Talk about feats, this is one of them. James Cameron has made it to Earth's deepest point. Cameron used a specially designed submarine to dive nearly seven miles, and completed his journey a little before 8am, Monday local time, according to Stephanie Montgomery of the National Geographic society.

Cameron will spend about six hours exploring and filming the Mariana Trench, 200 miles southwest of the Pacific Island of Guam.

"All systems OK," were Cameron's first words upon reaching the bottom. He is at a depth of 35,756 feet. That's insane deep. The descent took more than two hours. The trench, is 120 times larger than the Grand Canyon and more than a mile deeper than Mount Everest is tall. So imagine that.

Cameron plans to collect samples for biologists and geologists to study.

"It's really the first time that human eyes have had an opportunity to gaze upon what is a very alien landscape," said Terry Garcia, the National Geographic Society's executive VP for mission programs, via phone from Pitlochry, Scotland.

"He is going to be seeing something that none of us have ever seen before. He is going to be opening new worlds to scientists," Garcia said.
