Some sub-orbital flights have been undertaken to test spacecraft and launch vehicles later intended for orbital spaceflight. Other vehicles are specifically designed only for sub-orbital flight; examples include crewed vehicles, such as the X-15 and SpaceShipTwo , and uncrewed ones, such as ICBMs and sounding rockets .
Total: Flights which lift-off, or where the vehicle is destroyed during the terminal count Note: only includes orbital launches (flights launched with the intention of reaching orbit). Suborbital tests launches are not included in this listing. Space (regardless of outcome): Flights which reach approximately 100 km or more above Earth's surface.
An orbital spaceflight (or orbital flight) is a spaceflight in which a spacecraft is placed on a trajectory where it could remain in space for at least one orbit. To do this around the Earth , it must be on a free trajectory which has an altitude at perigee (altitude at closest approach) around 80 kilometers (50 mi); this is the boundary of ...

The Mercury-Redstone Launch Vehicle, designed for NASA's Project Mercury, was the first American crewed space booster.It was used for six sub-orbital Mercury flights from 1960–1961; culminating with the launch of the first, and 11 weeks later, the second American (and the second and third humans) in space.

It was the first crewed flight of Project Mercury. The project had the ultimate objective of putting an astronaut into orbit around the Earth and returning him safely. Shepard's mission was a 15-minute suborbital flight with the primary objective of demonstrating his ability to withstand the high g-forces of launch and atmospheric re-entry.
