Japan Aerospace Exploration Agency (JAXA) astronaut Soichi Noguchi, Expedition 23 flight engineer, photographed the tail end of the Mississippi Delta showing the oil slick in the Gulf of Mexico on May 4, 2010. Part of the river delta and nearby Louisiana coast appear dark in the sunglint. This phenomenon is caused by sunlight reflecting off the water surface, in a mirror-like manner, directly back towards the astronaut observer onboard the International Space Station (ISS). The sunglint improves the identification of the oil spill which is creating a different water texture (and therefore a contrast) between the smooth and rougher water of the reflective ocean surface. Other features which cause a change in surface roughness that can be seen in sunglint are wind gusts, naturally occurring oils that will be gathered by and take the form of water currents or wave patterns, and less windy areas behind islands.
A crewmember on the joint STS-135/Expediton 28 aggregation photographed this image of parts of Mexico, including Baja California the Gulf of Cortez. Ten astronauts and cosmonauts are currently aboard the joint Atlantis/station complex sharing chores. This photo opportunity presented itself on July 12 — a very busy spacewalk day.
Alcatraz Island and Treasure Island can be seen near the center of this image of the San Francisco Bay, photographed with an 800mm lens some 215 to 220 miles above Earth. The image was taken by an Expedition 22 crew member aboard the International Space Station (ISS). San Francisco bay area structures including office buildings can be at the city’s edge (left).
