Isla Blanquilla, Venezuela

The small island of Blanquilla is named for its white sand beaches, visible in this astronaut photograph as a bright border along the northeastern–eastern shoreline. Surface currents extending from the western coastline of the island are caused by easterly trade winds. This dominant wind has also caused movement of beach sand to form white “fingers” extending inland along the east coast.


The featured astronaut photograph ISS015-E-7771 was acquired May 12, 2007, by the Expedition 15 crew with a Kodak 760C digital camera using a 400 mm lens. The image is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Laboratory, Johnson Space Center. The image in this article has been cropped and enhanced to improve contrast. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth.
