Will.i.am has premiered his new single - from Mars.
The Nasa rover Curiosity beamed to Earth the Black Eyed Peas singer's new song Reach For The Stars, in the first music broadcast from another planet, to the delight of students who gathered at the Jet Propulsion Laboratory in Pasadena, California, to listen.
The song had been uploaded to the rover, which landed near the equator of Mars, and played it back - a journey of some 700 million miles.
The musician, who promotes science and mathematics education, was among more than a dozen celebrities invited to JPL to watch Curiosity's landing earlier this month. Others included Wil Wheaton, Seth Green and Morgan Freeman.
In 2008 Nasa beamed the Beatles' Across The Universe into the cosmos to commemorate the 40th anniversary of the song.
