The greatest conquests of mankind are the conquest of the Moon, Everest, the Mariana Trench, and the drilling of the Kola superdeep well.

Of course, the conquest of the moon, like space flight in general, can probably be called the highest achievement of the human world - "a small step for man and a giant leap for all mankind." This is the most distant place that a person's foot has stepped on.

On July 21, 1969 at 2 hours 56 minutes 20 seconds GMT, the famous American astronaut Neil Armstrong first set foot on the moon. Buzz Aldrin followed him 15 minutes later. In total, both spent 2 hours 31 minutes and 40 seconds on the satellite. This time was enough to plant the long-suffering US flag on the moon (which became almost the main argument in favor of the conspiracy theory that the Americans were not on the moon; read more about this in our material "The most famous conspiracy theories"), install scientific instruments and take soil samples.

In total, in the entire history of mankind, 12 earthlings have visited the moon - all of them were astronauts of the Apollo program.

Mariana Trench

This is the deepest place on Earth, or rather in the ocean, was visited by only three people in history (as we can see, fewer people have visited the Moon).

For the first time, US Navy Lieutenant Don Wash and explorer Jacques Picard descended to the bottom of the Mariana Trench in the Trieste bathyscaphe, designed by Jacques' father, Auguste Picard. The dive took place on January 23, 1960.

After that, only automatic underwater vehicles sank to the bottom of the Mariana Trench. And only on March 26, 2012, the brave adventurer filmmaker James Cameron once again visited the deepest place on the planet, becoming the first person to do it alone. Reaching the "Challenger Abyss", which is at a depth of 10,908 meters, Cameron took samples of rocks, living organisms and filmed the depression.

Everest

The first people to conquer the highest mountain on the planet were New Zealander Edmund Hillary and Sherpa Tenzing Norgay. It happened on May 29, 1953. They spent only 15 minutes on the "roof of the world".

Kola superdeep well

Until 2008, it was considered the deepest well in the world. It is located in the Murmansk region, not far from the town of Zapolyarny. Its depth is 12,262 meters, the diameter of the upper part is 92 cm, and the lower part is 21.5 cm. All other superdeep wells were drilled with an exclusively pragmatic purpose - oil production or geological exploration. The task of the Kola Superdeep (or SG-3) was strictly scientific. With the help of this well, scientists examined the crust of our planet, because the well was drilled exactly in the place where the so-called Mokhorovich boundary (the lower part of the earth's crust) comes close to the Earth's surface.

The Kola well is often called "a well to hell". There is a legend saying that when the well was being drilled, at a depth of 12 km, people could hear the screams and groans. This, of course, is a myth, however, while drilling a well, some phenomena still occurred, explanations for which have not been found so far.

For many years, the "well to hell" did not receive financial support from the state, and in 2008 it was decided to mothball the facility: the well was welded, the equipment was dismantled, and the building for its maintenance began to collapse.

In the same 2008, the SG-3 record was broken by the Maersk Oil BD-04A oil well (12,290 meters), and in 2013 by the Z-42 well of the Chayvo field (12,700 meters).
