Lift off for Nasa's Mars probe
Nasa has launched a spacecraft on a nine-month journey to Mars, where it will dig below the surface for clues to the existence of past or present life.
The Phoenix probe lifted off at 0526 EDT (1026 BST) from Cape Canaveral, Florida, atop a Delta II rocket.
If everything goes to plan, Phoenix should arrive at Mars in late May 2008.
Phoenix was scheduled to launch on Friday, but severe weather conditions prevented fuelling of the rocket's second stage.
