Since 1990, NASA has purchased expendable launch vehicle launch services directly from commercial providers, whenever possible, for its scientific and applications missions. Expendable launch vehicles can accommodate all types of orbit inclinations and altitudes and are ideal vehicles for launching Earth-orbit and interplanetary missions.
Also excluded are payloads that launch on the SLS, such as the Orion crew capsule, the predecessor programs that contributed to the development of the SLS, such as the Ares V Cargo Launch Vehicle project, funded from 2008 to 2010 for a total of $70 million, [98] and the Ares I Crew Launch Vehicle, funded from 2006 to 2010 for a total of $4.8 ...
For the list of predominantly solid-fueled orbital launch systems, see: Comparison of solid-fueled orbital launch systems. Spacecraft propulsion [note 1] is any method used to accelerate spacecraft and artificial satellites. Orbital launch systems are rockets and other systems capable of placing payloads into or beyond Earth orbit.
The Antares rocket is scheduled to launch about 12:40 Saturday afternoon.
Falcon 9 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle [a] designed and manufactured in the United States by SpaceX.The first Falcon 9 launch was on 4 June 2010, and the first commercial resupply mission to the International Space Station (ISS) launched on 8 October 2012.

The carrier aircraft (initially a NASA B-52, now an L-1011 owned by Northrop Grumman) serves as a booster to increase payloads at reduced cost. 12,000 m (39,000 ft) is only about 4% of a low Earth orbital altitude, and the subsonic aircraft reaches only about 3% of orbital velocity, yet by delivering the launch vehicle to this speed and ...
