Travel the cluster and take planetary scans to improve Dr. Aridana's celestial model.
Speak to Dr. Aridana again after getting Task: Missing Scientists and agree to help her to accept the task.
Access the Terminal Edit
Interact with the nearby terminal to get an update on her cluster model.
Scan Planets Across Heleus Edit
Ryder will have to scan 50 planets to complete this objective.
Speak with Dr. Aridana Edit
Dr. Aridana is pleased with your efforts, and gives you your reward.
Note: Ryder receives this even though on some occasions no message on screen says so, because it might disappear before you are able to see it. Anyway, after completing the task Ryder has 1330 less XP to the next level than before the conversation with Aridana.
