List of people who descended to Challenger Deep

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.

[3] In 1960, Don Walsh and Jacques Piccard were the first two humans to reach Challenger Deep, completing that dive as a team.

Piccard, Walsh and Cameron remained the only people to reach the Challenger Deep until 2019, when regular dives in DSV Limiting Factor began.

Astronaut Kathryn D. Sullivan and mountaineer Vanessa O'Brien were the first two women to visit Challenger Deep in 2020.

These individuals will have descended at least 10,900 m (35,761 ft) into one of the three pools (western, central or eastern) that constitute Challenger Deep.
