"I was just trying to be a good dad!" Hadfield said with a laugh. "I mean really, at the start, my son was insistent. He was like ‘Dad, you have to do this, everyone wants you to do it!' It was one of those ‘Right, OK, I'll try to squeeze it in' projects."
Working with friends and fellow Canadians Emm Gryner, an award-winning musician, and Joe Corcoran, a music producer based in LA, Hadfield crafted the vocals. Then his son Evan urged him to record the now-famous music video.

"'Space Oddity' really (came about) because my son was insistent ... and he was right. The worldwide response was phenomenal and continues to be."
By this point, Hadfield had reached a million followers on Twitter and had garnered a huge following on Reddit, Tumblr and Facebook (to name just a few social networks), but being in space meant that he wasn't fully aware of how his popularity on the ground had skyrocketed.
"I wasn't all that aware ... Once in a while I'd get a tweet from William Shatner or from another celebrity and that was kind of delightful," he said. "It was like ‘Hey, other people are paying attention to what we are doing!' but I think that that is the slice that people see, they thought that was the priority of what I was doing."
