Project Mercury

Project Mercury was the United States's first successful manned spaceflight program. It ran from 1959 through 1963 with the goal of putting a man in orbit around the Earth. Early planning and research was carried out by NACA, while the program was officially carried out by the newly created NASA. The name Mercury comes from the Roman god (it is also the name of the innermost planet of the solar system).

Boosters

The Mercury program used three boosters: Little Joe, Redstone, and Atlas. Little Joe was used to test the escape tower and abort procedures. Redstone was used for suborbital flights, and Atlas for orbital ones. Starting in October, 1958, Jupiter missiles were also considered as suborbital launch vehicles for the Mercury program, but were cut from the program in July, 1959 due to budget constraints. The Atlas boosters required extra strengthening in order to handle the increased weight of the Mercury capsules beyond that of the nuclear warheads they were designed to carry. Little Joe was a solid-propellant booster designed specially for the Mercury program.

The Titan missile was also considered for use for later Mercury missions, however the Mercury program was terminated before these missions were flown. The Titan was used for the Gemini program which followed Mercury
