This image of the El Paso-Juárez area on the U.S.-Mexico border is the 100,000th photograph of Earth that astronauts have taken from the International Space Station. It was taken on January 26, 2004, by Expedition 8 crewmembers. The Rio Grande can be seen meandering through the area, forming the boundary between the sister cities of El Paso, Texas and Juárez, Chihuahua. North is to the right in this image, and the setting sun has cast the east side of the Sierra Juárez and Franklin Mountains into shadow.
When the Apollo 11 astronauts left the surface of the Moon on July 21, 1969, they brought home samples of solar wind particles, lunar rocks and dirt, and a big helping of perspective.
