	Sub-orbital spaceflight - Wikipedia, the free encyclopedia
		The sub-orbital spaceflight should not be confused with a partial orbital spaceflight: a low Earth orbit, with deorbiting after less than one full orbit, as in the Fractional Orbital Bombardment System.
		A sub-orbital spaceflight (or sub-orbital flight) is a spaceflight that does not involve putting a vehicle into orbit.
		For more information on the difference between sub-orbital and orbital spaceflights, refer to the article Difference between sub-orbital and orbital spaceflights.

		En este último sentido, la expresión "spaceflight orbital" se utiliza sobre todo para distinguir de los spaceflights secundario-orbitales, que son los vuelos adonde el espacio de los alcances de la nave espacial pero no va rápidamente bastante a incorporar órbita.
		También observar que la velocidad requerida "va" (lograr órbita con métodos sabidos) las mentiras orbitales alrededor de 8 km/s (18.000 mph), mientras que la nave espacial secundario-orbital puede volar solamente en cerca de 1.1 km/s a 1.3 km/s (2.500 mph a 3.000 mph).
