External High Definition Camera (EHDC) photograph ISS064-E-11821 was acquired on December 11, 2020, with a Nikon D4 digital camera using a 100 millimeter focal length and 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 an externally-mounted camera on the ISS during Expedition 64. The image has been cropped and enhanced to improve contrast, and lens artifacts have been removed. The International Space Station Program supports use of the EHDC for Earth observation, acquiring images of Earth that will be of value to scientists and the public, and making 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. Caption by Alex Stoken, Jacobs, JETS Contract at NASA-JSC.
