Shuttle-Derived Launch Vehicle

Shuttle-Derived Launch Vehicle, or simply Shuttle-Derived Vehicle (SDV), is a term describing one of a wide array of concepts that have been developed for creating space launch vehicles from the components, technology and/or infrastructure of the Space Shuttle program. SDVs have also been part of NASA's plans several times in the past. In the late 1980s and early 1990s, NASA formally studied a cargo-only vehicle, Shuttle-C, that would have supplemented the crewed Space Shuttle in orbiting payloads.

In 2005, NASA decided to develop the Ares I and Ares V launch vehicles, based in part on highly modified Shuttle components to replace the Space Shuttle, and enable exploration of the Moon and Mars. The agency also studied a third such vehicle, the Ares IV. As of April 2011, NASA's replacement vehicle for the Space Shuttle is an SDV, the Space Launch System.

Famous quotes containing the words vehicle and/or launch:

    You utilitarians, you too love everything useful only as a vehicle of your inclinations—you too really find the noise of its wheels intolerable?
    Friedrich Nietzsche (1844–1900)

    I had often stood on the banks of the Concord, watching the lapse of the current, an emblem of all progress, following the same law with the system, with time, and all that is made ... and at last I resolved to launch myself on its bosom and float whither it would bear me.
    Henry David Thoreau (1817–1862)
