Finding the Canals of Mars
Mars is a small planet never closer to the Earth than 35 million miles (56 million kilometers). That makes it difficult to see surface details.
When his report of the channels was translated into English, these 'canali' were mistranslated into canals. Canals are not a natural phenomena and this unfortunate mistake seemed to point to the existence of a Martian civilisation.
Canals of Mars
Mistranslation - and consequent misunderstanding - of an Italian description of the pattern or channels (canali) on the Martian surface.

Second, "canals" and "seas" cover the entire planet. The canals may have been waterways many millions or billions of years ago, but they are now dry, as are the seas. The seas were probably oceans that covered parts of Mars.

Martian 'canals'
Map of Mars by Giovanni Schiaparelli
By the 19th century, the resolution of telescopes reached a level sufficient for surface features to be identified. In September 1877, a perihelic opposition of Mars occurred on September 5.
The Martian Canals When early astronomers trained their crude telescopes on Mars, they could see few details of its surface beyond some dark patches and white polar caps. In some ways, the mysterious planet seemed tantalizingly like Earth.
semicircular canals Structures of the inner ear, the primary function of which is to register movement of the body in space. They respond to change in the rate of movement.
He founded the Lowell Observatory in Arizona (1894), where his studies of Mars led him to believe that the linear markings (first noted by Schiaparelli) on the surface were "canals" and therefore that the planet was inhabited by intelligent beings.

The American astronomer Percival Lowell then popularized these faint lines as canals and held them out as proof of a vast attempt by intelligent beings to irrigate an arid planet.
Unlike early somewhat fanciful reports from astronomers viewing the moon, no canals, and certainly no advanced lifeforms are present on the surface of Mars, but the presence of microscopic organism have not been ruled out.

INTERLUDE 10-1 Martian Canals?
The year 1877 was an important one in the human study of the planet Mars. The Red Planet came unusually close to Earth, affording astronomers an especially good view. Of particular note was the discovery, by U.S.
Of course, if there are canals then someone (or something) must have built them! Oh, dear, many people thought, there may actually be Martians! ...
oculogyral illusion (NASA SP-7, 1965) The apparent movement of an image in space in the same direction as that in which one seems to be turning when the semicircular canals are stimulated.
Lowell studied Mars extensively, especially its surface markings, which he thought were canals. He also thought that the bright areas were deserts and the dark ones were areas containing vegetation (this was not true).
All that was revealed was a surface containing many craters and naturally occurring channels but no evidence of artificial canals or flowing water. Finally, in July and September 1976, Viking Landers 1 and 2 touched down on the surface of Mars.
The question of the presence of life on Mars has been an essential element of general discussions of the planet since Schiaparelli first included an interconnecting system of "canals" on his maps of the planet.
This was then badly retranslated into English as canals, and the idea of an intelligent race of Martians building a huge canal system to save their planet from desertfication became popular.
After Percival Lowell established his Flagstaff observatory and published three books on Mars, its canals and supposed inhabitants, he turned his attention to the outer planets.
Giovanni Schiaparelli (1835-1910) was an Italian astronomer (and director of the Milan Observatory) who first mapped Mars (in 1877) and brought attention to the network of "canali" (Italian for canals or channels) on Mars.
" Percival Lowell, then a leading authority on Mars, created a long-lasting controversy by accepting these "canals" to be the work of intelligent beings.

Schiaparelli described some of the line-like features he saw as "canali," or channels, but the word was translated into English as "canals," implying that they were created by Martians. The idea of the Martian canals persisted into the mid-1900s.

Purcival Lowell is well remembered for misinterpreting linear surface features as canals used by Martians for irrigating crops. Seasonal color variations were once thought to indicate lichen, moss, algae or some other form of plant life.

Even with large telescopes it is very difficult to see detail and many experienced observers were deceived into thinking that they had glimpsed features, such as the infamous canals, that in fact were not there.
