The lyrics of the song suggest that Major Tom is experiencing a range of emotions, including joy, wonder, loneliness, and a sense of isolation. The song also plays with the idea of the unknown and the vastness of space, as well as the potential for human exploration.
"Space Oddity" was released in 1969, just before the Apollo 11 mission, which saw the first humans land on the moon. The song was seen by many as an anthem for the space age and captured the excitement and anticipation surrounding space exploration at the time.
