Exotic Sunset
Everyone has a sunset photo they love, and we're no different.
After a mild day of temperatures reaching 20° Celsius (70° F) in this equatorial locale, the sun dipped down behind the ancient lake bed at 6:07pm, a beautiful contrast of horizon and sky. Unfortunately, the temperature would soon reach close to -73° Celsius (-100° F), as this lake bed is the Gusev Crater, a 3 to 4 billion year-old dry basin on the surface of Mars.
This panoramic photo mosaic was captured by Spirit, NASA's Mars Exploration Rover on May 19, 2005, its 489th Martian day.
