What is a launch vehicle?

• A. A wide-bodied passenger jet
• B. A satellite bus
• C. A space shuttle
• D. A rocket-propelled vehicle designed to deliver payloads into space

Answer: (D)

A launch vehicle is a rocket-propelled vehicle that carries and places payloads into space. Its role is to provide the thrust and sufficient delta-v to overcome Earth’s gravity and reach the desired orbit or trajectory for satellites, probes, or other cargo. This differs from an aircraft, which is built to fly within the atmosphere using wings and jet propulsion, and from a satellite bus, which is the spacecraft structure that carries instruments once in space rather than the device that gets them there. It also distinguishes a specific system like the space shuttle, which is one particular reusable launch system, from the general term for any device designed to deliver payloads into space.
