After Frank is killed while attempting to repair the communications antenna he is pulled away into deep space using the safety tether which is still attached to both the pod and Frank Poole's spacesuit. In the novel, the orders to disconnect HAL come from Dave and Frank's superiors on Earth. He fabricates the failure of the AE-35 antenna-steering unit so that their deaths would appear accidental. Mission Control did not want the crew of Discovery to have their thinking compromised by the knowledge that alien contact was already real.) With the crew dead, HAL reasons, he would not need to lie to them. In every person tested, a deep-seated xenophobia was revealed, which was unknowingly replicated in HAL's constructed personality. (This withholding is considered essential after the findings of a psychological experiment, "Project BARSOOM", where humans were made to believe that there had been alien contact. The novel explains that HAL is unable to resolve a conflict between his general mission to relay information accurately, and orders specific to the mission requiring that he withhold from Bowman and Poole the true purpose of the mission.

Bowman jumps across empty space, reenters Discovery, and quickly repressurizes the airlock. Dave circumvents HAL's control, entering the ship by manually opening an emergency airlock with his service pod's clamps, detaching the pod door via its explosive bolts. When Bowman uses another pod to attempt to rescue Poole, HAL locks him out of the ship, then disconnects the life support systems of the other hibernating crew members. HAL uses one of the Discovery's EVA pods to kill Poole while he is repairing the ship. Faced with the prospect of disconnection, HAL decides to kill the astronauts in order to protect and continue its programmed directives, and to conceal its malfunction from Earth. They attempt to conceal what they are saying, but are unaware that HAL can read their lips. In the film, astronauts David Bowman and Frank Poole consider disconnecting HAL's cognitive circuits when he appears to be mistaken in reporting the presence of a fault in the spacecraft's communications antenna. In the aforementioned game of chess HAL makes minor and undetected mistakes in his analysis, a possible foreshadowing to HAL's malfunctioning. The sequence of events and manner in which HAL is shut down differs between the novel and film versions of the story. However, as time progresses, HAL begins to malfunction in subtle ways and, as a result, the decision is made to shut down HAL in order to prevent more serious malfunctions. In the film the artificial intelligence is shown to triumph easily. As a recreational activity, Frank Poole plays against HAL in a game of chess. In 2001: A Space Odyssey, HAL is initially considered a dependable member of the crew, maintaining ship functions and engaging genially with its human crew-mates on an equal footing. The film says this occurred in 1992, while the book gives 1997 as HAL's birth year. HAL became operational in Urbana, Illinois, at the HAL Plant (the University of Illinois' Coordinated Science Laboratory, where the ILLIAC computers were built). 1.3 2061: Odyssey Three and 3001: The Final Odyssey.In addition to maintaining the Discovery One spacecraft systems during the interplanetary mission to Jupiter (or Saturn in the original novel, published shortly after the release of the film), HAL is capable of speech, speech recognition, facial recognition, natural language processing, lip reading, art appreciation, interpreting and reproducing emotional behaviours, automated reasoning, and playing chess. In the context of the series, HAL became operational on 12 January 1999 at the HAL Laboratories in Urbana, Illinois as production number 3 in the film 2001, the activation year was 19 in earlier screenplays. HAL speaks in a soft, calm voice and a conversational manner, in contrast to the crewmen, David Bowman and Frank Poole, who speak tersely and with little emotional inflection.

#Hal 9000 singing series
HAL 9000 is voiced by Douglas Rain in the two film adaptations of the Space Odyssey series & a short film voiced by Andrew Stanton. HAL's exterior physical form is not depicted, though it is visually represented as a red television camera eye located on equipment panels throughout the ship, and its interior in the scene where his advanced memory modules are disconnected. The primary antagonist of 2001: A Space Odyssey, HAL ( Heuristically programmed ALgorithmic computer) is a sentient computer (or artificial general intelligence) that controls the systems of the Discovery One spacecraft and interacts with the ship's astronaut crew. HAL 9000 is a fictional character in Arthur C. Artist's rendering of HAL's famous camera eye
