Among the Stars

 is a Fallout 3 quest and achievement in the Mothership Zeta add-on.

Walkthrough
Upon the beginning of this quest you are tasked with destroying three different modules on the ship, all in different sections of the ship, which are the Hangar, Robot Assembly and the Cryo Labs.

Before you venture into each section, you have the option of bringing one of the three specific captives that you unfroze with you to assist in destroying the modules. However, each NPC can only be brought to one predefined sector (like how Paulson can only assist you with the Hangar).
