This image of wildfire smoke at night was captured by the Expedition 31 crew on the International Space Station. Faint smoke is visible drifting near Ciudad Juaréz, Mexico, and El Paso, Texas — neighboring border cities along the Rio Grande. It isn’t possible to distinguish the U.S./Mexico border, but a line of lights along Interstate 10—which is slightly north of the border—is visible. (See this story: http://earthobservatory.nasa.gov/Features/CitiesAtNight/ - about city lights viewed from space for a clearer view of Interstate 10 and the border). It’s likely the smoke originated from the Whitewater-Baldy wildfire, a large blaze that has been burning 225 miles to the northeast of El Paso in Gila National Forest.
The photo was taken on June 2, 2012, with a Nikon D3S, a digital single-lens reflex camera identical to what’s available to consumers.
