@NASA congratulates the European Space Agency for Philae probe's successful landing on a comet! It's a significant event because comets are building blocks of the universe. Closely studying a comet, like how we've been studying the moon and sun, can unravel mysteries of our universe! Why has it taken this long? Comets travel a lot faster than a space ship leaving Earth, making it a challenge for the craft to pick up acceleration. Scientists say it's like a fly trying to land on a bullet. ? See what the world has been posting with #cometlanding.
