Ben Bova: Mars (1992)
“The analogy between Mars and Earth is, perhaps, by far the greatest in the whole Solar System.” This sentence could be found in any modern textbook on astronomy or planetology. However, these words were written by the German-born Englishman William Herschel in 1783. At that time Mars was in favorable opposition, and the anglicized German musician and astronomer observed the planet with his self-made 6-m telescope with a 47-cm mirror.
