Rocketry was the study of rockets.
Advances in rocketry stemming from World War II continued to shape technological developments into the 24th century. In 2364, Jean-Luc Picard, while playing the role of Dixon Hill, mentioned this to holodeck characters Madeline and Rex upon hearing of Germany's impending invasion of England. Rex, believing the comment to be a sign of "Hill"'s intoxication, wondered aloud whether he ought to let the private detective have any more alcohol. (TNG: "The Big Goodbye")
