You may be looking for Duty Officer Assignment Node instead.

Previously, an Exploration Cluster was a Sector where various random Exploration missions, and Anomalies could be found.


In an Exploration Cluster you will find the various Exploration missions. While in Federation Space only one Cluster is attached to each Sector Block you will find all Klingon Clusters are attached to the Omega Leonis Sector Block.

Upon entering a cluster you will see the vastness of space, with little red anomaly dots showing up. When you get near them you get one of two options, either you found an anomaly that will trigger the Scanning Minigame or that let's you enter a random system to explore.

Genesis Engine[]

The Genesis Engine was built by Cryptic Studios. The Engine was intended to effectively create new mission quickly for the game developers via the exploration clusters.

New planets were randomly generated during development, meaning, that the Genesis Engine was not part of the server or client software and that missions are not created during runtime. Instead, the missions created by the Engine have to be manually reviewed by a developer before they are added to the game. Currently, there are more than 3775 such pre-rendered missions in the game as exploration content in star clusters.


  • All Clusters share the same basic layout, only the orientation differs from Cluster to Cluster.
  • While the exploration missions seem random at first glance, they are not random at all. They are pulled from a huge pool of predefined missions. So after a while you may get a mission you have already done.
  • Removed from game as part of the Season 9.5 update patch on 17 July 2014, and replaced with new nodes, offering Duty Officer assignments only.
