space launch vehicle

launch vehicle

Rocket system that boosts a spacecraft into Earth orbit or beyond Earth's gravitational pull. A wide variety of launch vehicles have been used to lift payloads ranging from satellites weighing a few pounds (or kilograms) to large modular components of space stations. Most launch vehicles are expendable (one-use) systems; many early ones were derived from intercontinental ballistic missiles (see ICBM). The Saturn V, which launched the spacecraft that carried humans to the Moon (see Apollo), had three stages (see staged rocket). The U.S. space shuttle system (from 1981) represents a significant departure from expendable launch vehicles in that it is partially reusable—its manned orbiting component is designed for numerous flights, and its solid rocket boosters can be recovered and refurbished.

The Korea Space Launch Vehicle (KSLV) will be the first space launcher of South Korea. It is being built under the authority of the Korea Aerospace Research Institute, the equivalent to the National Aeronautics and Space Administration of the United States.

The KSLV-I launch vehicle is based on the first stage of the Russian Angara rocket and will be built by Russia. The solid-fueled second stage of KSLV-I will be built by South Korea. The launch complex for KSLV will also be built by Russia. It will be capable of launching a satellite weighing 100 kilograms into low orbit. The first launch of KSLV-I is planned for 2008.
