Mars 3 arrives to a dust-shrouded planet
Mars 3 arrives to a dust-shrouded planet When the Russian orbiter Mars 3 arrived at Mars late in 1971, it found the surface of the planet to be almost completely obscured by an enormous global dust event. Several months later, the sky was finally clear enough to reveal surface features. The image on the left was captured on December 12, 1971, and the one on the right on February 28, 1972.
