• NASA Just Detected Lightning on Mars
For decades, scientists weren’t sure if Mars could even produce lightning. The planet has no global magnetic field.
No thick atmosphere.
No storms like Earth.
But NASA’s MAVEN spacecraft found something incredible. A signal called a “whistler wave.”
On Earth, these signals are created by lightning. They travel along magnetic field lines through a planet’s ionosphere.
And out of more than 108,000 measurements…MAVEN detected exactly one.
A 0.4-second electromagnetic signal. Up to 110 hertz. Perfectly shaped like lightning.
So where did it come from? Scientists think Martian dust storms may create electric charges—
Just like volcanic eruptions on Earth. When dust particles collide…
They build up electricity.
And sometimes…
They discharge.
Mars doesn’t have a global magnetic field. But it does have localized crustal magnetic patches—
Especially in the southern hemisphere. If the magnetic field is perfectly aligned… And if the ionosphere conditions are just right… A lightning discharge could create a detectable whistler wave.
That’s why it’s so rare. Out of 108,000 chances. It happened once. Meaning lightning on Mars is possible.
Just incredibly hard to catch.
