Outer Wilds Wiki

The Attlerock is the only natural satellite of Timber Hearth. It is almost entirely barren, the terrain mostly level except where it is pocked with deep craters. There are a few large craters with pieces of information in them, and the first Eye Signal Locator you will find in the game, along with being the first mention of the Eye of the Universe in Nomai texts.


Lunar Outpost[]

The Lunar Outpost is where Esker lives, a small forested camp that used to serve as a pit-stop for Hearthians making their first space flight, in their space program's more turbulent days. Within the outpost resides Esker themself at their wooden lodge, a campfire where you can roast marshmallows, and trees to refill your oxygen supply.

Esker offers a few conversations, and admits to sometimes shooting little scouts at the village to feel less lonely. Within the outpost you'll also find three wooden platforms, the last of which contains Esker's notes on the various spacefaring Hearthian's instruments, this will help point you towards Riebeck and Feldspar.

Lunar Lookout[]

The Lunar Lookout is located at the Attlerock's north pole, not far from the Lunar Outpost. It consists of a set of platforms set in the north pole crater, the last of which has a lamp and a notepad. This is where Esker used their signalscope to monitor the solar system, track the other travelers, and even spy on conversations down on Timber Hearth.

Eye Signal Locator[]

The Attlerock is home to the first, and most simple Eye Signal Locator, a large device the Nomai attempted to use to pinpoint the location of the Eye of the Universe. While the Locator is largely in ruins, it can still be operated. The Locator has four different settings, set to locate the Sun, Giant's Deep, Brittle Hollow, or the Eye of the Universe. Using the former three settings, the outer rings will successfully align with the Sun, Giant's Deep, or Brittle Hollow, and allow you to listen to their respective signals. However, if the Locator is set to align with the Eye of the Universe, it will rotate randomly and never settle on a location.

On the lower level, some Nomai writing may be found providing directions to the second Eye Signal Locator, at the Southern Observatory on Brittle Hollow.

Large Impact Crater[]

There is a large impact crater on the dark side of the Attlerock, dotted with large shards of otherworldly ice. Within the crater itself near a shard can be found a lantern and some Hearthian tools, along with a recording from Chert.

The recording states Chert's hypothesis that a fifth ice planet used to exist in the solar system, before dramatically imploding due to the expansive growth of an infectious seed, becoming what is now known as Dark Bramble. They believe the crater was formed from a piece of the former planet, sent hurtling off upon Dark Bramble's implosion, crashing into the Attlerock, leaving residual chunks of ice. Chert also hypothesises that similar ice shards may be found throughout the solar system.


Texts and recordings[]


  • It is possible to use only the spacesuit to fly to the moon from Timber Hearth, then fly back to the surface of Timber Hearth.
  • There is an achievement that can be unlocked by launching Mica's model rocket, and successfully landing it on the Attlerock.
