A VIEW FROM NASA'S SHUTTLE ANTELOPE VALLEY MAPPED BY RADAR.


Byline: Daily News

PALMDALE - The National Aeronautics and Space Administration released a computer-animated 3-D flyover of the Antelope Valley, created with detailed mapping data from NASA's recent shuttle radar topography mission.

The video, released on NASA's satellite television channel, zooms along a 90-mile stretch of the San Andreas Fault San Andreas fault, great fracture (see fault) of the earth's crust in California. It is the principal fault of an intricate network of faults extending more than 600 mi (965 km) from NW California to the Gulf of California. The San Andreas fault, a strike-slip fault, also extends vertically at least 20 mi (30 km) into the earth. to the intersection with the Garlock Fault near Gorman - which NASA called one of the region's greatest quake hazards.

Stills from the video are available at www.jpl.nasa.gov/pictures/srtm.

The February flight of the space shuttle carried a Jet Propulsion Laboratory experiment that used a 200-foot antenna boom - the largest structure ever extended from the shuttle - to gather mapping data over almost 80 percent of Earth's surface.

In what has been called ``the most successful science shuttle mission ever,'' the huge amount of data returned from the shuttle radar topography mission represents a giant leap forward in knowledge of Earth's surface, JPL JPL - Jack Parsons Lives

The 3-D images of Earth's surface will be used for a wide variety of ecological, geological, meteorological, sociological and civil engineering projects, they said.

Similar imagery of the entire Earth will be available in coming months, JPL officials said.
