Don Walsh and Jacques Piccard Submarine: A Journey to the Deepest Part of the Ocean

In 1960, two pioneers, Don Walsh and Jacques Piccard, embarked on a historic expedition to the deepest part of the ocean. Their mission was to explore the Mariana Trench, a vast and mysterious region that had never been fully mapped or explored before. The journey was marked by bravery, innovation, and a thirst for discovery, and it paved the way for future oceanographic research.

The Quest for the Deepest Point

The Mariana Trench is a long, deep depression in the floor of the Pacific Ocean, located in the western Pacific Ocean. It stretches for more than 1,500 miles (2,500 kilometers) and reaches a maximum depth of approximately 36,000 feet (10,973 meters). The trench is a challenging environment, characterized by extreme pressure, darkness, and near-freezing temperatures.

Don Walsh and Jacques Piccard were aware of the risks involved, but they were driven by a desire to explore the unknown. They designed and built a specially designed deep-diving submersible, called the Bathyscaphe Trieste, which was capable of withstanding the extreme pressure of the deep ocean.

The Bathyscaphe Trieste

The Bathyscaphe Trieste was a remarkable achievement in engineering and design. The submersible was made of stainless steel, with a spherical hull that was designed to withstand the pressure of the deep ocean. It was 23 feet (7 meters) long and 7 feet (2.1 meters) in diameter, and it weighed approximately 25 tons.

The Trieste was powered by electric motors, and it had a depth rating of approximately 20,000 feet (6,100 meters). It was capable of descending at a rate of 1,000 feet (305 meters) per minute, and it could stay submerged for up to 6 hours.

The Journey to the Bottom

On January 23, 1960, Don Walsh and Jacques Piccard embarked on their historic journey to the bottom of the Mariana Trench. They boarded the Bathyscaphe Trieste at Eureka, California, and set off on the long journey to the trench.

The descent was slow and deliberate, with the Trieste stopping every 1,000 feet (305 meters) to check its instruments and ensure that everything was functioning properly. The pressure increased rapidly as they descended, and the temperature dropped to near-freezing levels.

At approximately 35,800 feet (10,900 meters), the Trieste reached the bottom of the trench. The pressure was over 1,000 times greater than the pressure at sea level, and the darkness was total.

The First Descent to the Bottom

The moment of truth arrived when Don Walsh and Jacques Piccard reached the bottom of the trench. They had broken through the ice-like crust that covers the ocean floor, and they had reached the lowest point on Earth.

The scene was surreal, with the darkness illuminated only by the faint glow of the Trieste’s lights. The silence was absolute, broken only by the sound of the submersible’s instruments and the gentle hum of its engines.

The Return Journey

After spending approximately 20 minutes at the bottom of the trench, Don Walsh and Jacques Piccard began their ascent. The journey back to the surface was long and slow, with the Trieste stopping every 1,000 feet (305 meters) to check its instruments and ensure that everything was functioning properly.

The Trieste finally broke through the surface on January 24, 1960, after a journey of over 8 hours. Don Walsh and Jacques Piccard had successfully reached the bottom of the Mariana Trench, and they had set a new record for the deepest dive in history.

Legacy of the Journey

The journey of Don Walsh and Jacques Piccard to the bottom of the Mariana Trench was a groundbreaking achievement that paved the way for future oceanographic research. It demonstrated the possibility of exploring the deepest parts of the ocean, and it showed that man could withstand the extreme conditions of the deep sea.

The Bathyscaphe Trieste was retired after its historic dive, but it has been preserved and is now on display at the National Geographic Museum in Washington, D.C.
