How Many People Have Been to the Mariana Trench?

Reaching the Mariana Trench, Earth's deepest point, is a feat that few have accomplished. This underwater valley's bottom, known as the Challenger Deep, has been visited by only a handful of daring explorers since the first successful dive in 1960.

Jacques Piccard and Don Walsh were the first humans to reach the Mariana Trench's deepest point. Since then, only five daring explorers have followed in their path till 2021, exploring this alien underwater world's unseen depths.

Summary of the people who have visited the Mariana Trench

A Glimpse into Mariana Trench's History

In 1960, Jacques Piccard and Don Walsh became the first pioneers to venture down to the Mariana Trench's deepest point. The duo dove in the specially designed bathyscaphe Trieste to endure the extreme pressure at the bottom of the trench.

More Brave Visitors Came Following

In the years following the inaugural expedition, a small cohort of five explorers dared to visit this fearsome and fascinating underwater abyss. Among them was Hollywood director James Cameron, renowned astronaut and oceanographer Kathy Sullivan, mountaineer Vanessa O'Brien, high-stakes adventurer Victor Vescovo, and British-American computer game developer Richard Garriott.

A Gruelling Dive

These daring expeditions are laden with difficulty and danger. The trench’s extreme depth comes with an equally extreme pressure, about 1,071 times the atmospheric pressure at sea level. Additionally, the temperature near the bottom is near freezing, around 1 degree Celsius. The submersible vehicles used must be incredibly strong, resilient and technologically advanced to withstand these harsh conditions.

Discoveries from the Deep

Despite the inherent dangers, diving into the Mariana Trench has yielded an incredible trove of scientific data. Explorers have discovered new species of animals, alien-like bacteria, and valuable insights into the Earth’s geological formations, enriching our understanding of this extreme ecosystem.

Inspirations from the Intrepid

The sheer human ingenuity and bravery showcased in these expeditions serve as a source of inspiration. They fuel our curiosity and push the boundaries of what we believe to be possible, paving the way for the next wave of explorers and researchers to conquer such extreme environments.

At a glance, just seven individuals, as of 2021, have dived to the Challenger Deep — the question of how many people have been to the Mariana Trench gets a little easier to answer.
