A late-1960s ad that ran in Scientific American, scanned and shared in the Boing Boing Flickr pool by fdecomite.
The look is true to Mad Men, and the copy is true to life: I bet the Mars Curiosity team say stuff like that to each other all the time.
Give that dude a mohawk—oh, and increase NASA's budget so JPL can hire, instead of lay off?—and the ad could run today.
