I feel there is a lot common in an astronaut and an artist. They both contribute a lifetime to achieve what no on else could achieve.
Astronaut ventures into new worlds and space while an artist wanders amidst his ideas and imagination to create something unique and beautiful.
The astronaut ( aka artist) here was trapped in his comfort zone, his own colorful realm. HE aspires to venture out of this vibrant and easy life to the space where nothingness resides. The space which is scary yet exciting, you never know what you'll find here but the astronaut will eventually step out and conquer his inhibitions. The astronaut finally ventures out of his bubble and lift off. Just like the artist who break away the shackles of doubts and disbelief, astronaut is on his way to find something in the mundane nothingness.
