In communicating with Earth, Poole and Bowman are directed to disconnect Hal for analysis. Poole and Bowman become suspicious at Hal's refusal to admit that his diagnosis was mistaken Hal then claims that the replacement AE-35 unit will fail. Poole takes one of the extra-vehicular pods and swaps the AE-35 unit but when Bowman conducts tests on the removed AE-35 unit, he determines that there was never anything wrong with it.

While Poole is receiving a birthday message from his family on Earth, Hal tells Bowman that the AE-35 communication unit of the ship is going to malfunction. The HAL 9000, an artificially intelligent computer, addressed as 'Hal', maintains the ship. Frank Poole are the only conscious humans aboard their three colleagues are in suspended animation, to be awakened near Saturn. Ī mission, Discovery One, is sent to Saturn. Visiting TMA-1, Floyd and others arrive just as sunlight falls upon it for the first time since it was uncovered it emits a piercing radio transmission which the scientists determine is directed at one of the moons of Saturn, Japetus (Iapetus). Excavation has revealed a large black slab, precisely fashioned to a ratio of 1:4:9 (or 1 2:2 2:3 2) and therefore believed the work of intelligence. Heywood Floyd travels to the Moon's Clavius Base, where a scientist explains that they have found an electromagnetic disturbance, designated Tycho Magnetic Anomaly One (or TMA-1), in the crater Tycho. They then use the tools to kill a leopard preying on them the next day, the main ape character, Moon-Watcher, uses a club to kill the leader of a rival tribe. The hominids use their tools to kill animals and eat meat, ending their starvation. The book shows one such monolith appearing in prehistoric Africa, three million years ago (in the movie, four mya), where it inspires a starving group of hominids to develop tools. The first part of the novel, in which aliens influence the primitive ancestors of humans, is similar to the plot of Clarke's 1953 short story ' Encounter in the Dawn'.Ī mysterious alien civilization uses a tool with the appearance of a large crystalline monolith to investigate worlds across the galaxy and, if possible, to encourage the development of intelligent life. An elaboration of Clarke and Kubrick's collaborative work on this project was made in the 1972 book The Lost Worlds of 2001. By 1992, the novel had sold three million copies worldwide. The story is based in part on various short stories by Clarke, including ' The Sentinel' (written in 1948 for a BBC competition, but first published in 1951 under the title 'Sentinel of Eternity'). Clarke and Kubrick worked on the book together, but eventually only Clarke ended up as the official author. It was developed concurrently with Stanley Kubrick's film version and published after the release of the film. 2001: A Space Odyssey is a 1968 science fiction novel by British writer Arthur C.
