Tethys

Tethys

Tethys is a mid-sized icy moon of Saturn, notable for its large impact crater Odysseus and the massive canyon system Ithaca Chasma. In game, this heavily cratered moon offers moderate habitation potential in the Saturnian system.

Mining Sites

Notes:

• Negative values are not a bug, the game actually sets the median to a negative value to make it incredibly unlikely for the site to have a positive mine output. But note that the actual mined amount cannot actually be negative.
• Blank values indicate that the site can never produce this resource. In contrast, 0 indicates that there is still up to 50% chance for the site to produce the resource.
• Values shown do not take into account the final capping of the Noble Metals output to just 1/2 or 1/3 of the Base Metals output.
• Top 50% Mean is the average value of the top 50% of possible rolls. It is also a much looser estimate than the median because it cannot handle edge cases such as where the mininum value is too close to the median value.

Strategic Value

With 4 habitation sites, Tethys provides a significant presence in Saturn's inner moon system. Its position in Saturn's E-ring makes it valuable for resource extraction operations, while its substantial size supports multiple potential bases.
