Everything about Philae lander blows my mind: that it landed on a comet! That the moon is 1 light second from us & Comet 67P/Churyumov-Gerasimenko is 28 light minutes away. That it took 10 years to get to a comet more than 300 million miles from Earth. That scientists managed to figure out how to build something that could land on a tiny chunk of ice that far from here. How it sounds (click on the photo caption). That we can see a comet up close! Rosetta, Philae lander's mother ship, is the first spacecraft to orbit a comet’s nucleus or fly next to a comet headed toward the inner solar system—it will be able to tell from up close how a comet is transformed as it approaches the sun. It kills me how cool this is.
