NASA is a #brand→

Wired:

“Social media strategy for us as a whole has been focused since 2009,” says John Yembrick, the agency’s social media manager. “We have over 500 social media accounts across the agency.” You’ve probably followed them, from astronauts and rovers to entire laboratories. NASA’s follower count across all platforms reaches well into the millions. The agency has actually won awards for its social media. NASA is a #brand.

It’s subtle, but especially with the recent Flickr post of all the Apollo photos, NASA does a great job of keeping their popularity up.
