EARTH'S SPACE ORBIT - APR 22, 2012 (Ungraded): Western United States to Southern Atlantic Ocean. Time lapse from unaltered photos taken by astronauts. HighRes NASA JPEGs muxed into PhotoJPEG video without re-encoding and post-processing. This clip retains 100% of original image quality including camera artifacts. ISS flying in Earth's orbit from northern Nevada to just east of southern Argentina. This video is taken through the Cupola window as the ISS travels southeast over the United States and down to the Gulf of Mexico. The bright city lights of Denver, Dallas, San Antonio, and Houston stand out as the Earth spins by rapidly. As the ISS travels over the dark Gulf of Mexico, the lights of the Yucatan Peninsula stand out before continuing southeast over southern Central America and northern South America. Most of South America is under heavy cloud and flashes of lightning can be seen before the pass ends over the Atlantic Ocean, east of Argentina. (av21893u)
