After a suspense-packed, seven-hour descent, the European Space Agency’s Philae lander made an unprecedented touchdown on the surface of a comet Wednesday — marking the high point of a $1.3 billion, 10-year mission.
Cheers erupted as the confirming signals were received at the European Space Operations Center in Darmstadt, Germany, at 11:03 a.m. ET. The signals took 28 minutes to travel at the speed of light over the 317 million miles (510 million kilometers) between Comet 67P/Churyumov-Gerasimenko and Earth.
“It is sitting on the surface,” reported Stefan Ulamec, Philae lander manager at the DLR German Aerospace Center. “Philae is talking to us — we are on the comet!”

A comet-chasing space probe that has been in hibernation for almost three years has woken up and sent its first signal back to Earth.
.
The European Space Agency received the all-clear message “Hello World!” from its Rosetta spacecraft some 800 million kilometers (500 million miles) away shortly after 7 p.m. (1800 GMT; 1 p.m. EST).
Rosetta was put into hibernation in 2011 to conserve energy for its long journey to meet with comet 67P/Churyumov-Gerasimenko.
If all goes as planned the probe will rendezvous with the comet in the coming months and drop a lander onto its icy surface in November.
Rosetta is named after a block of stone that allowed archeologists to decipher ancient Egyptian hieroglyphs. Scientists hope the probe’s findings will help them understand the composition of comets and thereby discover more about the origins and evolution of our solar system.
