I came across this photo in the NASA on The Commons profile on Flickr and it is awesome. Here is the caption for the photo that explains what is happening here:

The STS-54 crew of the Space Shuttle Endeavour (OV-105) in their official “gag” photo costumed as the bridge crew of Star Trek’s United Federation of Planets Star Ship USS Enterprise (NCC-1701) as depicted in the movie “Star Trek II, The Wrath of Khan”. The photo was taken on the Star Trek Adventure set of Universal Studios California theme park in Los Angeles, California while the crew was on a west coast training/public relations swing to TRW Corporation in Redondo Beach, CA during the Summer of 1992. TRW was the manufacturer of the STS-54 mission’s primary payload, a Tracking and Data Relay Satellite (TDRS-F or TDRS 6). From Left to right: Greg Harbaugh (MS2/Engineering Officer), Mario “Spock” Runco Jr. (MS1/1st Officer/Science Officer), John Casper (CDR/Captain), Susan Helms (MS3/Communications Officer), Don McMonagle (PLT/Navigation-Helm Officer).

I love that Commander Mario Runco Jr actually looks like a Vulcan. He is even a scientist.
