68. At last: Rosetta's Mars flyby photos have been released!

(Web Page; Tue Jul 29 13:29:00 CDT 2014)

On February 24, 2007, the European Space Agency's Rosetta spacecraft passed by Mars, the second of four planetary gravity-assist flybys on its long route to a 2014 rendezvous with comet Churyumov-Gerasimenko. At the time, they released t...

Description: On February 24, 2007, the Rosetta spacecraft passed by Mars, the second of four planetary gravity-assist flybys on its long route to a 2014 rendezvous with comet Churyumov-Gerasimenko. At the time, they released two photos from the main science camera, OSIRIS.

69. The Very Large Telescope sights Rosetta's comet target, sees activity beginning

(Web Page; Mon Mar 10 14:18:00 CDT 2014)

The European Southern Observatory has just released the first photo of Rosetta's cometary target, 67/P Churyumov-Gerasimenko, since the comet's passage behind the Sun as seen from Earth. It's not a very impressive photo; it is more impor...
