Rotation period is the time required for a body to rotate about its axis. The lower the rotation period, the greater the rotation boost. Also, the lower the rotation period, the lower the effective surface gravity at the equator and the more disk shaped the planet becomes. The rotation period for mars is from Physical Solar System Data and the sideral rotation period for the moon is from Solar System Data. Rotation period is used with latitude and radius to calculate rotation boost.

rotation boost = 2 * pi * cos( latitude ) * radius * rotation period
 

This is used in atmospheric spacecraft, multi stage spacecraft, and spacecraft cost.
