This is the new age of exploration. National Geographic explorer and film maker (Avatar, Titanic, Abyss) James Cameron embarks on a dive to the ocean's deepest point. Its the least known and explored place on earth.
In March 2012, National Geographic Explorer-in-Residence James Cameron will tackle his biggest challenge ever—a solo journey to Challenger Deep, the deepest known point in the ocean. Challenger Deep is 10.99 kilometers (6.83 miles) deep and is found at the southern end of the Mariana Trench near Guam. Years in the making, this feat has been compared to landing on the moon.
