To the Moon, Alice! (Use Your Internet Connection, Dear)

"Imagine soaring over the surface of the Moon, dipping into a crater and seeing rock slides on its slopes and boulders piled up at the bottom.

Closeups of the crater Tycho

You don't have to wait for a spaceship or even the night sky to get such a close-up view of the Moon. You can visit it now with a PC and a broadband Internet connection, courtesy of a free public-access program developed by the National Aeronautics and Space Administration's Ames Research Center in California.

Users must have a high-speed, broadband Internet connection and a computer running Windows 2000 or XP. World Wind can be downloaded at worldwind.arc.nasa.gov.

Users of the public program have produced a Web site that provides instructions and help, as well as applications that use the World Wind data, such as an add-on program that makes it easier to find spots like the Apollo landing sites, Mr. Hogan said.

These features and help are online at worldwindcentral.com."
