It was amazing. These giant chimneys, huge giant chimneys.

And that's a picture of me in front of it for scale.

Robotic rover

And so at last mankind began the conquest and colonization of deep space.

We see that there is nothing left open and now, we're really done. Ta da.

This is the target site, the world's deepest hydrothermal spring at Cenote Zacaton in northern Mexico.

Light detection and ranging.

Attention, robot probes!

What do you see coming up?

Now, assume we search from left to right.

I'll have activated the holodetector. Now, hurry.

Well you may see the impact already now.

So, we believe that on Europa there is, in fact, a deep ocean.

We have a device.

I mean, I cut through three years of engineering meetings, design and system integration, and introduced DEPTHX

When is it worth exploring to try to find something better for the long term even though we know that exploring is going to hurt us in the short term?

Send a robot probe!

The third problem is that many states recur in the search.

How many nodes would we now expand in Breadth First Search, and how many do we expand in Depth First Search?

But we launch plutonium batteries all the time.

Because one of the things that's frustrated me as a deep sea explorer is how many animals there probably are in the ocean that we know nothing about because of the way we explore the ocean.

Dradis sweeps indicate it's time to break out the swimsuits... because we've found water!

The goal is to protect biodiversity, to provide stability and resilience.

Locate this customs agent, this J. Murphy.

Here we have Juno on its cruise to Jupiter, there.

Tremendous and beautiful discovery.

An imperial probe droid.

Now he's in this state, but notice that this state is symmetric to this one.

It's operating on the International Space Station.

So one of the tools that we use to sample the deep ocean are remotely operated vehicles.

In other words, we'd have to stop exploiting the best policy we'd found so far which is this one and start exploring, to see if maybe there's a better policy.

And we stole recently a ship from the United States Navy.

But that leaves a real riddle.

United Planets Cruiser C57D...

Actually, I was looking for Agent Gibbs.

Deepsea marinelife exploration.

Well, from what the boss said, I gather you're working on the secrets of evolution or something like that.

No, no, that's the only place a ship's been.

I've been told Vulcans have never been explorers.

I thought that was a great idea of NASA, and I think it's a great idea for lots of applications.

Now, no one will argue that we don't have robots.

Now we have to get through the ice.

Let's run that last sweep again.

Now the question is with this description of this problem can we achieve the goal?

And the final robot I'm showing you here. This was built with my colleague Will Whittaker at Carnegie Melon University.
