When the Apollo astronauts   landed on the Moon in 1969, millions of people were rather sad. The person to blame for this was an artist named Chesley Bonestell.

Yet Bonestell's paintings looked so real that some people thought they were photographs. Even though Bonestell was interested in astronomy, he did not start out as a space artist. As a young man he studied architecture -- the art and science of designing and making buildings. In 1938 Bonestell became a special effects artist in Hollywood. It was here that he learned he could improve his paintings by following the methods used in the movies. In 1944, a popular magazine published a series of Bonestell's paintings of the planet Saturn. He drew Saturn as if it were seen by someone standing on each of the planet's moons. The results were _ . Within a few years, Bonestell's artwork was appearing regularly in magazines and books on astronomy and space flight. Many of Bonestell's artworks had been right all along.

"My mountains were sharp  , and they aren't on the Moon." But he shouldn't have felt bad. No space artist had ever before taken so many people to so many faraway worlds. In the years just before the first manned space flights, Bonestell's artwork prepared people for the amazing space adventure to come. Bonestell's success lay in the fact that   _  .
