Mars

Mars is a planet under Grineer control, with skirmishes and several Crossfire missions with the Corpus.

Mars becomes accessible by defeating the Specter in the Mars Junction on Earth after completing the required tasks.

The Assassination Target for Mars is Lieutenant Lech Kril, located in the mission War. Components for the Frost Warframe can be obtained after completing the boss battle.

Mars is the only planet to feature the Grineer Settlement Tileset as its primary environment.

Mars was originally inhabited by a civilization that worshiped the golden 'Skymen'. The Grineer eventually invaded the planet and exterminated the entire population, with the exception of Baro Ki'Teer. It is also the possible origin of the Inaros Warframe.

Mars does not currently have a Tenno Relay.

Enemies
Invasion Missions: The Infested will always appear as an "Opposing" faction during Invasion missions. Spy Missions: Special enemy variants have a chance of spawning during Spy missions. Survival Missions: The following lists below do not apply to Survival missions.

Tips

 * Lieutenant Lech Kril can drop Gallium in quantities of up to two.
 * During Crossfire missions, both the Corpus and the Grineer will activate the opposing faction's security systems.
 * Mars is the best Planet to farm Salvage, due to the fact that Salvage is the only non-rare Resource on the planet.

Trivia

 * Mars is named after the Roman God of war; both the god and planet are associated with war and death.
 * Most of Mars's mission nodes are named after geographical locations on Mars.
 * Ultor is an exception; it is instead named after one of Mars' epithets, Mars Ultor ("Mars the Avenger" in Latin).
 * Kadesh is also an exception, named after a battle between Egypt's Ramses II and the Hittite empire.
 * The fact that both the Corpus and the Grineer are present on Mars is a nod to The Gradivus Dilemma, which ended with the Grineer taking over several nodes originally controlled by the Corpus. This makes Mars the first planet where all three major enemy factions are present.
 * Mars was a purely Corpus-controlled planet from until, when several nodes were given to the Grineer.
 * When originally released, Mars had the snowy Corpus Outpost tileset as its environment, which did not reflect the red, sandy environment that Mars has. This was fixed in, with the Grineer Settlement tileset replacing Corpus Outpost as the main planetary tileset to better reflect Mars' appearance.
 * Due to an additional change in the Specters of the Rail update, Fieldron samples drop on this planet, even though the Grineer control almost all the nodes on the planet. Whether this is an inconsistent error, or a nod to the fact that the Corpus used to completely control Mars, is unknown.
