The main characters in '2001 a space odyssey short story' include Dr. Dave Bowman, who is a brave and inquisitive astronaut. He is at the forefront of the exploration and the one who has the most direct encounters with the mysterious monolith. HAL 9000, the super - intelligent computer, is also a major character. HAL has its own 'personality' and goals, which often conflict with those of the human crew. There are other astronauts as well, but they are more in the background compared to Bowman and HAL.
