ISS028-E-014782 (6 July 2011) --- The Shoemaker (formerly Teague) Impact Structure, located in Western Australia in a drainage basin south of the Waldburg Range, presents an other-worldly appearance in this detailed photograph recorded from onboard the International Space Station on July 6. The Shoemaker impact site is approximately 30 kilometers in diameter, and is clearly defined by concentric ring structures formed in sedimentary rocks (brown to dark brown, image center) that were deformed by the impact event approximately 1630 million years ago, according to the Earth Impact Database. Several saline and ephemeral lakes—Nabberu, Teague, Shoemaker, and numerous smaller ponds—occupy the land surface between the concentric ring structures. Differences in color result from both water depth and suspended sediments, with some bright salt crusts visible around the edges of smaller ponds (image center The Teague Impact Structure was renamed Shoemaker in honor of the late Dr. Eugene M. Shoemaker, a pioneer in the field of impact crater studies and planetary geology, and founder of the Astrogeology Branch of the United States Geological Survey. The image was recorded with a digital still camera using a 200 mm lens, and is provided by the ISS Crew Earth Observations experiment and Image Science & Analysis Laboratory, Johnson Space Center.
