Taken Assault: Earth
The first step in The Taken War: Petra tasks you with killing Champions in the Divide, Skywatch, and Rocketyard in the Cosmodrome. To kill these Champions, you will first have to kill three Lieutenants that spawn randomly in the vicinity. When they are dead you can expect the Champion to arrive.
It is advised that you bring a Fireteam with you, these Champions are extremely tough to kill.
You will also need to find some items from killed Taken and Fallen enemies.
Taken Assault: Venus
Much like the previous step, you will need to kill Champions, but the location is now Venus. The Champions can be found in the Shattered Coast, Ishtar Cliffs, Ishtar Commons, and the Citadel. Kill the three Lieutenants to summon the Champion, ideally bringing your Fireteam along for the ride.
Taken Assault: Mars
You will need to kill more Champions, but this time on Mars. You can find the Champions in the Barrens, Scablands, Hollows, Buried City, Valley of the Kings, and Rubicon Wastes. You will need to kill the three Lieutenants to summon the Champion.

Hunt the Archon
Mars is where you'll find the Archon, specifically in the Rubicon Wastes. To find the Rubicon Wastes, head to the right from patrol spawn and into the Scablands, then turn right and head under the bridge, following the winding path into Firebase Rubicon. Pass through the base and into a tunnel system which will end with you entering Rubicon Wastes.
A Fallen Skiff randomly delivers a platoon of Fallen into the Rubicon Wastes, followed by the Archon you must kill.
A New Den
Complete the Mars mission, A New Den. This mission sees you fighting backward through the Cerberus Vae 3 Strike and holding out against countless waves of Fallen.
You will need to complete the Mars mission, Knock Knock in order to progress the questline. You will fight your way around Mars fighting both Cabal and Fallen with the mission culminating in a Walker tank fight.
The final Mars mission in this questline is to hunt down a new Servitor that has risen on Mars.
