Among real space explorers, few songs have resonated as powerfully as David Bowie's iconic "Space Oddity," the soulful ballad of a solitary fictional astronaut, Major Tom. Bowie, who died on Sunday from cancer, published the song as a single in July 1969 - the year and month of the first Apollo moon landing.

Bowie has said he was inspired to write the song after watching Stanley Kubrick's epic film "2001: A Space Odyssey," which came out a year earlier.
The song opens with Major Tom launching into space. Ground Control tells him "Take your protein pills and put your helmet on ... Commencing countdown, engines on ... Check ignition and may God's love be with you."
Once in space, the accolades pour in.
"You've really made the grade," Ground Control tells Major Tom. "The papers want to know whose shirts you wear."

Then it's time for work - a spacewalk - and Major Tom picks up the storyline:
"I'm stepping through the door And I'm floating in a most peculiar way.
And the stars look very different today For here Am I sitting in a tin can Far above the world Planet Earth is blue And there's nothing I can do."
Canadian astronaut Chris Hadfield was so inspired by Bowie's song that he made a music video of "Space Oddity" while he was aboard the International Space Station in 2013, catapulting the song back into the public eye.
"Ashes to ashes, dust to stardust. Your brilliance inspired us all. Goodbye Starman," Hadfield posted on Twitter on Monday.
