Phobos photometric properties from Mars Express HRSC observations [PDF]

Astronomy & Astrophysics
This study aims to analyze Phobos' photometric properties using Mars Express mission observations to support the Martian Moons eXploration mission (MMX) devoted to the investigation of the Martian system and to the return of Phobos samples.

Trajectory Design of Perseus: A CubeSat Mission Concept to Phobos

Aerospace, 2020
The Martian satellites Phobos and Deimos hold many unanswered questions that may provide clues to the origin of Mars. These moons are low Δv stopover sites to Mars.

MMX geodesy investigations: science requirements and observation strategy

Earth, Planets and Space, 2021
In order to investigate the origin of Phobos and Deimos, the Japanese Martian Moons eXploration (MMX) mission is scheduled for launch in 2024. MMX will make comprehensive remote-sensing measurements of both moons and return regolith samples from Phobos ...

Human exploration of Phobos [PDF]

2015 IEEE Aerospace Conference, 2015
This study developed, analyzed, and compared mission architectures for human exploration of Mars' moons within the context of an Evolvable Mars Campaign. METHODS: All trades assumed conjunction class missions to Phobos (approximately 500 days in Mars system) as it was considered the driving case for the transportation architecture.

Spacecraft exploration of Phobos and Deimos

Planetary and Space Science, 2014
AbstractWe 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 formed the basis for early Phobos and Deimos shape and dynamic models.

Lessons from PHOBOS [PDF]

Nuclear Physics A, 2009
In June 2005 the PHOBOS Collaboration completed data taking at RHIC. In five years of operation PHOBOS recorded information for Au+Au at $\sqrt{s_{NN}}$ = 19.6, 62.4, 130, and 200 GeV, Cu+Cu at 22.4, 62.4 and 200 GeV, d+Au at 201 GeV, and p+p at 200 and 410 GeV, altogether more than one billion collisions.

The Mars system revealed by the Martian Moons eXploration mission

Earth, 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 ...
