The artist and members of the Mars Science Laboratory team spoke about the message behind the song and some of the cool science Curiosity will be carrying out on Mars.
After his song had debuted, will.i.am discussed why he chose a more orchestral piece. "I didn't want to do a song that was done on a computer, I wanted to show human collaboration and have an orchestra there and something that would be timeless and translated into different cultures - not have a hip-hop beat or a dance beat."
He also pointed out that to compose something orchestral isn't what is expected of an artist in his genre and that he felt that he broke some boundaries by doing so.
will.i.am also had some words of wisdom for the students in the JPL audience: "You have to think beyond. Anything is possible if you're disciplined." He did point out that it won't happen overnight, but if you stay focused, education can help you achieve anything you set your mind to - this was the ultimate message behind "Reach for the Stars."
