Making the nearly 11-kilometer descent to the deepest place on Earth, exploring the ocean floor, conducting scientific experiments, collecting samples, and returning safely to the surface requires a very sophisticated craft. It needs to be capable of withstanding tremendous pressures, if it is to explore the place less understood than the farthest reaches of space.
In 2012 James Cameron, in a sub like no other, conducted a dive to the deepest part of the ocean, the Mariana Trench. Unfortunately I was one of the last people to see the sub, prior to its damage in a fire during transportation. I was so incredibly impressed to see the vessel, investigate it and realize how small the sphere where the pilot sits is. I did not want to leave the place and asked the scientists thousands of questions. Here I was, touching something that reminded me of how amazing humanity can be, of how we can use technology, our ingenuity and hard work to explore, learn and act. I felt shivers down my spine. Maybe, one day, a woman will also dive to the deepest part of the ocean, I thought.
This journey has only once been made prior to Cameron’s dive, by Jacques Piccard and Don Walsh. On 23 January 1960, the bathyscaphe Trieste reached the ocean floor in the Challenger Deep (the deepest southern part of the Mariana Trench). This was the first time a vessel, manned or unmanned, had reached the deepest known point of the Earth’s oceans. The two pioneers spent about 20 minutes on the ocean floor, but unfortunately the landing caused stirring up of the sediments and for the entire time the clouds of silt were everything that could be seen from the portholes.
