Once there, the Rosetta probe will take pictures, make measurements and drop a probe down to the comet's surface. Last January, NPR science correspondent Joe Palca reported that for more than two years the spacecraft had shut off most of its instruments, including the radio for communicating with Earth, in order to save energy.

Plots unfold. And this summer, NPR science correspondent Joe Palca has been telling us how science unfolds. It's series we're creatively calling Unfolding Science.<p>(SOUNDBITE OF THEME SONG)<p>BLOCK: Today, Joe tells us about large biological molecules called proteins that have to fold and unfold properly to keep us alive.<p>JOE PALCA, BYLINE: When we talk about food, protein is a kind of nutrient you get in meat, fish or foul.

I'M Tess Vigeland. Let us contemplate the American teenage girl, perhaps the very first one. Apparently, there's been some scientific debate about who she is and whether she hails from the same gene sequence as what we think of as the first Americans, American Indians. And when I say gene sequence, we're not talking about Skinnies from Urban Outfitters. Sun, 18 May 2014 21:00:00 +0000 Joe Palca 18664 at http://aspenpublicradio.org
