Will.i.am song played from surface of Mars

Will.i.am said he could not explain how amazing it was to have his song, Reach for the Stars, to be broadcast from another planet.

Speaking to students at the Jet Propulsion Laboratory in Pasadena, California, he said the song will tell them to raise their expectations of what they can achieve for themselves, and surround themselves with people who believe in them.

During the event, Will.i.am's i.am angel Foundation and Discovery Education announced a $10m classroom education initiative that will reach 25 million students annually, including 'many from underserved communities'.
