I found this on the NASA Image of the Day web page – check out the haircuts, sideburns, bell-bottoms and leisure suits:
In 1976, NASA’s space shuttle Enterprise rolled out of the Palmdale manufacturing facilities and was greeted by NASA officials and cast members from the ‘Star Trek’ television series.
From left to right they are: NASA Administrator Dr. James D. Fletcher, DeForest Kelley, who portrayed Dr. “Bones” McCoy on the series, George Takei (Mr. Sulu), Nichelle Nichols (Lt. Uhura), Leonard Nimoy (Mr. Spock), series creator Gene Rodenberry, an unnamed NASA official, and, Walter Koenig (Ensign Pavel Checkov).
