Phobos 360

NASA APOD
COSMIC MESSAGE

Phobos is one of Mars's two moons. This composite image from ESA's Mars Express orbiter shows its irregular shape, dark surface, and many craters and grooves. Phobos is tidally locked, meaning it always shows the same face to Mars, just like Earth's Moon. What lies beneath its surface is still a topic of ongoing research.
