Phobos

Phobos

Phobos is the larger and innermost of Mars' two moons. It orbits extremely close to Mars, completing an orbit in less than 8 hours. Its small size and irregular shape suggest it may be a captured asteroid. The game features 1 habitation site on Phobos.

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

Phobos' proximity to Mars makes it a useful staging location for operations on the Martian surface. Its low gravity well makes it an efficient, defensible shipbuilding site.
