[Space Oddity] What exactly happened to Major Tom?

We know that Major Tom was an astronaut and on his mission, Ground Control lost contact with him as he drifted away. However at some point later, a biographer mentions that he did return home, yet his original biographer then describes him as a junkie, in an attempt to discredit him.

What happened on that mission? What is NASA covering up? What is the truth about Major Tom?

Major Tom died, but is continued to be worshiped.

From wikipedia:

In the music video of Bowie's 2015 song "Blackstar" (on the album of the same name, released in 2016 two days prior to the artist's death), a dead astronaut is depicted. His skull is retrieved by an alien female who takes it back to what could be considered a cult which subsequently worships the relic. This astronaut was speculated to be a depiction of Major Tom's final fate.[5][6][7] Video director Johan Renck said on a BBC documentary "to me, it was 100% Major Tom"
