ROSETTA COMET: The European Space Agency's Rosetta probe has reached
67P/Churyumov-Gerasimenko and is maneuvering to go into orbit around the
comet's core. This is an historic event. After Rosetta goes into orbit,
it will follow the comet around the sun, observing its activity from
point-blank range. Moreover, in November, Rosetta will drop a lander
onto the comet's strange surface.
