WASHINGTON โ€”


A Boeing Delta 2 rocket successfully launched WorldView-1, the first of a new generation of U.S. government-financed but privately owned imaging satellites, Sept. 18 from Vandenberg Air Force Base, Calif.



Capable of distinguishing ground objects or features as small as 50 centimeters across, WorldView-1, owned by DigitalGlobe of Longmont, Colo.,




is the highest-resolution commercial imaging satellite launched to date.

WorldView-1 now will undergo testing and is expected to begin sending imagery back to Earth in about a month, DigitalGlobe spokesman Chuck Herring said. Built by Ball Aerospace and Technologies Corp. of Boulder, Colo., the satellite is designed to operate for seven years, he said.

WorldView-1 is one of two satellites whose development was financed in part by the U.S. National Geospatial-Intelligence Agency (NGA), which is responsible for analyzing and distributing geospatial data for the U.S. military and intelligence community. Under a program known as NextView, the NGA awarded imagery-service contracts to DigitalGlobe and rival GeoEye of Dulles, Va., worth about $500 million apiece. The deals included upfront funding for the new satellites, whose imagery also will be available for commercial sale, albeit with some restrictions.

NextView
is the follow-on to the NGAโ€™sClearView contracting vehicle, under which the agency buys imagery from the companiesโ€™ existing, less-capable imaging satellites. DigitalGlobeโ€™sQuickBird and GeoEyeโ€™sIkonos satellites were built and launched exclusively with private funding.

QuickBird
, built by Ball and launched in 2001, collects black-and-white imagery with 61-centimeter resolution and multispectral, or color, imagery with 2.5-meter resolution. The satellite is expected to last until the end of 2009, when it will run out of fuel and burn up as it re-enters the atmosphere.



WorldView-1 will be the highest-resolution commercial satellite in orbit until GeoEyeโ€™s GeoEye-1




, built with NextView funding, is launched in early 2008. GeoEye-1 will be capable of collecting black-and-white imagery with 41-centimeter resolution as well as multispectral imagery.

โ€œWe are excited about and eagerly await delivery of the first new imagery,โ€ U.S. Navy Vice Adm. Robert Murrett, the NGAโ€™s director, said in a statement released Sept. 18. โ€œWith the improved resolution, agility and capacity of the WorldView-1 satellite, we anticipate increasing the use of commercial imagery to satisfy our geospatial production requirements.โ€

DigitalGlobe
is planning to launch another imaging satellite exclusively with private funding. WorldView-2 will be similar in resolution to WorldView-1 but also will be able to collect multispectral imagery in eight bands. WorldView-2 also is being built by Ball, with completion expected by the end of 2008.
