Located in the northwest 
Pacific Ocean, within the 
oceanic depression known as 
the Mariana Trench, it is the 
deepest known point in the 
world: the Challenger Deep. It 
is one of the most mysterious 
and inaccessible places of the 
planet, being situated at 
10,902 meters below sea level 
and about 2000 meters above 
the height of Mount Everest. 
On 23 January 1960, the 
oceanographer Jacques Piccard 
and the lieutenant Don Walsh, 
on board the bathyscaphe 
Trieste, achieved to reach 
this unknown darkness. The 
descent took 4 hours and 48 
minutes while the ascent to 
the surface took 3 hours and 
17 minutes, a period of time 
that was well defined, but 
they perceived it as an 
eternity. The two men remained 
on the ocean floor for about 
twenty minutes during which 
the bathyscaphe was subjected 
to a pressure of a thousand 
times higher than that 
recorded on the sea surface. 
They thought life there in 
total darkness couldn't be 
possible. Turning on the 
lights of Trieste bathyscaphe, 
however, they were very 
surprised to see through the 
porthole a shrimp and a 
particular species of sole, 
wandering in a desert of white 
sand. The piece describes this 
legendary expedition through 
four sections that follow each 
other seamlessly: "The Ocean" 
depicts the vast expanse of 
the sea, "The Mariana Trench" 
the descent into the ocean 
trench, "Abysses" the dark 
depths of the sea, "Towards 
the Sky" the ascent to the 
surface in the sunlight. A 
fearless and extraordinary 
feat which has never been 
repeated. Man climbed 
thousands of times on the 
summit of Everest, six times 
he has set foot on the moon. 
Piccard and Walsh, however, 
remain the only human beings 
who have reached the farthest 
point of the earth, the 
Challenger Deep.
