Kinematic viscosity measures the rate at which momentum diffuses through a fluid. Wasn't expecting it to be higher on Mars.
It's not very sensitive to pressure, so must have to do with the low mean temperature, the high CO2 content, or both.

I was also very surprised that the kinematic viscosity would be bigger in Mars and that's why I checked.
The dynamic viscosity on Earth is still about two times bigger than on Mars.

Glad you enjoyed them! As you can see, I'm totally obsessed at this point.
You didn't see Martians because they all moved to Titan when they saw us coming.

Can't get a ride like that at Disneyland.
