The larger of the two satellites of Mars

Nouns denoting natural objects (not man-made)

Context examples:
MAVEN, with an elliptical orbit around Mars, has an orbit that crosses those of other spacecraft and the moon Phobos many times over the course of a year.
(NASA Orbiter Steers Clear of Mars Moon Phobos, NASA)
Phobos has been considered as a possible initial base for human exploration of Mars because its weak gravity makes it easier to land spacecraft, astronauts and supplies.

This is the first collision avoidance maneuver that the MAVEN spacecraft has performed at Mars to steer clear of Phobos.
(NASA Orbiter Steers Clear of Mars Moon Phobos, NASA)
The study shows that this plasma void behind Phobos may create a situation where astronauts and rovers build up significant electric charges.
(Solar Eruptions Could Electrify Martian Moons, NASA)
This creates a void on the night side of Phobos that the plasma flow is obstructed from directly entering.
(Solar Eruptions Could Electrify Martian Moons, NASA)
Powerful solar eruptions could electrically charge areas of the Martian moon Phobos to hundreds of volts, presenting a complex electrical environment that could possibly affect sensitive electronics carried by future robotic explorers, according to a new NASA study.
(Solar Eruptions Could Electrify Martian Moons, NASA)
Although this study focused on Phobos, similar conditions are expected at Deimos, since both moons have no atmosphere and are directly exposed to the solar wind – a stream of electrically conducting gas, called a plasma, that’s constantly blowing off the surface of the Sun into space at around a million miles per hour.
