Land on Eos and investigate the first datapad to acquire the task.
To complete this task, you must recover three of the associated datapads located at different Remnant sites. The sites include a station located near the forward station south of Resilience, a Scourge-infested Remnant site south of the monolith lake, and one near the kett base in the mountains.
Once all three datapads are collected, a Nav-point will be set to an underground Remnant facility. Take the gravity well down to see the conclusion of the researcher Ana Carrell.
Deeper into the site there is a Remnant Destroyer which Ana successfully activated, once destroyed, Ryder can freely scan and collect loot that resides in the room.
