Map of Altahe.

Altahe

To visit the Acheron system in the Styx Theta cluster you have to complete the mission on Noveria, first. Altahe is an odd planet in that you may not actually have an assignment when you land on it. If not you can start UNC: Listening Post Theta by visiting a Listening Post on Altahe’s surface, otherwise this assignment may start after you complete UNC: Listening Post Alpha in the nearby system of Erebus.

Aside from this, you’ll find some rachni nests in the southeastern corner of the map, which you can clear for some XP.
