''2010: Odyssey Two'' is a 1982 science fiction novel by Arthur C. Clarke. It is the sequel to the 1968 novel ''2001: A Space Odyssey'', but continues the story of Stanley Kubrick's film adaptation with the same title rather than Clarke's original novel, which differed from the film in some respects. Set in the year 2010, the plot centers on a joint Soviet-American mission aboard the Soviet spacecraft ''Leonov''. The mission has several objectives, including salvaging the spaceship ''Discovery'' and investigating the mysterious "monolith" discovered by Dave Bowman in ''2001: A Space Odyssey''. It was nominated for the Hugo Award for Best Novel in 1983.〔(【引用サイトリンク】 1983 Award Winners & Nominees )〕 The novel was adapted for the screen by Peter Hyams and released as a film in 1984. ==Plot summary== The story is set nine years after the failure of the ''Discovery One'' mission to Jupiter.〔The novel version of ''2001'' featured the journey to Saturn instead: Clarke acknowledges this retroactive continuity in his author's foreword.〕 A joint Soviet-American crew,〔The Soviet Union did not dissolve until nine years after this book was written.〕 including Heywood Floyd from ''2001'', on the Soviet spaceship ''Alexei Leonov'' (named after the cosmonaut) arrives to discover what went wrong with the earlier mission, to investigate the monolith in orbit around the planet, and to resolve the disappearance of David Bowman. They hypothesize that much of this information is locked away on the now-abandoned ''Discovery One''. The Soviets have an advanced new "Sakharov" drive which will propel them to Jupiter ahead of the American ''Discovery Two'', so Floyd is assigned to the ''Leonov'' crew. However, a Chinese space station rockets out of Earth orbit, revealing itself to be the interplanetary spacecraft ''Tsien'', also aimed at Jupiter. The ''Leonov'' crewmembers think the Chinese are on a one-way trip due to its speed, but Floyd surmises that due to the large water content of Europa they intend to land there and use the water content to refuel. The ''Tsien'' The ''Leonov'' survives a dangerous aerobraking around Jupiter and arrives at ''Discovery''. Mission crewmember and HAL 9000's creator, Dr. Chandra, reactivates the computer to ascertain the cause of his earlier aberrant behaviour. After some time, Floyd is speaking to a Russian on board, who, for an instant, sees the Monolith open again, into a Stargate, as David Bowman escapes from the Monolith's universe back into ours. A sequence of scenes follows the explorations of David Bowman, who has been transformed into a non-corporeal, energy-based life-form, much like the aliens controlling the monoliths. During his journey, the Avatar of Bowman travels to Earth, making contact with significant individuals from his human past: He visits his mother and brushes her hair (shortly before she dies), and he appears to his ex-girlfriend on her television screen. In the novel, the aliens are using Bowman as a probe to learn about humankind. He then returns to the Jupiter system to explore beneath the ice of Europa, where he finds aquatic life-forms, and under the clouds of Jupiter, where he discovers gaseous life-forms. Both are primitive, but the aliens deem the Europan creatures to have evolutionary potential. An apparition of Bowman appears before Floyd, warning him that they must leave Jupiter within 15 days. Floyd has difficulty convincing the rest of the crew at first, but then the monolith vanishes from orbit. The ''Leonov'' crew devises a plan to use the ''Discovery'' as a "booster rocket", enabling them to return to Earth ahead of schedule. Unfortunately, HAL and the ''Discovery'' will be trapped in Jupiter's orbit, with insufficient fuel to escape. The crew are worried that HAL will have the same neuroses on discovering that he will be abandoned yet again, so Chandra must convince HAL that the human crew is in danger. The ''Leonov'' crew flees Jupiter as a mysterious dark spot appears on Jupiter and begins to grow. HAL's telescope observations reveal that the "Great Black Spot" is, in fact, a vast population of monoliths, increasing at an exponential rate, which appear to be eating the planet. By acting as self-replicating 'von Neumann' machines, these monoliths increase Jupiter's density until the planet achieves nuclear fusion, becoming a small star. In the novel, this obliterates the primitive life forms inhabiting the Jovian atmosphere, which the Monoliths' controllers had deemed very unlikely to ever achieve intelligence unlike the aquatic life of Europa. As Jupiter is about to transform, Bowman returns to ''Discovery'' to give HAL a last order to carry out. HAL begins repeatedly broadcasting the message The creation of the new star, which Earth eventually names Lucifer, destroys ''Discovery''. However, in appreciation for HAL's help, Bowman has the aliens which control the monoliths remove HAL's artificial intelligence from ''Discoverys computer core and transform him into the same kind of life form as David Bowman, and becomes his companion. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「2010: Odyssey Two」の詳細全文を読む スポンサード リンク
