pleeeeeeeeeeease help!

i would translate your phrase to me "through exstrem adversity to victory " but thats my interpitation of something trying to be said..."through the thorns to the stars" would be to me more like" per ab spineus ad ab stellans"

Per aspera ad astra - The Hard Way to the Stars.

It means you'll have a hard time before achieving an outstanding work.

http://www.sacklunch.net/Latin/P/perasperaadastra.html tells you the meaning.
