To keep my business ahead of the game, I knew I needed some fresh ideas and fast.

That's why I decided to host a young person on a tea level industry placement.

My student has already brought loads of new skills into the workplace.

Plus, we're getting first pick of new talent coming into our area of business on a local level.

It's been a total win-win.

Go next level with tea levels.

Here's John Batchler.

3.4 billion years ago in our solar system, an asteroid strikes the Northern Hemisphere of Mars.

The Northern Hemisphere known as Krishaplanisha.

That asteroid strike leads to events that are a window on the history of Mars, planetary geology.

3.4 billion years later, in July 20, 1976, 46 years ago,

an alien spacecraft from the planet Earth lands in the zone that allows us to imagine what happened the day of the asteroid strike.

This, of course, was the landing of Viking I.

NASA's maiden entry into the surface of Mars, which we now explore with rovers and orbiters.

However, it turns out that Viking landed in exactly the place that we get to explore Mars.

And we welcome Professor Alexis Rodriguez, who with his colleagues publishes a paper at Nature Research.

This is Nature magazine that peer-reviewed top of the pile for science magazines in Europe.

The title of the paper tells the story that Professor will help us understand.

Evidence of an oceanic impact and megatsunami sedimentation in Krishaplanisha Mars.

Professor, a very good evening to you.
