Shanghai at Night (NASA, International Space Station, 03/27/12)

Editor's note: happy Friday, Flickr friends! This image is gorgeous, and I encourage you to view in large size. Posted to the NASA Views Earth at Night photoset: www.flickr.com/photos/28634332@N05/sets/72157625188331491/
A nighttime view of Shanghai is featured in this image photographed by an Expedition 30 crew member on the International Space Station. The city of Shanghai sits along the delta banks of the Yangtze River along the eastern coast of China. The city proper is the world's most populous city (the 2010 census counts 23 million people, including "unregistered" residents). With that many humans, the city is a tremendous sight at night. Shanghai is a key financial capital for China and the Asian Pacific region. The bright lights of the city center and the distinctive new skyscrapers that form the skyline along the Pudong district (the eastern shore of the Huangpu River, a tributary of the Yangtze that cuts through the center of Shanghai) make for spectacular night viewing both on the ground and from space. The official census count in 2000 was 16.4 million; the city population has increased more than 35 per cent since that time. Much of the growth has occurred in new satellite developments like areas to the west of the city (for example, Suzhou). The city's rapid growth and development during the 20th and 21st centuries have come at a cost. Water availability is a key concern, and groundwater withdrawal has resulted in substantial subsidence in and around the city. Because it is built only a few meters above sea level -- on the banks of the deltaic estuary of the Yangtze River -- curbing subsidence rates is a critical concern.

Las Vegas, Nevada at Night (NASA, International Space Station, 11/30/10)
Image by NASA's Marshall Space Flight Center
Editor's Note: This is part of a larger Flickr set, "NASA Views Earth at Night," located here: www.flickr.com/photos/28634332@N05/sets/72157625188331491/
This night time image, photographed by an Expedition 26 crew member on the International Space Station, features the Las Vegas, Nevada metropolitan area, located near the southern tip of the state within the Mohave Desert of the southwestern USA. While the city of Las Vegas proper is famous for its casinos and resort hotels -- the city bills itself as "the entertainment capital of the world" -- the metropolitan area includes several other incorporated cities and unincorporated (not part of a state-recognized municipality) areas. Crew members onboard the ISS observe and photograph numerous metropolitan sites when the areas are illuminated by sunlight, but the extent and pattern of these areas are perhaps best revealed by the city lights at night. The surrounding dark desert presents a stark contrast to the brightly lit, regular street grid of the developed metropolitan area. The Vegas Strip (center) is reputed to be the brightest spot on Earth due to the concentration of lights associated with its hotels and casinos. The tarmac of McCarran International Airport to the south is a dark feature by comparison. The airstrips of Nellis Air Force Base on the northeastern fringe of the metropolitan area are likewise dark compared to the well-lit adjacent streets and neighborhoods. The dark mass of Frenchman Mountain borders the metropolitan area to the east. Acquisition of focused night time images such as this one requires space station crew members to track the target with the handheld camera while the ISS is moving at a speed of more than seven kilometers per second (15,659 miles per hour) relative to Earth's surface. This was achieved during ISS Expedition Six using a homemade tracking device, but subsequent crews have needed to develop manual tracking skills. These skills, together with advances in digital camera technology, have enabled recent ISS crews to acquire striking night time images of Earth.
