If you've already experienced the eye-watering glory that is Interstellar, you'll recognise this music.
It's from a key scene when Matthew McConaughey leaves Earth to begin his journey to find habitable planets across the galaxy. It's a truly intense, emotional scene - made all the more so by Hans Zimmer's fantastic score.
The folks over at LucidDigital took Hans Zimmer's piece, entitled 'Stay', and put it to an actual rocket launch.
Orion, NASA's new deep-space exploration craft, is intended for use on the eventual manned mission to Mars and parts beyond.
We're not yet sure if McConaughey's involved in the next mission. Probably not, considering he's an actor and stuff.
