One of the Enterprise's transporter chiefs was played by Mae Jemison, an actual astronaut!

Funnily enough, both Mae Jemison and William Shatner will be in Bloomington Indiana for the April eclipse. Also the musician Janelle Monáe for some reason. And she gets top billing with their names below hers in smaller fonts and her picture bigger than theirs on the advertising. I feel like that does Mae Jemison dirty, but I console myself with imagining the fit Shatner threw when it turned out he didn't get top billing.
