Flight controllers at NASA\u2019s Jet Propulsion Laboratory in Pasadena, California, leaped out of their seats and erupted in screams, applause and laughter as the news came in.<\/li>\n<li>\u201cTouchdown confirmed!\u201d a flight controller announced.<\/li>\n<li>The three-legged InSight spacecraft reached the surface after being slowed by a parachute and braking engines, the space agency said. Updates were coming in via radio signals that take more than eight minutes to cross the nearly 100 million miles (160 million kilometers) between Mars and Earth.<\/li>\n<li>It was NASA\u2019s ninth attempt to land at Mars since the 1976 Viking probes. All but one of the previous U.S. touchdowns were successful.<\/li>\n<li>NASA last landed on Mars in 2012 with the Curiosity rover.<\/li>\n<li>Viewings were held coast to coast at museums, planetariums and libraries, as well as New York\u2019s Times Square.<\/li>\n<li>The plan called for the spacecraft to go from 12,300 mph (19,800 kph) to zero in six minutes flat as it pierced the Martian atmosphere and settled on the surface.<\/li>\n<li>\u201cLanding on Mars is one of the hardest single jobs that people have to do in planetary exploration,\u201d said InSight\u2019s lead scientist, Bruce Banerdt. \u201cIt\u2019s such a difficult thing, it\u2019s such a dangerous thing that there\u2019s always a fairly uncomfortably large chance that something could go wrong.\u201d<\/li>\n<li>Mars has been the graveyard for a multitude of space missions. Up to now, the success rate at the red planet has been only 40%, counting every attempted flyby, orbital flight and landing by the US, Russia and other countries since 1960.<\/li>\n<li>The US, however, has pulled off seven successful Mars landings in the past four decades, not counting InSight, with only one failed touchdown. No other country has managed to set and operate a spacecraft on the dusty red surface.<\/li>\n<li>InSight was shooting for Elysium Planitia, a plain near the Martian equator that the InSight team hopes is as flat as a parking lot in Kansas with few, if any, rocks.<\/li>\n<li>This is no rock-collecting expedition. Instead, the stationary 800 pound (360kg) lander will use its six-foot (1.8-meter) robotic arm to place a mechanical mole and seismometer on the ground. The self-hammering mole will burrow 16 feet (5 metres) down to measure the planet\u2019s internal heat, while the seismometer listens for possible quakes.<\/li>\n<li>Nothing like this has been attempted before at our next-door neighbour, nearly 100 million miles (160 million km) away. No lander has dug deeper than several inches, and no seismometer has ever worked on Mars.<\/li>\n<li>By examining the interior of Mars, scientists hope to understand how our solar system\u2019s rocky planets formed 4.5 billion years ago and why they turned out so different\u2014Mars cold and dry, Venus and Mercury burning hot, and Earth hospitable to life.<\/li>\n<li>InSight has no life-detecting capability, however. That will be left to future rovers. NASA\u2019s Mars 2020 mission, for instance, will collect rocks that will eventually be brought back to Earth and analyzed for evidence of ancient life.<\/li>\n<li><i>This story has been published from a wire agency feed without modifications to the text.
