Comments on Snowboarding On Mars? Heinlein Was Ready
How long ago did Robert Heinlein write about skiing on dry alien worlds? (Read
the complete story)
| "I wonder if this also explains the "canals"? Really large blocks of dry ice sliding across the countryside, driven by the wind instead of just gravity. And when the next storm goes by, the canal is erased, explaining why they appeared and disappeared." (Ashley 6/13/2013 7:30:46 AM) |
| "As far as I know, the Martian 'canals' were the result of early drawings of the red planet by Italian astronomer Giovanni Schiaparelli during the opposition of 1877. He called these apparent straight line features 'canali' , translated as canals in English. Subsequent high resolution pictures show the 'canals' are an optical illusion."
