What Does EOI Stand For?

EOI stands for Earth Orbit Insertion

EOI, or Earth Orbit Insertion, refers to the critical phase in space missions where a spacecraft successfully transitions from a trajectory that approaches Earth to a stable orbit around the planet. This maneuver typically involves precise calculations and engine burns to ensure the spacecraft achieves the desired altitude and velocity, enabling it to operate effectively within Earth's gravitational field for its intended mission purposes, such as satellite deployment, scientific observation, or communications.
