This achievement is story-related and cannot be missed.

After the Hyperwave Relay is built and begins to function as it should (cutscene embellishments to let you know this has happened), you will shoot down and investigate (assault) a medium-sized alien craft, the "Overseer" ship.

After completion of this assault, whether you killed or captured the Ethereal, this achievement will unlock.
