The second alternative would be to use injection piles.

Shall we go see the dunes?

The beautiful thing is that it moves bodily.

As I said earlier, it looked very much like Earth, so you see sand dunes.

It adds roughness to the dune's surface, to the texture of the dune's surface, binding the grains.

In a desert plain in Tanzania, in the shadow of the volcano Ol Doinyo Lengai, there's a dune made of volcanic ash.

This is where the village used to be.

If you want to see the dunes, Dr. Chapuis is going.

Yesterday, you promised we would go see the dunes together.

I was told you are going to the dunes and as I missed the bus ....

OK, so this is our movie of the equatorial region of Titan, showing these dunes.

And you can notice they have created a kind of false catchment.

They love Namibia for its beautiful dunes, that are even taller than the Empire State Building.

It has taste like cat feces.

It's what's technically known as a barchan, and the entire dune walks across the desert in a westerly direction at a speed of about 17 meters per year.

Everyone in the class climbed the hill.

We can start harvesting condensation, and start greening the desert from within.

Just like John Wayne, we ride up over the hill, huh?

What happens is that the wind blows the sand up the shallow slope on the other side, and then, as each sand grain hits the top of the ridge, it cascades down on the inside of the crescent, and so the whole horn shaped dune moves.

But before I do, I just want to mention that this animal truly is a sort of the SUV of the sand, the ship of the desert.

These hills swarm with our scouts.

Just give me something without any sugar in it, okay?

Give us back our hills!

like pink garnet and green epidote, all kinds of amazing stuff, and if you look at different sands from different places, every single beach, every single place you look at sand, it's different.

So, we pushed the piles down through the dune, and we create an initial bacterial surface.

(Video) Virtual Choir The evening hangs beneath the moon A silver thread on darkened dune With closing eyes and resting head I know that sleep is coming soon Upon my pillow, safe in bed, a thousand pictures fill my head I cannot sleep my mind's aflight and yet my limbs seem made of lead If there are noises in the night

Coast is clear, guys.

This is the Saharan desert of Titan.

Like crazy far, so just keep heading down that dirt road for like what?

They're outside. They said they're going to throw us into the Deadly Desert.

The threat is desertification.

In the hills?

This femur is like a wet bag of gravel. The other one's not much better.

We could hear footsteps crunching through the gravel.

I saw the hill.

I found him on the hill...

The bottle was filled with what looked like sand.

Some of those grains may then accumulate on a massive scale, into a sand dune.

He likes coffee without sugar.

Let's get back to the town and walk to the site.

Gold!

My house is on a hill.

I don't know any ObiWan... but old Ben lives out beyond the Dune Sea.

Not that I remember.

We came in sight of the hill.
