Google's Super Satellite Captures First Image

This bird's-eye view of Kutztown University in Pennsylvania was the first image ever seen by the GeoEye-1, the world's highest-resolution commercial satellite sponsored by Google, when it opened its camera door earlier this week.

The 4,300-pound satellite collected the image at noon EDT on Oct. 7 while moving from the north pole to the south pole in a 423-mile-high orbit at 17,000 miles per hour, or 4.5 miles per second. The spacecraft can take photos at a resolution of up to 41 cm -- close enough to zoom in on the home plate of a baseball diamond, according to Mark Brender, GeoEye's vice president of communications and marketing.

Even though the GeoEye-1 satellite sports a colorful Google sticker, its key customer is actually not Google but rather the National Geospatial-Intelligence Agency, a U.S. government agency that analyzes imagery in support of national security. The NGA is paying for half of the development of the $502 million satellite and has committed to purchasing imagery from it. Google is GeoEye's second major partner.

"This is the opposite of a spy satellite," Brender said in a phone interview. "Spies don't put info on the internet and sell imagery. We're an Earth-imaging satellite, and we can sell our imagery to customers around the world who have a need to map and measure and monitor things on the ground."
