UAC Mars Base is a UAC facility located on Mars. It is mentioned in Doom, Doom 2, and Doom 64 Remaster.

Background

Doom/Ultimate Doom

Mars Base is the home of some of UAC's radioactive waste facilities. The Marine was stationed there for three years before being deployed to Phobos, where it's invaded by Demons.

Doom 2

The Mars base is soon fell under attack where every human being were killed except the Marine, who single-handedly stopped the invasion.

Back at last. After days of hard fighting in space, you've returned home on well-earned leave. You're one of Earth's crack soldiers, hard-bitten, tough, and heavily-armed. When the alien invasion struck Mars, you were the first on the scene. By killing, killing, and killing, you won. You stopped the invasion, saved Mars base, and became a war hero. What they don't talk about so much is that you were the only survivor. But that's all behind you now. You've quit the military, and are heading home. Your drop pod lands with a crunch. You open 'er up and look out. Damn! The city ahead is on fire. What the devil is going on? You stagger forward, clutching at your sidearm. Packs of refugees are fleeing the flaming metropolis. A band of them shriek in terror. You squint. What's that? Someone is attacking the refugees. You rush up and blast away, killing the troublemaker. It looks like a human but something's wrong. His mouth is filled with half-chewed flesh, and he's all messed up, like a zombie from a bad horror movie. Hell, not again! You can feel it. It's all starting again, just like on Mars. First, people are taken over, turned into cannibal Things. Then the real horror starts, the deformed monstrosities from Outside. But now it's on Earth!

Situation Analysis:

After days of fighting in space, you've returned to Earth only to find the situation is no better than it was on Mars. In fact, it's worse. The hell-spawned hordes are everywhere. Billions are dead. The few remaining survivors have planned to travel into space and save what's left of the human race. Unfortunately, the Earth's only transport has been taken over by flesh-eating mutants. You have to go back in action. Otherwise, humanity is history.

Doom (SNES/PSX)

An image showing Mars reveals that a large section of the planet has apparently been colonized.

Doom 64 Remaster

The Doom 64 Remaster Story mentions Mars base (similar to the Doom II manual and original doom manual):

Years have passed since you stopped Hell’s invasion of Earth. Quarantined for humanity’s safety, the UAC research facilities on Mars were abandoned and forgotten...until now. A signal from a degraded satellite suggests a single entity remains, and it has the power to resurrect the demons. As the only surviving marine who fought Hell’s forces, you are sent on a lone crusade to hunt down the Mother of Demons and stop a renewed demonic invasion.

Note: The original N64 game was set on Phobos and was more of a sequel to ending of SNES Doom (see Doom 64 timeline and Doom 64: The Story So Far (N64)).

Behind the scenes

The manual for Doom II tells of a completely different set of events than occur in both the endings of the original Doom or Ultimate Doom which took place on Phobos and Deimos instead, and lead to the Marine in those games teleporting to Earth through gateways.

Some Fanon believe this to mean that the marines in Doom 1 and Doom 2 are completely different individuals who reached Earth by different means (Mars hero by drop ship, and the Phobos/Deimos marine by teleportation). With one hero having battled on mars and the other battled through Phobos and Deimos instead.

To add to the confusion some of the later manuals and websites also suggest that the marines in Doom 1, 2, 3 (and sometimes those of Resurrection of Evil and The Lost Mission) are the same character. At the very least most sources indicate that the marine from Doom and Doom 3 are the same.

It is possible that after arriving on Earth, the marine was sent back to Mars. This would likely mean that Thy Flesh Consumed took place after his return to Earth on the Dropship and before Doom II started, rather than right after Inferno. If the marine from Doom 3 is the same as well, than it's possible that Doom 3 is actually telling the story of the marine's return to Mars post inferno.

Who knows we but the differences in these characters might have inspired characters such as Doom (character) and Phobos (character), B.J. Blazkowicz III and Stan Blazkowicz as separate characters in Quake and Doom RPG respectively.
