Reminder: Humans Can Do Wonders

Rosetta comet
NAVCAM image of the comet 67/P Churyumov-Gerasimenko, taken by the Rosetta spacecraft on Aug. 12, 2014. The nucleus is 4 kilometers across and looks like sculpted whip cream. (It’s actually various kinds of ices and rock.)

Just a reminder: Humans have a spacecraft tailing a 4-billion-year-old comet more than 400 million kilometers away and moving at nearly 16 km/sec, all the while taking pictures, sampling material blown out of the primordial snowball’s guts, and generally just being awesome.

You’re welcome.
