Tang is a fruit-flavored drink. Originally formulated by General Foods Corporation food scientist William A. Mitchell in 1957, it was first marketed in powdered form in 1959. Sales of Tang were poor until NASA used it on John Glenn's Mercury flight, and subsequent Gemini missions. Since then, it was closely associated with the U.S. manned spaceflight program, leading to the misconception that Tang was invented for the space program. The Tang brand is currently owned by Kraft Foods. Tang was famously used by some early NASA manned space flights. In 1962, when Mercury astronaut John Glenn conducted eating experiments in orbit, Tang was selected for the menu, and was also used during some Gemini flights. The creator of Tang, William A. Mitchell, also invented Pop Rocks, Cool Whip, a form of instant-set Jell-O, and other convenience foods. Tang is sold both in powdered and ready-to-drink form.
