Famous Expeditions to the World’s Deepest Point His dive was part of the Five Deeps Expedition to reach the bottom of every ocean on Earth. 2020: Former NASA astronaut Kathryn Sullivan became the first woman to reach the deepest point in the ocean and the first person to travel both to space and to the Challenger Deep.

This is the Kola Superdeep Borehole, the deepest manmade hole on Earth and deepest artificial point on Earth. During the Cold War, there was a race by the superpowers to drill as deep as possible into the Earth’s crust – and even to reach the mantle of the planet itself.
