(Reuters) - For the first time, humans will visit the deepest part of each of the five oceans, plunging to the sea floor using a two-person craft designed to withstand the intense pressures more than 5.5 miles (9 km) below the surface.

The project, known as Five Deeps Expedition, will use a special submersible vehicle that took more than three years to build. It is made of titanium and other special materials that can dive to the bottom of the ocean, said Victor Vescovo, an explorer who will pilot the vehicle after it leaves its supporting boat and descends toward the deepest parts of the ocean.

“I’m very much looking forward to pushing not only the limits of the technology and myself and my crew, but also hopefully push humanity forward a little bit in terms of our understanding of our world and showing what we can do as a species,” said Vescovo, who has climbed the world’s seven highest mountain peaks and trekked to both the North and South Poles.

The maker of the submersible vehicle, Triton Submarines LLC of Vero Beach, Florida, said on the company website that it is the only submersible certified to carry humans on dives of 36,000 feet (11,000 meters). Discovery and Science Channel will capture the entire mission for a project known as “Deep Planet” that will air in 2019.
