James Cameron is apparently missing his Titanic fame, and he’s willing to go pretty far to recapture it -- like nearly seven miles straight down to the bottom of the ocean. (Hey, it worked for the ship.) Cameron is travelling in a submersible to the bottom of the Mariana Trench, the lowest known point on Earth.
Cameron recently started descending 6.8 miles below the surface of the water in a vessel that he helped design, the Deepsea Challenger. The trip takes nine hours one-way, which would normally prompt a lot of “are we there yets?” but Cameron is making the voyage by himself. He’s only the third person to make the journey down the Mariana Trench, and the first to do it solo.
