Listening Post Alpha in the Erebus system is reportedly being attacked by unidentified life forms and is requesting assistance.
Acquisition: You first have to complete Noveria to gain the Styx Theta cluster on your map. When you enter the Erebus system first you will receive a distress signal and this assignment will appear in your journal.
Trivia: This assignment may be a homage to the book/movie Starship Troopers. If this assignment is done after escaping from the Citadel as part of Race Against Time, Shepard will make mention to Lt. Durand of both the Citadel and Fifth Fleets being after the Normandy.
Completing this will give you UNC: Listening Post Theta assignment.
UNC: Depot Sigma-23 - The data you found at Listening Post Theta indicates that a supply ship came from Depot Sigma-23 in the Gorgon system just before the attacks on Listening Posts Alpha and Theta. That supply depot is likely where this rachni infestation originated.
Trivia: Even if you investigate this mission after completing other missions relating to Cerberus, your party may still ask about Cerberus as if they've never heard the name before.
In the Mass Effect 2 assignment N7: Lost Operative, Shepard is tasked with recovering data which could "conclusively prove Cerberus' involvement in rachni experiments" from an Eclipse base.
Joker references Cerberus' failed experiments on the rachni as one of several examples of the organization's incompetence at the party in the Mass Effect 3: Citadel DLC.
Mass Effect is a 2007 action role-playing video game developed by BioWare. Mass Effect is set within the Milky Way galaxy in the year 2183 where interstellar travel is possible through the use of mass transit devices called Mass Relays, a technology believed to have been built by an extinct alien race known as the Protheans. A conglomerate body of governments known as the Citadel Council controls a large percentage of the galaxy and is responsible for maintaining law and order among races of the galactic community. Races that belong to the Citadel Council include humans, asari, salarians, and turians. Other alien races seen in the game include the reptilian krogan, the environmental suited quarians, and a hostile race of networked artificial intelligences called geth. Humanity is represented by the Systems Alliance, an organized body that joined the galactic community in 2157.
