The Martian Canals
The Planet:
Mars is the 4th planet away from the Sun in our solar system. As our neighborit shares many similarities of earth. It has ice caps, volcanoes, storms andseasons. As the technology of astronomy has progressed, mankind has beenintrigued by the surface features of Mars and this has led to muchspeculation over its features, namely the Martian canals.

The Martian Canals
Early perceptions:
In 1877, an Italian astronomer named Giovanni Schiaparelli discovered
what he thought was a system of ravines and gullies on mars and named
them Canali. This ignited the imagination of fellow scientists and led to wild
speculation on their use and possible origins.

Early perceptions:
By 1894 astronomers had acquired telescopes with better resolution and
higher power. Here is a map drawn by Eugene Antonadi, redrawn by Lowell
Hess, compared to a modern image taken by the Hubble Space telescope that
shows how the images they saw were interpreted by then modern science.

Early Perceptions:
In 1894, Percival Lowell constructed a telescope in Flagstaff, AZ. Based upon
his observations he wrote a series of books from 1895 to 1908 about the
non natural features of the planets surface. His theory was that an
advanced but dying culture had built the canals to draw water from the polar
ice caps to save their dry, dying civilization.

Modern perception:
In 1965, with the arrival of the Mariner spacecraft to Mars, this provided
definitive proof that the canals were indeed based on myth. This notion was
explained as streaks of dust carried by winds down from craters and
mountains or a trick effect of lighting. This was further reinforced by satellite
imagery that confirmed Mars was a dead planet and could not contain water.

Todays Reality:
Thanks to modern science, as recently as 2004 the Mars
Exploration rovers have discovered the presence of liquid water on
Mars. As the planet goes through its seasons much like Earth
does, it heats up and causes mysterious streaks to appear whichthen disappear when it gets cold. Scientists now supposition that it
is evidence of melted, salty water running down slopes during the
Martian summer.

Conclusion:
Recent scientific advancements such asNASAs Mars Reconnaissance Orbiter
have now revealed the possibility offlowing water during the summer
months on Mars. This could tie in to theapparent canal system on Mars. Thereare still many questions to be answeredabout the Martian Canals. Are thereforms of life hitherto unknown on theplanet? Is there enough water on theplanet to sustain life? Only through the
advancement of science will thesequestions, and many others beanswered.
