Phobos

The Grineer have occupied the abandoned settlements here.

—In-game description

Phobos is a moon under Grineer control.

The Phobos Nav Segment can be obtained by defeating General Sargas Ruk, located on Tethys, Saturn.

The Assassination Targets for Phobos are Lieutenant Lech Kril and Captain Vor, located in the mission Iliad. These bosses drop the blueprints for the Miter and its components, the Twin Gremlins, and the components for the Trinity Warframe. They also both have a higher than average chance to drop Morphics.

Phobos & Mars are the only planets to feature the Grineer Settlement Tileset.

Phobos does not currently have a Tenno Relay.

Notes

An immense object can be seen above the clouds in space; the object appears to be a Grineer Asteroid base and possibly Mars' other moon Deimos. This is quite remarkable for how large the object is seen in space, perhaps making it the largest Grineer mining operation to date.
Although the Grineer have supposedly occupied the moon recently (one of their most recent occupations at any rate) there are signs of very old Grineer equipment scattered and rusting in some places, perhaps suggesting that the Grineer were previously here before but had to evacuate at some point.
- The planet is littered with massive wind generators, providing what appears to be the majority of the planet's power, and various pumps and water bays are used to filter and process water.
Barring Fieldron Samples, Phobos shares its resources with Pluto.

Tips

Phobos contains high drop rates of both Rubedo and Morphics.
Due to the level of Iliad, Vor is significantly more powerful on Phobos than he is on Mercury, but Kril is weaker than he is on Ceres.
- Vor is however still weaker than his Corrupted version.
Sentinels have a very slim chance of surviving during these levels as constant bombardments from Hellions can easily destroy them regardless of how durable they may be.

Bugs

During the cinematic of Captain Vor and Lieutenant Lech Kril on Iliad, some players' screens may go black and they won't be able to see what is happening.
Kril will often spawn partially inside the large spherical object on the top of the arena area, immobilizing him for the majority of the battle.

Trivia

Phobos is named after the Greek personification of fear and one of the sons of Ares, who is Mars' Greek equivalent. It has a twin moon called Deimos (strife), the latter currently is not available in Warframe and there are no plans on adding it.
- In contrast to how Phobos is depicted in-game, in real life, it is irregular in shape. It is widely believed to be a captured asteroid.
- The nodes on Phobos are named after actual named geological features of Phobos. Other than Monolith and Iliad, those in turn are named either after astronomers (e.g. Asaph Hall, who discovered Phobos) or after characters in Gulliver's Travels (as its author, Jonathan Swift, predicted the existence of Mars' moons).
- The boss level, Iliad, is named after an ancient Greek epic poem, which tells of the battles and events during the weeks quarrel between the King Agamemnon and the Warrior Achilles.
This planet was unlocked as a reward for the community completing the Arid Fear Event. Much of the event involved the Grineer and the Corpus trying to hide Phobos' existence from the Tenno.
Up until The Gradivus Dilemma Phobos was the third planet in the game that was completely under the control of a given faction (besides the indigenous species), following the (then) Infested-controlled planets of Eris and Jupiter.
Phobos is the first planet to have an Assassination mission involving more than one entity, the second being the first phase of Lephantis.
Looking into the distance from the extraction point, one will be able to see what looks like a Fomorian ship on its side in the far background.
Phobos' geology appears to resemble Mars in reality, having a reddish appearance to the soil and a desert like environment.
Phobos is the only planet in which Research components do not drop.
There are three Kuria statues hidden throughout the Grineer Settlement tileset.
