For nearly a century before there was such a thing as a space program,a view of space was possible.People could see detailed views of the Moon,explore Mars,and study the geometric beauty of Saturn's rings.All of this was made possible by a small group of artist astronomers who made a career of illustrating how other worlds in space might look.

　　Lucien Rudaux,a French artist,was the first to combine his artistic talents with his knowledge of astronomy.His paintings show a mixture of skilled observations,brilliant imagination,and painstaking(煞費(fèi)苦心的)attention to detail.As a result,many of his works have come surprisingly close to actual conditions on distant planets.His paintings of Mars included moonlike craters (碗形洞)that were first photographed by the Mariner 4 probe(探測(cè)衛(wèi)生)in 1965.His 1930 painting of a dust storm looks remarkably like a photograph of a storm taken by Orbiter 2 in 1976.

　　The srtist astronomers,in cluding Rudaux,stimulated interest in outer space by painting what enevtually turned out to be precise portraits(準(zhǔn)確的模型)of the planets.
