By MARK PRIGG: After travelling eight-and-a-half months and 352 million miles, Nasa's rover Curiosity finally landed on Mars at 5.33 GMT (1.33 EDT) this morning. The high-tech craft hit the top of the Martian atmosphere at 13,000mph, and was then slowly lowered by a radical floating 'sky crane' before gently arriving in a massive crater. The news was greeted with cheers and shouts in Nasa's Pasadena Mission Control, and within seconds the craft had sent back the first pictures of its new home. 
Jubilant scientists hugged, wept and distributed Mars bars to each other as mission controllers confirmed the landing. 'Touchdown confirmed', controllers said. 'We are wheels down on Mars. Oh, my God.' Nasa Administrator Charles Bolden hailed the success as a big step towards sending men to the red planet. 'Today, the wheels of Curiosity have begun to blaze the trail for human footprints on Mars,' he said. 
The mission was hailed by President Obama, who said 'Tonight, on the planet Mars, the United States of America made history.' The trickiest moment of the landing came in a truly out of this world gymnastics

routine during Curiosity's 'seven minutes of terror' plummet through the atmosphere. When the rover had safely navigated its landing and touched down on the face of the Red Planet, NASA scientists exploded with delight and some even broke down in tears, overwhelmed at the success of the
decades-long project. Nasa was ready for the 'Super Bowl of planetary exploration,' said Doug McCuistion, head of the Mars exploration program at NASA headquarters. 'We score and win or we don't score and we don't win,' he said. Curiosity's trajectory was so accurate that engineers decided to wave off a last chance to tweak its position before atmosphere entry. 'We're ready to head in,' said mission manager Brian Portock.
Not ones to tempt fate, flight controllers broke out the 'good luck' peanuts before Curiosity takes the plunge as part of a long-running tradition. One scientist who could relate to the building anxiety was Cornell University planetary scientist Steve Squyres, who headed NASA's last successful rover mission in 2004.This time around, Squyres has a supporting role and planned to view the landing with other researchers in the 'science bullpen.' 'Landing on Mars is always a nerve-racking thing. You're never going to get relaxed about something like landing a spacecraft on Mars,' he said. Sunday's touchdown attempt was especially intense because NASA is testing a brand new landing technique. Due to the communication delay between Mars and Earth, Curiosity was be on autopilot. There was also extra pressure because budget woes have forced NASA to rejigger its Mars exploration roadmap. 'There's nothing in the pipeline' beyond the planned launch of a Mars orbiter in 2013, said former NASA Mars czar Scott Hubbard, who teaches at Stanford University. Curiosity was launched to study whether the Martian environment ever had conditions suitable for microbial life. The last Mars rovers, twins Spirit and Opportunity, were cocooned in air bags and bounced to a stop in 2004. The plans for Curiosity called for a series of braking tricks, similar to those used by the space shuttle, and a supersonic parachute to slow it down. Next: ditch the heat shield used for the fiery descent. And in a new twist, engineers came up with a way to lower the rover by cable from a hovering rocket-powered backpack. At touchdown, the cords cut and the rocket stage crashes a distance away. The nuclear-powered Curiosity, the size of a small car, is packed with scientific tools, cameras and a weather station. It sports a robotic arm with a power drill, a laser that can zap distant rocks, a chemistry lab to sniff for the chemical building blocks of life and a detector to measure dangerous radiation on the surface. It also tracked radiation levels during the journey to help NASA better understand the risks astronauts could face on a future manned trip. After several weeks of health checkups, the six-wheeled rover could take its first short drive and flex its robotic arm. Source: Travelfwd+
