Historic dive
On January 23, 1960, Jacques Piccard and Don Walsh made history by completing the first manned dive to the bottom of the Challenger Deep, the deepest point in the Earth's oceans. Their dive was a major scientific and technological achievement, and it captured the imagination of people around the world.
Piccard and Walsh's dive was the culmination of years of planning and preparation. They used a specially designed submersible called the Trieste, which was equipped with a variety of instruments and cameras. The Trieste was lowered into the Challenger Deep on a cable, and it took Piccard and Walsh more than four hours to reach the bottom.
At the bottom of the Challenger Deep, Piccard and Walsh found a landscape that was unlike anything they had ever seen before. The water was dark and murky, and the pressure was so intense that it felt like they were being crushed. They also saw a number of strange and wonderful creatures, including sea cucumbers, jellyfish, and shrimp.
Piccard and Walsh spent about 20 minutes at the bottom of the Challenger Deep before they began their ascent. They emerged from the Trieste safely, and they were greeted by a cheering crowd. Their dive had been a success, and they had made history.
Piccard and Walsh's dive to the Challenger Deep was a major milestone in the history of exploration. It showed that humans were capable of reaching the deepest point in the Earth's oceans, and it inspired a new generation of explorers.
Deepest point
The Challenger Deep is the deepest point in the Earth's oceans. It is located in the Mariana Trench, which is a deep valley in the western Pacific Ocean.
- Location: Mariana Trench, western Pacific Ocean
- Depth: 11,034 meters (36,201 feet)
- Pressure: 1,086 bars (15,750 pounds per square inch)
- Temperature: 1 degree Celsius (34 degrees Fahrenheit)
The Challenger Deep is an extreme environment. The water pressure at the bottom of the trench is more than 1,000 times greater than the pressure at sea level. The temperature is also very cold, and there is no sunlight. Despite these harsh conditions, the Challenger Deep is home to a variety of creatures, including sea cucumbers, jellyfish, and shrimp.
