featuring the water canels on MArs of 1906 thus it means that water exist on Mars indicates that Early news of Mars as having been a civilazation could perhaps be correct?

1909: W. W. Campbell of Lick Observatory, tries to measure water vapor in the Martian atmosphere using spectroscopy from an expedition to Mount Witney. Results are negative and he (correctly) concludes that the Martian atmosphere is extremely arid compared to the Earth.

1909 Camille Flammarion publishes the second volume of his encyclopaedia of Mars La Planète Mars et ses Conditions d'Habitabilité (Gauthier-Villars et Fils, Paris). Vol 2 (595 pages) contains 426 drawings and 16 maps from the period 1860 to 1901.

An unfortunate dog, minding its own business in Nakhla, Egypt, is struck by part of a meteorite and killed. Later, in the 1980s, this meteorite is identified as one of a small group originating from Mars. There are currently 16 meteorites from Mars . These were formerly classed as "SNC meteorites", refering to the places where typical meteorites of their kind where found (Shergotty-Nakhla-Chassigny); however, now the term "Martian meteorites" is preferred because some recent meteorites, most notably the oldest one, ALH84001, cannot be accurately classified as SNC. What's certain, however, is that that dog was really unlucky.

1911: "Frost on Mars"--Lowell (New York Times, Nov 10)
Planum Boreum, Mar’s north polar cap contains water ice “of a very high degree of purity,” according to an international study. Using radar data from the SHARAD (SHAllow RADar) instrument on board the Mars Reconnaissance Orbiter (MRO), French researchers say the data point to 95 percent purity in the polar ice cap. The north polar cap is a dome of layered, icy materials, similar to the large ice caps in Greenland and Antarctica, consisting of layered deposits, with mostly ice and a small amount of dust. Combined, the north and south polar ice caps are believed to hold the equivalent of two to three million cubic kilometers (0.47-0.72 million cu. miles) of ice, making it roughly 100 times more than the total volume of North America’s Great Lakes, which is 22,684 cu. kms (5,439 miles).

The study was done by researchers at France’s National Institute of Sciences of the Universe (Insu), using the Italian built SHARAD radar sounder on the US built MRO. SHARAD looks for liquid or frozen water in the first few hundreds of feet (up to 1 kilometer) of Mars’ crust by using subsurface sounding. It can detect liquid water and profile ice.

Mars southern polar cap was once thought to be carbon dioxide ice, but ESA’s Mars Express confirmed that it is composed of a mixture of water and carbon dioxide.

The study on Mars north polar cap appears in the journal Geophysical Research Letters, published by the American Geophysical Union
