Explanation: Why is Phobos so dark? Phobos, the largest and innermost of the two Martian moons, is the darkest moon in the entire Solar System. Its unusual orbit and color indicate that it may be a captured asteroid composed of a mixture of ice and dark rock. The featured assigned-color picture of Phobos near the edge of Mars was captured in late 2021 by ESA's robot spacecraft Mars Express, currently orbiting Mars. Phobos is a heavily cratered and barren moon, with its largest crater located on the far side. From images like this, Phobos has been determined to be covered by perhaps a meter of loose dust. Phobos orbits so close to Mars that from some places it would appear to rise and set twice a day, while from other places it would not be visible at all. Phobos' orbit around Mars is continually decaying -- it will likely break up with pieces crashing to the Martian surface in about 50 million years.

So astronomers can pick a favorite to virtue signal that they are not racists.

Phobos is conserving energy for climate change.

Orbital speed of 4782.5698 miles per hour?
Nice of it to stop for a quick pic before it kept on going - :o

Because NASA has gone WOKE.
In this pic we see ‘mixed race’ Phobos being rejected by ‘white’ Mars/sarc

I can almost see Marvin Martian. I think he has a condo there; on the beach.

If there were a shadow under Phobos in that pic, it would look just like a lava boulder sitting on a Hawaiian beach.

Probably a spacecraft sent by Maxine Waters to find where the astronauts planted the flag before the Ingenuity Mars Helicopter lands and makes the planet tip over.

To get to the other side? To prove to the armadillos that it can be done.

Get ready for Phobos to demand reparations from Deimos!

#2 I saw an image like that on ‘Stargate Atlantis’ tv show where some aliens built a hidden base in their small moon. A deranged alien fired the rockets on a spacecraft parked inside and changed the orbit causing it to hit the atmosphere and breakup.
