T-Minus 24 Hrs to Mercury

Hey Space Placers!

NASA and Johns Hopkins' MESSENGER (MErcury Surface, Space ENvironment, Geochemistry, and Ranging) spacecraft is on autopilot for orbital insertion around Mercury on March 17th at 8:45 p.m. EDT.

You can tune in to a live webcast on the 17th at 7:55 p.m. See for the link.

The weather around the Washington D.C. area should be great for viewing Mercury live just before orbital insertion. See my previous blog on spotting the planet closest to the Sun. My pic below shows you what Jupiter and Mercury look like - Mercury is dimmer and to the right of Jupiter. Since this picture was taken Mercury is higher up and to the right of Jupiter.
