National Geographic : 1970 Aug
Portraitist for the family of planets, artist Ludek Pesek touches up his paintings at National Geographic headquarters in Wash ington, D. C. He worked more than a year preparing the illustrations for this article. A native Czech who now lives in Swit zerland, the versatile Mr. Pesek not only has illustrated two widely published books on the planets, but also has written five novels. Summer nibbles at the south polar cap of Mars (upper painting), evaporating dry ice from sunlit slopes. Drifted fields of carbon dioxide snow spread beneath a CO 2 haze. View from Phobos, one of two Martian moons, shows a jewel-like sunrise glinting above the inky planet. The haze layer close by the sun, just above the rim, was first observed by Mariners 6 and 7. The latter, photographing Phobos from only 82,000 miles, revealed that this moon is shaped like a baking potato, 11 by 14 miles in size.
