.
No manned submersible has been to the bottom of the Arctic Ocean.
I'm going backwards down a canyon in a submarine.
It's the most complex terrain I've navigated in.
There's something big dead ahead. What is it?
This is pack ice, this can kill ships.
The wind chill is -8.
If you fall in, you have two minutes left.
'Humankind has explored every continent on Earth.
We've climbed its tallest mountains...
..and even journeyed into space.' Thank you, Mr President.
'But there's a vast swathe of our own planet
that has remained a mystery...
..the deep ocean.
Stretching down over 35,000 feet into crushing pressures,
it's been nearly impossible to reach until now.
New engineering breakthroughs are driving an audacious global mission -
to dive to the deepest points of all the five oceans
for the first time in history.
These pioneers will push technology to the limit...'
What the hell was that? We have a leaking hatch.
'..to open up this final frontier as never before...'
Trying to mentally put yourself at the bottom is mind-blowing.
'..mapping hidden landscapes, discovering unknown life forms...'
What the eff is that?
'..and unlocking the secrets of how life in the extreme deep ocean
affects our entire planet.
Explorer Victor Vescovo is self-funding a multimillion-dollar
daredevil mission to explore the extremes of the deep.'
70% of this planet is covered in the ocean.
Most of the biomass of the world is not in the Amazonian rainforest
or the jungles of Africa, most of the species on this planet
are in the ocean, yet we still really don't understand
how the ocean works.
'On his pioneering global quest
to dive to the deepest points of all the five oceans,
Victor has conquered the Atlantic, the Southern Ocean,
the Indian Ocean, and the Pacific.
But the success of the entire mission now hangs in the balance.'
You've got to do all five.
Like climbing a mountain -
you can't go all the way up except for the last 100 feet
and say you climbed it.
'Victor will fail
unless he can conquer the coldest of them all, the Arctic.
This treacherous ocean envelops the top of our planet.
In winter, around 80% of it is covered in ice.'
From here, it's only a few hundred miles to the North Pole.
We're about as far north as you can get and still be afloat.
There's going to be a lot of anxiety.
A lot of things can go wrong because of the harsh conditions up here.
'Temperatures here can fall to as low -58 degrees Fahrenheit,
and have claimed the lives of many past explorers.'
This is pack ice, this can kill ships.
The ice up here, it's moving and it grows
and it shrinks, it's an unpredictable beast.
If we wait too long, it can actually move south and cover the drop zone.
'The team's target is 170 miles from the Norwegian island of Svalbard.
It's a depression in the Arctic seabed more than 18,000 feet down,
the Molloy Deep, also known as the Molloy Hole.'
No manned submersible has ever been down
to the bottom of the Arctic Ocean.
So I'll be the first person to actually see the Molloy Deep,
which is always exciting, to be the first.
'The Arctic is not the world's deepest ocean,
but amazingly, the slightly squashed shape of our planet means that
if Victor succeeds in diving to the Molloy Deep,
he will be closer to the centre of the Earth
than anyone has ever gone before.
To succeed, Victor has commissioned
a ground-breaking prototype submersible.'
That's good there, perfect.
The world has never seen a vehicle like this before.
This is the first time that humankind
have had a vehicle that can go to any ocean, any depth, at any time.
This is like a spacecraft.
'The team faced extreme cold in the Southern Ocean,
but the Arctic Ocean is even colder,
and will push the submersible closer to its limits.
Its batteries are particularly vulnerable.'
The water temperature is around -1 Celsius.
We've got six lithium batteries on board.
In the back of your mind, you're thinking, "Will they handle this?"
If we lose one, no big deal - we'll keep going.
You know, you start losing two and three -
'The team have finally reached the Molloy Deep.
There can be just a few weeks a year
when the site is clear enough of ice to dive.
They need to make the most of the Arctic's summer's 24-hour daylight
as they scan for the deepest point.'
We use equipment called a multibeam echo sounder.
We use sound, which we send from the ship to the seabed.
It bounces back up, and that gives us a 3-D model of the seabed.
'To survive, the sub will need to withstand pressures
the equivalent of being crushed by the weight of a cruise ship.
But how will the sub cope with the Arctic extremes?
The team have decided to launch an exploratory dive.
The sonar has detected a promising landing zone
at around half the depth of the ocean,
still a crushing 6,500 feet deep.
It's on the slopes of a giant underwater mountain, or seamount.
It was formed from near-molten rock forced up from under the seabed
around three million years ago.
Biologist Alan Jamieson is hoping that
this pioneering dive might also add to the expedition's growing list
of newly discovered deep-sea species.'
The Molloy Seamount is the size of a big mountain.
There's a rain of organic matter coming down.
We're looking at habitats we think will be covered in life.
'Alan decides to launch lander probes onto the seamount.
Baited cameras and traps will help his search for new species
that have adapted to survive.'
OK, Heather, pull it.
'With the lander probes descending,
it's time to launch the submersible into the icy waters.'
Full speed out.
Go ahead and swing her into the pocket.
All right, we're clear. We're ready.
'Biologist Alan will be joining Victor for this trailblazing dive
onto the seamount.'
Don't fall in. The water temperature is -1. If you fall in,
you have two minutes left, then you're going to drown.
Can somebody put some slack on that line? Roger that.
We'll have to see how this looks, boys.
If he has to swim, it's a cold .
You've got to really be mindful.
We do not want him going in the drink, that's for sure.
'Alan and Victor are safely aboard,
but the launch still has potential dangers for the crew.'
One of the people we'll be most concerned with is our swimmer.
He's exposed to the weather most of all.
My biggest risk is, my hands get cold, and they're not much good.
In the Southern Ocean, our diver almost went hypothermic.
Doctor on standby, he's shaking.
He was exposed for so long in extremely cold water on the surface.
Now we have backup divers, a better launch and recovery system.
The danger is to the personnel
trying to get the sub in and out of the water,
that's where I will be most concerned.
All right, Tim. Down to you, buddy.
Out on the tow.
I want you to go full speed out now, full speed out.
Whoa, whoa!
Hang on, buddy, hang on.
All stop. Don't watch my hand, you come on.
Down on the main, here we go. OK, Victor, you're away.
Sub's away, thrusters are isolated.
He's getting his ass kicked out there.
Whoa. Release, release, release.
Hang on, Timmy. Damn!
Released!
I can't see it, so hopefully, it's clear.
Sub is off the tow line. Roger that.
Tim?
Tim? You OK, Tim?
You OK, man?
Kelvin, we have the handrails, we have the swimmer, you're good to go.
Roger that. LF, LF, this is SO.
You're clear to start your dive. Roger that. Enabling thrusters.
'As they begin their descent,
Victor and Alan pass thing sunlight zone.
In the long Arctic summer, the sun won't set on these waters
for four months.
They're home to the acrobat of the ocean, the humpback whale.
These Arctic giants come to feed on the tiny zooplankton
that swarm when the sea ice melts, eating up to 5,500lbs of them a day.
Descending past 600 feet, they enter the twilight zone.
It's home to the graceful sea angel, a type of sea slug.
Its foot has evolved into winglike fins.
And there are visitors from above.
The narwhal. The males have a distinctive, long tusk -
an extended canine tooth which they use to sense prey.
Diving as deep as 4,900 feet,
they can stay submerged for 25 minutes at a time.
Finally, almost an hour after leaving the surface,
Victor and Alan reach the slopes of the underwater mountain.
6,500 feet of water is now crushing them.'
Very rocky.
Approach with caution.
We're going to go down the canyon. Cliff diving, submarine-style.
'Birthed from the fiery depths of our planet,
the seamount's surface is scarred with canyons and sharp ridges.
Could unknown life forms be lurking in this alien landscape?'
Animals living all the way down these cliff faces.
It's just incredibly complex.
It's steep here. Yeah.
The current is pushing me forward. You feel how strong it is? Yeah.
Wow.
What is that?
Whoa - up, up, up.
Up, up, up.
LF, confirm you read my last transmission.
Surface, life support good.
Life support, OK - loud and clear.
It just came out of the sediment cloud.
This current is pushing me all over the place.
Whoa, whoa.
Is it spinning us? Yeah, spinning us up.
Pushing us. We're going backwards down a canyon
in a submarine in the Arctic Ocean.
Whoa!
What the 's going on?
It keeps pushing me into the wall, yeah. Really?
We're going down.
This is easily the most complex terrain I've ever navigated.
It's getting weirder and weirder.
We're stuck on the bottom. What is this?
Yeah, what is this stuff?
There's loads of sea lilies everywhere, wonderful white sponges,
a whole bunch of prawns down here,
there are urchins, sea stars buried in here.
'Meanwhile 2,000 feet away, one of the lander probes
is capturing some extraordinary cold-water specialists - eelpouts.'
They're quite aggressive.
When they get close to one another, they'll have an altercation,
and they'll go and reposition.
These are not a species you find outside of the Arctic,
these are very much a polar, deep-sea species.
'The cold is sapping the submersible's power,
but the batteries have shown that they can survive
the Arctic's extreme temperatures.
It's time for Victor and Alan to head to the surface.'
I guess that's us. That was cool. Three-and-a-half hours.
Surface, this is LF ascending.
Great job, guys.
How was it? Crazy.
We went down a 200m wall backwards cos it was so steep.
The current pushed us up against a wall, so we ended up -
We saw a lot of strange stuff.
We went all the way down to minimal power.
I came up with half my batteries, three were dead. It was cold water.
All right, time to go get warm.
'Victor and Alan found an ocean floor teeming with life forms.
They've evolved to survive in the Arctic depths over millions of years.
The team have some secret weapons
in their quest to uncover the ocean's mysteries.'
Landers are critical to our mission.
They provide a number of major functions.
The first is that they're used for communication
and for navigation of the submersible.
The second is that they're used as camera and lighting platforms
to collect biological data.
Finally, they're used
to bring anything that we might want to collect back up to the surface.
'What scientific treasures have the lander probes
brought up from the Arctic deep?
These amphipods play a vital role on the Arctic Ocean floor.'
Amphipods are scavengers,
they eat pretty much anything that falls from the surface.
You have production events on the surface -
whales and dolphins, squid, jellyfish, even plankton -
organic stuff sinks to the seafloor.
Often, amphipods will be the first animal
to intercept that and consume it.
They turn it into lipid, which is basically fat,
very, very quickly,
then they become high-value prey items to larger animals.
So they might look small and not altogether that impressive,
but actually, scientifically, they are very, very interesting.
Species like this are great to work with
because they're so widespread geographically.
In terms of planet colonisers, that's pretty amazing.
I don't think there's anything in the terrestrial world
that has anything like that kind of footprint.
That's completely different - I have no idea what that is.
That must be an Arctic thing.
I've never seen anything like that.
It's very unusual - that massive antenna,
I've never seen that before.
'And the landers have another surprise.
One of their traps has caught some of the Arctic eelpouts
seen on the underwater cameras.'
The head is kind of transparent, you can see the skull.
These live in perpetual darkness
but they still have eyes because there's biological light -
animals that communicate using light.
They can't see red or green or yellow, they just see blue.
They have this slime on their body.
If you notice, their body, it's that light-brown colour,
but around this area here, it's darker.
That's darker because that's where its stomach is.
That means they probably eat something which bioluminesces -
one of their prey items produces light.
The last thing you want to do, when you're being sneaky in the dark,
is to eat something which glows, cos then you glow.
That's something gelatinous and soft-bodied fish do a lot of
because otherwise they would glow like a light bulb.
The animal itself is quite transparent,
but its stomach has been blacked out
to stop it becoming prey itself to something bigger.
Conditions today are good, but out to the east here, we can expect
5.5 metres, or 20ft seas.
The colour of the diagram shows the wind chill is -8.
So we can expect up to 45, 50 knots.
This part of the world is notorious for rough seas, strong winds.
We just have to be extravigilant, extracareful,
and keep an eye on conditions.
We'll have to condense the diving that we have planned
into a much shorter timeframe.
'Stormy conditions would make launching or recovering the sub
extremely dangerous.
It could also set the unpredictable pack ice on the move.
With the weather holding for now,
the sonar team have detected a strange signal
which could point to an unusual geological feature on the seamount.'
It could be something.
The data that we're looking at from the sonar,
it does show a diffuse cloud,
something erupting on the seabed down there, a vent system.
'Finding the vents could give geologists new insight
into how the Arctic Ocean seabed is being formed.'
It would be such a huge find, to find it.
'It's an opportunity they can't afford to miss.'
Really unusual vent features.
They've never been documented in this area, but indications are
that we'd be able to find them, and that would be a first.
'The sub could now face a new threat -
the Arctic may be the world's coldest ocean,
but the water coming out of the vents could be dangerously hot.'
We're looking at temperatures of erupting fluids of about 90 degrees.
Even 90 degrees C is problematic.
'On the hunt for undersea vents,
the sub could be exposed to dangerously hot water.
The team knows that
the sub's spherical cockpit has potential weak points
that could be vulnerable.'
Hydrothermal vents are about 90 degrees Celsius.
The acrylic viewports would be the thing you'd be concerned about.
The design of the vehicle is based around water temperatures
not being more than 10 Celsius at that sort of depth.
'If the acrylic viewports are melted by the hot vents,
the superhigh-pressure water will enter the sub
and fill it in a millisecond.
To avoid dropping the sub
directly onto potentially damaging hot-water vents,
the team select a landing zone a safe distance away.
Victor will then need to navigate across the precipitous slopes
of the seamount to his target.'
OK, here we go.
'Heather is joining Victor for this 8,200-foot dive
to hunt for the vents.'
I'm so excited!
'She will become the first woman to descend to the Arctic deeps.'
Hatch is good, life support running. I have a green board.
Roger that, here we go.
God, we're almost at 400 already!
We're below the crush depth of most military submarines. Yes!
Oh, gosh!
It's never done that. That's a bad seal or something.
That's way too much.
Surface, LF. We've got dripping coming from the hatch.
The main hatch? Hatch vent. I repeat - hatch vent.
I'm calling an abort.
Dropping VBTs and surfacing weight, returning to surface.
I understand - dropping VBTs and surfacing weight.
I'm not pleased.
We need to rally our troops.
Can you go into the lounge and let everybody know? Rig for recovery.
Disappointing that he's coming back up.
We'll go to the recovery, have a look.
Maybe there's something in there, I don't know.
I'm going to shift my gear off,
jump up there and pull that vent out right away.
'With the approaching Arctic storm threatening to curtail the mission,
sub engineer Kelvin is under pressure to get the sub fixed
and back in the water as soon as possible.
The sub won't be able to dive again
unless Kelvin can fix the hatch vent.'
This is where the leak was coming through.
We think the shaft might have been bent a little bit, which it is.
We're just going to try and straighten it out.
I don't know whether it was dripping a little or a lot.
'With such a precisely engineered component,
there's only so much Kelvin can do in the ship's workshop.'
It's not going to straighten up in there, there's a variance.
'Has Kelvin done enough to make the hatch vent seal?'
A little bit of backyard mechanicking.
Patrick, that felt really good. All right, Kelvin.
That's all we can do.
'With a turnaround of just over two hours,
the team can now launch again to search for the underwater vents.'
Let's hope like hell that hatch vent works.
Round two. If at first you don't succeed -
Good luck, have a good dive.
OK, bridge, we're going to go for a launch.
Copy that, you are good to go. We are pumping in.
Roger that, you're good to pump. Pumping.
That hatch is looking damn solid now, I'm much happier.
Surface, hatch is good.
Good to hear. Thanks, Victor.
Kelvin will be happy.
That was it, Magee. Yeah!
'After 25 minutes of descending,
Victor and Heather reach the midnight zone.
Only 1% of sunlight penetrates the 3,000 feet of water above them.
Temperatures this deep are below 0.
It's only the salt in the water that keeps it from freezing.'
Surface, LF. Present depth, 1-niner-2-1.
Heading 0-2-2. Life support, good.
'This is the domain of the mysterious Greenland shark.
Growing to 21 feet,
it has one of the longest lifespans of any animal on earth -
it can live a staggering 500 years.
Some alive today may have been born before the voyage of the Mayflower.'
Here we come.
Touchdown.
You're getting excited, you're using more oxygen. Am I? Sorry.
It's true. I saw the oxygen spiked up since we got to the bottom.
Look how sharp it is down there.
All these rocks look really dark and basaltic.
There's another big basalt rock coming.
'Basalt is formed from solidified lava
which erupts as the bedrock pulls apart.
Could this be a sign that the hydrothermal vents,
with their potentially dangerous hot water, are close?'
Pretty big boulders off to your left.
Boulders the size of cars scattered all over here.
Looks like something quite large coming up,
you might want to lift up a little bit.
Definitely something very big. Something big dead ahead.
What is it? I can't see.
Wow.
'6,200 feet down, the sub has run up against a huge obstacle.'
I don't even know how high that is. Yep, no idea.
That is massive. Right in our way.
We're going up a really sharp incline.
Looks near vertical now.
Wow. Jeez!
It's pushing me backwards, it's pushing me down the slope.
I need you to help me out here. Yeah.
This is pretty dynamic. Coming up quick on this side.
Whoa!
Where did he come from? That happens, once in a while.
I'm totally going into that big, black, open area.
Ho-ho! Why don't you drop off on that side?
Wow.
Like space exploration, huh? Yeah.
Like a different planet.
Those nodules on the bottom, are those critters?
Those are interesting. Oh, yeah, yeah.
Very different to what we were seeing
coming up the steeper sections there.
We've got some stuff coming up, look at the centre.
Oh, yeah.
Which is interesting, because this is all flat sediment. Yeah.
Yet we've got a big God-knows-what coming up.
This is different.
It's undulating, like we're on the top of a mesa.
Look at this. That's a hard crust.
I've never seen that. A hard crust of some sort.
Oh, my God. See? Look.
I was just... Yeah. There's a tunnel!
How does that happen?
'The crust that we're seeing is
showing us that there's fluids coming up.
It's depositing the minerals
and gluing together the softer seafloor sediment,
and forming this hard crust.'
'This new evidence for fluid emerging from the Arctic seafloor
is a groundbreaking find,
a secret, dynamic landscape revealed in the Arctic deep.'
There's another one.
Oh, wow!
There it is!
She's pretty happy.
How was that? Thanks, guys. Just amazing.
I'm glad we finally got you down. Yeah.
'Victor heads to the sonar room
to discover if there's news of the team's quest
to find the deepest point in the Arctic,
the final goal of his global Five Deeps mission.'
We identified this area to be the deepest, we'll dive here.
We have a lander on the deepest spot.
That's it, right here.
'Victor's target is in the shadow of the seamount,
more than three miles down.'
This is the first time that anybody has dived at this site.
That makes it exciting, but it also means you have to be careful.
'The sub's systems will need to survive in the Arctic danger zone
for more than seven hours.'
She looks clean.
It's going to be the coldest dive, no doubt.
That'll add a lot of stress to the submersible,
to the electronics, the sphere, everything.
'With the team preparing for the deep dive,
the weather window is closing.'
I think the weather is going to turn on us,
so it's going to be a push.
We want to get that dive done, but we're fighting weather again.
The low-pressure system which is forming south of us
is throwing weather up towards us.
That's going to push the pack ice onto the dive site.
'The team must launch as soon as possible.
Everything hinges on this crucial dive to the last of the Five Deeps.
This is Victor's chance to mark a new chapter in human history,
as the first person to reach the deepest point
of all the world's five oceans.'
The last push to get across the finish line.
It's so tantalisingly close, yet we're not there.
OK, Victor, your chariot awaits.
Nice one, buddy.
Thank you.
Number five, let's do this. One more!
Let's do it.
All right, Kelvin - put him in and bring him back safe.
You betcha.
It will get colder, I have no doubt.
You're clear to start pumping. Roger that. I have a green board.
'It will take Victor more than 2.5 hours to reach the bottom.'
There she goes.
'The lander probe CLOSP has been dropped on the deepest point
identified by the sonar team.
Victor will need to navigate across the seabed to CLOSP
to complete his Five Deeps mission.'
25 metres already. This machine goes down the water column pretty fast.
Wow, this is exciting.
Last of the Five Deeps, such a long journey.
I'm in the deep, dark, black ocean.
A little crack here and there.
It's just the outside of the submersible
getting used to the pressure.
That's always a little alarming.
The temperature is dropping despite the heater.
Surface, LF. Present depth - 3-3-0-0. Life support good.
Roger, LF, loud and clear.
Roger.
Definitely two thirds of the way down.
Getting close, wow.
'The pressure squeezing the sub has increased
to a staggering 30,700 tons.
There's the equivalent of 1,031 storeys of water above him -
ten Empire State Buildings stood on top of each other.'
Getting a little drop of water from the hatch vent.
It should seal with the higher pressure, to be honest.
'Victor Vescovo is diving to the bottom of the Arctic Ocean,
but now water is finding its way through the hatch vent.
As Victor descends further,
the sub is squeezed by the immense water pressure.
Amazingly, this begins to plug the hole.'
That's pretty much stopped, that's good.
I'm not concerned, that is not an abort condition.
'Two hours into his descent, at 13,000 feet,
Victor enters the abyssal zone, the deepest part of the Arctic Ocean,
and home to an Arctic variety of the deepest-living octopus,
the bizarre dumbo.
While most octopuses swim using jets of water,
the 9"-long dumbo propels itself with its earlike fins.'
There it is - 5,000 metres.
Oh, my goodness, this is getting exciting.
So close.
All external lights are on.
Sonar is on.
143 metres off the bottom in the last of the Five Deeps.
Here we go, we're getting close.
Oh, my goodness. We should start to see it very soon.
I'm at the bottom of the Arctic Ocean.
Surface, this is the LF. The LF has landed.
That's great.
He's not going to talk any more, he's going to navigate to CLOSP.
'Victor is the first human being to reach the bottom,
but the mission isn't over -
he still needs to reach the deepest point of the Arctic Ocean.
The lander probe named CLOSP has been dropped at this location.
If Victor can find it,
he'll complete his record-breaking Five Deeps mission.
If he fails, his dream will remain beyond his reach.'
Roger, LF. Searching for CLOSP.
There's some little creatures on the bottom, quite a few.
I'm getting a lot of violent variation in my heading,
it's all over the place.
I'm wondering if the magnetic field of the Earth this far north
is playing havoc with my navigation system,
giving a lot of erroneous readings.
LF, surface.
LF. Go ahead.
The lander is approximately 200 metres.
I've got a hard return dead ahead.
I don't see his light, just too far out.
Going due north.
He must be getting close.
Come on. OK, I'm getting slightly away.
I'll try south again.
Surely he's got it on sonar.
, damn - 121 metres.
All directions can't be farther away from you.
Searching for CLOSP.
Roger, LF -
searching for CLOSP.
'The clock is ticking.
Victor must find the lander probe before the cold of the Arctic deep
depletes his batteries.'
OK, closing. It is north and east of me.
No, a little more east.
CLOSP. No matter what I do, I go farther away from it.
It's now south of me. That's my skid marks there.
'With his instruments malfunctioning,
Victor is struggling to find his way in the abyss.'
Very silty.
If you blast the surface, you've really got to move to get out of it.
I just cannot get a good - More north or more south?
Oh, that's got to be him.
I've got a really hard return.
Come on.
He's at the right depth.
Present depth, 5-5-8-9. Life support, good.
Roger, LF. We have you loud and clear.
Surface, LF. Present depth, 5-5-8-9.
He can't hear us. He can't hear us.
'Victor's precious link to any help from above has cut out.
He's now completely alone.'
Did he get your message? Not sure. No, he didn't.
.
'With no link to the sub, mission control are powerless
to help Victor with his time-critical search.'
Can't hear them at all.
Come on, I'm almost out of time. It's almost three hours down here.
Come on!
Ah - 23 metres.
I have you now.
I gotcha.
There it is, the end of a dream.
I have to touch down.
I'm at the bottom of the Arctic Ocean.
Surface, this is LF.
Life support good. The LF has landed at CLOSP.
Roger that. You are on the bottom. Congratulations.
Thank you, sir, and thank you, all.
All of you made this happen. Thank you so much.
Woo-hoo!
Hell of a thing. Patrick, we did it.
Five Deeps, done. Let's go home.
I've just completed the Five Deeps.
This is the first submarine, and I guess I'm the first person
down to all five of the world's oceans.
It's incredibly exciting, I can't believe we were able to do it.
What an amazing machine.
'On its 46,000-mile, round-the-world odyssey,
the sub has proven a triumph of engineering,
conquering the most extreme underwater environments
on the planet.
Victor has overcome adversity in the depths of the Atlantic...'
Oh! Oh, my God.
We just lost the manipulator.
'..conquered the extremes of the Southern Ocean,
found new species in the Indian Ocean's tsunami hot spot...'
I've never seen anything like that.
'..and gone deeper than any human
in the depths of the Pacific's Mariana Trench.'
Victor Vescovo, world's deepest diver. Woo! You did it, buddy.
Yeah, five!
Well done. Lovely job, sir.
Hey, buddy. Well done. Right on.
'I'm so proud to have been part of this historic expedition.
For me, it's been the privilege and honour of my professional life.'
Well done.
Congratulations, man. Congratulations to you.
You built it. So proud of you. Thank you, Shane, well done. Awesome.
Scientifically, it's been absolutely amazing.
