There are many secrets lurking in the Mass Effect universe. Completing them earns money, gear, and experience for Shepard. Among these objectives, you must help a Salarian, Chorban, to scan the Watchers, strange insectoid creatures inhabiting the Citadel. Some spoilers are present in the solutions.
Location of the Watchers
This quest can be obtained from the start of the game, after the meeting with the Council is over. Just walk towards Churban in the center of the room and accept his request.
