APOD: All of Mercury (2013 Jun 12) Image Credit: NASA / JHU-APL / CIW http://apod.nasa.gov/apod/ap130612.html http://www.youtube.com/watch?v=DmYK479EpQc Explanation: For the first time, the entire surface of planet Mercury has been mapped. Detailed observations of the innermost planet's surprising crust have been ongoing since the robotic MESSENGER spacecraft first passed Mercury in 2008 and began orbiting in 2011. Previously, much of the Mercury's surface was unknown as it is too far for Earth-bound telescopes to see clearly, while the Mariner 10 flybys in the 1970s observed only about half. The above video is a compilation of thousands of images of Mercury rendered in exaggerated colors to better contrast different surface features. Visible on the rotating world are rays emanating from a northern impact that stretch across much of the planet, while about half-way through the video the light colored Caloris Basin rotates into view, a northern ancient impact feature that filled with lava. MESSENGER has now successfully completed its primary and first extended missions. http://photojournal.jpl.nasa.gov/catalog/PIA16850 http://photojournal.jpl.nasa.gov/catalog/PIA16852 http://photojournal.jpl.nasa.gov/catalog/PIA16853 APOD: Colors of Mercury (2013 Mar 01) http://apod.nasa.gov/apod/ap130301.html Starship Asterisk* • APOD Discussion Page http://asterisk.apod.com/discuss_apod.php?date=130612 Starship Asterisk* • On This Day in APOD http://asterisk.apod.com/view_retro.php?date=0612
