Where Is the Deepest Place On Earth?

In the pacific ocean to the southeast of Japan, there is a very deep trench called the Mariana trench, and at the southern tip there is a small part called the Challenger Deep


With a measured depth of approximately 35,797 feet (10, 910.9 metres) below sea level, a journey to the bottom of the Challenger Deep is nearly seven miles (11.2654 kilometres), making it the deepest known place on Earth.


The Challenger Deep is named after a British Royal Navy ship called the HMS Challenger. The Challenger was the first ship to measure the depths of what is now known as the Challenger Deep.


The trench was measured by “sounding,” which involves dropping a very long line with a weight at the end into a body of water.


Only four descend to the challenger deep have ever been successful.

The first was in 1960 by a vessel called the Trieste. Trieste’s journey into the trench took almost five hours, while its return to the surface took three hours and 15 minutes.

The second was the in 1995 by an unmanned deep-sea robotic probe named Kaiko.

The third was took place in 2009, when the U.S. Navy sent the Nereus on an exploration. The Nereus is a hybrid remotely-operated vehicle, also known as an HROV.
The Nereus spent more than 10 hours at the bottom of the Challenger Deep, sending live video and data back to a ship at the surface.

The fourth and final was 2012 by solo-diver James Cameron in the DEEPSEA CHALLENGER.
