Hamza also wrotethis: "I consider myself to be forged in steel. The path ofjihad for the sake of God is what we live." Curiosity - Rover"Curiosity" explores whether life could have begun on Mars. IsEarth the only planet in our solar system that has life on it?Scientists can't say for sure, but it's possible life couldhave flourished on Mars based on data gleaned by the Mars rover"Curiosity." Bill Whitaker reports on the sights and databeamed back more than 30-million miles from Mars by Curiosity,information that's telling scientists a lot about the RedPlanet and Earth. Whitaker visits the Jet Propulsion Laboratoryin Pasadena, California, to bring viewers on a trip to Mars.JPL monitors show incredible images from its surface, such asa sunset and Martian terrain. But information from Curiosity'sinternal lab offers evidence of essential organic chemicals,leading JPL's Chief Engineer Rob Manning to consider an evenwilder trip. "Could have been that Mars was habitable beforeEarth was and life got its foothold on Mars and took itsjourney to Earth and we're all Martians." Manning explains."When a meteor comes along and hits Mars, a rock from Mars canbe lifted up, travel in circles around the sun until somedayit will bump into Earth," he tells Whitaker. "We've found Marsrock…we've found them all over the Earth." Manning says Earthrocks have traveled to Mars in the same way and that it'spossible life could have survived the journey.
