The New Horizons spacecraft team revealed close-up photos of those plains, which they’re already unofficially calling Sputnik Planum after the world’s first man-made satellite.The peaks are now known, informally at least, as the Norgay Montes. Tenzing Norgay was the Sherpa guide for Sir Edmund Hillary when they conquered Mount Everest in 1953. The huge, encompassing heart-shaped region already bears the last name of Clyde Tombaugh, the late American astronomer who discovered Pluto in 1930.Tenzing Norgay and New Zealand's Edmund Hillary step onto the summit of Mount Everest, the world's tallest mountain. First they shake hands, as proper members of a British mountaineering team, but then Tenzing grabs Hillary in an exuberant hug at the top of the world.Tenzing is unfamiliar with the camera, so there is no photo of Hillary at the summit. The two climbers then begin their descent back to high camp #9. They have conquered Chomolungma, the Mother of the World, 29,029 feet (8,848 meters) above sea level.
