Comet Landing!

Comet 67P/Churyumov–Gerasimenko
So 10 years ago, mankind launched a box named Rosetta into space. It traveled over 4 billion miles to sync up with the orbit of comet 67P, a hunk of rock and ice only 2.5 miles in diameter and travelling 85K MPH. The comet is believed to have formed 4.6 billion years ago with material leftover from when the solar system was coalescing. Rosetta launched a lander Philae to the surface of the comet yesterday and, after bouncing twice (harpoon failure!), the comet is safely on the surface in a gravity just .01% of the Earth.

I'm awestruck, in the true sense of the word. And best of all, the comet is singing!
