Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April–4 May 2019). The Challenger Deep (CD) is the deepest known point in the Earth's seabed hydrosphere, a slot-shaped valley in the floor of Mariana Trench, with depths exceeding 10,900 meters. [1]
The Mariana Trench is an oceanic trench located in the western Pacific Ocean, about 200 kilometres (124 mi) east of the Mariana Islands; it is the deepest oceanic trench on Earth. It is crescent-shaped and measures about 2,550 km (1,580 mi) in length and 69 km (43 mi) in width. The maximum known depth is 10,984 ± 25 metres (36,037 ± 82 ft ...
Sonar mapping of the Challenger Deep by the DSSV Pressure Drop employing a Kongsberg SIMRAD EM124 multibeam echosounder system (26 April – 4 May 2019). The Challenger Deep is a relatively small slot-shaped depression in the bottom of a considerably larger crescent-shaped oceanic trench, which itself is an unusually deep feature in the ocean floor.
In June 2020 Sullivan traveled on an expedition aboard the Triton Submarines DSV Limiting Factor to the bottom of the Challenger Deep in the Mariana Trench, becoming the first woman and eighth person to reach the deepest known point in Earth's oceans, [56] [57] [58] and the first person to travel both to Challenger Deep and into space.

Trieste is a Swiss-designed, Italian-built deep-diving research bathyscaphe. In 1960, it became the first crewed vessel to reach the bottom of Challenger Deep in the Mariana Trench, the deepest point in Earth's seabed. [2] The mission was the final goal for Project Nekton, a series of dives conducted by the United States Navy in the Pacific ...
On 23 January 1960, Piccard and Lt. Don Walsh reached the floor of the Mariana Trench located in the western North Pacific Ocean. The depth of the descent was measured at 10,916 meters (35,813 feet); later, more accurate, measurements during 1995 found the Mariana Trench to be slightly less deep at 10,911 m (35,797 ft). The descent took four hours.
On 5 March 2021, Harding and Victor Vescovo dived to the deepest point of the Mariana Trench, the Challenger Deep, at a depth of approximately 11,000 m (36,000 feet), in the two-person deep-submergence vehicle DSV Limiting Factor, setting the Guinness World Records for greatest distance covered at full ocean depth and greatest time spent at ...
He had previously visited the South Pole numerous times, descended more than 10,000m to the Challenger Deep of the Mariana Trench, and flew to space in 2022 as part of the suborbital Blue Origin O ...
