Photo Shows Lander Sitting On Comet 

"The European Space Agency released a new photo Thursday of the Philae lander safely resting in its new home on the surface of Comet 67P/Churyumov-Gerasimenko, as it hurtles through space. The agency's data also show the lander bounced twice before coming to rest."

"Wednesday's historic landing came after hours of tension, as the ESA awaited signs from Philae and its parent craft, the orbiter Rosetta, that the robotic lander had arrived on the comet's surface and was able to function."

"Even as the ESA's scientists and engineers celebrated their achievement, they also began trying to puzzle out new technical challenges."
