THE WEATHER ON MARS

The Curiosity rover on Mars continues to return fascinating new discoveries. Recent data on the Martian atmospheric pressure and wind measurements have been sufficiently sensitive to reveal daily variations in radiation levels linked to changes in air pressure.

There has been some damage to one of the wind sensors, probably occurring at the landing on the surface of Mars, but it has been possible to work round this problem.
This mobile science laboratory on Mars is an amazing tool, under such sensitive flexible control from Earth.
