This image of Houston, Texas, shows the amount of detail that is possible to obtain using spaceborne radar imaging. Images such as this -- obtained by the Spaceborne Imaging Radar-C/X-band Synthetic Aperture Radar (SIR-C/X-SAR) flying aboard the space shuttle Endeavor last fall -- can become an effective tool for urban planners who map and monitor land use patterns in urban, agricultural and wetland areas. Central Houston appears pink and white in the upper portion of the image, outlined and crisscrossed by freeways. The image was obtained on October 10, 1994, during the space shuttle's 167th orbit. The area shown is 100 kilometers by 60 kilometers (62 miles by 38 miles) and is centered at 29.38 degrees north latitude, 95.1 degrees west longitude. North is toward the upper left. The pink areas designate urban development while the green-and blue-patterned areas are agricultural fields. Black areas are bodies of water, including Galveston Bay along the right edge and the Gulf of Mexico at the bottom of the image. Interstate 45 runs from top to bottom through the image. The narrow island at the bottom of the image is Galveston Island, with the city of Galveston at its northeast (right) end. The dark cross in the upper center of the image is Hobby Airport. Ellington Air Force Base is visible below Hobby on the other side of Interstate 45. Clear Lake is the dark body of water in the middle right of the image. The green square just north of Clear Lake is Johnson Space Center, home of Mission Control and the astronaut training facilities. The black rectangle with a white center that appears to the left of the city center is the Houston Astrodome. The colors in this image were obtained using the follow radar channels: red represents the L-band (horizontally transmitted, vertically received); green represents the C-band (horizontally transmitted, vertically received); blue represents the C-band (horizontally transmitted and received). http://photojournal.jpl.nasa.gov/catalog/PIA01783

ISS024-E-010403 (31 July 2010) --- This detailed image ? photographed by an Expedition 24 crew member on the International Space Station (ISS) ? is centered on the NASA Lyndon B. Johnson Space Center (JSC), located in the southeastern Houston, TX metropolitan area. While initially being represented by a number of temporary locations in Houston, the facility was established in 1961 as the Manned Spacecraft Center and renamed in honor of the late U.S. President Johnson (a Texas native) in 1973. JSC serves as the lead NASA center for both astronaut training and mission control of manned spacecraft - such as the ISS and space shuttle - and has done so throughout the history of the U.S. manned space program. The Center also collaborates with other NASA and international partner facilities in a variety of scientific and engineering programs related to human spaceflight and planetary exploration. JSC is located approximately midway between downtown Houston and Galveston, TX, and is bordered by several smaller municipalities that form a mosaic of urban and suburban land use (grey areas with street grids, and commercial/industrial areas characterized by white rooftops). Large tracts of grassy fields and forests in the area (light to dark green respectively) include nature preserves, grazing lands, and flood control areas. Also visible at upper left is Ellington Field. This airport services a variety of NASA aircraft used for astronaut training, scientific, and cargo transport purposes. Clear Lake, an inlet of Galveston Bay, is located to the immediate southeast of JSC. Both Clear Lake and Galveston Bay appear silver-grey due to sunglint, or light reflected back towards the observer on the ISS that gives the water surface a mirror-like appearance. Several boat wakes are visible in Galveston Bay (right) due to disruption of the water surface that reduces the sunglint effect.
