Martian Moons eXploration (MMX) is a robotic space probe set for launch in 2026 to bring back the first samples from Mars' largest moon Phobos. [3] [5] Developed by the Japan Aerospace Exploration Agency and announced on 9 June 2015, MMX will land and collect samples from Phobos once or twice, along with conducting Deimos flyby observations and monitoring Mars's climate.
The Japanese agency's sample return mission will explore the origin of Mars' curious moons.
The motions of Phobos and Deimos would appear very different from that of Earth's Moon. Speedy Phobos rises in the west, sets in the east, and rises again in just eleven hours, while Deimos, being only just outside synchronous orbit, rises as expected in the east but very slowly. Despite its 30-hour orbit, it takes 2.7 days to set in the west ...
Because Phobos orbits close to Mars and in line with its equator, transits of Phobos occur somewhere on Mars on most days of the Martian year. Its orbital inclination is 1.08°, so the latitude of its shadow projected onto the Martian surface shows a seasonal variation, moving from 70.4°S to 70.4°N and back again over the course of a Martian ...
Mars may have had a single moon before something smashed into it, tearing it asunder into the two moons we see today. In a study published Monday in Nature, scientists explained how they used the ...
Phobos, one of the two moons of Mars Parent body, the planet Mars. The top-level science goal is to understand the formation of the Martian moons Phobos and Deimos and put constraints on the evolution of the Solar System (co-formation, capture, impact ejecta).
Phobos (/ ˈ f oʊ b ə s /; systematic designation: Mars I) is the innermost and larger of the two natural satellites of Mars, the other being Deimos. The two moons were discovered in 1877 by American astronomer Asaph Hall. Phobos is named after the Greek god of fear and panic, who is the son of Ares (Mars) and twin brother of Deimos.
