NASA's Curiosity rover is making global headlines as it travels uncharted territory on Mars, and it will venture into new realms back on Earth this week when it premieres a new will.i.am song. The Black Eyed Peas rapper's tune "Reach For The Stars" will be broadcast live from the surface of Mars, via Curiosity, at 1 p.m. PST (4 p.m. EDT/2000 GMT) on Tuesday to a news conference at NASA's Jet Propulsion Laboratory in Pasadena, California, the organization said in a statement on Monday.
