Once you have built your Railjack and have done the initial quest after climbing onboard, you are free to start doing Railjack missions.

In these missions you can obtain more parts and resources for upgrading your Railjack and explore the different Proxima that are available.

Each of the Proxima have different difficulties and the harder the missions are, the better the rewards.

You begin first at the Earth Proxima and will need to finish each node in order to unlock the next one and so forth until you unlock the next Proxima.

During each mission, there will be a number of Fighters which are smaller enemy vessels and a number of Crew Ships which you need to destroy in order to complete each mission.

Some missions will have bonus objectives that require you to exit your ship and enter Grineer ships or facilities.

Earth Proxima

The Earth Proxima is the first and easiest Proxima you can do Railjack missions in and will usually reward you with Tier 1 components and weapons.

There is no Intrinsics requirement to do missions in the Earth Proxima and you need only complete each node to unlock the one that comes after it.

Completing all the nodes in Earth Proxima will unlock the Saturn Proxima.
