Wasco, California advertises itself as the "Rose Capital of the World," producing 55% of the rose bushes sold in the United States. Located in the central San Joaquin Valley, Wasco attracted rose producers in the 1960s, when southern California fields were sold for housing developments. Today, over 8000 acres are devoted to cultivation of existing and new varieties of roses, shipped to every state in the US and all over the world. The image covers an area of 10.4 x 15.8 km, was acquired July 10, 2011, and is located near 35.6 degrees north latitude, 119.3 degrees west longitude.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of 15 to 90 meters (about 50 to 300 feet), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are: monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory, Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington, D.C.
