Файл:Maiao Atoll, Polynesia - Iss065e156801 (cropped).jpg

Maiao is entirely surrounded by a coral reef, which encloses a bright blue tidal lagoon along the southern shoreline. The two greener interior lakes, Roto Iti and Roto Rahi, are almost entirely cut off from the sea. They have become hypersaline—saltier than seawater—as a result of evaporation. Salt-loving organisms thrive in such lakes and contain pigments that change the color of the water.

Much of the atoll is cultivated for coconut oil. Unlike many islands in Polynesia, the people of Maiao decided not to embrace tourism as a major component of their economy. There is no landing strip, and the island can only be reached by a long ferry ride from Tahiti. The landing wharf appears near the northern tip of the atoll, while a road circles most of the island.

Astronaut photograph ISS065-E-156801 was acquired on July 3, 2021, with a Nikon D5 digital camera using a focal length of 1150 millimeters. It is provided by the ISS Crew Earth Observations Facility and the Earth Science and Remote Sensing Unit, Johnson Space Center. The image was taken by a member of the Expedition 65 crew. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports the laboratory as part of the ISS National Lab 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.
