Missing Scientists
Locations: Nexus, Eriksson System
Get this quest the first time you speak to Dr. Aridana, in Operations aboard the Nexus.
Her missing scientists can be found in the Eriksson system, once you have access to the Tempest. Scan from system view, and locate the anomaly in the Scourge cloud, up and to the right of the sun.
This is the Eudoxus, the lost vessel. Finding it completes the Task- you do not need to follow up with Aridana
