3001: The Final Odyssey is the last instalment of the Space Odyssey book series. It centers around the revival of Frank Poole in the year 3001 and his attempts to save humanity from disaster and to readjust to his new futuristic lifestyle, considering the fact that man has made many technological advances.
3001 follows the adventures of Frank Poole, the astronaut killed by the HAL 9000 in 2001: A Space Odyssey. In the Fourth Millennium, Poole's freeze-dried body is discovered in the Kuiper belt by a comet-collecting space tug named the Goliath, and revived. Poole is taken home to learn about the Earth in the year 3001.
3001 introduces Star City, an enormous Earth habitat with four gigantic space elevators, protruding evenly from the Earth’s Equator, connected by a habitat ring.
It is also mentioned that the TMA-1, the black monolith found on the Moon in 1999, has been brought to Earth in 2006 and installed in front of the United Nations Building in New York City.
