Lt. Uhura: NASA recruiter

Well, if she's what's waiting in outer space, sign me up!

From the late 1970's until the late 1980's, NASA employed Nichelle Nichols to recruit new astronaut candidates. Many of her new recruits were women or members of racial and ethnic minorities, including Guion Bluford (the first African-American astronaut), Sally Ride (the first female American astronaut), Judith Resnik (one of the original set of female astronauts, who perished during the launch of the Challenger on January 28, 1986), and Ronald McNair (the second African-American astronaut, and another victim of the Challenger accident).

Plus, it's a well-known story, but worth repeating - how Martin Luther King convinced Nichelle Nichols to stay on Star Trek
