ISS031-E-035310 (15 May 2012) --- Sunglint and clouds off Western South America are featured in this image photographed by an Expedition 31 crew member on the International Space Station. The setting sun highlights cloud patterns above the Pacific Ocean, as well as the ocean surface itself in this impressive image. The space station was located over the Andes Mountains of central Chile at the time. The view is looking towards the Pacific Ocean and the sun setting in the west (towards lower left). Light from the setting sun reflects off the water surface towards the observer on the space station and creates a mirror-like appearance—a phenomenon known as sunglint. Bands of relatively low altitude cumulus clouds appear much like a flotilla of ships with their west-facing sides illuminated by the waning sunlight and the rest in shadow (center). Due to the low sun angle, they cast long and deep shadows over large swaths of the ocean surface. Given the short camera lens used, an individual cloud shadow may extend for miles. Light gray clouds at upper right appear to be at a higher altitude. The cloud cover is likely a remnant of a frontal system that moved inland over South America from the Pacific a day or two prior to the time the image was taken.

ISS031-E-006398 (30 April 2012) --- Lake Powell and the Rincon in Utah are featured in this image photographed by an Expedition 31 crew member on the International Space Station. This photograph highlights part of Lake Powell; the lake extends across southeastern Utah and northeastern Arizona. Lake Powell started filling in 1963 when the Glen Canyon Dam on the Colorado River in Arizona was completed, and Glen Canyon flooded. The serpentine water surface of the reservoir-highlighted by gray regions of sunglint-follows the incised course of the canyon. Today Lake Powell is part of the Glen Canyon National Recreation Area which extends for more than 186 miles along the shoreline and side canyons. The primary intended use of Lake Powell?s water is support of agricultural production, with a small portion allocated to urban use in Arizona, Nevada, and California. The reservoir did not reach its maximum capacity of 27 million acre-feet until 1980. More recently, extended drought conditions in the southwestern United States over the past decade have resulted in a significant lowering of the Lake water level and emergence of parts of Glen Canyon. Should average precipitation in the Colorado River watershed lessen (as predicted by regional climate change models), that could result in further lowering of the Lake Powell water level and changes to the current water management plans. Fluctuations in water levels and change of river courses are a common occurrence seen in the geologic record of rivers. Looking somewhat like a donut or automobile tire from the vantage point of the space station, the Rincon (center) is an entrenched and abandoned meander, or loop, of the Colorado River, thought to have formed several thousand years ago when the river cut straight across the ends of the loop and shortened its course by six miles. The resulting canyon and 600 ? 750 feet-high central mesa indicate where the river used to flow. The term ?Rincon? also is used by geomorphologists to describe similar ancient river features observed elsewhere. The Goosenecks of the San Juan River are an example of an active entrenched meander.

Dragon became the first commercially developed space vehicle to be launched to the station to join Russian, European and Japanese resupply craft that service the complex while restoring a U.S. capability to deliver cargo to the orbital laboratory. Dragon is scheduled to spend about a week docked with the station before returning to Earth on May 31 for retrieval.
