February 2, 2008: Happy face on Mars

[Undertoad]

It isn't the first face symbol they've found on Mars, but it's the happiest. The Planetary Society blog offers this one courtesy of NASA / JPL / MSSS:

This picture of a crater resembling a "happy face" was acquired by the Context Camera (CTX) on Mars Reconnaissance Orbiter on January 28, 2008. The unnamed crater is about 3 kilometers (1.9 miles) across. It is located among the Nereidum Montes, north of the Argyre basin, near 45.1 S, 55.0 W. North is toward the right and sunlight illuminates the scene from the upper right.
