What Leads Up to the Ending
Millions of years ago, a black monolith helped early humans learn to use tools. In 1999, another monolith is found on the Moon, sending a signal toward Saturn. The ship Discovery is sent, run by the intelligent computer HAL 9000. HAL kills most of the crew to protect the mission's secret.
What Happens at the End of 2001: A Space Odyssey
Bowman survives HAL's attack and disconnects its higher functions while HAL pleads and regresses to its earliest memories. Alone, he reaches Iapetus and finds a giant monolith that opens into a Star Gate. He passes through a cosmic “Grand Central Station” of alien traffic and arrives in a hotel suite built by the aliens from old TV images to make him comfortable. He sleeps, and as he does, his memories are absorbed and his body falls away. He is reborn as the Star-Child, able to travel through space without a ship. He returns to Earth, harmlessly detonates the nuclear weapons in orbit and pauses to decide what to do with his new power.

Is the Ending Happy or Sad?
Most readers describe the ending of 2001: A Space Odyssey as awe-inspiring. How you feel about it usually depends on what you hoped for the characters and what you expected Arthur C. Clarke to do with the story, so it is worth asking friends how they felt before you compare notes.
Who Will Like This Ending
Readers who enjoy endings that are awe-inspiring will find a lot to talk about here. If you prefer every thread tied up neatly, it helps to know in advance how Arthur C. Clarke closes the story, which is exactly why many readers look it up. Either way, the final chapters reward a second look once you know where everything is heading, because small details from the middle of the book start to matter. If you are reading with a group, agree beforehand whether everyone has finished, so nobody has the last chapters spoiled.
Book Versus Adaptation
Stanley Kubrick's 1968 film was made alongside the novel but leaves the ending more mysterious.
