Update: The European Space Agency received a signal from the Philae lander around 11 a.m. EST confirming that Philae has landed on the surface of the comet.
Today, on a frigid space rock half a billion kilometers from Earth, history will be made.
The European Space Agency's Rosetta space probe has deployed its robotic lander Philae, which is now set to touch down on Comet 67P/Churyumov-Gerasimenko.

Philae will land on an area called Agilkia, using harpoons and screws to latch on to the surface.
Plans call for Philae to collect samples and take measurements of the comet to help determine its composition and origin. The comet, which is about four kilometers in diameter, is located halfway between the orbits of Jupiter and Mars.
