On reaching the destination planet, the Tripborn refuse to leave the ship. Never having lived on a planet, they don't seem to see the appeal. Additionally the idea causes severe agoraphobia, as experienced by one Tripborn crew member who makes a landing on the planet and must be retrieved by remote control. The Earthborn crew members employ a variety of means to make the Tripborn less comfortable on the ship, such as Psychoactive Drug included in the food supply and subtle background sounds designed to cause unease. However this fails to move the Tripborn, even despite the fact that the ship will be unable to support the full crew's life for more than a few weeks more. The Tripborn also note that it's difficult to accept the Earthborn crew's rosy predictions for the future when the overall mission calls for the Earthborn to return home, leaving the Tripborn to establish the colony.
