"May Jemison, US astronaut: ""A point of geeky coolness: Jemison appeared in an episode of Star Trek: The Next Generation after LeVar Burton discovered she was a fan and invited her to take part. That makes her the first real life astronaut to have featured on the show. It's a neat bit of circularity, given that Jemison cites Nichelle Nichols's performance as Lt. Uhura as one of her motivations for joining NASA."""
