Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery.

Today you learn with the Perseverance Rover taught us about the Jeziro Crater on Mars

and how augmented reality could help people

cure their fear of spiders.

Let's satisfy some curiosity.

When NASA chose Jeziro Crater as the landing site for the Perseverance rover, they did it for a good reason.

Scientists had seen hints that this dusty canyon was once a massive lake.

And where there was water, there may have been life.

Perseverance has been taking pictures of its surroundings since it landed in February,

and scientists think that these pictures show conclusive evidence that Jezirocrator was indeed a huge body of water, and one

with a pretty dramatic past.

Here's why scientists thought Jezirocrator might have been a lake.

Running water, like in the flow of a river, carries silt along for the ride.

When a river meets a lake, all that silt builds up into layers of sediment in a distinctive fan shape.

Scientists recognize this fan shape in parts of the Jeziro crater from images captured

in orbit around the planet.

So, perseverance went to investigate.

The new images from Perseverance showed details of the sediment.

Because of the layering and the slope of the outcroppings,

scientists concluded that they were formed by flowing water rather than wind or another geological process.
