Rosetta sets sights on destination comet

Fri, 03/28/2014 - 04:00
The European Space Agency's (ESA) Rosetta spacecraft has caught its first glimpse of its destination comet after waking up from deep-space hibernation on January 20. Rosetta took the "first light" images March 20 and 21 using the Optical, Spectroscopic, and Infrared Remote Imaging System (OSIRIS). These pictures are part of six weeks of activities dedicated to preparing the spacecraft’s science instruments for close-up study of comet 67P/Churyumov-Gerasimenko. OSIRIS, developed under the l
