“Titanic” director James Cameron could dive as early as this weekend to the deepest place on Earth, further than any other human has on a solo mission, so long as the weather cooperates. The Canadian filmmaker left the tiny Pacific atoll of Ulithi on Saturday headed for the the Mariana Trench's Challenger Deep, which plummets 6.8 miles (11 kilometers) down in the Pacific Ocean, according to mission partner the National Geographic scientific institution. His goal is to become the first human to visit the ocean's deepest point in more than 50 years, and to bring back data and specimens. “If seas remain calm -- a big if -- the team may proceed with Cameron's submersible mission to the trench's Challenger Deep this weekend,” a National Geographic News report said. It said the submersible that Cameron designed, a “vertical torpedo” of sorts, already successfully completed an unpiloted dive Friday. __
