In Wuthering Waves, the Spacetrek Observatory quests are a set of three Exploration Quests that let you rebuild the observatory and unlock the Weather Simulation feature. These quests are tied to the Lahai‑Roi Reconstruction Project, where you help restore routes and infrastructure in the region.
Spacetrek Observatory: How to Start & Location
The three observatory quests are part of the Lahai‑Roi Reconstruction Project, so you first need to complete several route‑rebuild quests nearby. Once those are done, you can begin the observatory phases in order.
Make sure you’ve completed the following route quests in Lahai‑Roi:
- Rebuild Farer’s Road
- Rebuild Submerged Tunnel
- Rebuild Sandreach Passage
- Rebuild Starleap Ascent (Route Constructor)
- Rebuild Howling Tunnel (unlocks Urban Legend: Lost in the Fog Tunnel)
Once you’re done, head to the Spacetrek Observatory and follow the quest marker for Spacetrek Observatory Foundation Phase, then speak with Rakosan to begin the first phase.
