distribution and nature of water ice on Mars. Impact craters are widely used ubiquitous indicators for the presence of subsurface water or ice on Mars.

Retrospective Review of a Two-Phase Mechanically Pumped Loop for Spacecraft Thermal Control Systems [PDF]

open access: yesJournal of Mechanical Engineering, 2021
The main issues associated with the development of two-phase mechanically pumped loops (2-MPL) for thermal control systems of spacecraft with large heat dissipation were formulated back in the early 80s. They have undeniable advantages over single-phase

The Mars system revealed by the Martian Moons eXploration mission

open access: yesEarth, Planets and Space, 2022
Japan Aerospace Exploration Agency (JAXA) plans a Phobos sample return mission (MMX: Martian Moons eXploration). In this study, we review the related works on the past climate of Mars, its evolution, and the present climate and weather to describe the ...

Interplanetary Magnetic Field Effect on the Location of the Martian Bow Shock: MAVEN Observations

open access: yesThe Astrophysical Journal, 2023
The Martian bow shock (BS) is generated with the mass-loading and magnetic pileup processes when the solar wind interacts with the Martian ionosphere. In this vein, the interplanetary magnetic field (IMF) frozen in the solar wind can affect the location ...

SegMarsViT: Lightweight Mars Terrain Segmentation Network for Autonomous Driving in Planetary Exploration

open access: yesRemote Sensing, 2022
Planetary rover systems need to perform terrain segmentation to identify feasible driving areas and surround obstacles, which falls into the research area of semantic segmentation.

Low-Thrust Transfer to Quasi-Synchronous Martian Elliptic Orbit via Nonlinear Feedback Control

open access: yesAerospace, 2023
This study considers the problem of injecting a spacecraft into an elliptic, repeating-ground-track orbit about Mars, starting from a 4-sol highly elliptical orbit, which is a typical Martian capture orbit, entered at the end of the interplanetary ...

Oxygen Isotopes and Volatiles in Martian Meteorite [PDF]

open access: yes, 2013
Oxygen isotopes were measured in mineral separates from martian meteorites using laser fluorination and were found to be remarkably uniform in both δ18O and Δ17O, suggesting that martian magmas did not assimilate aqueously altered crust regardless of any

Dusty plasmas at Martian satellites

open access: yesJournal of Physics: Conference Series, 2019
Dusty plasmas are shown to be formed in a surface layer over the illuminated part of Martian satellites Phobos and Deimos owing to photoelectric and electrostatic processes. The distribution functions of photoelectrons near surfaces of the satellites, altitude dependences of the density of dust particles, and their charges and sizes, as well as ...
