Fink said he was going to miss his family back on Earth, of course, but that it was awesome to get to celebrate with what he called his space family.

Since the 1970s, scientists have thought that swirling dust on Mars might produce some kind of electrical discharge.

Like on Earth, clouds of turbulent volcanic ash can create lightning.

Now, in the journal Nature, a team says that in windy conditions, a microphone on NASA's Perseverance rover sometimes did more than just hear wind.

Dozens of times, it registered a distinctive pattern of electrical interference followed by the acoustic signal of a shockwave.

They say this had to have been from electrical arcs just a few centimeters long.

They want to learn more about this electrical activity to understand what risks, if any, it might pose to future human or robotic missions.

It's hard for a young would-be queen ant to strike out on her own and try to establish a brand new colony.

So some ant species have evolved a way for female ants to basically take over existing colonies of another species.
