The image resolution is 110 m/pixel for Phobos and 240 m/pixel for Deimos — Deimos was more than ... was made possible by the unique elliptical orbit of Mars Express, precise knowledge of ...

There's not much hustle and bustle on Mars. The red planet is inhabited by no-one that we know of, except the robotic rovers ...

Although the orbit of the inner moon, Phobos, has been calculated to an accuracy of less than 0.6 mile (1 kilometer), the path of more remote Deimos is less well-known. In order to improve the ...

As a result, an astronaut on Mars would see Phobos rising in the west and setting in the east. Deimos orbits Mars at an altitude of approximately 23,500 kilometres and has an orbital period of just ...

Phobos and Deimos. Neither is anything like Earth's moon: small and irregularly shaped, astronomers have long believed that they are more likely captured asteroids, pulled into the Martian orbit ...

However, captured bodies usually end up in eccentric, inclined and often retrograde orbits, whereas Phobos and Deimos orbit Mars in the red planet's equatorial plane and in prograde fashion.

Though little is known about Deimos, another European spacecraft recently captured unprecedented views of the moon's far side ...

Even the Martian moons Phobos and Deimos are petite, measuring just a few kilometers in diameter. Scientists aren't even sure ...

and Deimos is 15 km across. Phobos is also the closer of the two to Mars. It orbits just 6,000 km above the surface and completes an orbit every seven hours and 39 minutes. Deimos, at more than ...
