The Voyager explorers, which provided scientists and the world with the first detailed pictures of faraway planets, were designed and tested during 1972 to 1977. The two most intelligent machines ever built in the NASA space program, the explorers were launched from Cape Canaveral, Fla., in 1977. Voyager 2 was launched first on August 20, followed by Voyager 1 on September 5.

The increased light-grasp of this telescope made possible many notable advances in structural cosmology between 1924 and 1930, which have revised our ideas about the universe. One of these advances was that spiral nebulae are galactic units like our own; another was the idea of an expanding universe. George Ellery Hale began planning this project in 1906; Francis G. Pease was the chief designer and mechanical engineer. The telescope's mirror support and the use of mercury flotation to reduce the friction are among its outstanding mechanical engineering features.
