There are two ways to get this quest from Captain Klork: 1) If you have not taken a quest from Captain Klork before, this will be the first misson he gives you. 2) If you have done this quest before, when you speak to Captain Klork, chose the option that says, "I was hoping to hack some more sensor arrays?" The Empire has set up sensor arrays around Restuss to help their search for research data. The Alliance wants to capture one of these so that they can use them for the same thing.
