English: This detailed astronaut photograph is centred on the NASA Lyndon B. Johnson Space Center (JSC), located in the south-eastern
Houston metropolitan area.
JSC is located approximately midway between down-town Houston and Galveston, 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 image 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 south-east of JSC. Both Clear Lake and Galveston Bay appear
silver-grey due to sun-glint, 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 (image right) due to disruption of the water surface that reduces the sun-glint effect.
