Phobos

The information I have suggests that Deimos and Phobos look somewhat similar to Earth’s moon, though they are much smaller in size.

The spacecraft will spend three years around Mars conducting science operations to observe Phobos and Deimos.

A second liquid layer inside the planet also meshes better with other evidence, such as how Mars responds to being deformed by the gravitational tug of its moon Phobos.

Many industry experts note that even before the latest Western sanctions, the use of substandard components led to the collapse of an ambitious mission to send a probe to Mars’ moon Phobos in 2011.

MMX will land on Phobos in two locations and spend two hours on the surface collecting about 10 grams of material in total.
