The mediocre engineer in me can't look at those photos and just appreciate them...all I can think about is...geez, the mechanical acuity to took to make sure all the moving pieces moved...from the shutter to the antenna that receives the signal and transmits the data...at the right time, 300+ million miles away. What a party those engineers must he having right now.

Came across the other NYT news article on this...this is the kind of detail that I imagine must keep those rocket engineers up for many nights during and after launch:

> The operation proceeded despite a few small glitches and one potential showstopper problem: an apparent failure of a thruster that was to fire right after touchdown to press the lander against the comet’s surface. A pin was supposed to break a wax seal on the gas tank, but repeated attempts did not appear to succeed.
