• Manned missions
The rocket planes experiments started by NACA was taken a step further by NASA which used them as support for spaceflights, the first of which was one-manned and launched by military rockets. When the attention turned to reaching the Moon, the solution chosen was complicated but also the most economical. Supportive projects, both manned and unmanned were introduced and bigger rockets together with spacecraft and moonlander developed. The Moon landing and end of the space race meant a reduction of NASA’s activities. Space stations of a more or less permanent nature, suggested already during the spacerace, were built and an international cooperation was introduced in an attempt to both bring nations together and at the same time share the high costs of space missions. In all, more than 100 manned missions have been made by NASA since 1958.
- X-15 rocket plane (1959–1968)
The NACA XS-1 (Bell X-1) was followed by additional experimental vehicles, including the X-15 in cooperation with the US Air Force and US Navy. The design featured a slender fuselage with fairings along the side containing fuel and early computerized control systems. When the spacerace began the main objective was to get a person into space as soon as possible, therefore the simplest spacecraft that could be launched by existing rockets was favored. This led to the choice of a small capsule spacecraft while rocket plane proposals like a modified X-15 were turned down. Instead X-15 was used for development of techniques and equipment of value for the space missions. This included jets for changing the orientation of a spacecraft, space suits for astronauts and horizon definition for navigation. Nearly 200 flights were made between 1959 and 1968 allowing NASA to collect data vital not only to the spacerace but also the design of the Space Shuttle. The altitude record for X-15 was 354,200 feet (107.96 km).
