Washington ? The United States has more satellites than the rest of the world combined.

The scorecard: U.S. 413, all others 382, according to a new database that catalogs the high-flying technology that does everything from transmit music to snoop on adversaries.

The inventory, released Wednesday by the Union of Concerned Scientists, provides details on some of the Pentagon’s most secret satellites, which may gather images in the dark or take high-resolution pictures from 12,000 miles away.

“Until now, the general public didn’t have easy access to information about all active satellites,” said Dr. Laura Grego, a Cambridge astrophysicist who was on a team that spent several years compiling information on the nearly 800 active satellites. “No one owns space, so everyone has a right to know what’s up there.”

The material was gleaned from corporations, academics, governments and satellite watchers who as a hobby spend their nights watching the skies for flickers of light.

The group’s inventory lists 21 different details on satellites with missions ranging from weather forecasting to transmitting music and news for companies like Sirius Satellite Radio. Perhaps most controversially, the repository includes what’s known about top-secret spy satellites run by the U.S. and other governments. The database can be downloaded on the UCS Web site, www. ucsusa.org.

With 413, the United States far exceeds other nations in numbers of satellites, often used for communications. The Russians have 87. The Chinese have 34.
