BERLIN – The European Space Agency has confirmed the time and place it will attempt to land the first spacecraft on a comet.
The agency said Wednesday its unmanned probe Rosetta will release the 100-kilogram (220-pound) lander at 0835 GMT (3:35 EST) on Nov. 12.
The aim is to drop its lander Philae at a location dubbed 'Site J' on the 4-kilometer (2.5-mile) wide comet 67P/Churyumov-Gerasimenko.
The maneuver will take about seven hours. Because radio signals have to travel more than 400 million kilometers (250 million miles) back to Earth, confirmation of a successful landing won't arrive until about 1600 GMT (11:00 a.m. EST).
Scientists hope the mission will help them learn more about the origins and evolution of objects in the universe.
