Special Collection: MESSENGER Orbits Mercury

Def

Launched in 2004, the MESSENGER (MErcury Surface, Space ENvironment, GEochemistry, and Ranging) spacecraft completed one flyby of Earth, two flybys of Venus, and three flybys of Mercury before entering Mercury's orbit on 18 March 2011. In the 30 September 2011 Science, seven Reports present high-resolution images and x-ray data that provide new details about the surface composition of Mercury, as well as the planet's geologic history, and magnetic field.


"Tour" Mercury on Google Earth

The MESSENGER Education and Public Outreach team, of which Science's publisher, the American Association for the Advancement of Science, is one of four member organizations, has worked with some of the authors of the papers publishing this week to develop audio tours of Mercury on Google Earth. To check out the tours, go to the Google Tours page at the Messenger Education and Public Outreach Web site. (Requires download of Google Earth software.)
