re: Speaking of winds...
A 300 mph [hypothetical] wind on Mars would be equivalent
to roughly a 30 mph wind on Earth.
The equation used is:
D = atmospheric density of Earth's SL atmosphere.
d = ground level atmospheric density on Mars [Av]
V = wind velocity on Earth.
v = wind velocity on Mars.
V^2 = [d/D] x v^2
A 30 mph wind on the Earth wouldn't blow over a well-stabilized
MER rover.
