A scientist of European space agency ESA stands at an airworthy copy of space probe 'Rosetta' in the ESA control center in Darmstadt, Germany, Monday, Jan. 20, 2014. Scientists at the European Space Agency are expecting their comet-chasing probe Rosetta to wake from almost three years of hibernation at 11 a.m. Monday Jan. 20, 2014 (1000 GMT; 5 a.m. EST) and phone home to say all is well. The scientists are facing an agonizing wait of several hours until the first signal reaches Earth. (AP Photo/dpa, Daniel Reinhardt)
