NASA blasts off Mars-bound spaceship, InSight, to study quakes

NASA on Saturday launched its latest Mars lander, called InSight, designed to perch on the surface and listen for "Marsquakes" ahead of eventual human missions to explore the Red Planet."Three, two, one, liftoff!" said a NASA commentator as the unmanned spacecraft blasted off on a dark, foggy morning atop an Atlas V rocket at 4:05 am Pacific time (1105 GMT) from Vandenberg Air Force Base in California, marking NASA's first interplanetary launch from the US west coast.
