This is how i view this song (if that makes sense)

00:00 You are walking to the spaceship and your space team is wishing you luck

00:44 You enter the ship feeling nervous and a bit scared

00:55 But you put your big boy or girl pants on and stayed strong

01:06 You say your prayers hoping that everything goes right and your team starts the countdown

01:27 Countdown and Blast Off!

01:55 you enter the Troposphere

02:06 Stratosphere

02:17 Mesosphere

02:39 Thermosphere

03:01 Exosphere

03:23 Congratulations You have reached Space
