Doug Ellison shared this lovely panorama via Twitter over the weekend. It's from the Mars Exploration Rover Spirit, taken back in 2004.

Visiting Viking at Seattle's Museum of Flight

Tom Dahl • November 14, 2012

One of the nicest aerospace museums in the United States is the Museum of Flight, outside Seattle, Washington.
