Here is a rare two-fer day on blogs!
At dusk February 7, be sure to go out and look for Mars andMercury close together in the western sky. You will need a pair of binoculars and a clear view of the horizon to spot the close pair but it will be worth your effort.

If you see the two smallest planets in the solar system, think about the following. Curiosity and Opportunity rovers are at work on Mars while Mars Reconnaissance Orbiter is high overhead. Mercury has MESSENGER in orbit gaining daily data on the planet closest to the Sun.
