First results, here published in the NATIONAL GEOGRAPHIC MAGAZINE, reveal no new discoveries but clarify details. Not even the giant eye, however, is able to distinguish the Martian network of lines, some of them 1,500 miles long, which astronomers can see but cannot yet photograph. One observer convinced himself that the lines were canals dug by intelligent beings to carry irrigation waters from icecaps to parched central regions. Blue light, which cannot penetrate atmosphere, was used in taking the view above. White areas at the poles appear to be fog above thin layers of snow. Penetrative red light exposed the scene below. Large dark areas may show vegetation, for they vary in color with the Martian seasons, appearing blue-green in spring, browner in fall.
