Deepsea Challenger
On March 25th, 2012 film maker James Cameron
became the first person to descend to the
deepest point below the ocean's surface,
6.8 miles down in the Mariana Trench

Deepsea Challenger (DVC 1) is a 7.3-metre (24 ft) deep-diving submersible designed to reach the bottom of Challenger Deep, the deepest known point on Earth. On 25 March 2012, Canadian film director James Cameron piloted the craft to accomplish this goal, becoming the first person to reach Challenger Deep in a one-man craft. Built in Sydney, Australia by research and design company Acheron Project Pty Ltd, the Deepsea Challenger includes scientific sampling equipment and high-definition 3-D cameras, and reached the ocean's deepest point after roughly two hours of descent from the surface.

On 25 March 2012, Cameron reached the bottom of the Mariana Trench, the deepest part of the ocean at 11 km (6.8 miles) depth, and of the Earth, in the Deepsea Challenger submersible. It was the fourth dive to the Challenger Deep and the second manned dive (with a maximum recorded depth slightly less than that of the Trieste's 1960 dive). It was the first solo dive and the first to spend a significant amount of time (three hours) exploring the bottom.

The first Tweet from the deepest point on Earth:

"Just arrived at the ocean's deepest pt. Hitting the bottom never felt so good. Can't wait to share what I'm seeing w/ you @DeepChallenge" —James Cameron, Telegraph.co.uk
