2010: Odyssey Two is a 1982 science fiction novel by British writer Arthur C. Clarke. It is the sequel to his 1968 novel 2001: A Space Odyssey, though Clarke changed some elements of the story to align with the film version of 2001.
Set in the year 2010, the plot centres on a joint Soviet-US mission aboard the Soviet spacecraft The Cosmonaut Alexei 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. The novel was adapted for the screen by Peter Hyams and released as the film 2010: The Year We Make Contact in 1984. The story is set nine years after the failure of the Discovery One mission to Jupiter.
