Curiosity: A Perfect Moment...

Yesterday Curiosity stretched its articulated arm for the first time since before it was launched toward Mars.  There are five separate joints on the arm, and all of them were “exercised”.  Curiosity's numerous cameras watched every motion to verify that it worked correctly – and it did!

Curiosity's first days remind me a little bit of a butterfly emerging from its chrysalis – various parts are being pulled out, stretched, tried out, checked out, and calibrated.

And they're all working perfectly so far!
