Alexandria, Va. — "Hello World." Upon hearing that brief message, scientists at the European Space Agency (ESA) and followers around the world sent up a collective cheer. Rosetta — the ESA spacecraft currently on a 10-year mission to orbit and land on a comet — awoke in January after a three-year hibernation, and was ready to get to work.
The Rosetta spacecraft launched on March 2, 2004, to study Comet 67P/Churyumov-Gerasimenko. In August, Rosetta will enter the comet's orbit. By November, scientists will plant a lander on the comet, in the hope of learning more about the conditions at the dawn of our solar system.
