Horizon Lunar Colony
"Susan" was the name given to one of the chimp test subjects at the Horizon Lunar Colony. Her official designation was Specimen 20.
Years after the apes of Horizon took over the base, Lucheng Interstellar was able to retrieve information from Horizon's still-operating monitoring system. Susan was noted to still be in the colony.
