There are human footprints on the moon.
and Rover is exploring the surface of Mars.
We can Google a satellite picture
of any place on the Earth's surface.
So we often think that our planet
has been completely explored.
But the depths of the oceans remain a mystery
and the extreme depths
have barely been glimpsed.
Down there is the last great frontier of our world.
There are 12 trenches that are over 4 miles deep.
They're thousands of miles long
and have a combined area greater than North America.
That's a dark continent down there, waiting to be explored.
Unseen by human eyes because the machines don't exist to take us there.
It's my dream to build such a machine,
and get inside it
and dive to the deepest places in the world,
to explore them with my own eyes.
I started preparing for these dives when I was a kid,
getting in a cardboard box.
Close the lid, and imagine it was a submarine.
Drawing with a crayon, you know, some gauges.
Yeah, I was a real science geek, you know,
but for me it was all about trying to understand the world,
understand the limits of possibility.
Hey, little buddy.
I think it was from being a kid in the'60s
when we were doing so much exploration.
From going to the moon and Jacques Cousteau was exploring the oceans
and, you know, I just loved that stuff.
I couldn't think of anything cooler than to be a deep ocean explorer.
I can remember the first time that the deep ocean captured my imagination.
It was, you know, when Trieste went to the bottom of the Challenger Deep.
The Bathyscaphe would pass its ultimate test in 1960,
its third model carrying Piccard's son, Jacques, and Don Walsh
35,000 feet down into the Mariana Trench.
The Bathyscaphe Trieste was an amazing machine for its time.
A massive 150-ton steel balloon
filled with gasoline for flotation.
It had a 14-ton pressure sphere
for the crew slung underneath.
Oxygen, one thin bar.
Scrubber fans on.
Tachometer's taken a hit.
We go without it.
Inside the sphere,U. 8. Navy Lieutenant Don Walsh
and scientist Jacques Piccard
would pilot Trieste to the bottom of Challenger Deep.
It was a dive into history.
But no one has been back since.
Just like on Trieste,
the heart of our new sub is a steel sphere,
forged in fire.
52 years later, there's still no better solution.
The sphere is nature's perfect shape for resisting pressure.
And it's going to protect me from the crushing force down at the bottom.
Over 16,000 pounds per square inch.
That's like having two Humvees stacked on your thumbnail.
it's taken us three years to design and build this sphere.
We have to heat treat the steel...
to be strong enough to withstand the weight
of seven vertical miles of water.

We have to know that the sphere is safe.
If it buckles on a real dive,
it'll implode at hypersonic speed
and I get chummed into a meat cloud in about two microseconds.
The clinks I heard when we tested it the first time,
when we got rid of the stress cracking, that hasn't happened.
It's 16,000 psi.
Looks like we've done it.
Yeah, you got to be happy with that. We're all the way to the top.
-So, it's as you predicted? -It's as we predicted.
-做得好 -你真行 羅恩
-Well done. -Good on you, Ron.
When you design technology to do something new,
it's going to look strange.
The Deepsea Challenger is a vertical torpedo.
it's designed to scream down through the water column at high speed.
The reason for that is we’d just rather spend the time at the bottom
working, exploring, than going through seven miles of water.
There are certain fish that actually will hover
over the reef in a vertical position.
So, nature provided an example
of the fact that it's not crazy to think that a submersible
can move through the water in an upright position.
Deepsea Challenger is not a stunt vehicle
to just go down and set a depth record.
it's designed from the ground up as a science platform.
There's a hydraulic manipulator arm for taking samples.
A sample tray in the science door.
There are push cores for taking sediment.
A payload bay for instruments.
And two 3D cameras,
one on the boom and one on the arm.
Every single thing on this vehicle has to be built from scratch
to withstand the crushing pressure.

it's just this kind of ragtag group
working in this little tiny shop
next to a plumbing supply place on that side
and a plywood supply place on that side.
You know, nobody even knows what we're doing in here.
And one of the most amazing things about this vehicle
is that it shrinks over two inches during the dive from pressure.
That's enough to shear aircraft grade bolts.
Yeah, it's still got to go in quite a way.
So the sphere is actually held on to the sub by straps.
But we're also fighting the pressure of time.
Our expedition ship just arrived
and we're supposed to leave in less than three weeks, but we don't have a sub.
it's still in pieces all over the shop.
How big a problem is that?
I need to know when we're going to see some action on that sub,
so we can start doing some integration.
If you're saying 3rd of January
we're going to have it wired out,
we're still weeks away from getting integration done.
We have to have an integration schedule.
I want that schedule put up on the wall right over there, okay?
Who's got to have their stuff plugged in, ready to test, when.
And everybody is going to be individually accountable for their stuff to that schedule.
We've got a ship sitting at that pier down there with nothing to do.
