Nasa Atlas 5 - Mars Rocket Launch Mars Rover Launch ''Curiosity'' 26/11/11 Nasa Launches another of its mars rovers, this one being its most expensive, dubbed 'curiosity' it is scheduled to arrive at the mineral-rich Martian 'Gale Crater' next August. NASA's biggest and most-expensive robotic rover has blasted off from Cape Canaveral on a voyage of discovery. The probe, nicknamed Curiosity, is scheduled to arrive at the mineral-rich Martian 'Gale Crater' next August. It aims to search the surface for clues about whether the planet has ever had a life-friendly environment.

A narrated play-by-play of Curiosity's entry, descent, and landing on Mars! This 4-minute animation depicts key events of NASA's Mars Science Laboratory mission, which will launch in late 2011 and land a rover, Curiosity, on Mars in August 2012.

NASA first found signs of water on Mars more than a decade ago, but earlier indications were that any existing water would be frozen and concentrated at the poles. NASA scientists believe that if there is liquid water on Mars, it would be highly salty and lie beneath the surface. That would explain why it would not freeze in the planet's frigid surface temperatures, which can fall to around 200 degrees below zero Fahrenheit (minus 128 degrees Celsius), or evaporate in its low air pressure.
