An educator in the space industry context refers to a professional who teaches and disseminates knowledge about space science, technology, engineering, and related fields. These educators play a crucial role in inspiring and preparing the next generation of scientists, engineers, and space enthusiasts through various educational programs and outreach activities.

In the aerospace context, "EEE" usually stands for "Electromechanical, Electrical, and Electronic." EEE components are components or systems that are used in aerospace applications and that involve a combination of electromechanical, electrical, and electronic elements.

Deutsch: Effizienz / Español: Eficiencia / Português: Eficiência / Français: Efficacité / Italiano: Efficienza

Efficiency in the space industry refers to the optimization of resources, processes, and technologies to maximize the performance and success of space missions while minimizing costs, time, and energy consumption. This concept is crucial for the sustainability and advancement of space exploration and operations.

EGNOS stands for European Geostationary Navigation Overlay Service. It is a satellite-based augmentation system (SBAS) developed by the European Union that enhances the accuracy and reliability of GPS (Global Positioning System) signals, mainly for aviation and maritime applications.

Electrical ground support equipment (EGSE) refers to the specialized equipment and systems that are used to support the testing and maintenance of aerospace systems, particularly those that are electrical or electronic in nature.

Deutsch: Ausstoßung / Español: Eyección / Português: Ejeção / Français: Éjection / Italiano: Espulsione

Ejection in the space industry context refers to the process or action of expelling or releasing a spacecraft, satellite, or any other payload from a launch vehicle or parent spacecraft. This can occur during various phases of a space mission, such as deploying satellites into orbit, ejecting landers or rovers toward a celestial body, or discarding used stages of a rocket. Ejection is a critical operation that must be precisely timed and executed to ensure that the payload reaches its intended orbit, trajectory, or landing site. The mechanism and method of ejection vary depending on the mission design, the type of payload, and the specific requirements of the operation.

In the aerospace context, electricity refers to the flow of electrical charge, typically through wires or other conductive materials, to provide power for various systems and equipment.
