// ORBITAL LOGISTICS AND PROPULSION TERM
Injection
Injection refers to the process of placing a spacecraft into its desired orbit, usually after launch, by firing its engines.
TECHNICAL DEFINITION
In spaceflight, injection is the critical maneuver where a launch vehicle or spacecraft performs a final engine burn to achieve its target orbital parameters (e.g., altitude, inclination, eccentricity) after the ascent phase.
BACKGROUND
An aerospace manufacturer is a company or individual involved in the various aspects of designing, building, testing, selling, and maintaining aircraft, aircraft parts, missiles, rockets, or spacecraft. Aerospace is a high technology industry.
