Are Tang, Teflon, and Velcro NASA spinoffs?
Tang, Teflon, and Velcro, are not spinoffs of the Space Program. General
Foods developed Tang in 1957, and it has been on supermarket shelves since
1959. In 1962, when astronaut John Glenn performed eating experiments in
orbit, Tang was selected for the menu, launching the powdered drink's
heightened public awareness. NASA also raised the celebrity status of Teflon
, a material invented for DuPont in 1938, when the Agency applied it to heat
shields, space suits, and cargo hold liners. Velcro was used during the
Apollo missions to anchor equipment for astronauts' convenience in zero
gravity situations. Although it is a Swiss invention from the 1940s, it has
since been associated with the Space Program. |
