Spacecraft Messenger is doing a drive by today on Mercury –

Right around noon today, if all goes as planned, a spacecraft called Messenger will swoop past the planet Mercury and begin two days of unprecedented picture-taking and data-collecting.

The flyby, the first visit to Mercury in more than 33 years by an emissary from Earth, will mark a key moment in a NASA mission that will ultimately place the first satellite into orbit around the tiny planet that sits closest to the sun.
