mars surface dust storm

Global storms on Mars launch dust towers 80 km (50 miles) into the sky

When a massive dust storm on Mars-- like the one in 2018-- reaches its full potential, it can transform into a globe-bestriding colossus. This happens often on the red planet, and these storms typically start out as a sequence of smaller storms. NASA scientists said...
