An accurate transcription for easy piano notated precisely as it should be performed to reduce ambiguity. Lyrics and vocables ("ah-ah"s) are always included in my sheet music because I think we should always sing while playing piano (even when playing classical pieces). Harmony chords above the upper stave are for those who want to make their own arrangements by breaking chords in arpeggios or other patterns in the left hand.
The chorus is colored blue for your convenience. I notate verses/choruses differently because in modern pop-music they are arranged differently purely for the aesthetic enjoyment of variation.
I also doubled note values to make sightreading easier for beginners.
About the song
"The Astronaut" is a song with a homophonic texture — the instrumental part provides a harmony to support the vocal but lacks its own melody. Piano is an instrument that can play a melody and an accompaniment simultaneously.
The key is F Major.
A chord change marks time and musical structure rather than creates a harmonic pull.
Of course I consider filling your requests of sheet music except for not popular tracks.
