Ka haere a Watney ki te tiki i te rover e tata ana ki te Pathfinder, i noho puku i te tau 1997. Mā te whakamahi i te kāmera me te pūkaha o te Pathfinder, ka whakapumautia e ia he whakawhitiwhitinga korero-rua ki te whenua, i te tuatahi ma te whakamahi i nga tohu ngawari, ka tuku me te whiwhi ASCII i roto i te hexadecimal. Ka tukuna e NASA he papa rorohiko hei hono i te rover ki te Pathfinder me te whakawhitiwhiti korero ma te kuputuhi. Ka riri a Watney ka mohio ia kaore i korerotia ki te roopu mo tona oranga, a ka tuku a Sanders ki a Henderson kia whakamōhio atu ki a raatau.
i te wā e mōhio ana ia kāore i whakaaturia ki te kaipuke tōna oranga
