What Does TOI Stand For?

TOI stands for Transfer Orbit Insertion

Transfer Orbit Insertion (TOI) refers to the maneuver executed by a spacecraft to transition from a parking orbit, typically around Earth, to a transfer orbit that leads to a destination, such as another planet or celestial body. This critical phase in a space mission involves precise calculations and timing to ensure the spacecraft achieves the appropriate velocity and trajectory necessary for efficient travel to its target, often utilizing gravitational assists or other orbital mechanics principles. TOI is essential for optimizing fuel usage and maximizing mission success.
