Question: Have you discovered anything amazing/shocking about how our planet works?

Hi!

Not me personally, since I build the spacecraft but don’t usually work with the data they create. There’s whole teams of other scientists dedicated to that!

But I do read about what is found. I personally learning about the magnetosphere of the Earth – the magnetic field around the planet that is responsible for so much, including keeping us alive, our atmosphere intact, the Aurora, helping satellite orientation and, of course, our compasses when we get lost!

And then to thing that that field is created by huge amount of molten iron lava spinning under our feet, half way to the core of the planet…
