The Grand Canyon twists through Arizona for 277 miles, creating a spindly signature that satellites can see from hundreds of miles up. But not every view of the natural wonder is as clear as Landsat 8's imagery from October and November. Last week, the canyon was shrouded with thick fog — and satellites were on hand to see that as well.
NASA's Earth Observatory website highlights pictures from those foggy days, including aerial views from the Terra and Aqua satellites as well as a time-lapse video from the GOES-West satellite. These images documenting the ebb and flow of the Grand Canyon's fog are the latest offerings from our Cosmic Log Space Advent Calendar, which is providing a daily dose of satellite imagery through Christmas. For more holiday goodies, check out The Atlantic's Hubble Advent Calendar, Zooniverse's Advent calendar and the Galileo's Pendulum Science Advent Calendar.
