on arrival at lunarville 7, the officers are met by the controller and his assistant, orson. they are also introduced to the colony's main computer, an artificial intelligence called "speech intelligence decoder" (sid) that identifies humans through recognition discs. after the officers hand over the president's letter, orson agrees to take them on a trip in a moonmobile, a vehicle that exploits the moon's low gravity to jump and glide over its surface. however, when scarlet suggests a visit to the humboldt sea, orson angrily refuses and returns them to lunarville 7. while retiring for the night, the officers find that their accommodation has been bugged.
