An expedition to the deepest place on this planet is set for later this month, in a custom-built one-man sub to be helmed by Hollywood director James Cameron. The vessel Deepsea Challenge will dive to the deepest part of the Mariana Trench, seven miles into the Challenger Deep, where Cameron will shoot 3-D video.
When Sir Richard Branson unveiled the Virgin Oceanic submarine, he noted that "More men have been to the moon than have been down further [underwater] than 20,000 feet." To that end, he and an explorer pal will take the submarine to the deepest trenches of the Atlantic, Pacific, Indian, Southern, and Arctic Oceans, feeding first-of-its-kind data and video to Google, to be added to Google's Earth and Maps databases. The deep sea is truly the final frontier on our planet, and Branson wants to make it as accessible as possible.
