But if you're a little camera shy, don't worry - you'll have a chance to perfect your long-distance grin when MESSENGER starts shooting at 7:49, 8:38, and 9:41 a.m. EDT on the same day.
(Have prior engagements? It's OK - MESSENGER will also be capturing images on Saturday at the same times.)
Of course, MESSENGER isn't out there just to see what Earth looks like from .65 AU. It's on the hunt for natural satellites around Mercury, any possible moons present around the innermost planet that, for some reason, have not yet been detected.

"We don't know why Mercury does not have a moon," said William Merline, of the Southwest Research Institute (SwRI) in Boulder, Colorado. "It may have been just unfortunate in not having the right history, in terms of collisions," Merline continued. "Or it may at one time have had a moon in an orbital trajectory that was disrupted by the strong gravitational pull of the Sun... but these possibilities are only speculations, based on theoretical ideas. To complete the picture, we must search for the existence of satellites to validate any of these suggestions."
